jeb Posted February 18, 2007 Report Share Posted February 18, 2007 hello,i'm building a unit with 2 lines of 16 pots... so there isa lots of wires !has somebody tried to design a pot board (single-side pcb...) with as few wires as possible, andjust a pin header in order to connect something thatlooks like a 40pins IDE (hard disk) cable... ?thanks in advance for any idea or photos !jeb Quote Link to comment Share on other sites More sharing options...
pay_c Posted February 21, 2007 Report Share Posted February 21, 2007 Normally a normal stripboard is ideal for that, I did that a dozen times. Put the pots there in a row and only drill the middle strips open between every pot. Outer and inner strip goes to GND/5V. The rest can be soldered to some connection port (SIL header or whatever).Greetz Quote Link to comment Share on other sites More sharing options...
jeb Posted February 21, 2007 Author Report Share Posted February 21, 2007 hello,maybe i should try stripboard but just a question :let 1 2 3 represent the 3 pins of the pot, and --- the strip.should i do : --------- 1 2 3 ---------- 1 2 3 ------------ 1 2 3then the pots are in serial !! and on pin #2 i can't getthe 0v-5v range !!shouldn't i do this ?|-------------------|--------------------------------|----- 1 2 3 --| | 1 2 3 | |------------ |------------------------with the first line (0v) connected to each pin #1and the third line (5v) connected to each pin #3 thanks in advance,or maybe could you send me a photo of such a "stripboardpot board" !jeb Quote Link to comment Share on other sites More sharing options...
pay_c Posted February 21, 2007 Report Share Posted February 21, 2007 --------1-------1-------1------>+5V---x----2---x---2---x---2--------------3-------3-------3------>GNDx: Drill there ;D Quote Link to comment Share on other sites More sharing options...
Sinnsyk Posted February 21, 2007 Report Share Posted February 21, 2007 LX has a great way of solving that:http://www.lx.czweb.org/modules/mod-btns.htmget some inspiration ;) Quote Link to comment Share on other sites More sharing options...

MRE Posted February 25, 2007 Report Share Posted February 25, 2007 Another option is to thread enamal wire through the holes of the pot tabs. It looks like bare wire but is coated with clear enamal paint. Take care to keep the wire from pot to pot short so that the slack wont short to to anything else. Now rub a part of the wire with a knife right where you want to solder to the pot tab and solder it in place.now you just need one new (normal) wire for each pot.Pots next to each other in a row: (arrange all tabs facing the same direction)It helps to bend one set of tabs slightly up, and one set of tabs slightly down, with the signal wire left in the middle. Thus, "high tabs" )all left tabs)= + and "low tabs" (all right tabs)= - and the signal wire helps to keep the two away from each other. [] [] [] []--------o------------o---------o------------o -----s ----s ----s -----s------------o------------o----------o------------oPots in a column:With all tabs aligned the same direction, wire all the left tabs together and all the right tabs together. Make sure your design allows for space between the pot body and wire. If it does not, then wrap each pot body in electrical tape before building up, that way if a part of the enamal wire is bare and touching a pot, it wont short.I cant make a good ascii pic of this one :(An alternative to enamal wire is wire wrap wire. loop it through, then twist it twice. When you solder to the tab, you actually have to melt through the insulation, but it does work. (do it in a ventelated space! ;) Quote Link to comment Share on other sites More sharing options...
audiocommander Posted February 25, 2007 Report Share Posted February 25, 2007 I cant make a good ascii pic of this oneyou can wrap your ascii drawing with [ tt ] [tt]to select a teletype font with unified spaces[/tt] [ \tt ] ...or just click the typing machine icon in the reply toolbar ;)Cheers!Michael Quote Link to comment Share on other sites More sharing options...
MRE Posted March 1, 2007 Report Share Posted March 1, 2007 hehe.. I COULD do that.. and spend.. like.. EFFORT on it! BAH! ;)Actually, it wasnt so much of a spacing thing as it was being lazy! Making the other picture would have been a column of things.. tedious.. and the wires on the sides would be loopy.. like ( bah.. too much work! :P Quote Link to comment Share on other sites More sharing options...
