Announcing the MicroPower e-flight recorder from Eagle Tree - ONLY $69.99

[billpa]

Since Eagle Tree released the first mass produced model airplane data loggers a few years ago, we have often been asked to come out with a unit that is even lighter and (frankly) cheaper than our full featured units. Also, many people have asked for a way to see their data live AND log data in the same inexpensive system.

We are pleased to announce the new MicroPower USB e-logger system, the first system which will meet both these needs, with the base unit PRICED AT $69.99!

The MicroPower has several of the key features of it's more fully featured cousin, the USB Flight Data Recorder, at a size and price point that meets the needs of more cost and weight conscious pilots.

Here are a few of the features of the MicroPower:

* Logs pack current to 100 amps and voltage to 45 volts right out of the box
* Accepts optional inexpensive ($9.99) sensors for temp and RPM
* weighs about 0.5 oz
* supports adjustable logging rate, and has lossless data compression for max logging time
* comes with our state of the art Windows display and graphing software
* supports USB Live Mode, which lets you see what's happening in the model LIVE on the bench, on your PC
* has app updatable firmware - if we add a new feature or (heaven forbid) have a firmware bug, the update is just a download away!

Best of all, the MicroPower fully supports our soon to be available PowerPanel LCD Display module. This ultra thin LCD display connects to the MicroPower (and of course the FDR) with a 4 wire cable, and lets you get your max or live power displayed without a PC, just like the heavier, non-logging WattMeters on the market. The PowerPanel is so light that it can easily be attached to the side of your model for live/max display all the time!

The MicroPower system comes with everything you need (logger, USB cable, CD, manual) and is scheduled for release in early November, just in time for Christmas!

Are they shipping yet?
Are they going to be available thru your site only or do you have dealers?

Thanks,

Hi Larry,

Hope you got as much sun as we did in Bellevue today!

The unit is scheduled to ship in early November. It will be available direct, thru dealers, or from Tower.

Now that's VERY interesting.....

What got omitted from the regular FDR? Or, have you kept the pitot/static system for indicated airspeed capture? What about expansion (specifically the just-released GPS module)?

I may be sending you a long email full of questions soon.....:)

[billpa]

Hi BEC,

The MicroPower will NOT have the following features that are available on the FDR and FDR Pro:

* Wireless Telemetry capability
* Airspeed
* Altitude
* GPS
* Servo position and glitch recording
* GForce
* EGT
* Fuel Level
* Additional RPM Inputs

The FDR (FDR PRO) also has 4x (16x) the memory of the MicroPower, to accomodate the larger # of parameters.

Hope that helps!

Bill Parry

[BEC]

Drat - if it could do airspeed it would've been just about perfect for at least one application I had in mind. Still, very intriguing at that price point and it sounds as if there are a number of possibilities.

So, it's similar in capability to a very lightweight Medusa Power Analyzer Pro - volts, amps, RPM, two temps....what else?

Without the servo logging and the requisite Y-harnesses installation should be much simpler.

[billpa]

Hi BEC,

Have you noticed that everyone on this thread is in WA? Weather's too lousy to fly here now, so we must all be dreaming about it. :-)

Airspeed adds a big chunk of expense, so it's one of the items we left off.

I'm not very familar with the Medusa, but here's the list of features of the MicroPower (lemme know if there are any software features we should add!):

* Logs pack current to 100 amps and voltage to 50 volts
* Accepts optional inexpensive ($9.99) sensors for two temps and RPM
* supports adjustable logging rate
* comes with Windows display and graphing software
* supports USB Live Mode, which lets you see what's happening in the model LIVE on the bench, on your PC
* has app updatable firmware
* fully supports our soon to be available super-thin PowerPanel LCD Display module.

It sounds very cool.

What is the max sample rate and recording time?

I would assume higher rates = less recording time?

Where else would anyone WANT to live ;)

Larry

[LTChip]

So this could be used to monitor in flight unloaded amp draw?

[billpa]

Larry: agreed on WA! And, max logging sample rate is 10 s/s for the MicroPower. But, some params are polled much faster than that and averaged. Since we are compressing data heavily, record times vary, but at 10 s/s with RPM, temp, current and voltage, 30 minutes would be typical.

LTChip: Yes, absolutely! This is one of the key things the device is for.

[BEC]

Bill,

Yes, I did notice..... and it's very nice and flyable outside right now, and I'm in here. *sigh* Norm's retired - he might just be out flying right now if the weather on Whidbey looks like it does here in Renton. :)

So, just to be clear, since you basically gave the same list again as in the first post - this new unit logs five parameters only: voltage, amperage, RPM, temperature 1, temperature 2, and to do that would require $30 worth of additional sensors. The basic unit can log voltage and current only, out of the box. None of the other parameters from the original FDR - say the voltage of the receiver supply.

Windoze software could/would calculate power, perhaps battery capacity used, that sort of thing.

So this is really more comparable to the BNB Digital Power Recorder (http://www.bnbproducts.com/pages/features.htm), with a wider voltage range and the ability to also capture RPM. Hmmmmmmm.....

[Larry3215]

Looks like more features and wider recording ranges for a good bit less money. Addons are less too.

If you start a waiting list - put me on it :)

Larry

[billpa]

BEC,

Yes, nice weather today! I caught a glimpse of it thru the window. :-)

Yes, the unit logs the params you list. It's primarily intended for e-flyers, so we are making the other params optional to keep the price at an accessible level. We've gotten a lot of customer feedback that these are the things that e-flyers want most. Lemme know if you think we should re-configure the options, etc.!

Our software already calculates/displays/graphs power, amp-hours, volts, etc. I've attached some screenshots below.

Larry, thanks for the kind words!!

[Neil Walker]

Looks cool. How are the current and voltage recorded, i.e. is it connected "in-line" with the power system?

[Microbatman]

If possible

Please make the graphic resolution that measures volts with 1/10 volt resoulition.

In other words X Y cordinates graph
Make it so the voltage resolution is not in 1 volt lines
So if you wanted to monitor a 9 volt line in the sand the next line up would be 9.1, 9.2 9.3 9.4

That way we get a very good measurment about the battery performance.

Hope this helps

Thank You.

[bobf]

Can we set the scale for the temperatures etc on the graph. I would want finer resolutions than you show.

[billpa]

Microbatman, yes, the resolution will go down to 1/10th volts on the graphing, since the displayed graphing area can be zoomed.

Bobf, yes, same as above. You can zoom in on particular areas using the cursor.

Let me know if that doesn't clear it up!

[Neil Walker]

Looks cool. How are the current and voltage recorded, i.e. is it connected "in-line" with the power system?

Sorry for re-posting but maybe this Q got missed. Is it connected in-line with the power system, i.e. between the ESC and the motor? Or is it powered seperately and uses a ring-style sensor and voltage probes? Advantages and disadvantages to both. The former is definitely easier but also creates another single point of failure for your entire system... especially if you don't have separate power to your Rx.

[billpa]

Hi Neil,

OOPS! Sorry about missing that question. The new MicroPower unit is in-line, and the FDR unit uses a ring style sensor. As you say, both have tradeoffs.

I am being picky and lazy but can you save the default scale for the graph?

Microbatman, yes, the resolution will go down to 1/10th volts on the graphing, since the displayed graphing area can be zoomed.

What is the lowest voltage it will record data with. Will it would with 2 cell lithium packs?

[fly_boy99]

Bill-

Wow this is something I've been looking for. The only things I would like for the system to be able to be upgraded to or added on would be altitude and speed sensing. Otherwise a great setup at a great price!!!

It's on my Christmas list already!!! ;)

[billpa]

HI fly_boy99,

Sorry for delayed reply - Mondays are always exciting here. :-)

Are you familiar with our FDR product? Here's a link to it:

http://eagletreesystems.com/Plane/plane.html

It's $169.99, and measures Airspeed, Altitude, RPM, Temp, servo positions/glitches, and RX voltage right out of the box. It also has options for Current/Voltage, GPS, G-force, EGT, Fuel level, multiple RPMs, and wireless telemetry.

The FDR may be what you are looking for if you need airspeed and altitude. It would get very messy to try to have altitude and airspeed as add-ons to the MicroPower product, since those sensors require tight integration into the main unit to get good accuracy.

Bill Parry

Bill,
Could the Hall effect current sensor from the FDR unit be made to work with the Micropower unit and would it be possible to increase the max current capability to 250 Amps?
I could then see the Micropower unit becoming popular with the High performance, F5B and F5D markets, for drive system optimisation. The FDR unit is too big to fit these planes and a none intrusive current measuring system would be much preferred.

Dave

[billpa]

Hi Dave,

Thanks for the feedback.

We will be able offer versions of both the FDR and the MicroPower that will go to 200+ amps, I believe.

One note: the FDR can be removed from its case, which greatly reduces the footprint. The Micropower is even smaller than the FDR without its case, however.

Can you send me some maximum dimensions for your planes, in terms of the largest board you can fit?

Regards,

Bill Parry
Eagle Tree Systems

[BEC]

One more silly question for the public forum: will the MicroPower come with connectors on the power leads? If so, which ones? (Personally, I'd say "don't")

[billpa]

Hi BEC,

The unit will initially have Deans style plugs, but those can be removed of course. We may opt later for just bare leads if that is more desirable.

Regards,

[Larry3215]

Since I hate Deans and only use Anderson PP, Id vote for none :)

I think most F5B competition planes would struggle to find room for anything larger than about 30 x 20 x 10mm. That's about the same size as the Schulze 835W or Berg 6 receivers with wires coming out of the end. I'm not sure about F5D pylon racing models but they have even less spare room, maybe 30 x 20 x 5mm.

Is the switch to in-line current measuring from the ring type sensor of the FDR a cost thing or a technical/ design limitation of the new unit? If it is to keep costs down then maybe it could be offered as an add on.

Dave

[D Dixon]

Hi Bill,
Two more questions....
Is the rpm sensor going to use the magnets and Hall sensor like the FDR unit or could you make it work with an optical sensor? I'm thinking an optical sensor would be much simpler for the end user to install or switch from model to model as most electrics have some form of cooling duct for the ESC just behind the prop.
I noticed on the graphs you posted that the temperature is in Fahrenheit and wondered if it is possible to choose a Centigrade display if preferred?

Dave

[BEC]

Since I hate Deans and only use Anderson PP, Id vote for none :)

Larry

Ditto on both counts. THat's exactly why I asked.

Will the software for this run under Virtual PC 7 and Windows XP on a Mac? I've gotten the Medusa PowerPlusView to run and talk to my PA-II from my Powerbook......which is the laptop I have.

[green66]

Does the Electric Expander module add all the functionality of the MicroPower recorder to a RT Dashboard or FDR system (Glide System in my case)?

[fly_boy99]

Thanks for the info but I really don't need to spend the extra $100 bucks to get that as I have another way to figure it out with a 9.99 add on!!! :)

When are they due out???

Hi All,

Sorry for the delayed reply. We had a firedrill here with another product that kept me away from anything fun. :-)

Here are some much belated answers to the questions:

Green66: yes, the FDR and electric expander has a superset of the Micrologger features.

BEC: I am not sure yet about VPC 7. We are working with a customer of our FDR product, trying to get that to work now, and if one works the other will.

D Dixon: Yes, both hall and optical sensors will work with both the Micrologger and our FDR products . We've had a background project for several months to come out with an optical sensor that works well in lots of different environments. Optical sensors seem to work very well for lower RPMs, but not always well at higher. Yes, metric is fully supported. Re using inline vs ring sensor, cost is the biggest issue. The ring sensor is quite a bit more expensive than inline, but I'm hoping somebody eventually comes out with a reliable, low cost ring.

Larry: The micrologger unit is approx 40mm x 25mm x 10mm.

Let me know if I missed any of the great questions!

Bill Parry

Bill Parry, could you please post more detailed specifications, here or on your web site?

Info I would like to know includes:
Minimum logging voltage
Voltage resolution
Voltage accuracy
Current resolution
Current accuracy
RPM resolution
RPM accuracy
Number of samples that can be recorded

Suprisingly this essential info doesn't seem to be available for any of your products. I am surprised that most modellers apparently are willing to buy a metrology device without any assurances of its quality.

Also on the MicroPower E-Logger page (http://www.eagletreesystems.com/MicroPower/micro.htm) the manual linked to is the Glide User Manual.pdf

TIA,

Neil.

[billpa]

All: your friend fly_boy99 has gotten you a free temp sensor with your Micropower order, this month! Just mention "RCGROUPS temp sensor special" in your order and we'll include one.

Larry, thanks for your order! We'll credit you for one of your temp sensors.

Neil: Sorry for the lack of specs on the Micropower, and for posting the wrong user manual. Our webmaster is going on vacation this week, so we had to get the unit up there immediately, even though the manual is not yet posted. The manual with the specs will be posted in a couple of days. Note that the specs on most of these are avaialble in the user manuals for the other products.

Here are some quick specs, sorry I don't have them all yet:

min volts - around 4.5v
voltage resolution - 0.1v
current resolution - 0.1a
RPM resolution - this varies with the RPM. the RPM goes up to 50k, but the "buckets' increase in size as RPM goes higher. I believe that the bucket for 50K is about 50 RPM, but I need to recalculate it.
RPM accuracy - see above
Number of samples - we use lossless data compression, so this depends on how rapidly the data are changing. If the data are changing slowly (like voltage) the # of voltage samples increases greatly.

Bill

[roccobro]

I see there are extra mags available, but how many mags are needed for the hall sensor to operate to the 50k limit? I go beyond 50K in alot of my stuff, would halving he amount of mags used cut the rpm in half for that application (i.e. 70k would read 35k)?

Thanks,
Justin

[billpa]

Hi Roccobro,

One magnet should work fine in this scenario. However, if it does not, we can make a firmware tweak to make it work (downloadable, thank goodness).

Bill

[roccobro]

Sweet!

Justin

[Neil Stainton]

Hi Bill,

Thank you for your reply. I understand that accuracy is hard to pin down, but can you give some sort of minimum accuracy figure?

Also regarding the number of samples question, can you say something like "Typically the MicroPower can hold x minutes data at y samples per second, when sampling just current and voltage"?

Regards,

Neil.

I want to know temps - but thats just me. I plan to monitor motor and battery temps.

I can guestimate (full throttle) RPM close enough - for my purposes - based on voltage changes.

Over temps are what can kill motors and batts.

Thank you all for you kind support. We're pleased to announce that this puppy is shipping, starting either tomorrow or Friday!

gapagod: thanks for the order! we actually do take paypal: sales@eagletreesystems.com. :-)

All, please don't hesitate to email me any and all feedback about the MicroPower unit. Since the unit has app updatable firmware, we can change just about anything as needed to provide a near-perfect experience, with the features that you need.

Our rc-groups special is in effect on orders received until the end of the month, but our shipping dept. will close on Monday the 19th, until the first week of Jan. So, we need to get orders in by Sunday PM to be able ship them for Christmas.

Also, here's a pretty darn cool video of the logger in action, brilliantly video mixed by Gary Goodrum at TPPacks.com:

Also, Manual and/or Fliers should give the length of the wires on the model with wire leads. Would also like to see Length, Width, Height of unit along with the weight.

Gapagod: we'll get that added! We've been meaning to do it forever.
Gus: thanks forthe info on the manual. I have made the changes and updated the specs. here are the complete specs:

MicroPower Specifications

Voltage Measurement: approx 5V to 45V
Voltage Resolution: 0.1V
Current Measurement: up to 100 Amps
Current Resolution: 0.1 Amp
Current Draw: approx 35 mA
Weight: Unit with Integrated Connectors: approx 0.5 oz (17 grams), Unit with Wire Leads: 0.7 oz (21 grams)
Temperature: Dual inputs, 0 degrees F to 424 degrees F (one temperature input when RPM is used)
RPM range: approx 100 RPM to 50,000+ RPM
Units of Measure supported: English and Metric
Measurements: approx 2.25” x 1” x 0.5” (57mm x 28mm x 13mm) including sensor pins
Length of Wires with Wire Lead Version: 2.5” (65mm)
Record Time: Varies with sample rate, parameters being recorded, and “activeness” of the model. Anywhere from around 20 minutes to hours is attainable depending on these settings. Since we use lossless data compression, it is not possible to give a precise record time.

Hot Dang!!!

Look what I got!!!

I love it Bill thanks for the great offer... I don't know which airframe to start with but there are plenty to investigate!!!

I was thinking about on-board deans plugs... Is that board really thick and strong? While its nice and clean way + no extra wire voltage loss but Deans plugs would apply some substantial loads to the device board/structure during connection/disconnection.

[fly_boy99]

What I can tell you is the board is built rock solid. At first I had misgivings about having a Deans on board and almost opted for just the wire leads out. But now after seeing it I'm glad I got it with the deans...

Time for some recordin!!!

Got mine a few days ago. I have done several bench runs so far.

I've been working with Bill on some calibration issues, but I am very pleased with the product.

I must say the dedication to customer service these guys have shown so far is absolutely outstanding.

They are going to add a "calibration" routine so that, if you want (as i do), the unit can be adjusted to agree with what ever your personal equipment of choice happens to be.

More later. Infact I will start a new thread in - hmmmm - power systems? or battery?

Just ordered mine tonight :). I put in a note for that temp sensor too :). My application will be in a RC car, so we'll see how it does!

Ordered the E-logger today. I did the paypal to 'sales' from my account as I can't see a "PAYPAL" button on the check out yet.

The first job for the logger when it arrives is a project Katana 40 EP a friend is putting together here. It's a reasonably high power setup so will provide some results about the logger in the 40-60 Amps range and on 5S voltage (20ish).

I'll drop in some results and graphs when I have the logger.

Ordered mine on 15 Dec and had it in hand on 28 Dec - not bad considering the time of year.

Did not have time to play and I am now back at work :( so I will have to wait a week or so till I can get it into the air. It is small enough to go on the indoor stuff so I should have some fun with those as well.

I have removed the wires and added 3.5mm female bullets and use a range of patch cables to connect to what ever I am flying that day (deans, Mini Deans, BEC, Power Poles etc). This also allows me to hitch a ride on other peoples planes even if they don't use my connectors.

I have a similar set of adaptors too. I ordered the version with Deans (Ultra ?) plugs fitted, most of my adaptors are compatible.
Sad about your testing delay. I'll admit I'm lucky here in Adelaide, there are many huge parks nearby I can put up electric models as big as a 48" Zagi with no issues. I can test every night this time of year :-)

One thing Eagle Tree might need to know.
I made a casual inquiry with their dealer in Australia (on their dealer list), about when the E-logger would be available here over the counter and at what price. The feedback to me was more or less "forget it" in different words.
I think ETS may need to find a Aussie new distributor, one that's more tech savvy too perhaps.

I finally got to test my recorder today (in flight instead of on the bench) on two short flights. Forgot to bring the temp sensors!!

I still need to figure out a bunch of details, but here is a first look.

The left (first)half of the graph is a flight in my Jinx clone with 3S TP1320 prolites and twin Little Screemer motors with 8X4 GWS props.

The second half of the graph is in my Katana Mini running on 5S1P TP 1320 packs and a Hymax 2025 2700 in a Cobri gear box and a 13x4(?) prop.

The first hi "peak" or spike on each graph is a short, full power motor runup just before take off.

This is way cool!

Got mine about a week ago and finally got a chance to test it out with some ships.

EdgeRC Devastator: Rocket 3600, TP2100 3S2P, CC25.
TREX Heli: Justgofly 450TH, TP2100 3S1P, CC35.

The Devastator was pulling 29 amps at times, causing shutdown, and the Trex maxed at about 22 amps. However, on full power climb outs, the battery did occasionally blip down to 8.9V.

Conclusions:
1) Time to switch the speed controls.

2) Start adding prop to the Devastor to get the speed up.

3) On the CC25 for the TREX, set the lipo shutoff to 8.8V (also saw this recommended somewhere else).

Gives a great warm fuzzy feeling knowing how many amps, watts, volts, etc I'm pulling. Thanks soooooo much!

You owe me a kickback on the Paypal info. I had to give a long dissertation to my wife espousing the benefits of this critical piece of flight equipment...just because the site didn't have the Paypal option. :rolleyes:

I finally got around to starting a thread in power systems.

Got my E-logger in the mail today. About 14 days or so after I paid for it. Not bad for USPS to Australia, some things have taken 21 days or so.

Checked out the unit on my test bench briefly.

Voltage and current calibration is good, about 0.1 units on both over 5 to 20V and 0 to 10 amps. Tested against my Fluke 83 DVM (which has been cal checked recently). Very pleased.

Temperature sensor works well and seems to be fairly rugged, it's a NTC type I think.

Software loaded fine, runs fine, looks very useful, lots of custom control. Talks to the logger seamlessly as it should.

All good here in OZ
Now to put it to work.......

I was able to test my E-Logger the other day in a edf. I bought the version with wires, removed them and added Deans Micros - now weighs ~13 grams. Very cool, I love this thing...

I've been regularly using my e-logger too. It's been very useful. The hardware is rock solid, the viewing software is catching up slowly.

One thing I've noticed, on my models the 'unloading in flight' theory is not reality. They seem to use the same peak currents I see in static tests and perhaps some even higher. Most are 3D types though, interesting.

Dear Bill,

I want to know, if i want to temp the motor and battery at the same time/ same flight. Is i need to buy two bag of temp sensor or just only buy one bag of temp sensor?

[TheLost]

Has anybody used the 'Optical RPM Sensor for MicroPower'? Im wondering if that would be easier to use then the magnetic one.

Just bought the E-logger... got the nerdy-gadget-giggles.

They were just announced yesterday......

Have one on order, and since EagleTree is in the same metro area as I am, I expect to try it very soon. Take a look at the instructions sheet linked to from the description to see how it mounts and such. It should be some easier.

Hi All,

I wanted to let you know that version 3.43 is "officially" released, which has most of the features that have been requested over the past few weeks (more to come soon):
