Post by thread:UV Question - slightly off topic

How come EPROM chips don't glow purple/blue when we program them? It seems that all those 1's should be going back where they came from (the UV light we pump into them in the eraser). <G> Andy ================================================================== Andy Kunz - Montana Design - 409 S 6th St - Phillipsburg, NJ 08865 Hardware & Software for Industry & R/C Hobbies "Go fast, turn right, and keep the wet side down!" ==================================================================

Actually if you get a really good microscope and a low light camera - I'm sure you'd see something... Rgds Mike Perth, Western Australia

I distantly remember reading that most semiconductors emit a little infrared like a LED so you might just try a very sensative IR detector and see if you get some output. Martin McCormick

I'd like to take all the CO2 exhaust gasses from cars all over the world and convert it back to petrol/gas. And of course sell it back to you again... Maybe if I pumped the co2 *really* hard up the exhaust pipe I'd fill up the tank.... -- Eric van Es | Cape Town, South Africa spam_OUTvanesTakeThisOuTilink.nis.za | http://www.nis.za/~vanes LOOKING FOR TEMPORARY / HOLIDAY ACCOMODATION? http://www.nis.za/~vanes/accom.htm

Well - feed it over a heated (~400C) platinum/osmium catalyst and inject some dry steam at around 10 atmospheres and make some methanol and maybe a small amount of err alcohol as well - maybe you could put it all in a trailer ;-) Actually quite an easy process in principle, could use a control micro of course...

Instead of having Air Products Inc. (and the like) return the unneeded gases to the atmosphere, we can eliminate the atmosphere! Certainly would solve the air pollution problem those NZ sheep are creating <G> Andy ================================================================== Andy Kunz - Montana Design - 409 S 6th St - Phillipsburg, NJ 08865 Hardware & Software for Industry & R/C Hobbies "Go fast, turn right, and keep the wet side down!" ==================================================================

Well quite straightforward:- 1. Thermocouple sensors (usual range 100C to 600C approx) 2. Pressure sensor ah la motorola 3. Hot wire mass air flow sensor - ah la Bosch 4. Industrial spec'd PIC in peltier cooler if you really want short wire links to the thermocouple ;-) 4. Accelerometer to measure the 'Gee whiz' forces when you get the mixture wrong and it blows up in yer face! rgds ;-) Mike Perth, Western Australia
