The point is to charge the battery during the day, then completelty drain it at night by use of a light sensor.. I thought that due to the low current of the solar panel it wouldnt be a problem if i used a 6 Volt battery.. do i hook + to - or + to

Block protection of Flash ROM

Electronics Forum | Tue Nov 09 21:20:28 EST 1999 | Gyver

Hello all, Recently, we had a bad problem of block protection. You know, our programmer can't protect the 29F002 flash ROM, and our motherboard doesn't have 12 volts output for BIOS. So, from the preceding phenomena, it seems impossible to get a prot

We're getting field failures in a high impedance portion of the circuit. Think the unpopulated pc card has contaminates because we were able to grow dendrites by applying a 9 volt battery across the suspected pad, placed a drop of de-ionized water o

Electronics Forum | Wed Nov 14 00:38:45 EST 2001 | jarvis76

Does anyone have experience with the zsct1555 timer chip made by Zetex? I can't seem to get it to oscillate properly. My values for vcc and components are as follows: Vcc=1.5v Ra=220 ohm Rb=3200 ohm Ct=100uf OR..... If you know of any other chips

It looks like we'll have to go the conductive process tray route. I looked through web sites for Brick Container and several other esd suppliers and did not find anything that would work. I saw the tray you mentioned in my Techni-tool catalog, but wa
