For the motor contorller (quad half-h driver) I notice in the shipping kit and in the published schematic, you use the L293D, but in the parts list you mention the SN754410NE. Why did you switch? Was there a problem with the SN754410NE?Thanks,--…

I'm having a problem where it is very flaky about detecting RC mode.There are cases where no receiver is connected and it goes into RC mode, and cases where there *is* a receiver connected and it doesn't. It seems to be almost random about whether…

Mitch Patenaude commented on Chris Anderson's blog post Instructions for using BlimpDuino
"I have a problem where it isn't consistently recognizing RC mode. The code looks to be averaging "channel 1" position, but it seems to be an int timer which counts clock interupts, and since the running average only has to get to 1, it should detect…"

After being unable to find them on the web or in the local hobby shops, I'm trying to make the female to female patch cables used to hook the radio receiver up to the board, and I'm a little confused, and probably out of my depth.I ordered some…

"I'm thinking that using 4 of these sensors rather than the ir detectors would make for some interesting behavior. I would probably need to tweak the code for the slower readout rate."

"I would love to see a youtube video of how you work with that foam. Do you use a hot-wire cutter, or just a regular knife? How much tape do you use to strengthen the foam?"

"I hope you'll excuse all the questions. I'm somewhat new at this. The 300mAh 2S lipoly packs I can find in local hobby stores aren't balanced, but I'm not sure how much difference it really makes.

Should I hold out for the online pack and charger,…"

"What about the voltage? Will the switching regulator on the board handle 11 or 14 volts? will the motor controller?"

"The pack you mention is on backorder everywhere I look. Would this battery be an acceptable substitute? it's slightly heavier (22g vs 19.5g for the other one) but otherwise has similar characteristics, though the form factor is somewhat different.…"

Mitch Patenaude commented on Chris Anderson's blog post Correct Blimpduino LED/motor/servo behavior
"Just to clarify, until the blimpduino code is loaded using the FTDI cable, the RC mode will not work with the code that is loaded at the "factory". Is that correct?"

Mitch Patenaude replied to Mitch Patenaude's discussion Recovering from making the motor wires too short?
"To answer my own question: No, 6 inches in not enough. Will 22 guage wire work, or is that to heavy/stiff. If I need the finer wire, what gauge is it, and is it available at Fry's/Radio Shack, or do I need to order it?

"What would happen if you tried to use this outdoors? I have carpeting in most of my house, and have been considering using this outside with it ballasted slightly negative, so that I'm sure it will come down."

It's been a while since I've built a kit, so I made several mistakes while building the kit, and I wan't to know if I've recovered from them okay.First, what is the best way ot strip the wire provided for the motors? I didn't have a stripper that…

The instructions say to cut a 6-pin male header for the ultrasonic sensor, but there it seems to need a 7 pin header (and 7 is what the picture shows.
