Using an arduino, IR sensor, and a servo, the author built a pretty simple conversion for a pump action soap dispenser. Could be a simple project to do with kids.

Pretty amazing build. Most builds involve using a shop vac in it, this one, the author re-purposes a blower motor.

Nice build, the bucket used is a good idea. LED’s are a bit pricy for the project (individual addressed LED’s are not cheap).

basically you made a plotter that uses water as the “dots” to print out as you ride along. Cool idea.

The author made this build for a scope based webcam that he could hold a circuit board down on and solder components too. Me…yeah I don’t go that small in boards (and usually use thru hole). But I could see repurposing this for other builds.

This can be used not just for angled cuts, but to “straighten” out boards that have a curve to them. Relatively simple build too.

Good way to wash off dogs or yourself. It uses a weed sprayer bottle, and a shower head extension. The one bit I got that was interesting is the incoming tube in the sprayer may have restrictors in them that need to be removed (so you get a good flow of water). Oh and I get a kick out of the author trying to put the barbed end of the adapter onto the hose (I would have heated up the tube to get it over).

Very nice build. A bit more work than I would do thought.
Interesting build, pretty simple build too.
Nice build done with mostly hand tools and a table saw
