Alright, let me tell you about this little project I just wrapped up – a rechargeable pump water thingy. It all started because I was tired of lugging those heavy water bottles around. Seriously, my back was killing me!

The Idea

So, the idea was simple: build a small, portable, rechargeable water pump. Something I could stick on top of a big water jug and easily pump water out. No more lifting, no more spills (hopefully!).

Gathering the Parts

First things first, I needed some parts. I hit up my local electronics store and grabbed the following:

• A small 12V water pump (the kind used in aquariums).
• A rechargeable 12V battery.
• A charging module for the battery (TP4056 is my go-to).
• Some tubing that would fit the pump inlet and outlet.
• A switch (on/off, you know the deal).
• Some wires and connectors.
• An empty plastic bottle (for the housing).

Building the Housing

The housing was the trickiest part. I chopped up that plastic bottle and started experimenting. I wanted something that would securely hold the pump and battery, but also be easy to disassemble for charging or maintenance. After a few failed attempts (and a lot of hot glue), I managed to create a decent little box. I cut holes for the tubing, switch, and charging port.

Wiring It All Up

This was the fun part! I connected the battery to the charging module, making sure to get the polarity right (don't want any sparks!). Then, I wired the charging module to the charging port. Next, I connected the battery to the switch, and from the switch to the water pump. I used connectors so I could easily disconnect things if needed. I even added a little LED to indicate when the pump was running – just for kicks.

Testing and Tweaking

Time to test! I stuck the pump in a jug of water, flipped the switch, and… nothing. Uh oh. After a bit of troubleshooting (turns out I had a loose connection), it finally sprang to life! Water flowed! Victory! But it wasn't perfect. The pump was a bit noisy, and the flow rate was a little slower than I wanted. I tried adjusting the voltage, but that didn't help much. I ended up swapping out the tubing for a wider diameter, which improved the flow rate significantly.

Final Touches

I secured everything inside the housing with more hot glue (I'm telling you, that stuff is a lifesaver). I added a little rubber foot to the bottom of the housing to prevent it from sliding around. And finally, I gave it a good cleaning.

The Result

And there you have it – my rechargeable pump water dispenser! It's not pretty, but it works. Now I can easily fill my water bottle without breaking my back. Plus, it's a fun little DIY project that I can be proud of.

What I Learned

This project taught me a few things:

• Hot glue is your friend (but be careful not to burn yourself!).
• Always double-check your wiring.
• Don't be afraid to experiment.

Overall, it was a fun and rewarding project. And now, if you'll excuse me, I'm going to go refill my water bottle.
