hello all,

i purchased a kit to make a looper from the isd25xxx series of chips, and instead of building it on the providing pcb, i tried to be a clever clogs and do a layout in loch master and build it straight onto strip board. thing is, it doesnt work, and i dont know wether its my layout or what. would anybody be interested in doing a layout if i provide them with the schematic?

let me know

cheers

bebn

hi bebn
why not use the pcb?
If it doesn´t work check everything again -step by step.
Check your layout - connection by connection. You´ll see if it´s ok. Then check every component - right place? - soldering ok? Use a ohm meter.
Check if the powersupply reaches the chips. Change active components
In 99,5% of all cases you´ll have found the error by now. Frustrating, especially for the beginner. You´ll get used to it and start finding mistakes really fast with some practice.
I would like to see that shematic.
good luck

yes, it's probably best if i spend a while checking it over myself. i wanted to make it on strip board so i could make more should it work. i'm just worried now that i've probably made a massive mistake when designing it. i'll try and get a copy of the schematic up this week if i can find someone with a scanner i can use

cheers
