After 12 desperate years, we finally have a cheap, miniature way to bridge a USB host to Wifi & bluetooth. All those gadgets which only provide a USB device controller for I/O can now be wireless.
Unlike the previous pi's, it really can function in the given form factor instead of requiring a bag full of peripherals. They finally fixed the problem of having to desolder 40 pins to access the GPIO header or having to desolder a bunch of headers to gain access to the USB & power signals. Wires can be soldered directly to large test pads on the back.


The heart of the beast is the BCM4343X, now sold as the CYW4343X. It's a bare die & a sign of how all chips are going to be packaged in the future. It provides all the wireless functions. The same chip is used on the raspberry PI 3B.


The bluetooth side of the BCM4343X is accessed by a UART. The kernel uses hciattach to attach the UART to the networking stack. Then, bluetoothd converts the socket interface into a d-bus interface. The python examples use the d-bus interface.


Current consumption is <300mA at 5V. Clockspeed is 700Mhz to 1Ghz. The kernel can be cross compiled, but all other C programs have to be compiled on the pi to satisfy dependencies. The mane program which needs to be compiled is bluetoothd. This takes 30 minutes & an 8GB flash card.


You must install the full raspian distribution, not the lite version to do anything useful. The 1st partition is a vfat boot partition. The 2nd...Continue Reading

Been building a flying wing ... And I didn't think I had a battery for it ..
Well I dug out a 2s 600mAh battery and thought - why not ? ( Was put away a long time ago )

So after some testing ( servos n stuff ) / setting up ..
I put it on the charger , plugging in the balance wire and pushing the go button the charger kicked up an error ..
Hmmmm .. So no balance charging ...

See the included picture and see if you can't spot a possible problems , besides the lose wires ... ( Clue )



Looking at the balance lead , the black and white wires look to be in the wrong place !
When I removed the wrapper , the wires just popped out lose ( ? whats with that )
So obviously there was a reason I had put this battery away !

I re soldered the wires ... ( for plug location rather than color )
I used one of my small battery monitors / alarms to check if all was good and it was ...

Should balance charge now .. Also allow me to run a battery monitor alarm



Lesson for the day , should most likely have unwrapped this battery when first encountered a problem ..
If there was a lose wire in there ???? Stuff could happen ...

I got this used but in excellent shape.
MKS 6100's all around on a 4 cell AA Eneloop pack with Spektrum "Carbon Fuselage" receiver.
I was going to switch to a Hitec rec'r but it doesn't really fit anywhere so the project stalled until recently when I bit the bullet and bought a Gen 2 DX8 radio.
Programming and channel setup is odd but I'm getting there.

I've been playing with the Syma x8c for a few months and have found it to be an excellent entry level quad. The stock camera is crap, but the lifting power is sufficient for a range of better action cameras. I've gone with the Runcam2 HD specifically for the FPV functionality. When paired with a lightweight VTX I've gotten a complete FPV setup for < $200!

-Syma x8c w/ transmitter $60
-Runcam2 HD $55
-Eachine VTX03 $13
-Eachine EV800 $55
-battery for VTX $5

I've found that when flying to capture higher quality video (my cheap-o version of of cinematic) that the FPV setup is not conducive. But flying FPV also makes for some fun videos when I fly this thing like I don't care if I crash it. Because I don't, because it was so damn cheap!

Except for one blizzard, it really was a mild winter for flying here in NE PA USA. I've been getting out once or twice a week steadily, but not at the club field because it is not maintained over the winter and tends to get swampy. I've been limited to parks. There are 3 close by that are perfect for UMX and park flyers, but the big guys have been in storage. The ground was still a little soft Wednesday, but good enough to walk on without getting water in your shoes or even sinking down. I was so excited to fly that I even forgot to take video. I just grabbed one image. In that image is Bob S. from RCG and Bob S. Sr. There is at least 70 years of flying experience there. If you click on the pic and keep clicking until you are fully zoomed in, you can see them flying the The HobbyKing Edge 540T EPP/Light Plywood 3D Aerobatic Airplane 1430 mm they put together over the winter. It is a beautiful plane and with their set up they can do some really spectacular flying. Maybe I'll get video next time.
