It’s been about 2 weeks now since successfully setting up the stm32f103 toolchain on my mac. Darn that was hard. Anyhow, I wanted to play around with telemetry for the Frsky receivers since ER9X supports it. I do have a hub, but one thing that bothered me was that to get the telemetry, we would be buying and installing a bunch of sensors that our main flight controllers already have. With this in mind I set about to seeing how…
I hadn’t gotten around to modifying the internals of my TX so I figured I’d have a go at reflashing the Hobby King 20A (F-20A) ESCs first. I chose this ESC because: They were really cheap They supported reflashing with SimonK’s firmware They had their test pads in a row so it would be easier All it’s FETs were the same (N-Channel) Some wiring had to be done to match the pin-outs from my 10 pin AVR programmer to the…
Here is a walk through on how I installed the Turnigy 9x LED backlight kit from hobbyking.com. You get a foam backing and the actual backlight panel that has a wiring harness attached to it. As my old soldering iron is fried, and all I have my butane field iron, I am only going to do the plug and play install for now. I don’t really want to use the field iron to solder things to the TX’s logic board…
Two boxes arrived today. Both much anticipated from hobbyking.com. The box hold the Turnigy 9x that I’ve bben waiting for. This TX sells so well that it is perpetually on back-order, and the do not allow placing pre-orders on it. Basically you subscribe to their email notification and when you get it, you rush to their site and place your order for it. Normally it sells out within half an hour of the email notification so you have to act…
Woo Hoo! I just received another parcel! It’s the motors that I ordered on aliexpress.com. These are A2212-930KV Brushless Outrunners and they cost me USD38 shipped. I don’t think you can find a better deal elsewhere. If you do, please drop me a note… lolz… They came in one of those bubbled envelopes, and they were wrapped in a lot of bubble wrap. On top of that they were individually packed into pretty rigid plastic so everything was very well…
More stuff has come in. This time from sunsky-online.com. I’ve had good experience with them and I find them much more reliable than GLB, cheaper too. The 2 main things here are the power distribution board and a bluetooth module. The power distribution board costs USD0.86 plus shipping. You can’t really beat that. As you can see, it can handle up to 8 segments. The quality of the board is nice and it had nice big pads to attach your…
The first part is finally here! I put in an order for a SK450 frame on aliexpress.com. When I ordered this, hobbyking.com had not started to carry it yet, but now they do so you can get it there. I was lucky and picked it up at aliexpress.com for USD26 including shipping so I don’t think I paid much more than buying from hobbyking.com (They sell it for USD17 before shipping). It comes packed in a small box that got…
