Now, there's a brilliant design!
All I'll need to do is to add some LED's, a power supply, twin processors, a load of software bugs, long wires a few switches and the Microsoft logo and Awwwway we go.... Full time shaking the money tree!

Dean, Thanks for the encouragement! :sad: You are right, it is a complex task and everything you mentioned has been considered. There are also environmental issues as well. Humidity, chemical composition, temperature all affect paper's properties. This is really a time sensitive project. Right now u...

jwax, I think ou idea has merit but it appears to be way high tech for the 'mundane' job of plucking staples. Maybe after all else fails, it is really the only way to go. R&D budget? What's that? At this stage it looks like a fishing expedition by one large customer to see what's floating in the...

Hey guys, thanks for the feedback! I'll look into these suggestions but rest assured, some of these companies scan thousands of documents per day. I have one friend that works for a company that contracts document scanning. He rotates from county to county, sometimes for months at a time, with a cre...

Ok, I'll open this door at the risk that it may be a little off track, but, It might turn out to be more Hi-Tech then it looks! There is a real need in the document scanning business to detect and remove staples from the sheets before they are scanned. On a small scale, this is trivial, but when tho...

If the indicator isn't 'cast-in-stone' to be an LED what's wrong with a neon? Use a commercial quality front panel relampable holder for a bayonet based neon, and a series dropping resistor for the current limiting. Although the resistor will probably last forever you could hang it on a terminal str...

Good luck on the Greenlee punches. Seems that round and a few 'DB'series connectors is what is available today. Here's a trick I use for odd panel cutouts that may work. First lay out all the cutouts with a CAD program, to full scale. Add a target for the exact center of each cutout then print it. U...

Comment on Comp USA... A while back I was in a Comp USA store early on a Saturday morning and saw a sales clerk loading software packages from a group of display shelves into carts, leaving only a few packages behind. Sunday, the software that was being removed was the focus of a big discount promot...

for what it's worth, 'resistance heating 'does have it's place, but it's not the soldering toy being sold. We use resistance heating to do precision brazing, with heavy carbon electrodes and high current transformers. Although more costly, for portable soldering the butane powered soldering irons ou...

For what it's worth, 480/277/240 primary transformere ARE readily available. Get out of the electronic catalogs and go to industrial suppliers. Many exit lights that are battery backed up use them for the operation of the low voltage lights and the battery charger. FYI 277 volt lighting is primarily...

Look at this! I have a rather large quantity of intercom control parts, like the switch systems that are/were common in schools. The list includes many Rauland control centers, switch racks and power amplifiers. There is even a few Bogen and Telecor items in the group. The equipment was removed from...

Jollyrgr, It does look as though the JC Whitney clock is a solid option. Power is no issue and according to the info. it has a bezel. I guess the most significant issue is the fact that this console will cost about $40K, must pass muster with the 'engineer' and I don't want a 'cheap shot' to cause m...

Joe,

May luck be with you!
