The mad scientist in me could not resist creating a steampunk inspired case for the alarm receiver that goes with my driveway alarm.
The workings are based on a NodeMCU with some LEDs and a passive buzzer. It flashes and beeps in the event that anyone triggers the IR beams across the driveway.
The case is made from odd scraps of sapele or similar timber I had in the shed and a 3D printed insert.
It's adorned with some watch cogs and gears, some tiny glass bottles, some brass bar, and copper wire.

| The components to fit in |
The aerial end of the NodeMCU is deliberately inside the plastic dome to minimise the wireless absorption that it might have had from the timber.

| Lemmy, helping, again :-) |
The copper wire is connected to two capacitive touch switches.

| Solder a connector on to the touch pad |
I've used off the shelf capacitive switches from e-bay, as usual.
The large coil acknowledges the alarm and resets the LED's and the small staple like wires silences the alarm for a few minutes as well as resetting the LED's.
The bottles are filled with two part epoxy resin that I coloured with a few drops of acrylic paint at the mixing stage. I made a paper tube to avoid getting the resin on the rim of the tiny bottles.
