Here's a picture of our DC-DC converters mounted inline on a cable. Not the prettiest of solutions, but works perfectly for voltages up to 36V without generating any heat

I read through the posts and didn't see anything about you making an adapter cable, so if the gps works on another system using it's default connector, I'd take a close look at the made adapter.   Anyway, good luck, hope this…

Can anyone/Would someone explain the "signal in, voltage in/signal out, voltage out on the example board listed by Mark?  I understand you'd need to connect a battery source to the board in order to get the 3,5,9,12 volt outputs, but…

@Anish, does this look like a reasonable design for the lm317?  I think I would want to replace the pot with a resistor of the appropriate value. http://www.ladyada.net/library/equipt/diypsupp.html

@mark wouldnt be suprised, its like a well known recipe for cooking. Tried tested cheap lm317 :)

@brian looks to me like a lm317 three pin voltage regulator chipset. as per specs it could support upto 1.5 a. The idea of mutliple outputs sounds interesting

Owen - Thanks for the help.  I'm sure that others have similar questions. This does seem like a very simple way to do it.  Does this work to power multiple devices (w/same power requirements) or is it for one device only?   With…

Yea it is as simple as you said. The very last section of the datasheet has a diagram showing the pins. The middle pin (2) is a common ground, pin 1 (the one with the dot above it) is the input voltage (5-36V) and pin 3 is the regulated output…

I have also found this power supply from sparkfun.  It also looks very promising. (link) This one has options for how power is connected and has an on/off plus dual voltage. This one is bigger than the other sparkfun unit but it is…

3.3v Power Supply Options - What's recommended?

Posted on January 22, 2012 at 1:00am 14 Comments

The items shown above are part of a 5.8GHz video transmitter (#5) setup offered by Range Video.  All items are sold as individual items and like a big dummy I forgot to get Santa Clause order their powersupply (#4) when she placed her order for the transmitter. 

So the luck of the Irish kicks in and Mr. Murphy ordered their last Filtered Linear Power Supply and there's no telling when they…

In Flight Motor Failure

Posted on May 1, 2011 at 10:14pm 0 Comments

So I finally got to do some testing without crazy winds, then THIS happens!

 

Oh well, it could have been very bad, but I was lucky and did not have any major issues.

 

I have some repairs to do, but in reality I was thinking of doing the mod I NEED to do now anyway, so... NBD!

Wireless RF Transceiver 431-470MHz - Good Enough for Learning?

Posted on April 7, 2011 at 10:56pm 17 Comments

Other than "you get what you paid for" Anyone have a reason Not to buy this pair? 

My personal goal would be to use it as a learning tool, prepairing for adding telemetry to my projects. But it should be usefull too.  Secondary use in some project around the house, ie halloween automation, laser guided water splasher (anti-cat crap in the yard device currently in planning…

My ArduPilot Trials Day 2



I started off the day very excited to see how a new day of testing would go. I'd re-read portions of the manual, searched for ArduPilot tuning posts and contemplated the replies I got from my…

I am really enjoying learning about electronics and applying that stuff to something I really love to do, fly my planes. I need to learn more!

But if Necessity is the mother of invention...

I NEED something that will help keep the neighborhood cats from crapping in my yard. Anyone out there worked with the ardino/boardinos on projects that involve ir sensors and watervalves?

Just uploaded some fun pics for my Tandem Wing project. Was hamming it up a little but was surprised to see how well it glided. After tweaking some I got it to not pitch up at landing but that's a fine line and is easy to add too much weight to the nose. I'll get some of the foam box flight tests pics posted as soon as my photographer starts working with nerds again... :/

I use a german shepherd and a labrador/coolie cross. They are low maintenance and good with children. Not good with cats!

wow, no i haven't modified the plane at all. in fact, it flies very well for me as is and i've seemed to only screw things up when i try to modify anything :). i'm concerned when you said that you had to cut away some foam to fit electronics. if i get the APM, will i need to modify a lot of the fuse? Also, i noticed you mentioned in a forum that you were having some control issues w your version of ardupilot bc the program was designed around the easystar and not the sf max. have you worked the bugs out? i'm waiting to make the investment into the ardupilot, but when i do, i plan to get the APM w IMU and telemetry (the whole 9). I already have a basic fpv system for the plane, but have yet to test it (really excited to try that too).
Let me know if you have any thoughts. It's great to hear about someone enjoying their SF max. I really love the plane.

yeah i'll have to take some shots of my plane too.  i'm thinking that i'll have to remove that top canopy/windscreen piece too and possibly move some things around to make space.  i will be testing this fpv system this weekend (hopefully, if the weather cooperates) and i'll probably order the ardupilot mega fully soldered w the software uploaded soon.  My only decision left is whether or not to add the $199 telemetry hardware with it.  i look fwd to seeing ur pics.

Thanks!
