CANPi: CAN Bus for Raspberry Pi


RasmusB created a CAN Bus adapter for the Raspberry Pi: CANPi

This is an electrically isolated CANBUS adapter for your Raspberry Pi. Even if you screw up the connections somehow, nothing will be damaged. It also fits within the normal Raspberry Pi footprint, meaning that you can use it with most enclosures.

The board was designed with KiCAD and the design files are on GitHub:



RasmusB has made the board a Shared Project on OSH Park:

2 layer board of 1.58×1.08 inches (40.16×27.46 mm).

NEDONAND Homebrew Computer

Alexander Shabarshin of NEDOCON has created the impressive NEDONAND homebrew computer:

NEDONAND is 8-bit homebrew computer entirely built out of many 74F00 chips (2-input NAND gates)

Alexander describes the details on

I started NEDONAND in order to achieve a few goals:

  •  use only 74F00 chips (2-5 ns delay per gate) to get maximum possible performance (at least 1 million instructions per second)
  • 8-bit data, but 4-bit ALU (similar to Z80) with carry/borrow and overflow flags (with approach similar to 6502 where borrow is inverted carry)
  • no microcode in ANY form, just 2-stage pipeline and RISC instruction set (similar to PIC – 4 ticks per cycle, 1 cycle per instruction)
  • open source (public domain hardware and copylefted software) and hobbyist friendly design (only through-hole components)
  • all parts will be well-documented and could be used as standalone addons in other projects
  • everything simulated in Logisim first (circuits are provided as a single nedonand.circ file)
  • plan to build PC-connected “testbed” to test different parts of the project separately
  • If you want to purchase NEDONAND boards (I share only tested ones): OSHPark/Shaos
  • Hardware files for Eagle v5.12 and gEDA (pcb): Eagle files, gEDA files (it may have some untested things).

In this video, Alexander shows part of the NEONAND program counter:

FeatherWing designs by Sync Channel

Dan Watson of the The Sync Channel Blog has been designing exciting FeatherWings (e.g. daughterboards) for the Adafruit Feather line of microcontroller development boards.  Dan wrote a nice introduction to Feather:


Helping Your Feathers Flock Together

“Occasionally I see a new product or microcontroller development board that really sparks my interest. That’s what happened with the Adafruit Feather line of boards. They pack a lot of punch into a small footprint, especially when you consider the fact that LiPo charging is built-in, as well as Wi-Fi, Bluetooth, or an SD card on some of the variants.”

Dan designed a FeatherWing that combines a GPS and 9DOF IMU sensor:


MultiNav FeatherWing for Adafruit Feather

“The MultiNav FeatherWing is an add-on board for Adafruit Feather. It incorporates a U-Blox NEO-6M GPS module as well as an InvenSense MPU-9250 9 Degrees of Freedom (9DOF) sensor.”
He also added the board as as OSH Park Shared Project:

Dan also designed a FeatherWing for low-power, long-range wireless communication:


LoRa FeatherWing Development Breakout

“LoRa is an ultra-long range wireless technology that uses sub-GHz ISM bands. It allows the interconnection of small, low-power sensor nodes and Internet of Things (IoT) devices. There are many LoRa transceiver modules on the market from manufacturers such as HopeRF and MicroChip.”

Apertus Open Source Cinema Camera

GEZ_2364 Better Sensor (1)We are very excited about Apertus and their mission to create an Open Source Cinema Camera:

The goal of the award winning apertus° project is to create free and open technology for todays professional cinema and film production landscape and make all the generated knowledge freely available.

And we love their philosophy:

Why Open Source?

The apertus° project is based on software free to be used for any purpose, free to be studied, examined, modified and redistributed – which includes distributing your modified versions. Hence, products and services developed by apertus° are almost exclusively released under GNU General Public License V3 . * Documentation provided is licensed under the Creative Commons License and the hardware under the Cern Open Hardware License .

Apertus ran a crowd-funding campaign in 2014 that raised €204,568:

Notice purple PCBs in the video?  We are very proud that Apertus has been using OSH Park to make boards since 2013!

OSH Park: Profile for apertus


Their GitHub organization contains software and hardware:

pi2vga: low cost VGA output for Pi Zero user mincepi wanted a VGA output on his Raspberry Pi Zero. His quest led him to design a PCB that mates with a VGA monitor and the Pi board and–according to his estimates–costs about $3.62 each (although to get that price, you have to build three).

mincepi has shared the board on OSH Park:

pi2vga: Pi Zero lowest cost VGA output

The vga666 by Gert is already a low cost VGA output option for the Pi. But we can do better with the Zero! First, we’ll use 16 bit output instead of 18 bit. This frees up the SPI and I2C ports with little loss in quality. The resistors can also be soldered between the Zero and the adapter, making the PCB smaller and eliminating a connector. I’ve also determined that 5% resistors are good enough: no need for higher cost 1% units. And by not using the middle row of pins in the HD15 connector, we can straddle-mount it on the PCB edge. The connector can be male, so the Zero will connect to the monitor ChromeCast style: no VGA cable needed. (This connector could even be scrounged from an old VGA monitor cable for free!)

Canon DSLR WiFi Remote with ESP8266

Guillermo Amaral shows how to make your own WiFi Canon DSLR Remote:

Having a tripod with you is not always all you need in order to take sharp, good looking pictures. Sometimes in low light conditions, your hand pressing down on the shutter trigger can make the image come out blurry.

So why not mix the power of the ESP8266 with a convenience of a shutter control? That way you could take photos while you’re chilling watching Netflix.

Make a PCB with Fritzing & OSH Park

Fritzing is an open source free downloadable PCB design tool for hobbyists that only allows you to design and export gerbers for two-layer boards. It runs on Linux, Windows, and Mac:

OSH Park Docs: Fritzing


Fritzing + OSH Park = PCB!


Pete Prodoehl of Milwuakee Makerspace and Maker Faire Milwuakee posted yesterday about his experience designing a Teensy LC breakout board with Fritzing and having it made by OSH Park:

I recently created my first “real” printed circuit board. By “real” I mean one that I sent out to get fabricated, not one I did at home by etching it myself. The board is for a Teensy LC, and breaks out most of the pins to screw terminals.

Once all the pieces are in place and connected up I switched to PCB view where you get to see what the actual printed circuit board will look like. […] It will output a whole bunch of files to the folder specified. Once I had this folder I made a ZIP file from it, and named it and uploaded it to OSH Park.
