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

555 is a very useful and popular device. See, we're mostly a bunch of gearheads that assemble electronic products. For help with your design, look here: http://www.google.com/search?sourceid=navclient&ie=UTF-8&q=555+timer+circuits

Where can I find the "hours run" timer on this oven. Can't locate a physical timer. Is there one located in the software?

Oven runs, input/output sensors work but no product tracking. Various resets have no effect and cannot reset Drive Cycle Timer due to "not calibrated" error. Where can I find the procedure without manuals on-hand?

We use timers all over our shop to keep track of pot life on epoxy, paste work time, etc. The timers we use are from "Big Clock" or someone like that. They cost about $10. They keep time, count time up [run time] and count down from a set time. [

I would like to design a small delay timer circuit to activate from a switch that when it is N/O it starts timing for two seconds and then activates a buzzer. I am trying to use a 555 timer with a buzzer attached running from a two lithium 3v batteri
