This is a variable frequency oscillator controlled by an arduino with an LCD screen, touch pad and rotary encoder for configuration.

This is something I built for a friend of mine to control his motorized dog feeder he built. He had a disc that would spin when a motor moved to dispense dog food from a hopper. This is the arduino part of the project that he used to control the motor.

This is one of the components of the full sized yoda I'm printing. I'm using an awesome program called LuBan to scale the model up and split it up into pieces that will fit on my printer along with indexing pins and holes.

This is a summary of what you should be doing :)

I'm working right now on printing a full sized Yoda figure. I took the standard Yoda figure on thingiverse, and using a program called Luban I scaled it up to full size and then split it into pieces that will fit on my Ender 5 Plus build area (340x340x500). Here's a video of the right side of his head being printed. Luban has a ton of other features including being able to make lithopanes, puzzles, stacks that can be cut with a laser cut, it's an awesome program!! https://www.luban3d.com/

Great little soldering kit

This is a cerambot that I'm helping someone with by putting it together for them, this is the first test run of it. Still have to mount the clay pump, pump controller board and install belt tensioners and the wooden bed but it's running great!!!

Trying to print a handle on the mug this time with my Cerambot. Need to tweak the settings some more but after it gets leatherhard I'll hit it with scotchbrite and make it smooth :)

A bowl I designed using Openscad and the extrude function printed on a Cerambot printer. One of the steppers missed some steps near the end and it shifted so I stopped the print, I'l clean up the boogers after it dries a bit

Modified my model a bit so that the opening that I need to cut out is a depression now so it will support the print but it'll be easy to cut out and I added some drain holes in the bottom. The hanger didn't print very big so I'll make it larger, and I'm going to make one drain hole in the center so it doesn't do the funky patterns while printing the base.

Second attempt in printing a bird house. First one fell apart when I tried to cut out the hole and shake out some debris inside. This one I actually was successful adding a 'hanger' on the top that I'll drill out after it's leather hard, and that's when I'll cut the hole as well. I printed this at 1.5mm layer height with a 4.4 mm nozzle and it's much beefier I think :)

Another large 3d printed mug, largest thing I've printed on my Cerambot printer. Finally have it dialed in and working well.

I bought some barb fittings from home depot and didn't use the extruder module and I was able to push much more clay out. The clay I have now is a bit too soft, but now that I've eliminated the biggest restriction in the flow I can use stiffer clay.
