I'm a Minecraft fan, and I wanted something cool for my desk that would actually work. So I built a working Minecraft TNT. It's 10x10x10 cm, just like my working jukebox, but to me, this TNT is way cooler.
Parts (links):
-DFPlayer mini
-Perfboard 40x60mm
Screw and inserts:
4x M2.5x8mm screw
6x M2.5x4mm screw
2x M2.5x14mm screw
4x M2.5x4mm Heat insert
Springs:
1x 50x13mm normal spring
4x torsion spring 15x30mm
A very detailed guide, including the electronic schematic, is available here
How to Reset TNT:
Reset the side panels:
Loosen the two screws holding the servo plate, re-hook the 4 arms into position, and tighten the screws back down.
Lock the top lid:
Manually push the top servo latch back towards the battery holder. it needs to touch it.
Power cycle the TNT (turn it off and back on).
You now have a 15-second window: place the top lid on and hold it down gently until the servo automatically moves and locks it into place.
I did everything myself from the ground up so I would really appreciate it if you could rate this model. If you have any questions about the code or wiring, just ask me in the comments or send me DM!
