Sounds Great Bill.

Any upgrade path for version 2 owners?

I folow Socomon,

I saw on the micropower V3 a "tx port" does that mean telemetry is on the way?

But, I am glad that you put the LCD on the bottom so the USB cable can be plugged in without having to unplug the LCD ;)

[jknust]

I JUST bought a V2 from Tower (hasn't even arrived yet), is there an upgrade path/exchange, or do I need to just do a return/swap with Tower? I can wait until Nov 15 for V3.

Thanks.

[billpa]

HI All,

Thanks for the feedback. Ha, we've got some work to do with that photo it appears. :-)

Re upgrade path, we generally offer that for products that we can phsyically upgrade (like the non-firmware upgradable FDR to upgradable version).

In the case of the MicroPower, the units cannot be physically upgraded (different PC board, microcontroller, components, etc.). This means that in your hands the V2 is a great, extensible logger for which we will continue to offer new sensors and software enhancements. But in our hands its a paperweight. :-)

Send it back!!!

[bobskinner]

I too have a V2 on the way to me, my questions is regarding the

"Greatly increased resolution/accuracy"

Where does this come in to play? Is current still only accurate to 0.1A or has that been improved? Are the basic function and accuracy/resolution regarding Volts and Amp measurement still the same? If they are then I'll keep the V2 as I don't need the higher Voltage and current features.

Any feedback would be greatly appreciated.

Bob

[sboub]

100 or 150A through Deans connectors? Seems to be too much...

[Basingstoke Roy]

Hi

Any chance that the V3 will be able to use the Electric Expanders to give a second current measurement?

Two RPM's is a good step forward for uses with my contra rotating brushless motors, but two current measurement would be even better. :)

It'll also have an expanded memory. I can only log like 30 minutes on mine :( :rolleyes:

When they supposed to be out?

[Hugeone]

Being able to daisy chain many micropowers to synchronise their data would be icing on the cake...

-Hugo

[numb_thumb]

It will be better if there is a rebate or someting like that for exiting V2 owners who would like to get a v3.

My two cents. No offences intended.

Happy Flying !!!

Most things you buy in this hobby are not upgradeable in that way. WHen I bought a Spektrum DX6, they did not offer an upgrade path to the DX7 when it came out. Same with motors, servos, ESC, etc. As long as the continue to support the firmware and accessories, I think that is all you can really expect. Of course, There is never any harm in asking. ;)

My $.02.

[flightmare]

Wow, I did not expect such and answer.

I believe this will turn off many of your support base. Its the V1, V2 users who supported you with buying the product and provided feedback that prompted for V3. I don't think it is fair to drop them like orphans without an upgrade path to V3.

My two cents. No offences intended.

Happy Flying !!!
well said//
I can't believe that they won't credit the first generation users who went through the PIA magnet sensors or the optic sensors..They never seemed to work right,but we kept on hoping for a better product..

what about the users who have continued to buy the the new sensors ie brushless rpm sensor,altimeter expander,airspeed expander multifunction expander,logging memory expander...At 30.00 a pop,that is close to 120.00 in the last few months..I have continued to support eagle tree systems for 2 years..Come on Billpa,I know you don't want to lose us to MR,who also feature a thrust sensor..I dont want a strait trade Bill,just something to show you do appreciate the beta testers.

Currently it is 0.12A and 0.07V, if I remember correct. I also hope this is improved as it will make it more useful for bench testing motors and give more accurate mAh display among other things...

Fred

[StarmanDXE]

Oh? Is the mAh reading not accurate?

I understand you have the elogger for quite sometime and you must have reclaimed the value out of it.

It was just a thought. No offences intended...

[Socomon]

If you really think you are missing out on features then sell the V2 in the forums now and buy the v3. You won't loose much money at all in the process.

FWIW - my motors and ESCs often go from one plane to the next when I get tired of the first one.

Steve

[flarssen]

Oh? Is the mAh reading not accurate?
Depends. When flying with mixed current draw, it's probably OK. The problem is when charging/discharging with a constant current. Then the accuracy of the mAh reading depends on how close this current is to the "steps" created by the current resolution. Higher resolution will give better results, especially for smaller currents.



Fred

[StarmanDXE]

Gotcha. Is the current resolution a setting you choose yourself? Above you mentioned something about 0.12A. So, over the course of an hour, you'd be off by a max of, what, 60 mAh?

[th3tick]

Darn. I didn't even get a chance to make the two suggestions I had:

1) clock timestamps on the data
2) model recognition when you plug it in

I am glad to see that the USB plug is on the outside this time, but still wish it was a mini-USB instead of a four-pin connector.

I've got one on each of my three helis, and in fact, a brand new v2 that's only been installed a week/has yet to fly. It should still meet my needs, so while I'd love the new, the old looks to still fit my needs.

It looks like it's thicker, and thus implies that it's heavier. Are there any weight comparisons between the v2 and v3?

John

[flarssen]

Gotcha. Is the current resolution a setting you choose yourself? Above you mentioned something about 0.12A. So, over the course of an hour, you'd be off by a max of, what, 60 mAh?
The resolution is not selectable by the user, at least not in the old unit. Offset might be in the range 0-120 mAh over one hour. Maybe someone could give us the resolution of the new, improved version??

Fred

[billpa]

Hi All,

Sorry for the delayed reply.

The internal resolution of the V3 is approximately 0.05A and 0.02V. There are also several enhancements to attain better accuracy and maintain it over time.

Regarding upgrade, the most important thing to us is to have happy customers. Based on your feedback, we've decided to offer a V1/2 to V3 upgrade rebate of $10. This is about a 15% discount for customers who continue to support us. And you get to keep the V1/V2!

To take advantage of this rebate, purchase your V3 from any authorized dealer or direct from us. Within 30 days of receiving the V3, mail in a copy of your V3 and V1/V2 purchase receipts, and we will mail you (or paypal you at your option) the $10 rebate. Rebate requests should go to:

Eagle Tree Systems, LLC

[numb_thumb]

Bill, Thanks for the rebate offer. Though 10 dollars may mean little for few, your offer to keep the v1/v2 will enable to sell it for half price and that combined with 10 dollar rebate will make the upgrade to V3 worth every effort. Thanks again.

Happy Flying !!!

[cmulder]

if anyone likes to sell there now "outdated" v2 for a good price let me know ;)

[Al M]

Mine does what I wanted so I can hardly call it outdated.

[Socomon]

Bill:

Tower has the page up for pre-ordering V3:

http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXTFS1&P=7

Do you know if this will be the Deans or wire lead version? Will Tower be carrying both?

Steve

Edit - I figured out that is the code for the Deans version. Have they ordered the leads version from you?

[JIM CALDWELL A]

Bill, the Deans are just used for reading the voltage now? the amps are taken with the hall ring sensor now?
where does the amp lead plug into the recorder, Temp pins?

[StarmanDXE]

My guess would be that it just reads it inside the logger with the hall ring sensor. I doubt they would build it so you need to rig something else up just to read the current... :o

[JIM CALDWELL A]

I hope not.

[billpa]

Hi All,

The hall sensor is integrated inside the logger, just like with the eLogger V2.

Regards,

Bill for Eagle Tree

[Yellowsierra]

Hey Bill,

I noticed you have a 100 amp and 150 amp version. Will the 100 amp only handle 100 amps or does it only read up to 100 amps. The reason I ask is because my combo may pull around 100 to 105 amps.

Justin

[billpa]

Hi Yellowsierra,

The 150 amp version has much heavier wire leads. I can't really recommend running more than 100 amps through the 100 amp version, so this would be at your own risk. As always, you'd want to do a bench test similar to an actual flight to verify everything.

Regards,

Bill, for Eagle Tree

[kristjane]

Hi!
Still no Mini USB port on logger?

I have V2 logger, that I have to send back to HC, because of malfunction. At beginning all worked great, then it got mad, voltage was too hight, current 0A, everything else works ok. Will be still V2 possible to get and will old sensors work with new V3 version, because I have multi expander and two temperature sensors at home?

Thank you and have a nice day!
Kristjan

Regards,

What's the difference in actual measured resistance between the 100A and 150A versions?

[billpa]

Hi eajohnson,

Other loggers/wattmeters on the market use a resistance shunt to measure current, which does indeed add resistance. We use a hall effects sensor to measure current, so there is essentially no resistance. The hall sensor costs us a lot more, but is worth it in my opinion. The resistance of our hall sensor is 0.00013 ohms, regardless of amperage.

That's the answer I wanted to hear, 0.00013ohms is in the 'would never be able to tell it's there' category , maybe 1.5W loss on a 3000W setup? Can't wait for these to ship.

[StarmanDXE]

What's the resistance like for the V2, then? :(

[billpa]

Exactly the same. :-)

[StarmanDXE]

I thought you said it uses a shunt resistor? :confused:

[bobskinner]

I did not cancel my order of the V2 and received it a few days back as I needed the logger urgently. It is quite cute, the soldering work was a little shabby on the current sensor and other than a bit of recalibrating on the voltage and current measurements it seems to be working well.

Bill, is a different hall sensor chip being used on the V3 or will it be the same one that is on the V2? I recognized the chip as I have a couple of them lying in my toolbox from a past project. If a new sensor is being used would it be possible to say which chip as the datasheets would offer some useful info on expected accuracy of the hall sensor, I might still be considering buying the V3.

Thank you,

Bob

[StarmanDXE]

Bill, is a different hall sensor chip being used on the V3 or will it be the same one that is on the V2?I guess that means the V2 uses a hall sensor? :o

[billpa]

Hi All,

Yes, all our products use a hall sensor of one form or another.

The V3's Hall sensor has somewhat improved specs, but in reality the tolerances of individual components are factored out by our per-unit calibration procedure. The increased resolution of the V3 will be more "impactful" than the sensor hardware change.

Regards,

Bill, for Eagle Tree

[Yellowsierra]

Hey Bill,

Is the Version 3 about ready to ship? I really want a datalogger but dont want to buy the V2 since the V3 is coming out.

Thanks

Justin

[Socomon]

I thought I saw the date was pushed back to Dec. or January due to a manufacturing issue. Bill, please give us an update of when you expect you will have them and when Tower might have them.

Steve

[13brv3]

I noticed the Eagle tree web page just changed from Nov 15th to Nov 30th for availability.

Rusty

[billpa]

Hi All,

We are shipping the first (small) batch of eLogger V3's starting today. If you ordered one early in the preorder cycle, you should get yours this week.

Our next batch of eLoggers is due in at the end of November, and that should be enough to fill the orders we have right now.

Regards,

Bill, for Eagle Tree

[Socomon]

What about Tower?

[Yellowsierra]

I gave up on the V3 and just ordered the V2. I guess I will bye the V3 lator...

Justin

[numb_thumb]

Bill or anyone,

What's up with the theories about elogger that say you have to place the airspeed expanders in a neutral pressure area?

I can understand (although I'm yet to believe) that if you place the expander in a high pressure area (such as where there is direct flow of air) then you will get less numbers than actual.

However I don't understand how a low pressure environment could form inside the fuselage??? I have enough air intakes in all my planes for good ventilation. At high speeds a decent amount of air gets inside the fuselage to take away some of the heat.

In theory it would be awesome if the airspeed expander could read the air pressure the moment when it is turned on and store it and then use that as an baseline to calculate the airspeed when the plane gets in the air. This way we don't have to nit pick on things like low pressure, high pressure et al.

[dhares]

This is a long answer, but here goes. Airspeed is calculated using pressure differential. Reading atmospheric pressure on time on the ground isn't enough, since altitude and other things have a very real effect. In real airplanes, pitot tubes have pressure and static ports. See http://www.grc.nasa.gov/WWW/K-12/airplane/pitot.html for complete details. The difference between pressure on the two ports can be used to calculate airspeed. Bill made his life easier by using a sensor with an internal static port. He assumes that the static pressure port is seeing atmospheric pressure similar to what a real pitot tube's static port would read. Nice idea, but not realistic in electric models where we force air into the planes for cooling. I've used the following techniques to solve the problem:

1) Put the Microsensor and the pitot tube out on a wingtip. Put the sensor under the covering in a closed compartment and route the pressure line to it. The compartment is leaky enough that it will read atmospheric pressure without itself becoming pressurized.

2) Put the microsensor inside a small container of some sort. Run the wires and two tubes out of the container. One tube connects to the pressure sensor, the other just stops near the pressure sensor. Seal the container. Connect the tube going to the pressure sensor to the tube Bill gives you, and place it in the airstream. Run the other tube to a neutral pressure area. I can post a diagram/picture of this if anyone's interested.

These techniques get the airspeed to correpond to GPS airspeed within 5%, when compared to an FDR Pro flying in the same aiplane at the same time. Or just get an FDR Pro - they have both pressure and static ports so you can build and use a real pito tube.

[diver don]

What about Tower?

Is Tower on your list?

[billpa]

Hi All,

Dave, thanks for the great writeup.

One additional method (sealing of the sensor) is covered in the "troubleshooting" of the airspeed microsensor manual.

This looks a lot more difficult than it is - takes about 2 minutes to do.

I'm not sure if that is a question addressed to me or to Eagle Tree. Tower's website indicates that they will be getting the V3 product in at some point. but Bill has been unwilling so far to comment as to when.

[billpa]

Hi Steve,

Sorry for the confusion. The first large production run of eLogger V3's is due in-house at the end of November, and all distributor and direct orders will be filled at that time.

Thank you Bill. My assuption based on that would be that Tower should have them early to mid December. I am hoping to get a 100 amp wire-leads version from them.

I tried the approach in the manual first. It works OK, but I had trouble getting a tube under the shrink wrap without damaging it (the shrink wrap). I finally used a piece of your pitot tube materal to slide in, not flexible hose. That gave me a connection point too. I dabbed everything up with silicon caulk and got results +/- 20% of GPS. I stripped silicon and heatshrink and put everything inside a pill container and got +/- 5% of GPS. I'd recommend the pill bottle approach if you can tolerate the size and 1/4 oz weight. One other benefit ... with the most pill bottles you can slide the altimeter expander right in too, back to back with the airspeed sensor, and let it use the same static pressure. Otherwise you have to deal with it too.

Dave

[13brv3]

Guess what showed up in the mail today :p

I haven't tried it yet, but it looks great :D

Thanks,

[dhares]

Mine came yesterday too. It's cold (24 f) and windy here, but I stuck it in my SuperVee and went to the pond this morning. Works great, but I noticed my packs don't get as hot as I expected. Wonder why? Maybe if I hold 'em I'll warm up. Geat job Bill. Now if only the Lions do as well against the Packers.

[diver don]

Ho, Ho, Ho,

Thanks Bill

I'm working on the TF B-25 and want to use the duel RPM feature.

Don

[dhares]

I'm not shilling for Bill, but...

Whenever I've had a twin, I've been unhappy with the micropower units (unless I use two). I always want more data than I can otherwise get. Both RPM, both motor currents (electric), both exhaust temps (gas), etc. Plus all the servo stuff. If I had a spektrum radio, I'd want that data too. So I use the full size FDR for twins. My 2 cents

[Truglodite]

bill, i just got my v3 & have 3 quick questions for you:

1) under "advanced hardware options", there is a checkbox for "i want high resolution rpm". what is that for? i tried it & get invalid data with my brushless sensor

2) under "advanced hardware options", there are checkboxes for "low temp option". what are they used for? fyi, i have the micro temp sensor (250Fmax).

3) does the rpm logged from a brushless sensor change depending on the # of poles entered, or is the software interpreting generic data based on the number of poles entered? ie: if the logged data is generic, then the number of poles only needs to be set correctly when displaying the rpm data.

thanks in advance,
kev

[wazzer]

Subscribed

[billpa]

Hi Truglodite,

Thanks for your purchase. Those particular advanced options are not are not supported/tested options with your equipment. We generally use that "advanced" page for custom projects. The 'low temp' option is used to measure temperatures down to about -150 degrees. Don't ask me why. :-)

Correct, the logged RPM data is generic, except that the powerpanel will display incorrect data if the # poles is not set correctly when the data are captured.

Bill, for Eagle Tree

Right on Numb_thumb.........Any vendor of accessories who does not look after his customers who have invested in this hobby with their hard earned cash does not deserve our suport.

Sure there are ways to make us feel better by offering a discount on product that is "only a paper weight" out of date. Telling us that the old system will be supported...........but no end date mentioned is just a scam as Eagle Tree may have issues trying to sell old product through Tower etc...

Note..Only the vendors with integregity in this hobby will ensure we keep coming back by being fare and honest in their dealings with us .

Eagle tree were eager to inform me of the accessiories I did buy for my V2 unit and now they tell me it is a "paperweight in their view = No Value to them.

[th3tick]

I'll buy that line of reasoning just as soon as Align offers me a way to upgrade my T-Rex 450 to a 500...

[billpa]

2) A couple of the pins on my v3 were bent on arrival. I straightened them out ok, but it does remind me that they are fragile and exposed. You mentioned quite a while back, that you had some kind of pin cover you were working on. Anything come of that?

I LOVE these data loggers and they've REALLY helped me characterize power usage as well as evaluate claims from the multitude of battery vendors that I use for electric-powered auto & heli applications.

I also have had issues with the pins being exposed. In one case, the V2 unit somehow got knocked free of its mount, but the worst part was that it banged around hard enough to bend four pins to where they touched each other. After several races I went to download the info and only one session was logged. To make things worse I couldn't log anything else any more. I re-flashed the unit with the 5.15 firmware (included with the beta software) and all is now well again!

It would be preferable that the unit has female connectors and the male connectors be a part of everything else connecting to the unit. I'm sure EagleTree considered this when making the units (btw, thank you for the built-in Deans) so there's possibly something that I didn't think about that made them go that route.

I've attached some pics showing a quick 5-minute improvisation that has changed my experience completely - complete protection of the pins when in use. It atts a few mm to the length, but it's worth it.

Obviously, when I start connecting various sensors this won't work, but I'm going to place a female-female connector and the sensors will be converted to male to keep the logger safe. It's not much work, but it makes my life better.

I look forward to learning if EagleTree is considering any of these points?

Thanks,

Jeff

p.s. The Beta version allowed me to successfully read and graph previously saved log files.

Thank you for sharing your solution. Bill has been somewhat selective in responding to questions. Perhaps he is busy and doesn't catch every post.

HI Helishack,

Thanks for the post and the good suggestion. We have been working on something similar to cover/protect the pins, but this has been going slowly. It is something that we know people want and we will figure something out!

Bill, that's GREAT support - thank you for the feedback. I look forward to seeing what EagleTree comes up with.

Hi!
Still no Mini USB port on logger?

I have V2 logger, that I have to send back to HC, because of malfunction. At beginning all worked great, then it got mad, voltage was too hight, current 0A, everything else works ok. Will be still V2 possible to get and will old sensors work with new V3 version, because I have multi expander and two temperature sensors at home?

Thank you and have a nice day!

I was getting ready to post a solution for a mini-usb interface and saw the above post from about 4 months ago.

I'm currently putting together a protective case for my datalogger, but in the meantime I added a mini-usb port and find it extremely convenient - especially since I use mini-usb for several functions related to hobby products. Now I can use a single retractable mini-usb cable for basically everything on my workbench.

Below is a pic of what I'm referring to - it works flawlessly! I should have a final case picture later this week - with the datalogger+mini-usb connector mounted in the case.

I have just received the V3 logger from HC, and really looking forward to getting some in-air data from my planes.

One thing though, I was planning on recording multiple flights on multiple planes with different motor poles and from what I understand, the logger needs to be programed prior to each flight if the motor poles are different.
Or is it possible, using the brushless rpm sensor, for the raw RPM data to be logged then filtered accordingly once the data is downloaded to the windows software?
I have planes with 6, 12, 14 and 2 poles.

Also, logging just amps, volts and RPM at a resolution of 8 per second, what is expected record time?

Regards,
Paul.

Hi Paul,

Well, I have some "sort of good" news for you. The raw data in the logger does not change.

If you set the pole count to the first model in the software, then download the data, the data for the first model will be correct. And, this sequence can be repeated for each model, as long as you can remember the sequence of models you flew. Not perfect, but hopefully will be workable for you!

Record time for those settings would be on the order of an hour+ I believe.

One thing that would sure help is if the logs were each wall-clock time/date stamped. It sure would make sorting such data out a lot easier...

Just an RFE for the v4 ;)

Hi John,

If you use our GPS with the eLogger, the logs are time stamped. We can also add the date if people want it.

All, I wanted to let you know that our latest units have the label installed *under* the heatshrink. Sorry it took us so long to realize the obvious! :-)

Regards,

Bill, for Eagle Tree

[Socomon]

Yup - now that makes sense.

[Geni]

Hi Bill
I would find it good if the head of the logs the date and time would be.
To correct the time you need to have read the country setting or in the program settings retrieve and store the timezone (for me GTM +01:00)

PS: In the moment is the GPS-time not Realtime

[billpa]

HI Geni,

We could easily add the DOWNLOAD date/time to the top of the file, if that would help. Even if there is no GPS, that would be correct.

Regards,

Bill, for Eagle Tree

[Geni]

Hi Bill,

Not exactly my wish is:
For download without GPS, system time and date at the beginning of the file.
For download with GPS, in each record the corrected GPS UTC Date, Time, "rather than the garbled" GPSUTC UTC, converted to milliseconds. Example: 55928839 "-> new hhmmssddmmyyyy

according to "NMEA 0183 "
http://www.gpsinformation.org/dale/nmea.htm#ZDA (http://http://www.gpsinformation.org/dale/nmea.htm#ZDA)

$ GPZDA, hhmmss.ss, dd, mm, yyyy, xx, yy * CC
$ GPZDA, 201530.00,04,07,2002,00,00 * 60

where:
Hhmmss HrMinSec (UTC)
dd, mm, yyy Day, Month, Year
xx local zone hours -13 .. 13
yy local zone minutes 0. .59
* CC checksum

Will future software make my new e-logger v3 support the g-force extender?

I have just bought both from HC. It was not obvious to me that there are different eagletree product lines.

Hi Torben,

Thanks for your purchase! I am not sure yet whether that will happen. Sorry I can't give more precise info.
