Once upon a time, I received a Rothult cabinet lock from IKEA as a possibility for grinder hardware that could lock a container even there it wasn't a highly secure method. For $20USD, it was worth investigating, and the equipment within was robust for the price. While opening my own lock, I searched for someone else who had done the same and found a resource. Someone in the HaD comment section found the same article, so they were credited with the find.
My Electronic WindChimes project took a detour so that a rudimentary drum machine could feed a tempo to the unit and provide the percussion. I picked basic hardware that would be quick for construction. The controller plugged into a socket where the points were broken out to screw terminals, and all the buttons were a single board with touch-sensitive pads. The touchpad rested on a piezo element for feedback on how had a button was pressed. In a way, it was a pressure sensing pad that could detect which of eight sections had been touched.
All the connections needed testing. The rotary switch would change modes, and there was a problem with the switch where a washer was misplaced and disabled everything. The next relationship was between the controller and switches with found a cold solder joint. For the MIDI output, a program sent a single note every second and the synthesizer had no trouble receiving it.
Programming started with mode one which sent a MIDI note on channel ten when a button was touched. The note's velocity was determined by the analog input from the piezo element under the button pad.
Mode two set the tempo by treating all the buttons as a single input and recording the time between taps to set the speed. After talking with a musician, I found out this is called "tap tempo."
The third mode created a loop based on the tempo and instruments touched. While in this mode, the loop would cycle forever and instantly update whenever a new button was pressed. Velocity was recorded alongside the notes. Time for the cycle was determined by the tempo so many sounds could be crammed into a short span or a single sound could be played with a long time between iterations.
The rest of the summary posts have been arranged by date.
