Adding a coolant system to harbor freight bandsaw

Nice build. I worked in a machine shop in the past and adding coolant to a cutter can extend the cutter’s blades lift and make smoother cuts. I love the catch tray he added on. Note there are 2 videos for the build.

clever crane build for truck

I like how it uses a pull out leg for support, and an electric winch. Unfortunately most US trucks don’t have a gap in the frame to do this, of course the bed on this looks homemade too, so I guess you could “put” a gap in.

Making realistic flapping dragon wings

For a costume. Nice build overall with an arduino controlling the wings.

Use RemoteXY to control a robot arduino

Basically its a wizard for creating an “app” to control an arduino via wireless. Seems pretty neat.

Making a pinwheel from a soda can.

Nice build, Only thing I would do a bit different is how the shaft/pinwheel is connected together.

Another nice CNC for hot-wire cutter

This one is pretty impressive in that its more 3D than other foam cutters I have seen that are 2D. It has the base build similar to a rep-rap.

Interesting clamp

The author made some really long clamps. I like the wedge build to secure the end. My 2 cents, pipe clamp kits are under $5, and the pipe another $8….they don’t look as nice thought.

Converting a nail light to a UV light for resin prints

With a resin printer, you also will need a UV curing station to harden the final print. These can be a bit costly, but the author modified a home salon light to do this instead.

Upgrading a cheap CNC

The author upgrades a 1610 (also can do 3018) to the size of a 5050, which is like 50 mm to 500mm. According to the author, it was cheaper than buying a 5050, and he did some other upgrades that are not on the standard 5050, so it seems like a good deal. Not sure on the cost difference thought. As far as I can tell, they all use the same spindle motor, so the swap should work out.

Neat pan/til camera build

Or you can use it for other items (like a laser pointer). The build it all from 3D printed parts, 2 stepper motors, and an arduino with CNC shield. The sample videos show its moves pretty quick and smooth.
