OT: Did they take the backup feature out of MS-Works?
|
| |
Gents, Using MS-Works for databases and most spreadsheets. Mostly database though and there I always run the automatic feature "Backup the previous version when saving". Long story short a new PC came with a license of the newest MS-Works, version 8.5. Can't find the backup feature. Arrgh! Did they take it out? If so is there anyone at MS whom I could toss into... more »

JFET gain control "resistor" in Weinbridge oscillator
|
| |
Hi All, This is my first time posting though I’ve read some of the discussions. I’ve been having problems with some of the Weinbridge oscillators that are in our lockin amplifiers. I won’t bore you with details, but a circuit that was working for years now seems to be having problems. I used a light bulb as the gain control element.... more »

making a new RFID reader vs. modifying an existing one
|
| |
I'm trying to decide whether it would take less time to make a new RFID reader using an antenna from an existing unit as well as using the code (to produce the fsk signal) as well as the circuit used to match the antenna's resonant frequency. The existing unit is made of an antenna made out of coils of lacqured copper wire. There is an... more »
