it is a rechargeable flashlight which we can control by hand's moves.
Iron man themed flashlight.
Step 1: What You Need...
here I use 13 White LEDs
-TP4056 charger circuit
- stainless steel wire
- plastic ring
- Li-iron battery
here I make simple hand control switch. I use magnets,PCB strip, metal ring
.- one diode (1N4007)
Step 2: Join All LEDs in PCB.
cut the round shep PCB.
And solder all LEDs parallel connection.
Step 3: Now Plastic Ring
here I use 350mm diameter plastic ring.
drill two holes.
you can make it by 3D printer.
after drilling holes placed in stainless steel wire.
Step 4: Led Circuit and Plastic Ring
join LED circuit and plastic ring using hot glue gun.
Step 5: Connection
Now make all connection as diagram.
solder positive terminal of battery to PCB strip.
solder Positive terminal of LEDs to metal ring.
and connect ground of battery to negative of LEDs
Step 6: Make a Switch
here I use PCB strip, magnets and metal ring.show on figure. solder positive terminal of battery to PCB strip.solder Positive terminal of LEDs to metal ring.
Step 7: Done
now fold the stainless steel wire size of hand.
