Interesting swamp cooler

OK this one is pretty funny, its a trash can converted with a filter and a fan.  Nice build overall.  It could be cheaper if the author used something beside aluminum brackets.

Nice write up on making a wooden mallet

Could be a good build with scrape hardwoods.

Nice build for light up bike rims

I like the build, the author does a good job on it and making sure you get it on the rim below where the brakes would rub.  I also like the custom 3D printed LED holders.

Make a simple battery welder

Nice simple build.  If you have the parts, worth making.  If not…you can get one from China for $50.

Cool circular saw track

A bit different than other builds, more for making miter cuts on larger pieces of wood.

A better inner tube cutter

I like this tube cutter better than a one from a few weeks ago.  I still think it could be simplified more thought.

Automatic pool filler

Nice and simple build with some PVC pipe and a toilet tank filler.

Oh several modifications to this have been to use the Korky Universal Fit Adjustable Toilet Fill Valve (Model # 528MPK), which looks nicer

Nice build for extending your backpack

And recycling bike inner tubes.  Doesn’t look too time consuming either.

OK this was pretty cool build.  I am not 100% sure what is going on to make the build, but it looks nice.

Cool coffee cup CNC

I like this CNC, you stick it on a coffee cup and it draws  on the cup.  Its still a work in progress.  But seems impressive sofar.
