So I've been using a craptastic stir plate made from some magnets, an old cell phone charger, and a computer fan with broken blades. It got the job done most of the time but I wanted something nicer. Coincidentally my brother recently has gotten into etching his own PCBs with his CNC mill and was looking for a project. Long story short, I now have an overkill stir plate... and I had to brag to someone about it. I need to snap some pics this evening, but a quick summary of features is:
-RPM readout on a blue LCD display
-LCD is backlit and automatically dims after a certain amount of time
-LCD brightness & contrast, dim timeout duration, and dimming functions are all user configurable through the UI
-RS232 connection in the rear for updating software
He considered it the "barebones" version in the end and still wants to make a second one with bluetooth control and other completely unnecessary features. I can't complain though because the thing ended up being quiet and it is pretty cool.
As I mentioned before, I'll put some pics up this evening of the thing.
