voltage question (pedalboard)

[vendettav]

so I have a 1spot. love the thing.
I need to get 5 v out of it for my pedalboard lights (2x USB LED light) but it also powers other pedals. I'd also want to put a brightness control on the LED thing. so I'm thinking of a box for that

what do, DIYSB?

one of these would help you get you 5 volts

you need a few extra parts though

dont mix up the ins and outs , i usually see em flip flopped , this diagram ^ seems mirrored to me .



you may also wish to calculate how much current draw the leds will pull and consider that when purchasing the regulator . i would also think about some sort of heat sink for the 7805 .

light show for the pedal board , thats awesome . i did a google search for mini fog machine but ...

The 7805/78M05/78L05 series does not need any resistors or pots.  The schematic shown is for an LM317 and note that the input is on the right and the output on the left in the schematic above.  For the 7805 series, you need an input capacitor to ground, an output capacitor to ground and the 7805.  Three parts only.

and can you tell me what cap it should be?

and can you tell me what cap it should be?

I use, like the picture, 100u and 10u, and sometimes a .1 across the 10u (the .1 helped me quiet some ticking from LFO, and other clock sources). Sometimes, depending on the circuit, I'll drop a 47u at the output instead of the 10, but you should be good with 10u/.1u on the output, and 100u on the input. Not sure about a .1 at the input, though.

kk thanks, I'm using it for LEDs so I dont think I'll be having issues with ticking

Yes, 1 Spot's are nice.  Too bad they don't make an 18V model.  I thought they used to make a 12V, but I don't see those anymore.
