A three-part laser shooting gallery: a blaster, a control case and a bar of Porg targets that calibrate themselves and count how many you saved.

A resin-printed Star Wars thermal detonator prop with self-built electronics: a red arming LED, three blinking front LEDs and a synchronised sound sequence.

A resin-printed F-11D blaster replica with entirely self-designed electronics: barrel LEDs, sound, an ammo counter and a scope on its own microcontroller.

A hand-held six-button soundboard for cosplay, built on an Adafruit Audio FX board and feeding any AUX speaker through a standard audio jack.
