A buddy of mine runs a ring of food trucks, and told me his dream: a stylish lamp that could clearly tell his customers when the kitchen was about to close. Thus, the Last Call Lamp was born!
My goals for this device were twofold: to allow me to *see* the coolant circulating thru my Laser Cutter, and observe its temperature in real time.
It was a bummer to discover that my retail air-assist nozzle didn’t fit, but in 30 minutes I made & installed something even better!
I have a few ideas for score displays, an they’re all over the place. As the project grows, I’ll keep track of my research & prototypes here.
As my first really practical laser cutting project, I created an acrylic enclosure for a voltage regulator.
The K40 lasers are legendary for their shoddy quality and unreliable components, but as far as I can tell, those might be issues of the past! I’ve been getting excellent results—here’s what’s it took to get there.
Joysticks… Really this whole thing is because I wanted to make something with joysticks. But now that we’re here, I have a few other great ideas.
This Arduino Mega is the heart and soul of this project, and I’m hoping that I can use its enormous 54 pin-count to interface all of systems.
At this point the system needs 120v AC, 12v & 5v DC, and I’ve designed a prototype power supply to deliver just that… And more.
