| Description for Image 1: Test circuitry on a breadboard. It works. This uses a PIC, a CMOS4067, common cathode 7-Segment displays and 8 resistors. It can control up to 16 7-Segment displays without additional hardware/software. | |
| Description for Image 2: cardboard display holder for demonstration and testing purposes | |
| Description for Image 3: here all 16 displays hooked up, 2nd PIC for communication w/ PC all on the breadboard, with the displays stuck in a piece of cardboard to hold them | |
| Description for Image 4: behind the cardboard... you can see solder side of the displays | |
| Description for Image 5: another angle, closeup | |
| Description for Image 6: yet another angle the solder spool is used here to keep the U-shaped cardboard from falling over | |
| Description for Image 7: overallview of the breadboard | |
| Description for Image 8: the communications PIC with a MAX232 and its capacitors | |
| Description for Image 9: the display PIC and the 4067 (note: the PIC is the smaller one :-) | |
| Description for Image 10: ditto | |
| Description for Image 11: overall breadboard, this time a sharper image | |
| Description for Image 12: front of the cardboard all displays run in time-multiplex. ie. each is lighted up for a few msec, then the next. this keeps the component count down :) | |
| Description for Image 13: closeup | |
| Description for Image 14: one of the display units w/o the cardboard | |
| Description for Image 15: the back of the same, with the solder side | |
