TKB Build - 6 - The Touch Keys

The touch keyboard of the TKB is really really special. When I first saw one I was mesmerized. It reminded me of the stylophone that I owned as a child. The Serge TKB however, doesn't need a stylus.

If I understand this correctly the TKB uses the capacitance principle (not FSR - force sensing resistors).
where detection of the plate capacitance is important. Touch keyboards can be found in many instruments (both old & new). The stylophone, the EMS AKS, The PAiA drum & Buchla keyboards from the 60's to the present day are but a few examples.

This part of the build involves installing the LEDs

These are tiny surface mounted components. Becareful when installing as they are easy to loose.

Mount as flat as you can & be careful of the orientation. The cathode is to the right.

Part 7. Front panel assembly
