    i need help extending the keys finder project. can someone help me out????

    the circuit is beeping but not blinking. i knwo there is something wrong on how i wired it.. i tried several times but it is still not blinking. i think it has somehting to do with the LED battery's polarity.. i used a BC337 for Q2.. i just log in on MSn after 3 hours.. you could be awake by...

    Op-Amp Circuits Program 1.00

    hi keldean! i went to the link given by Ante.. since it didn't automatically download, i have to get it manualy.. i got a zip file.. however, i can't open it.. i think the problem is with extracting it.. i just have to re-download it i guess.. assuming all is fine, with dloading and extracting...

    i need help extending the keys finder project. can someone help me out????

    i appreciate making the schematic for me, but i will use a different supply for the LED.. so there would be a 3V lithium cell for the circuit and 3 button cells for the LED..

    i need help extending the keys finder project. can someone help me out????

    i really don't have a choice.. i have to make my thesis defense whether the circuit is working or not. i doesn't matter. my defense will only take 4 hours at most! ;D grounding pin5 makes it beep? this is to show the the oscillator works, right? i need to make it beep during the defnse to show...

    Op-Amp Circuits Program 1.00

    Hi Ante! Thanks.. what is it anyway? i have downloaded its zip file. i tried opening it but winzip cannot extract it. as you have mentioned it needs VB, maybe that is the reason. i'll founf it out when i got home. i have VB installed in my pc.. maybe this would also solve another problem in...

    i need help extending the keys finder project. can someone help me out????

    ahh.. audioguru.. i wanted to make the circuit work as much as you do, but i think i need to concentrate on the 4049 since it was the IC used in the manuscript i presented to the panelist.. and during the defense, that is the circuit they are expecting to see.. i know it would be best to show...

    PCB too large!

    the text written is "Electronics 2002 http://electronics.cjb.net" i think it was the old address of the eLab.. dont mind the text written on the design. it was just placed there as an ad or something.. you may even not include that in you actual PCB.. just dont forget that it was the brains of...

    Op-Amp Circuits Program 1.00

    i have downloaded a program about op-amps http://www.electronics-lab.com/downloads/calculators/010/index.html.. after extraction, three files opened, one of which is opamp.exe.. i can't run it.. something about VBRUN100.DLL and cannot find the file, and somethin' with libraries..

    that was cool! i mean hot! ehehe.. one of my thesis proposal ideas was a soldering iron with a built-in desoldering pump.. it was just too crazy..  :P

    PCB too large!

    when you resized it, the "lock aspect ratio" on the Format Picture toolbar should be unchecked.. then simply enter your desired dimensions.. This depends on you. you can remove it by using the crop command. in MS WORD, it's placed in the picture toolbar.. to better "trim" the picture, hold down...

    schematic to pcb software?

    it took me more than 45 minutes (that is minus the failed attempts) to download EAGLE.. the connection in the cafe is just too slow.. i hope i can easily figure how to work with EAGLE..

    i need help extending the keys finder project. can someone help me out????

    i will now begin troubleshooting the circuit again using the 4069.. we have tried lots of things on MSN, yet it still continuously beep.. i pointed out that maybe, at some point in that testing, my buzzer got damaged that is why we have to stop working on it? if you will continue help me working...
