DIP Protoboard for C.H.I.P.

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”):

DIP Protoboard for C.H.I.P.

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.

Retro watch with Bubble display

16 - 1 (3)Rafael Riber created a retro watch with HP QDSP-6064 Bubble display like 1970’s HP calculators:

RetroWatch

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.

Omniwheel Robot Laser Tag

Dan Fisher created this Atmel ATMEGA328P-based controller board to mash-up laser tag and battle bots:

Battlebots – laser tag style!

omniclose1

This is my version of a control board for this project from Make Magazine. It uses dual H-bridges ICs (SN754410) to drive each motor (channels are doubled for up to 2A continuous current per motor, 4A peak for very short times). Power LED. Also 8 LEDs run by a 74LS595 shift register for “blinky” fun! Photoresistor allows for a laser hit to be detected and affect the omnibot.
