Introduction: The "sweet" DIY Powerbank
Hello everyone, as my first instructable, I've created a tiny powerbank, entirely made using recycled parts.
Let's see how it's made!!
Step 1: Parts and Tools
You'll need just few things:
- a DC to DC module
- a big pack of Tic-Tac
- a battery (I used the one of an old useless Samsung phone)
- some wire to solder
- a welder pyrography
Step 2: Prepare Your Stuff
Now, you just have to follow this simple steps:
1) CUT THE WIRE: you'll need just few centimeters (or inches - hello America!!) of wire. Be sure not to use too much wire or you'll have troubles positioning everything inside the box
2) SOLDER: please make sure to solder the anode of the battery to the anode of the DC-DC (the same goes for the cathode) or your project's going to end up dead. In the pictures I highlighted them so you can distinguish them better
3) PUT THE BATTERY UNDER THE DC-DC: that's right. If you want your powerbank to fit inside the Tic-Tac box, you need to do this. Furthermore you may want to ensure the battery to the DC-DC using just a bit of black tape
Step 3: Prepare the Box
This one might start as the sweetest step ever. Why? Because you've got to empty the Tic-Tac box, so.. EAT THEM ALL!!!! I suggest you so to pick your favourite flavour, and maybe enjoy them while making this project.
Once empty, you need to cut the long side of the box, so you can easily plug your USB cable. I did this using the same welder pyrography I used to connect the battery to the DC-DC module, but in this case I replaced the soldering tip with a cutting tip. Anyway you can use a Dremel or other tools you like (just be VERY careful not to cut yourself) cause the plastic is very soft.
Step 4: Place the Powerbank Inside the Box and Use It
This is the final step: before putting your powerbank inside the already-cut box, you may want to put some double sided tape to the battery in order to firmly attach it to the wall of the box.
THAT'S IT, YOU FINALLY MADE IT. BRAVO!!!!
If want to charge your battery (like I did), now you can. Or either way, if want to charge your device, you can too.
