Smaller version of GameBoy Zero

moosepr designed this small and simple GameBoy-style device using the Raspberry Pi Zero:

I’m not overly fond of ‘rats nest’ wires, and I have a bit of an obsession with making things as small as possible, so this is what I came up with.

Tis just an ILI9341 screen, a Pi Zero, 2 navi switches (5 way), and a battery (with charge/protect circuit)

Raspberry Pi Zero W desk clock

Nick Sayer created a LED desk clock driven by NTP on a Raspberry Pi Zero W:

Raspberry Pi Zero W desk clock

When I was in college, I bought and built a Heathkit GC-1000 WWV clock. Since then, I’ve been somewhat interested in accurate time measurement. I recently designed a GPS driven clock, but sometimes your local WiFi reception is better than GPS (say, indoors). For those circumstances, a clock that gets time from NTP over WiFi would be preferable. The newly released Raspberry Pi Zero W makes this quite a bit simpler to achieve

IceZero FPGA Board for Raspberry Pi

Black Mesa Labs created this board that adds a Lattice FPGA to a Raspberry Pi:

IceZero FPGA Board for RaspPi

BML has been very much enchanted with the Lattice FPGA boards for Raspberry Pi, IcoBoard , BlackIce and IceHat. The IceZero board is a BML creation that attempts to combine the best features of all 3 boards into a single design.

IceZero features common with other designs

  • Fully Open-Source Hardware and Software Design.
  • Lattice ICE40HX4K FPGA that supports Clifford Wolf’s Project IceStorm tool chain.
  • Interfaces to Raspberry Pi 2×20 GPIO Header for both power and bus interfaces.
  • PROM programmable directly from Rasp Pi, no JTAG programmer required.
  • External SRAM, supporting soft CPU core designs ( code execution ).
  • Extra large SPI PROM, supporting soft CPU core designs ( code storage ).
  • Industry standard PMOD expansion headers

IceZero features that are BML specific

  • Mesa Bus Protocol 32 MHz SPI link between CPU and FPGA.
  • 2-Layer PCB design. Orderable via OSH-Park or Gerbers for Downloading.
  • FTDI 1×6 USB Serial Cable header for use with PC instead of Pi ( or as a soft CPU debug Trace Port ).
  • Single Pi UART plumbed to FPGA for muxing to multiple external serial devices.

Order from OSH Park

This board is part of Alan’s Raspberry Pi data collection system:

Mini-Monitor

The Mini-Monitor software is data acquisition software that runs on a Raspberry Pi computer. It is designed to post the collected data to the BMON web-based sensor reading database and analysis software, but the software can be modified to post to other Internet databases. The Mini-Monitor software has the ability to collect data from a number of different sources

Combo board for the Raspberry Pi with IR receiver and transmitter along with Real-Time Clock and coin cell battery:

Raspberry Pi IR receiver + IR transmitter + RTC

I needed an IR receiver for my Raspberry Pi which I use as an internet TV receiver [..]  Solution: make my own.
