Yeah, those Radio shack boards are great. Digikey has a bunch of various sized perfboards too.

The 417 hole board looks perfect, the other won't take the 24 pin pad. Great rec, thanks!

Use one for the 20 pin, the other for the 24 (IIRC) and the extra holes are for cooling.
Very Happy

What IC holders did you get, Bill?
My order is from Mouser and I could not find gold plated sockets in stock.

Digikey 24 pin EDS6243-ND and 20 pin EDS6203-ND

Also the NPN which I hope is the right spec 497-2598-ND 40V 600mA TO-18

The relay Reed DPST 500mA 12V 306-1035-ND

I forgot to get an DC input jack but I can get that from rat Shack with the perf boards

What else do I need?

Thanks, Bill. I'll post my bill of goods tomorrow.

The relay, transistor and sockets are all correct.

Now you just need a power supply. I like using a center tapped 12V transformer, rectifier, filter cap, a 7809 and 7905 to make +/-5V then onto a 317 and 337 to make +/-2.5v. This is seriously overkill having two regulators. But each of the regulators is like sixty cents a piece, so having all that noise filtering is cheap.

Could do it with a rectifier, filter cap and a pair of Zeners. Or could go with the modules like Bruce did. But no matter how you slice it, you gotta have +/-2.5V.

Here's my BOM minus the PS stuff because I took a different approach. I am not sure if the caps in the IR rcvr circuit (1.0/.1uF) should be polarized electrolytic. Wayne?

I made my order at Mouser. Bill, I could not find the parts using the numbers you supplied for the gold sockets at Digikey. Could you verify those?

Relays:
-NEC EA2-12NJ (signal relay) x5
-Omron G4W-2214P-US-HP-DC12 (switched power relay) x1
-220R x6
-2N222 x6
IR Receiver:
-TSOP 4838
-1.0uF
-.1uF
-220R
Display (LED Meter):
-LM3916 x2
-1.2KR x2
-7.5KR x2
-2.2uF tantalum x2
Momentary Switches:
-http://www.parts-express.com/pe/showdetl.cfm?Partnumber=060-622 x6

Those filter caps across the power line for the chips and IR module can be pretty much anything. Electrolytic is fine.

20 pin = ed56203-nd
24 pin = ed56243-nd
relay reed 306-1035-nd
trans 497-2598-nd

they all check out, you have to place the dash before the nd where applicable

What are you doing about the power supply? That's what I'm hung up on...15 to 7.5 to 5 to 2.5 volts? Yikes! Can't begin with a 5 volt tranny?

Wayne, got parts for that?
