The Power Supply needs to handle 30ma per circuit. We used 5VDC at 500ma. You also get another bonus, the PSX-AR LED will flash when it's
reversed. Both the PSX and PSX-AR are on solid when shorted. We added a two pin terminal to the PSX boards to avoid soldering wires and make changing easy. Less chance of damage. The connector goes on the Remote Status connections. PSX J5 Pins 1-2.
PSX-AR J5 Pins 3-4. Not the same.
Construction: We used proto-board for each of the 14 circuit boards. We built them all identical except for the number of circuits.
Pictures are included. Each LED needs a resistor, remember you cannot put LEDs in parallel. All the parts come from Jameco. Below is the
parts list. Be careful if you use small solid copper wire, it can break easily. Once installed it reliable.
Parts List per circuit:
- 15K resistor ½ or ¼ watt ($0.04)
- 470 resistor ½ or ¼ watt ($0.04)
- 2N3904 transistor ($0.06) (178597)
- H11A1 or equivalent ($0.29) (878286)
- Connectors – euro style ($1.15 for 12 connections) (215011)
- LED’s (red) (3) ($0.24)
- 5VDC 500ma wall wart (one for project)
- Buzzer ($2.95)(1956696)
- 2 pin terminal ($.39) (2094506)
- 6 pin IC socket ($0.13)(683091)
The H11A1 does one circuit.
The Buzzer for each PSX product is 1956696, prices have gone up ($1.25-2.95). The PSX puts out 5VDC max. You may need
to bend the leads to fit the holes in the board. You will want the buzzer.
