hello, ok i got an 24v power supply going to a POT. i then get 5V from the POT. the POT is 2 watts 5k. The laser lights are pulling 65MA and are 5V This will not work? if i connect it to The pot it, the voltage drop is too much.. now the question is what kind of POT should i get? more or less watts or ohms, and whould it have any effect on the 24Vs comming in...(iam using the 24 volts for another divice) any help would be good thanks. glen

just thoght i would BUMP this on up...... thanks.

hope this works... for you or at least helps its the chart for the phone Feq. http://nemesis.lonestar.org/reference/telecom/signaling/dtmf.html

you could detect the pulses with any computer device if you plan on using a computer then program it to count when the input recives a signal and stop counting when the signal goes low. then just X the time by money..... i hope it is ok to give links... but i used a company called measurement computing and you can get a device there that could do this.... iam sure there are different ways and maybe even better but i just like programming the computer interface devices... cheers...

you mean a PHONE? lol just playing

hello, i was wondering if anyone has any skmatic on a 0-24volt power supply with maybe 1a. i would like 120v ac in so i can plug it in easy and up o 24 dc out for testing small designs.. thanks glen

just wondering if anyone knows of any more good contest...

you know you can make the desgin and send it out someone will make it on a board like 60 dollars..

there are some good devices like the PMD1024 it is from measurement computing that you can program in c and are eazy to learn.. also on Ebay you can find some nice kits. for like 5-10 dollars.

here it is ...the biggest site ever for all chip info http://www.repairfaq.org/filipg/LINK/GIICM/giicm_idx.html
