Meec custom cordless drill battery and charging station

At the Kaunas Makerspace that I visit very often to do various projects, most tools there are donated, some are bought and some tools are self-made (like a spot-welder that I used to connect batteries).

In the case of cordless drills the situation was never good. There are a few of them, but all are missing batteries or have dead packs and sometimes when you need to screw or drill something a bit it’s a little annoying, so we made a few from old LiPo (18650) cells that we salvaged from laptop batteries for Meec cordless drills. They have a very neat battery holder design – batteries simply slide in.

Making of the battery pack is easy, hardest part was to make a case for them and of course a charging station.

BBQ blower v3

This is my third attempt at making my life easier with maintaining a fire. I wrote about other attempts here and here and it looks like that this project has a never ending continuity, since it’s such a useful device…

This device (like previous ones) are to ensure I keep my eyes out of smoke and lungs in proper working condition and this version design was inspired by other devices that are for sale on Amazon or eBay, but they are chinese made tools and require batteries to work… I thought I could make it a bit better with rechargeable batteries, a small display to see how much power is left, a normal on-off switch and possibly with a better air volume output. Also as an added bonus I thought I could use it to inflate a mattress a bit, so that I don’t have to do it with my mouth and then sit down a bit being dizzy AF. Obviously this doesn’t create enough pressure to inflate it all the way though.

I remember a scene in a “Tom and Jerry” cartoon episode “Barbecue brawl” where spike was blowing into charcoal to get the fire going and of course that didn’t go well, if only he had this device though :D
