Teensy MIDI USB foot controller for controlling Mobius Looper

Thrifleganger wrote this instructable detailing his Teensy MIDI USB foot controller for controlling Mobius Looper: The concept is quite simple and straightforward. You press a button, the arduino interprets the signal arriving from the button as a midi “control change” signal (typically represented as MIDI CC), and this signal can be mapped to respond to any of […]

Workshop Organizer – inventory controller for home-workshops

Dilshan Jayakody writes: Workshop Organizer is light-weight, cross platform inventory controller for home-workshops. This application is specifically design to manage electronic/electrical components at home-workshops, but it can use to manage other areas of workshop including tools, machinery and mechanical components, etc. To store data, this application use SQLite database system and all the necessary runtime […]

OpenSprinkler, an open-source internet-based sprinkler / irrigation timer

Ray has written a detailed article about his OpenSprinkler 2.0 Arduino-based irrigation controller: OpenSprinkler is an open-source Internet / Ethernet sprinkler timer / controller based on the Arduino platform. It works with standard 24VAC sprinkler valves commonly found in household watering and irrigation systems. You may be planning to buy or have already purchased a commercial […]

Karma controller project

William built this Karma controller and wrote a detailed explanation on his blog describing the build: My latest project is the Karma Controller, which has seven buttons to control Reddit Enhancement Suite. I made two revisions. The second is custom etched (which looks super cool!). I’ll also be sending them off to a real PCB shop for […]

AVR microcontroller based PWM fan controllers

Zak Kemble posted his AVR based PWM fan controller build: So this is a bit of a continuation on my 555 timer based PWM controllers, but now using microcontrollers and MOSFETs instead of 555 ICs and transistors. I made 2 versions, one with switches for speeding up and down and the other with a potentiometer […]

PlayStation 2 controller Arduino library

Bill developed an Arduino library for PlayStation 2 controllers: I had to rewrite a lot of code that powers the library, there is not much left of the original code written by Shutter of Arduino forums. There were many bug fixes, now the controller should automatically be in analog mode, and the mode button should […]

TinyG G-code motor controller

TinyG is a multi-axis motor controller for DIY CNC machines. Most CNC controllers receive instructions from a PC, but the TinyG executes G-code directly. By running the Gcode interpreter directly on the chip it avoids the expense and problems of trying to precisely control step timing with a general purpose computer that has other things […]
