AR-II Test Bench PICTURES!

Use the RC input to the 555 instead of the output, and you'll get a lower amplitude sawtooth that may sound less harsh.

Thanks! I'll give that a try.

Very Nice. I love seeing other people's custom test equipment and thank you for taking the time to document it and share it with us.

okay, i've got 4 -5 boxes (probably more) of AR boards. guess I'll be making one of these. may be contacting you for a little more clarification once I get to building this. If it is anything like any of my other projects, it will get interrupted and will languish in a box by my work bench until the day that I really really need it about 4 years from now.

I'd sure like a follow up on what you would do differently and anything a noob like me would need to be aware of when putting one together. Thanks for the documentation. This will be very handy.

I guess the biggest thing I would have done differently is spent more time planning the layout of the box. I bought components without regard to how deep (shallow) the box was, and had to get creative to make everything fit. it would've been nice to be able to use a multi-pole rotary switch to ensure I stayed away from dangerous voltage-resistance combinations. Also, I had to remove and replace the load-board a couple of times. That was a pain! Oh, and build incrementally and test often.

I've got some additional docs on the AR-II and power supply pinouts and can give you more information if you need it.

That would great, I am also looking forward to the labels when you have them done
