PCB Font

Can anyone tell me how he got those fonts on this PCB? It sounds like he had the design sent out. I've only seen PCBs come back with vector fonts.

    Some newer PCB CAD programs (e.g. CADINT 4.x) can use TrueType fonts. But even without those, it's possible to import vector files, such as those in HPGL plotter format. I've done this with fonts and logos on PCBs using CADINT 3.5, wherein the text or logo is designed in CorelDraw, then exported as HPGL. When this is done, you can specify the spacing for the "fill" lines, which a pen plotter would use to darken the interior of outlined objects, such as letters. Then, when the HPGL file is imported to the PCB CAD program, you choose the thickness of those lines (i.e. traces) such that they just overlap.

    Thanks for the explanation. It sounds like the gerber files he sent to the manufacturer had vector fonts in them. So maybe whomever made the boards converted them back to proportional?

    I'm only asking because I basically borrowed his idea, but with a propeller chip in stead of a PIC. I'm about to order 110 in^2 of boards from China. I'd get a prototype made first normally, but since I don't care that much of if the boards actually work, I'll take the gamble.

    Slightly off the original topic; has anyone tried running the propeller at slow speed on a single CR2032? I'm planning on only running one LED at a time. And I have some blue LEDs that should only sink 5~10 mA with 3V. Assuming the Prop even works with battery.

    I've tried running the propeller with 2 x CR2032 connected in parallel at 80
    MHz - it doesn't work at least with brown-out detection enabled.

    I suspected it wouldn't run with a crystal. Maybe with just rcslow?
