OK, I have a project that I am looking at, that would be easier if I used a membrane keypad. This is a small production setup, say 50 per year, with several differnet configurations. Anyone have experiance with any of the membrance keypad folks? What I really want is a master keypad with all configurations, and then perhaps 4 or 5 different overlays for the different configurations. I have to justify the cost of doing this, vs the old method of a set of toggle switches and thumbwheel switches, both in reliabity and mfg cost of all the point to point wiring. Comments anyone? You may reply to me directly at spam_OUThcooperTakeThisOuTes.com thanks

Only comment I have, is how reliable will it be!. I repair TV's etc, the failure rate of membrane keypads is HUGE!. I've seen some TV's that require them replacing about once a year or so, this particular TV manufacturer has sourced the pads from various manufacturers, none seemed any better.

I try not to post non-pic stuff, but I am sorta desperate on this, and since this does reach a vast group of folks.. I have an HP Vector Impedance Meter, HP4815A, but the probe is bad, and the repair place says no parts are available to fix. Does anyone have one, or know anyplace that might still have parts or a new probe for this? Or worse case, a VIM for sale? thanks in advance Harrison Cooper

Perhaps we should standardize a "Subject" heading that could be included in the beginning all all off-topic messeges. Then, those of us using procmail could filter all of the unrelated messages. I personally like reading all of the emails and getting to know the different personalities, but, sometimes I'm in a hurry and just was PIC info. I think a standard, such as the short one above would work very fluidly. -- Garrick Kremesec Beckman Institute - RA http://www.cen.uiuc.edu/~gkremese @spam@gkremeseKILLspamuiuc.edu

I made similar comment, but suggested ltuae as trigger word (life, the universe, and everything - for those who want acronym explanation) - would be good for two reasons - a filter for the poor pic archive, and, as you say, allow list members to move it to either delete folder or a 'when I've got time' folder.

We've been experimenting with various methods of labeling prototype front panels. The latest trick is use iron-on transfers run thru an ink jet printer. It's a bit tricky, but it works. I'm wondering, however, about using a flat bed plotter to print such panels. I've got this Houston Instruments DMP-29 plotter (from way before I generated Gerber files for PCBs). Anyone have any ideas about pens that could be used in that to write on aluminum panels? Thanks!

Sure, what you need is an instant drying pen like those used by photographers to write on the front of photo's. You can always check a photo store, but I have been using a common office waterproof pen lately with great results on all surfaces. Try the Staedler LumoColor AV permanent pens. These are designed for overhead projectors. There are similar non-permanent pens available from Staedler, so be sure you get the right ones. The giveaway is the words "Permanent" and "Waterproof" and the Staedler number 313. I usually use the S size, but you can get them in several tip sizes. Start with the S though, I think it is your best bet. My local Office Depot and Grand & Toy stores carry them individually and in packs of four colours (black, red, blue and green). Incidentally, I suspect this pen would make a good etchant resist too for those interested in plotting PCB pattern directly to copper. Good luck - Martin. spamBeGonemrgreenspamBeGoneNOSPAMbigfoot.com Remove the NOSPAM from this email address before replying. Stamp out SPAM everywhere!!!

Holes can be easily cut out with a scalpel, either after sticking to the (pre-drilled) panel or beforehand if they are marked on the label. This gives a very durable and quite reasonable looking label for very little effort. You just need to be careful to avoid bubbles under the film. ____ ____ _/ L_/ Mike Harrison / White Wing Logic / RemoveMEwwlTakeThisOuTnetcomuk.co.uk _/ L_/ _/ W_/ Hardware & Software design / PCB Design / Consultancy _/ W_/ /_W_/ Industrial / Computer Peripherals / Hazardous Area /_W_/

Sorry about the OT-ness of this one, but I figured this is just one of those things that maybe SOMEONE will be interested in. Audiophiles: I have a good size box, say maybe 20 records, of classical (Mozart et al) music on 78RPM disks. These are all in very good to excellent condition. Anybody want them? I just don't have a use for them - they don't fit in my CD drive <G> Motorheads: I have a 1976 Honda Civic 1200cc engine in my office/garage which would really like a new home. If you or anybody you know races full-size boats, this is the engine to beat in the "Z" 1.5 liter modified class. It's a strong engine. I pulled it from the car because the body was Swiss cheese. Tranny and electrical systems are still on it. Rebuilt at 150K (now 200K) just to have something to do one summer. Cylinders have NO ovals, and were within factory-ship tolerances when rebuilt (it was run on AMSOIL most of its life). Still on stock (but new) rings and very good compression. Either of these is free + S/H. Warning - the engine will cost about $250 to ship to Washington State (I live in NJ). Thanks.
