Case for Velleman Pocket VU Meter Kit MK115


Summary This is a case for theVelleman Pocket VU Meter Kit MK115 ( To make use of it, you need to slightly modify the kit in two ways. (1) You need to solder the LEDs at a height of 12mm from the PCB (not flush as in the kit photos/instructions). (2) Cut through one of the copper tracks on the PCB from the battery terminal so that a push switch can be added in series with the battery. This is optional but recommended as without this switch, the battery will be draining all of the time. Just solder the switch wires across the cut that you make. I used a small momentary push switch from RS that had a 6mm threaded shank to fit through the hole in the case. It was also small enough not to foul against any Internal components. I have included a version of the case without the switch hole for anyone who does not want to fit the switch. The lid screws are just No4 Self-Tapping screws. These need to be screwed in very gently to avoid cracking the plastic as they cut their own thread. The trimmer shaft protrudes through the lid only slightly so will need to be adjusted with long-nose pliers or tweezers. It should not need adjusting very often.
