In order to make a mini flashlight, you will need everything in the picture below:
- Soldering iron and all accessories in place with it (Tin (solder) and rosin or flux)
- glue gun,
- Stationery knife,
- A plastic box (you can also from another material),
- switch (key),
- Fee with LEDs (Can be bought at a flea market, price: no more than 25 rubles)
- Battery crown 9V
- Connector from crown (9V)
STEP 1
Take the box and make two holes in it, one in the lid (large, under the LED board), the second for the switch (very small).
STEP 2
Solder the wiring (not very long, but not too short, depending on the size of your box) to the switch and to the LED board. (on the board it says where (+) and where (-).)
STEP 3
We fill the switch with the hot glue and the hole made for it in advance, and the board too.
STEP 4
Soldered in series: Krona, switch, then board. (In no case should you break the polarity !!!)
STEP 5
We insulate the wires with electrical tape in order to avoid a short circuit (when bare wires come into contact)
STEP 6 FINAL.
Now close the lid from the plastic box and test)))
If you did everything as described above, then you must succeed!)))
