The only thing I can see  is that you soldered your output wire to the ring of a stereo jack , it should be on the tip lug where it was before ( or maybe Im wrong ) . So it`s probably not the only problem .

+1

In addition i think the red power wires should be connected on the other lug of the dc jack. The actual lug is not connected if you plug the power supply I think. Check the wiring carefully.

Of course it´s ok, It´s the same!:

0.022uf = 22n = 22000pf

Try here (http://stores.ebay.es/PARTSPIPE) or any other electronic related chinese ebay store.

I´ve seen some lighted switches looking around but not that ones, but you can try.

Here´s an example http://www.ebay.es/itm/8-CAR-BOAT-Fog-Light-Strobe-illuminated-SWITCH-B07D-/300724918628

I would go with multiple small transformers as opposed to one transformer with multiple secondaries. Small, dual secondary transformers should be easy to find, the ones i have have a dual 120v primaries  so are good for N.A. and Europe.

Curiously this was going to be my next question The benefits of use multiple transformers with one secondary or one with multiple secondaries. I´ll take a look at those articles, thanks!

Can I ask why? If you are creating a daisy-chained PS anyway, it would be far cheaper and simpler to just buy a onespot. That transformer is almost $60 by itself. A Onespot is about $20.
-P

Of course you can. The reason is I enjoy doing it and learning in the process plus then I feel good if I play with the guitar with things built by myself anyway I want to make all the outputs isolated, not daisy chain. The image was just to ask in the forum how does the current works in these situations.

1. i would put a large electrolytic capacitor across the output of the regulator, just to help smooth out the output a little further. a 10uF cap should work fine, but you can sorta put any large-ish value there. if you want to be extra cautious, you could put a large mylar cap in parallel with the electro (say, 0.1uf or so). in theory, this may help reduce high frequency noise.

2. it's a difficult calculation because it has to do with the output resistance of the regulator and the input resistance of the circuit being powered. it should suffice to say that any large value cap should do and the larger value the better.

3. yes, 1 is isolated, however 2 and 3 are not. this is less than ideal, i would consider redesigning so you can provide more isolated outputs. if you're going through the trouble of building this device, you may as well build it the best you can.

4. just to clarify, the 0.6A represents the maximum current draw before the transformer stops functioning. it does not mean 0.6A is constantly flowing through it. in other words, you should not have any pedal or pedals connected that draw more than 600mA (which is a fairly huge amount for most analog pedals). in the case of 2 and 3, any combination of pedals should equal less than 600mA.

good luck!

Wow, thanks for the information! I´m gonna read carefully all the points

I´m planning to build a power supply but I need help as I know only the basics.

The transformer I´m planning to buy is that http://www.ebay.es/itm/50W-R-Core-Transformer-220V-in-out-20V-2-15V-2-12V-Power-AMP-/230732843466 or something similar (any advice on choosing the right transformer is welcome, I have no idea on what It´s best for this project but keep in mind I´m in Europe, I can´t buy it from Weber, for example).

Attached is a picture of what I am working on (with more outputs): IC is lm7809 or similar and diodes are 1n400x (the diode between cap and Q1 is for protection, I don't know if it is needed)


So here are a bunch of questions I hope you can help me with.

1. Do I need other elements like a little filter cap for the regulator?
2. How I calculate the value of the filter cap(s)?
3. Since I use different bridge rectifiers, filter,... for each output. Would it be number 1 isolated with 2 and 3 but 2 and 3 themselves would´t between them?
4. If I get 0,6A from the secondary transformer on each 20/15/12V output. What current will I have on 2 and 3? 0,3 each?

Thank in advance for the help

Have them ship it to your work place, make it appear like it is work-related, and when they start asking questions, say its private!

Good to know that, I´ll try the next time.

I ordered one time the express shipping option for the same reason. I wanted to make the most of the weekend. I think it was $22 to Spain. The shipping was fast but the taxes were about 40€! near the price of the order (I think it was $50-60). So for me never again, I prefer to wait 15-20 days. Regular mail is rarely checked for customs.

You can leave it unconnected or connect it to ground. If you cut the lug is fine, thats what I do with my transistors.

Here's kind of a cool DIY inexpensive way to silk screen http://www.instructables.com/id/20-Portable-Silkscreen-Kit/

Thanks! I´m a fan of instructables

I´d be interested too

Envirotex is definitely one of the things i´m going to try. I´ve seen many build reports and seems really well.

I´m planning getting into silk screen too, not now but in the future. I know it is not the best option for only one pedal per design but I really enjoy doing that kind of things.

I have try some techniques and none of them convinces me. Etching is very good-looking but is hard and very unpredictable due to the attention you have to pay in each step. Transparent paper and adhesive paper is almost ok but I dont like the unprofessional looking if you look closer. I still have to test waterslide decals and dry decals (wich are almost nonexistent in Spain and Crafty comp.  for example asks me about 15€ of shipping costs for 2 or 3 papers). Laser etching is completely superb imo but I have the same problem, there are no many printers that manage that here.

So, what technique is in you opinion the best considering the materials are not hard to find and wich provides a professional looking?

And another question, what technique is the one used in comercial pedals and amps chassis? Silk screen printing?
