Robotics & Engineering - Week of 11/03/25
Although this was a short week, I finally returned to the backup alarm circuit and wiring for the Ford Think (golf cart) which had been previously abandoned.
Resuming where I left off, I found that the alarm was installed and there were power wires properly installed and routed, yet they remained unconnected. From past experience, upon applying power to the alarm, it will sound a (loud) continuous tone rather than the classic beeps we hear on trucks. In order to combat this, I figured using a simple 555 timer circuit would be appropriate, rather than setting up an entire MCU and programming it to simply output a square wave.
I let Jonas build a prototype on the breadboard with a LED which worked out just fine. After that was confirmed to work, I helped him transition his work to a circuit schematic and eventually a PCB layout.
Once that was done, I milled it out on the Bantam PCB mill, which worked flawlessly.
The soldering is OK, but its definitely not my cleanest work! I’m a little rusty with proto boards.
