![]() ![]() In positioning the Pi I have also taken care to leave a good gap round all sides that have ports so that I could plug in cables if I need to for troubleshooting issues with the Pi. The block of wood is fixed to the case using glue-gun glue. Raised up the Pi a couple of centimetres gives me enough clearance to get a figure underneath and coax out the memory card. I have done this so that in the future I can easily remove the memory card if I need to. I have removed the top portion of the plastic case and have used a screw hole that was manufactured into the case to fix the Pi to a small block of wood. At the time I bought it I also purchased a clear plastic case. The Pi I'm using is a Raspberry Pi 3 Model B Rev 1.2 that I've had for a while. So I used a terminal block and some extra mains wire (with the outer plastic casing removed) to bridge the gap between the mains cable and the transformer. They weren't held on particularly securely being my first attempts with the crimping tool. In feeding my crimped mains cable through the whole the crimp connectors came off. You can now also drill a hole for the mains cable. I made sure to leave as much room around the terminal connections as possible. With the pegs removed I fixed the transformed to the case using glue-gun glue. I have since learned that they can also be removed using a very sharp paid of wire cutters. You can remove the plastic pegs by using a multitool like I did, but you may leave behind scuff marks like I have. I've removed all of these apart from the ones by the top middle and bottom middle screw which don't get in the way. Annoyingly the box has some plastic pegs which can get in the way. The next step is to fix the transformer in the box. Step 2: Fix the transformer inside the case Initially mine was reading around ~4.5V, so using a screw driver I turned the orange screw between the screw terminals and the power indicator LED clockwise until I was getting an output of 5V. The next step is to use a multimeter on DC output terminal screws (two right-most screws) to check the DC voltage. Close up of the terminal block showing the orange adjustment screw to the left of the power LED If everything is wired up correctly the green LED should turn on. One the spade connectors are fitted to the screw terminals and you are happy with the wiring, it is time to plug in the transformer and see if it works. ![]()
