 You can turn your toy lightsaber into a high-quality build with Adafruit's ARPY 2040 prop maker feather and Circuit Python. This toy lightsaber features a detachable blade that we were able to upgrade with a strip of Neopixels. We gutted the toy's electronics and added the ARPY 2040 prop maker feather. We really like the injection molded parts, so there's no 3D printing in this project. The original blade only has around 20 LEDs, so we swapped them out for a strip of Neopixels for getting better animations that can be set to any color. The stock blade has white LEDs that show noticeable dark spots when compared to our Neopixel blade. The Circuit Python code has customizable settings for colors and you can adjust the sensitivity of the swings so you can make it match your preference. You can also swap out the audio files to make it super custom. To learn how to upgrade your toy lightsaber, go to learn.adafruit.com Get the parts to build this project, links are in the description. Start by removing the pommel, then remove the screw from the battery cover. The two halves are held together with just a few screws so it's easy to take apart. Carefully unplug the connectors from the main board and desolder the wires from the various components. You can splice wires to extend the cable from the pogo pin connector. Attach a 2-pin JST cable to the terminals on the battery holder so we can plug it into the feather. The wires from the button can be attached to the prop maker's screw block terminals. You'll need to cut the trace on the back of the feather to disable lipocharging so we can safely use alkaline batteries. Add another JST cable for the power switch and insulate the exposed pins with some capped-on tape to avoid shorting. Then we can plug everything together and close it back up. Take apart the blade by removing the screws from the pogo pin connector, then remove the plastic pin from the tube. Carefully slide out the diffuser and take out the LED PCB while keeping the cover and diffuser inside the tube. Now we can solder the wires from the pogo pin connector to our strip of neopixels. Then we can fit it into the diffuser sleeve and slide it back into the tube. Place the covers of the pogo pin connector back onto the blade and secure it using the screws. We think this makes our toy lightsaber so much better and really like how we were able to use most of the electronics. We hope this inspires you to upgrade your toy props with Circuit Python and the ARC-B2040 Promaker Feather.
