Toyota 4 Cylinder Engine 22RE (3D Print Template)

Working crank, pistons, and valve train. The valves open and close!!!. It may not be the most exciting engine but its the only one I had in my garage. Great

UPS Multiplug Hack

With all the power cuts recently thanks to Eskom and their “Load Shedding” I decided to re-use my old APC UPS to power something other than my computer and monitor. With the Multiplug plug hack I connected the conventional “Kettle” plug cable to an ordinary household 220v multiplug adapter. So far I was able to power my Telkom ADSL router, 8 port switch, PlayStation 3 and even a hair clipper.   !!!WARNING!!!

PS3 Controller L2 & R2 Trigger Fix

So after years of good gaming the R2 Trigger button on my Dualshock 3 PS3 controller decided to give in. The button was no longer springing back and as a result once pressed the button would stay engaged making contact and basically making the controller useless, so I decided to open up the controller and found that the coiled up spring had broke.  With no money to buy a new

The Radio Microphone

Radio microphones are used extensively by stage performers and professional eavesdroppers (Spies) but they can also be used for other fun projects such as monitoring of sounds. For example you can take an ordinary household portable radio and tune it to your desired FM frequency, then tune the microphone to the same frequency and place the microphone in a location around the home such as in your new born baby’s
