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!


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.

Building a Swarm of Autonomous Ocean Boats — Hackaday

There’s a gritty feel to the Hackerboat project. It doesn’t have slick and polished marketing, people lined up with bags of money to get in on the ground floor, or a flashy name (which I’ll get to in a bit). What it does have is a dedicated team of hackers who are building prototypes to solve…

BeagleLogic turns BeagleBone into Logic Anaylzer

mobilewill was looking for a logic analyzer and found this BeagleBone-based solutions:


Quest for a Logic Analzyer

The BeagleLogic is a logic analyzer based on the Beaglebone created by Kumar Abhishek, a semi-finalist of the Hackaday Prize Best Product 2015.

The BeagleLogic features:

  • 100MSPS
  • 14 Channels
  • Web Interface
What makes the BeagleLogic special is it uses the BeagleBone PRUs which are basically 200Mhz microcontrollers attached to the ARM CPU with shared memory. This is one thing that sets the BeagleBone apart from other SBCs.

The cape is shared on OSH Park:

Tiny Tiny RGB LED Displays — Hackaday contributor extraordinaire [al1] has been playing around with small LEDs a lot lately, which inevitably leads to playing around with large groups of small LEDs. Matrixes of tiny RGB LEDs, to be precise. Where’s the LED?First, he took 128 0404 SMD RGB LEDs (yes, 40 thousandths of an inch on each side) and crammed them…
