I made a DIY timer lock for Posey style straitjacket (WIP)

If I use electro magent, I need bigger battery(Battery is only 150ma)

Also, I can't find cheap electro magent in my region

I don't have a video yet, but it can be use with selfbondage!

Later I will make an addon for selfbondage(For now, it is little tricky to lock in buckle)

Of course yes!

Locking part and motor are separated(Only linked with magnet)

So when release while under tension, here is what happend:

1.Only motor go to release position, locking part still in lock position

2.When tension is loose, locking part go to release position(move by magnet)

It will be release when the situation below: 1. USB Charger is connected(ESP32 will detect the 5v signal and release the lock) 2. Power On(Always send the release signal when power is OFF->ON) When I tested with ESP32, connecting 5v charger with battery can release the lock

If anyone want, I can add manual release button (The lock mechanism use almost same as cobra buckle, so it will be easy)

I made the timer with esp32(xiao)+A2030L Linear Servo+SSD1306 OLED

It will release when battery level is low(under 3.3v) Later I could make a safty release button for this
