Upgrade Jukebox lighting with Arduino & WS2812 Adresable led strip

I cleaned my Kotronic jukebox and now it’s time to give this an upgrade. I will leave all of the original electronics intact and still working but I will add the WS2812 led strip inside the bezels, top and centerpieces. these will be controlled using an Arduino to simulate the “bubbler” bezels from the original wurtzinger/rock-ola jukeboxes […]

DIY Simple Arduino Bluetooth controlled Robot

This is a detailed guide on how to build a Bluetooth controlled robot using an Arduino, the robot is controllable from any mobile device or laptop over Bluetooth, has lights, and a distance sensor to prevent it from crashing into the stuff. The Bluetooth can also be used to remotely program your Arduino and directly […]

DIY Automate your Football Table Score with Arduino

A complete guide on how to use an Arduino to automate your Foosball Table, including an automatic score counter on any mobile Phone, Tablet, PC or Laptop. Using an Arduino network shield we create a server that will be viewable on the Arduino’s IP. the score-counting will be handled by two lasers and light dependent resistors […]

Arduino Light Dependent Resistor(LDR) Guide

Arduino wiring diagram ldr

A Photoresistor or Light-Dependent Resistor (LDR) is a light-controlled variable resistor. The resistance of a Photoresistor decreases with increasing incident light intensity. This guide will connect the LDR with an Arduino.

DIY PC PSU to Bench / Project Power Supply

DIY PC PSU Bench Power supply voltages

Computer power supplies cost around US$30, but lab power supplies can run you $100 or more! By converting the cheap (free) ATX power supplies that can be found in any discarded computer, you can get a phenomenal lab power supply with huge current outputs, short-circuit protection, and reasonably tight voltage regulation on the +5V line.

Fix FTDI DMX interface & Arduino on OSX 10.9+ Mavericks

OS x FTDI Driver Control

Apple recently decided to make their own FTDI driver with the release of OSX 10.9 Mavericks. This broke compatibility with Arduino & USB DMX interfaces based on an FTDI chip. Here is how to disable the new driver and use the old FTDI driver. All your apps will be working again like they should.

Arduino Composite TV output Shield

Arduino AV out DIY shield

Shields are boards that can be plugged on top of the Arduino PCB extending its capabilities. The Arduino is also capable of sending out a video stream to your TV over a yellow component cable. So here is how I made my own Composite video-out for Arduino under 15 minutes.
