How to Make LJBot 0.5, a 3D Printed Raspberry Pi Robot #piday #raspberrypi @Raspberry_Pi

NewImage

Great project from jacksonliam on Hackaday.io:

A robot designed to house the Raspberry Pi Model A+ or Zero, two 28BYJ-48 Stepper Motors with ULN2003 Drivers and a hr-sc04 or hy-srf05 ultrasonic distance sensor (srf05 recommended).
Optionally the steppers and drivers can be replaced by a micro gear motor and dual h-bridge driver.

Its powered by a cheap USB power bank (the ones that hold a single 18650 battery) that sits on top.

Aside from that the only thing you will will need is 4x m3 bolts/nuts to secure the steppers and 10x dupoint cable to hook it all up.

With the zero, there’s plenty of room inside for other modules, like a compass.

The ring on the lid is sized to optionally have a neopixel ring taped under it!
