PunkRockerLuke Posted July 26, 2006 Author Report Share Posted July 26, 2006 can somebody add a SPSP switch to this diagram? http://runoffgroove.com/ruby.html this is what I'm using http://www.radioshack.com/product/index.js...rentPage=search And how can I test LEDs to see if they work???? And if I wanted to add a red LED to the amp how would I go about doing this? Luke, May I suggest that you check out these basic tutorials. http://www.iguanalabs.com/maintut.htm They will help you understand some of the questions you are asking. There is even one on LEDs. Hope you find this usefull. Mike there is nothing there about adding an on/off SPST switch to a diagram. but thanks for link it did answer my LED question.

ihocky2 Posted July 26, 2006 Report Share Posted July 26, 2006 If you want to operate an LED off the same toggle switch you want to switch to a DPST or a DPDT and just flip in only one direction. Quote Link to comment Share on other sites More sharing options...
PunkRockerLuke Posted July 26, 2006 Author Report Share Posted July 26, 2006 I've decided not to use an LED and because I don't have a 7/16" drill bit I've decide to buy this switch instead of the one with the on/off lable plate since it mounts in a 1/4" hole instead of a 7/16" hole. http://www.radioshack.com/product/index.js...rentPage=family Quote Link to comment Share on other sites More sharing options...
PunkRockerLuke Posted July 26, 2006 Author Report Share Posted July 26, 2006 OK in another thread here on PG i read that the .047uf and 0.1uf capacitors are poly, so is the what I'm needing to get??? http://www.radioshack.com/product/index.js...rentPage=search Quote Link to comment Share on other sites More sharing options...
PunkRockerLuke Posted July 27, 2006 Author Report Share Posted July 27, 2006 And is this the correct type of capacitor to use with the one above??? http://www.smallbearelec.com/Detail.bok?no=162 Quote Link to comment Share on other sites More sharing options...

crafty Posted July 28, 2006 Report Share Posted July 28, 2006 Dude, where's the fire? Those capacitors will work fine. Also, just wire your switch into the red wire coming off your 9v battery connector--it'll just turn the power on and off. Quote Link to comment Share on other sites More sharing options...

PunkRockerLuke Posted July 28, 2006 Author Report Share Posted July 28, 2006 would I still be able to use a SPST switch with this LED??? http://www.radioshack.com/product/index.js...rentPage=search Quote Link to comment Share on other sites More sharing options...

Ben Posted July 29, 2006 Report Share Posted July 29, 2006 As far as I can tell from the pic, thats just an ordinaty LED with a little plastic enclosure round it, so yes. It just looks pretty much identical, execpt it has wires in the place of the legs on normal LED. Quote Link to comment Share on other sites More sharing options...
ihocky2 Posted July 31, 2006 Report Share Posted July 31, 2006 Make sure you find out all of the specs on the LED first. If you are set on using a SPST switch, you will have to run the LED in series with the switch, which means it is being fed full voltage. So you will have to make sure there is not too much voltage or amperage in the circuit to fry out the LED. And if you add resistors to cut the amperage, you will lose power through the rest of the amp. If the amp and the LED need two different voltages or currents, you will need to provide a seperate power supply (like a watch type battery) and either a second swith or a DP switch.

crafty Posted July 31, 2006 Report Share Posted July 31, 2006 An LED is probably not going to take enough amperage from the circuit to affect performance. Just run the LED in parallel with the switch with a 1k ohm resistor in series with the LED to bring down the supply voltage to the LED's operating voltage.

ihocky2 Posted July 31, 2006 Report Share Posted July 31, 2006 I wasn't refering as much to LED affecting the circuit, as I was to there being too much power flowing through the LED and frying it out. For some reason I forgot about wiring it parallel with a resistor. I was just working with an LED project that I did exactly that. I guess that's what I get for trying to think on Monday morning.

PunkRockerLuke Posted July 31, 2006 Author Report Share Posted July 31, 2006 today I bought the SPST switch and the IC socket. I only had enough $ for those two. Quote Link to comment Share on other sites More sharing options...
PunkRockerLuke Posted August 18, 2006 Author Report Share Posted August 18, 2006 does anybody know where I can get knobs like the ones on the DOD supra distortion pedal??? Quote Link to comment Share on other sites More sharing options...
mammoth guitars Posted August 18, 2006 Report Share Posted August 18, 2006 The DOD line of pedals all use the same knob. The digitech pedal knobs are cool too. Quote Link to comment Share on other sites More sharing options...
PunkRockerLuke Posted August 19, 2006 Author Report Share Posted August 19, 2006 that isn't were to get them Quote Link to comment Share on other sites More sharing options...
PunkRockerLuke Posted September 17, 2006 Author Report Share Posted September 17, 2006 well schools started and moneys even shorter than ever so I have to either see if the high schools electrical classes teachers will let me borrow some of their parts and some perfboard or ditch it. And does anybody know where the hell I can get DoD supra distortion knobs with the gray tops??????????? Quote Link to comment Share on other sites More sharing options...
PunkRockerLuke Posted September 17, 2006 Author Report Share Posted September 17, 2006 Or should I switch to the little gem???? I've still got the same parts but I have 2 5mm LEDs (will trade other 1 for 3mm greeen/red LED in housing. red on top green on bottom) (or will trade for single 3mm green LED) http://www.generalguitargadgets.com/pdf/gg...tle_gem_pcb.pdf is that how big the PCB actually is?????????? If it is who designed it a smurf??????? Quote Link to comment Share on other sites More sharing options...
PunkRockerLuke Posted September 17, 2006 Author Report Share Posted September 17, 2006 Hello?????? Anybody have an answer to my question?????? Quote Link to comment Share on other sites More sharing options...
Southpa Posted September 17, 2006 Report Share Posted September 17, 2006 Have patience, I'm sure someone will be able to help you out. As far as where to get DOD distortion pedal knobs... how about from a DOD distortion pedal? Maybe find one that doesn't work and scavenge parts from it? Or just contact the company directly and ask if they can spare a few knobs. And yes, I guess thats how big the PCB actually is, 2cm X 4 cm. Ya gotta do a bit more research for your project dude and quit relying on the people here for ALL of your needs. This forum is primarily for guitar building, but your approach is scaring away all the guys who might be able to really help you out. Sorry for sounding a bit critical but there ARE other forums that specialize in electronics, amp building etc. etc. Quote Link to comment Share on other sites More sharing options...
PunkRockerLuke Posted September 17, 2006 Author Report Share Posted September 17, 2006 one last question (I may be able to get all the parts I need for the little gem today) for the little gem on another site I saw in their parts list it uses a 25ohm rheastat. Could I use the radioshack 25ohm 3 watt rheostat or coul I use the 10k ohm linear taper pot used in the ruby amp for the volume control as the volume control in the little gem??????? please reply as soon as humanly possible Quote Link to comment Share on other sites More sharing options...
