    Apologies for video quality - I recently wiped my phone and have forgotten to reset the OpenCamera settings.

  • I bought a cheap "Ultrasonic" jewellery cleaner for cleaning PCBs. I wonder how ultrasonic it really is?

  • After being asked if I can measure the resistance of a cable and prove it shows a voltage drop I decided to do just that, in a number of different ways. Also shows you how to do a 4-wire measurement with normal DMMs.

  • How important is it to choose the right charger cable for your mobile phone or tablet? I take a look at a few cables I have here and the effect different currents have on the voltage your device would actually see while charging.

  • The SSD in my computer died the other day. Was I upset? Hell no! Now I get to rip it apart and see exactly what is in it!

  • Here's where I am at with both my new pulse rifle board and my fancy motion tracker board.

  • Quick test of the IR sensors of the Boxtec HelveKit32 robot.

  • A quick test of the Aliens Motion Tracker TFT Driver

  • Experimental Joystick Interface using the chipKIT Harmony USB integration.
