Software – 18F line Simon’s code is a great start For simple USB I/O projects Used by 4x4 Square, 4x4x4 Cube, 8x8 Matrix and 8x16 matrix Used “WFF” by Simon Inns for base MicroChips C18 compiler and USB library LED driver interrupt is written in assembly. Dwayne’s assembly is over 100 times more efficient. Microsoft C# for PC side, using Visual C Express. Blinkie – How you do that Musecon 2014

Have you looked at xxxx Texas Instruments MSP430? They offer a start kit for $10 Higher level CPU then PICs, easier to program, better support for “C”. Operate at volts, hard to driver Blue LEDs. They have 14 and 20 pin DIP versions. Pic has 8, 14, 18, 20, 28, 40, 64 Blinkie – How you do that Musecon 2014

Have you looked at xxxx PIC 32 bit line? Looks like a great chip! Saw some cheap pre-made boards using it. (Solution looking for a problem) See 8 have been release in SPDIP package. Not pin compatible with 18F line. Blinkie – How you do that Musecon 2014

Circuit Board Layout Avoid “Express PCB” and “Pad2Pad”. They are using proprietary formats that other board makers can not work with. You want something that generates Gerber RS-274X and NC Drill files. Open source is getting better PCB FreePCB KiCAD Avoid the “Free” circuit board layout software “roach hotel”. Your data can checkin but never checkout. Blinkie – How you do that Musecon 2014

Is UV dangerous? (Short)
Your Iris does not adjust for UV light. Dark room with bright UV bad. UV damages DNA. Blinkie – How you do that Musecon 2014

Is UV dangerous? (Long) High intensities of UVB light are hazardous to the eyes, and exposure can cause welder's flash (photokeratitis or arc eye) and may lead to cataracts, pterygium, and pinguecula formation. UVA, UVB, and UVC can all damage collagen fibers and, therefore, accelerate aging of the skin. Both UVA and UVB destroy vitamin A in skin, which may cause further damage. UVA can contribute to skin cancer via indirect DNA damage (free radicals and reactive oxygen species). It penetrates deeply but it does not cause sunburn. Blinkie – How you do that Musecon 2014
