Using Eagle, I drew up a schematic for a 6-digit score display with an I2C interface, and had it autoroute a two-sided board for the schematic: That sounded easy, but it took many days to add each part to the Eagle libraries so that it knew where the pads were and how big each [...]
Having drawn my idea for a layer drive, I went to NextFab, cut the casing parts out of acrylic on the laser cutter, wrote a quick gcode program to produce the brass pieces on the CNC mill, and put it together. Twice, because the first time I learned some things, and the second time I [...]
I have the logic for a 16-bit Logical Mill worked out and verified. Now, I have calculated that a 16-bit Logical Mill will require approximately 1,200 rods, and 5,500 bumps. The average rod is approximately 13 inches long, thus the total length of rods would be somewhere around 1,300 feet. That is about USD 500, [...]
Here are the rods for the demo function. They are steel, 1/4″ x 1/8″. I ran keyways down the middle of each, 0.015 deep on both sides. I might add keys to the aluminum blocks that go on the rods so that the blocks don’t rotate. The holes are 0.3125″ apart, which corresponds to half [...]
Wherein a partial demonstration model is displayed to allay the concerns of the Exchequer.
In which a form of mass production is attained.
Wherein the first parts direct from the workshop are displayed, and a name change is set forth.
This was my test project to practice using NextFab’s Trotech laser engraver/cutter. It is 1/4″ black acrylic into which I engraved a four-level image of one of my cats. The engraving process I think is much more suited to just bilevel images, but this worked pretty well! Meow!
Wherein we are awed by the awesome awesomeness that is a fully-equipped makerspace in Philadelphia.
