Re: SOLVED: Anyone done 3 B+ Stretch Wireless Access Point (WAP) successfully?

So what does happen if you do it per the Pi guide?

I have AP to Ethernet bridge working on the 3 B+!!! The trick is that you CANNOT do it off the bat on boot. You WILL get a kernel panic if you try, and your system will take forever to boot. It turns out you have to bring the two adapters up and let them settle first before you can slap a So, first,...

I've tried searching around and getting old parts... so I'd throw this out to the aether and see what comes out. Has anyone tried attaching a USB Gadget-ed Pi Zero to an iPad and been able to talk to it (say, Ethernet)? I'm looking at a 6 hour-ish flight across the USA, and I want to work on my long...

Using FFMPEG w/CRF. Will GStream w/hwencode support it?

I have a lot of Raspberry Pi's lying around, and a ton of MPEG4 and H264 video to transcode. Why not press them into service?

Would a 1 inch by 1 inch square of black electrical tape over U16 also work around this issue? I would assume the overlap would minimize any "signal" getting into the sides of U16.

Re: Extra SD card HAT?

Well, actually, if we're doing 4-bit SD on the regular card, we already have the driver -- it's in the kernel. I mucked with that on an old white BeagleBone. The caveat is that we'd need two GPIO's for a card detect and write protect (the latter I think we can get away with). I'd have to research th...

Extra SD card HAT?

I noticed that the 40-pin connector breaks out some of the secondary SD-card controller pins, so a second SD card can be put in. I probably can assume we'll need a GPIO to detect card insertion and the write-protect signal. So, with a spare 24LC256 and a old Sparkfun SD break-out board , I can proto...

Re: External SD card module

Are you connecting the CE0 AND CE1 lines together? Hopefully you are not, and putting one on one, the other on the other.

That said, I'm rechecking it on my origional Model B, making sure I have the wiring correct, before trying to find out what's going on in the kernel.
