So I didn’t want to throw down several hundred dollars for a TxRx combo, so I went with the $99 solution. The Spektrum DX5e is a five channel, full range transmitter that comes bundled with the AR500 receiver. Since I am reading the PWM in parallel and not the PPM, I needed to determine the [...]
Haha, it flies! I had no idea what to expect for the first series of flight…at least nothing broke. Here is one of the indoor tests. I had the stability turned off for the yaw axis, and that’s why it spins around in the air like that. It’s kind of cool to see how necessary [...]
Well, for some reason I’m in Las Vegas attending MIX09. I’ve got bags full of swag and every other person in the Venetian has a laptop out (even while walking). I just attended the keynote, and it was awesome. It seems Microsoft has been pretty busy giving web developers some really powerful tools. First, Bill [...]
The replacement AR500 receiver came in the mail the other day. I managed to power it up without killing it like last time. I got a brand new transmitter too because the first one was the wrong mode. Mode 2 has the throttle on the left stick (which is standard in the US), and what [...]
Today was a very productive day for the quadcopter. I had already converted the 4000mAh beast to a Deans setup, so I had to get all of the ESCs and Arduino power cables to join the battery in parallel. I bought a very cool 1 male to 2 female Deans parallel connector at the hobby [...]
I’ve been meaning to post about this for a while now. I’ve successfully achieved super low latency audio on the iPhone. The app is using RemoteIO, which is a super-duper-under-documented audio unit. Much of my success is due to Mike, and his blog is here. It’s running at about 5 milliseconds latency right now to [...]
