A special stackup intended for a variety of high-power and low weight circuit designs. This service features a 0.032″ (0.8mm) thick PCB, and includes 2oz (2.8mil, 70um) copper. That’s half the thickness of our standard boards, and with twice the copper!
Half-height PCBs from OSHPark will allow us to measure mag fields in tight gaps.
modular-muse.com is the home page for this project. It is a large part of my PhD work at the ATLAS Institute. Modular-Muse is an instrument building platform that consists of hardware board and software library to explore new ways of creating musical instruments. The Sound Clippys Board is an Arduino based board that allows for simple circuits to […]

OSH Park engineer Jenner Hanni posted on Wickerbox Electronics about his Arduino Theremin project:
This is a sort of false theremin that turns the distance between your hand and the rangefinder into notes. There are three cap sense pads you can touch to change the key, and the program remembers your most recent song so you can choose to play it back.
The KiCad schematic and layout, along with the the Arduino code, have been released on Github under the CERN Open Hardware v1.2 License:
Jenner shared the board on OSH Park:
Dan Watson has designed a new FeatherWing that adds the MicroChip RN2483/RN2903 LoRaWAN module to Adafruit Feather:
Help your Feather fly into the IoT clouds with this awesome LoRaWAN module from MicroChip.
SyncChannelBlog has shared the board on OSH Park:
[Nick Sayer] can reflow, and he can prove it. He designed a simple blinking-LED circuit that uses SMD parts to, well, blink LEDs. That’s not the point, though. It’s designed to be a test platform for reflow soldering, and to use a minimum number of valuable parts. Plus, it says “I can reflow!” in exposed…

Nick Sayer created this GPS disciplined high precision oscillator to generate a very accurate 10 MHz square wave:
The basic design of the project centers around either a VCTCXO – a Voltage Controlled Temperature Compensated Crystal Oscillator or a VCOCXO – a Voltage Controlled Oven Controlled Crystal Oscillator.
Geppetto Electronics sells the module on Tindie:
A GPS disciplined 10 MHz frequency standard – ±1 ppb or ±0.1 ppb
[Rafael] made a sweet little retro watch that’s a fantastic introduction to hardware DIY. If you’ve programmed an Arduino before, but you’ve never had a board made, and you are up for some SMD soldering, this might be for you. It’s got some small components, so ease off the coffee before soldering, but it’s nothing…

Jeremy g. on hackaday.io created this tiny retro clock:
Super tiny, Micro clock using a Numitron as its display. Running off a 400mAh lipo battery.
has shared the design files and source code are on GithHub:
The assembled version is available on Tindie: NumiClock Mini
Electrical Engineer Jenner Hanni (of OSH Park and Wickerbox Electronics) designed a protoboard DIP for the Next Thing Co. C.H.I.P. (“The World’s First Nine Dollar Computer”):
for when you need something more durable than a breadboard
The KiCad schematic and layout are available at the Github repo. The project is released as Open Hardware under the CERN Open Hardware v1.2 License.
This project was created using the CHIP DIP KiCad template from Wickerlib. The protoboard holes are connected where indicated by exposed copper, for easier wire routing and soldering.

Bill of Materials
For a non-stackable version, you can just use two standard 0.1” (2.54mm) pitch 1×40 headers, each snapped in half.
For a stackable version, you can use two of these extra-tall 2×20 female headers from Adafruit. The connectors are from the Samtec SSQ family so you could shop around for other distributors, but Adafruit has by far the best price for this particular component.

Rafael Riber created a retro watch with HP QDSP-6064 Bubble display like 1970’s HP calculators:
The display is controlled by an Atmel ATMega328P-AU MCU with Arduino code, and the time is kept by a Maxim DS3231 Real-Time Clock module, that stays connected to the LiPo battery at all times, keeping time even when the microcontroller and display are not powered.
