Roofing experts recommend inspecting your roof twice a year. One of those times should be just before winter to make sure your roof is ready for harsh winter weather. The other time is just after winter has passed to asses any damage that might have occurred. This latter inspection is often overlooked. Because winter is the most likely time for your roof to become damaged, itís crucial that you find and fix any damage as soon as possible before it gets worse. When the spring rains come, any pre-existing roofing problems are going to get a lot worse. Here are some tips for where to look and what to look for when conducting a roof inspection.

On the roof

Obvious signs of roof damage can usually be seen from the ground, especially if youíre using a good pair of binoculars. Some parts of your roof may be visible from a second story if you have one. You should be able to see if there are any missing, cracked, or curling shingles without getting up on your roof. If your shingles are showing obvious signs of wear, it may be time to replace your roof. At the very least, a professional roofer will need to come out and replace the affected shingles. Some signs of roof damage are less noticeable to the untrained eye. For best results, have a roofer conduct a thorough inspection to look for less obvious signs of damage such as problems with your flashing.

In the rain gutters

The rain gutters are another important place to look. When your roof is nearing the end of its...Continue Reading

Playing 4k video in Linux is a big deal. The days of software playback are decidedly over. The XVMC interface was the 1st method of hardware decoding. In 2007, it was replaced by the VAAPI interface in Intel cards & VDPAU interface in NVidia cards. Support varies from card to card.

Integrating hardware decoding in an editing program requires intimately dissecting each codec, replacing the specific functions the card supports with hardware calls. The mane codecs to support would be H.264 & JPEG. It's still in the realm of purpose built demos, nothing that could reach a wide user base.

Suppose you had hardware decoding in an editing program. What would you watch in 4k? The format most often viewed is still 640x360. Only rarely is it ever worth downloading something in 720p. The bandwidth to download 720p is now $110/month & rising daily.

The old timers were on to something when they designed the 1st TV resolution, in the 1930's. Motion blur & compression artifacts make most scenes look like 640x360.

It's a lot different than the serious cinema going days of 1999. Most movies are watched on phone screens, in a window, 15 minutes at a time. No-one shuts down for 2 hours to do nothing in front of a big screen, except for single women. They're always shut down.

4k is useful for archives. Probably in the next 10 years, everything is going to start as 4k. Today's 1920x1440 starting footage is still reduced to 1280x720 to make stabilization...Continue Reading

It took about two years of off and on work, but Topflite AT-6 is finally finished. All I need is some stick time on my other birds and a perfect spring day and I will be flying. The plane has retracts and flaps, and is powered by a new OS 91 surpass four stroke engine. Weight is around 11 pounds and it is balanced nose heavy to avoid tip stalls on takeoff. Below are some pictures.

Description:
FPV is the fastest growing segment of the RC hobby, and more companies are developing RTF FPV systems. WLToys, famous for their inexpensive, and very popular quads, is getting in on the action with their own FPV setups. The v666 is one such offering, and looks like it could be my first review of the 2015 flying season! GearBest currently has this one for sale HERE. If you stop by over there, and decide to drop one in your cart, add coupon code V666XH to get an additional discount. Check it out, and check back for updates.

This video was shot of my buddy Shawn flying his second attempt at owning a Parkzone Icon A5. This time is a Full-Sized version. The first attempt was with the Parkzone Ultra Micro Icon A5 Float Plane.

A reallly good and tought plane...a good air mule like the real one
one year of testing:
more than 4 flights each weekends
more than 40hrs of flight (averange 20min per 1600mah battery )
more than 400 take off and landings (some really hard)
more than 10 heavy crash...including nose crash, flap spin earth encounter and tip to the ground...

same wing
same rudder
same elevator
same fusselage
4 nose rapair (from LG line to motor, 3 panels+ firewall)
base of Landing gear glued 3 times
control horns glued 3 times
4 rebuilded nose cover
lot of hot glueand tape...

and some paint from my little daughter!!!

Horizon mode can be a lot of fun!

But… have you ever noticed that if you try to push forward at a significant angle, Horizon mode becomes unstable and almost uncontrollable?

One moment it is angled forward nicely, but with just a tiny bit more forward stick, it starts to pitch quickly forward into the dirt. If you pull back just a little, it then lifts up more than you'd like? It becomes very difficult to fly forward at high angles, or do steeply angled horizontal circles, for example. It just becomes too unstable.

This high-stick-angle instability is inherent in the current MultiWii 2.4 implementation of Horizon mode code, and it's been like this for some time.

This is why. When the stick angle gets to the point that Acro behaviour dominates the levelling tendency, the quad starts to pitch at ever increasing angles, forcing you to pull back. With typical rate settings for flips, the instability makes it very difficult to fly.

The code changes I’ve made seem to make things much better. The new code includes both the angle of the quad itself and he angle of the sticks - both work together to smoothly reduce the levelling. This has a number of benefits. The transition to acro is smoother and starts sooner (at lower stick angles). At higher stick angles, the quad flies smoothly and with greater control. At very high angles, even past or over vertical, up to nearly fully inverted, control is retained with that classic Horizon feel. You can do...Continue Reading

Apr 1, 2015 Freewing F-86 Sabre 80mm Flights 1 and 2

Both flights used the Admiral 4000mah 6S battery, pushed all the way back to the foam barrier. The plane was balanced to hit the 200mm COG, verified upside down with gear extended and also with the tail tip test. I did add a very small weight to the tail (a spare rare earth magnet from another plane).

The first flight took off with partial flaps (abt 30 degrees). I ran her long down the runway and was at full throttle when I rotated. In the video you can see the plane do a bounce about 3/4 into the take-off run. I think the nose gear hit a rut in the runway, the nose bounced up and she tried to get airborne on her own. I let the nose come down again and finished the acceleration and then rotated. The first flight was stable, but I had main wing oscillation from the gyro. (Man, she sounds sooooo good!). After one pass I brought her back down but with only partial flaps. She landed fairly smoothly despite the noob flying, but I needed the whole runway on the landing

The second flight I took off with lower gyro gain and partial flaps. The take-off was smoother and the oscillation was gone. Most of the flight was half to 2/3 throttle. The timer was set for 3:30. The landing was done with my full flap setting (still only about 55 degrees). It was shorter and smoother with the extra flaps. (Need lots of practice. The battery had 14% left in it after the taxi back to the pit.

All in all I'm a happy camper. This is my first...Continue Reading

Unzip the attached file to get the .apk to sideload onto your android device. When you install it will show a complete set of warnings however the application does none of the activities and does not access anything on your phone except storage. It's been constructed with MIT's App Inventor software. I take no responsibility and will not be liable for anything bad happening to your batteries as a result of using or misusing this application.
