If you want to make your own PCBs use schematic diagram picture. Solder angled 2x5 goldpin like on the picture (first put it in the IDC connector of the multicolor flat cable).Solder all 60 LEDs watching polarization (longer and shorted legs) as shown on pictures īend 60 LEDs like on the picture (it is easier if you will use something which has 90 degree angle and has around 8-10mm long flat surface).Tin should be visible on both sides of the PCB It is maximum value of current for Arduino I/O Pin. Do not use diodes with current over 40mA. if diode specification says 2V, 20mA value of resistor would be R=(5V-2V)/0,02A=150ohm. If you use other diodes you have to calculate value of resistors. If you use DIY KIT take 150ohm resistors for red / green leds or 91ohm for blue. Take one round PCB, 60 LEDs in one color and 9 resistors.of 10pin IDC-IDC ribbon rainbow cable if you don't have IDC crimp tool. * - Instead of point 12 i 13 you can buy 2pcs. Arduino male female rainbow cables (optional).10mm screw sleeve spacers male-female 14pcs.20mm screw sleeve spacers female-female 8pcs.10mm screw sleeve spacers female-female 5pcs.Clock consumes very little energy so any USB port or USB power adapter can be used. USB Cable for Arduino board and USB Power source.heat shrink tube 5mm diameter ~5cm long.heat shrink tube 3mm diameter ~100cm long.Flat multicolour (rainbow) cable with 10 different colour wires 3pcs.If you plan to use different LEDs than these in DIY KIT, you should calculate value of resistors based on your LEDs specification.)
#Shadow digital clock 3d printed code
You can use other arduino compatibile RTC but you have to remember to change source code libraries. But of course if you want to try anyway there will be schematic diagram of matrix in next steps. It is almost certain that it will not work correctly because of the ghosting effect (well known issue with big charlieplexing matrixes). I don't recommend to replace it with cable wiring or homemade PCB.
#Shadow digital clock 3d printed professional
It is strongly recommended to use professional PCBs, well masked with proper distance between circuit paths.
The key to this project is the DIY-friendliness. Much of his original work was lost in a computer crash so we recreated his work. 22lr and then I was contacted by FreeMenDontAsk via Twitter where he told me he had a method for making 9mm Glock pistols that worked well.
This is the result of several months of experimentation in order to have a base Glock platform that the gun community can design around. The notes from his ReadMe state the following:
