Scanner/Color/ Test board

[mixedgas]

[QUOTE=Doc;117599]Hows about the new Steve Roberts PALMS tester? (Portable Analogue Linearity, Modulation & Scan tester), it's like a test bench in the palm of your hand.

Works for me. Although I spend 20 minutes on a bike trying to come up with a acyronym that matched STFU.

Fred Fenning (RIP) was so cool. I had dinner with him at a German restaurant in Seoul Korea at the 1988 olympics...good times.

I dont know anything about your board steve but it sounds cool to me

Does it have to be STFU? How about a less faith-based acronym, like
"Scanner Control And Testing" board.
"SCAT" can be used to determine if your equipment has shit the bed (or was shit to begin with)

Whatever you call it, I'm buying one, just my $0.02 (0.012 EUR +VAT)

Ok, its a PALMSCAN !!!

Lets summerize:

1 led for testing ILDA interlock loop/continuity checker
2. Scope mode
3. Quad Square
4 60-100 hz circle
5. a ramp for color linearity
6. R,G,B pots for forcing color (buffered)
7. A TTL signal on a button
8. Two diff to single ended and two single ended to diff
9. A slow RGB signal locked to the quad square.
10. buffered 0-5 signal
11. All outputs zener clipped and current limited for protection.
12. Signal integrater/averager
13. Bring out the violet line just in case.
14. DB25 in, DB25 Out.
15. A stereo attenuator to scale a +/-0-5V signal down to line level and AC coupled (scannermusic!)
16. A Fenning "Pulse"

That should do it.

Pat,

I never met him, I'm curious, engineer type or very artistic?

There is a reason the ILDA awards for technology are called Fenning Awards:

I like his stuff, its sophisticated, but you can look at it and repair it. The schematics flipbooks attached to the gear and the places to snap in a screwdriver to replace a fuse are classic. The amps often have 2-3 different types of fuseholder in parallel, for when your touring and can only get a nonstandard fuse. Also you can bypass just about everything to get a show up. Built in diagnostics. All on 22 pin cards, just swap out...
Really solid stuff.

Bring out the I channel as well in case someone like me uses an easlylase (or other RGBI) and is misusing the I channel for Indigo :-)

PALMs tester, you guys have a one track mind....

I would classify him as a brilliant technical artist. I think he was a EE at least. The team of IEC back then was very artistic oriented with technical abilities. I followed a few of those leads, my goal was to design equipment to only need the small swiss army knife and a set of bondus allen drivers to get from the road case to the scaffolding. If you carried more tools...you were building the system on site.

Sounds like the board is a "tool" that everyone will like!

Hey Steve,
I was wondering if the physical board dimensions are "in flux", if it would be convenient to find a small device (cheap & existing) that could be used as a donor chassis.
I was thinking you might be able to get a stack of these, then base the physical board dimension off the existing board in the donor chassis. That way you could have a ready-made handy little box for under 9 bucks, probably even less if we looked around.
Just a thought- I have Dremeled out a fair share of db25 holes in the last week or so, so this is my way of avoiding more
edit- here's a different one for 5 bucks

I like the way you're thinking, Steve. This idea of yours is going to be very useful! Keep up the awesome work, and I hope you've started a list of people that want to be in on the first production run of these things...
