Another Lap Timing System
I called my system as Club Timing System. This post is dedicated to the assembly of the system of counting laps.
1. preparing PCB and photoresist. board is two-sided. lower layer is used as screen and grounding at the same time
2. gluing photoresist to the workpiece by the laminator
3. preparing photo template
4. imposing a photo template on the workpiece further illuminates the UV lamp
5.illuminated areas are clearly visible on the photoresist they would not be washed by soda solution
6.after development of the photoresist pattern we get clean picture
7. Next is etching of the board
8. after etching we get this beauty
9. drilling the board
10. cutting unwanted ends
11.final drilling
12. here pictured 0.3mm lanes
13. adding one more layer of photoresist for the mask
14.translucent board and washing off the excess photoresist
15. soldering the board and ground on it
16. soldering first microchips
17. soldering other elements
18. for flashing bootloader add jumpers
19.shorting contacts of the bootloader and giving voltage
20.run the firmware bootloader. bat file knows how to flash and FUSE bits of the butloder.
21. open AVRPROG, choose firmware, press Programm (COM port must be 1-4 otherwise it would not work properly)
22. flashing starts
23. cut the lanes from ground and +5 volts from USB because they would not be used in future also unsoldering old jumpers from RESET and CLK
24. soldering plume to the screen
25. checking it`s work
26.Work on the bugs. To + 5V and -5V on linear regulator requires balanced load. Hang resistors at the input to each 470ohms and output 5V
27.Connect the programmer on FT2232RL for program epm240t100c5n
28. Run the bat file to flash CPLD
29. It can be assumed that the digital part of the decoder is finished.
30. This is what gives us a timing system in the terminal. everything works
