Case for Velleman Pocket VU Meter Kit MK115

thingiverse

This is a case for the Velleman Pocket VU Meter Kit MK115 (http://www.velleman.co.uk/contents/en-uk/p41.html). To make use of it, two modifications are required. First, the LEDs must be soldered at a height of 12mm from the PCB, not flush as in the kit photos/instructions. Secondly, one of the copper tracks on the PCB from the battery terminal must be cut through to allow for the addition of a push switch in series with the battery. This is optional but recommended as without this switch, the battery will drain continuously. Simply solder the switch wires across the cut made. A small momentary push switch from RS was used, which had a 6mm threaded shank to fit through the hole in the case and was also compact enough not to interfere with internal components. A version of the case without the switch hole is included for those who do not wish to install the switch. The lid screws are No4 Self-Tapping screws, which need to be screwed in gently to avoid cracking the plastic as they cut their own thread. The trimmer shaft protrudes through the lid only slightly and will require adjustment with long-nose pliers or tweezers from time to time.
