2017-01-12: Bitraf - build night - I didn't find time to work on this project, too many other interesting things happening. Time well spent!
2016-10-27: Bitraf build night again. Yes, a voltage divider is needed. I got distracted for the rest of the night, so no more progress on this project.
2016-10-06: build night at Bitraf again. Researching ways to connect the 433 MHz receiver safely to the Pi. The receiver is designed for 5 V VCC. Do I need a voltage divider?
2016-09-29: serial console - I'm using a cable that looks like the Adafruit 4 pin cable (it can be), and green is RX, white is TX and black is GND on the cable. From my Fedora laptop:
[tingo@localhost ~]$ screen /dev/ttyUSB0 115200 [detached from 6674.pts-1.localhost]
2016-09-28: I have 2 x 149252 433 MHz receiver and 2 x 149254 433 MHz transmitter from DX.
2016-02-18: Bitraf build night - I tested the microSD card in the Pi B+. It took a while to resize the ufs partition on first boot, but other than that it works nicely. I only connected keyboard, power, mouse - no network, so no info from the testing.
2016-02-18: Bitraf build night. I forgot a HDMI cable, but have the rest. Downloaded a FreeBSD 10.3-beta2 image for the RPI, and wrote it to a 32 GB Kingston microSD card using my Fedora laptop.

wow, fast.write. disktype says:

2016-02-13: Tried to fit the cases tonight. The pins in the bottom half are a bit big (I can't get the top on, and I can't get the Pi onto them. I used a small tool to wear off a bit of plastic, but still some pins broke, both from removing the lid, and from removing the Pi. One of the cases survived, so I used rubber bands to keep to lid on.
2016-02-11: at Bitraf build night, I printed two cases (Adrien12's Raspberry Pi case (model B+ / 2) very nice), after fixing the printer and my Cura settings (the printers have a 0.4mm hotend, not 0.3mm).
