BSIAB/Tripple Fuzz Build Report with pics

[soggybag]

I have been working on designing a standard template that would allow the stomp switch, in and out jacks and DC power jack all to be mounted to the PCB and wired with traces on the board.

I decided to use the 1590B as my first template. I have 1590BB box template planned as the next project.

I started with a piece of perfboard as my prototype. I cut it to fit and measured holes for jacks and switch.

Here's a picture of the board with jacks and switches. I decided later to move the DC jack to the right.

As a first project I made Tim Ecobedo's Tripple Fuzz. Here's picture before I put in the transistors.

Here's the whole thing in a box.

The first project was a BSIAB 2. But I finished the Tripple Fuzz first. Here's the BSIAB 2. This used the same template. I bought the two of the large size perfboards from RS and made about 4 templates.

Here it is with the pots.

The first two effects were sort of a proof of concept to see if the idea would work. And it seemed to fit in the box pretty well. So I made up a PCB design in ExpressPCB and 3 prototype boards printed. I used the "Miniboard" service which meant that boards had to 3" by 4". Here's an image of one of the three boards. Front side

Here's the board with parts mounted to it.


I sketched out some rough layouts of some other effects that I want to build using this template. I figure since the BSIAB has 5 transisitors and it fit, that it would be possible to fit most effects of this complexity or less into the template. I figure you could squeeze the TS-808 and variants on it also.

I posted a short tutorial with pics describing the process on my website.

The PCBs made by ExpressPCB have all of the traces that wire up the stomp switch, DC jack and both in and out jacks. It runs a ground trace around the perimiter and has a connection set up for the LED on one of the poles of the switch. There is pads for a reverse polarity protection diode next to the DC jack. A power trace runs up to the perfboard area as do traces for FX in and out.

I'm planning to print up more of these boards for myself. I would like to offer them to list members. At first look it seems they would cost from $6 to $10 each depending on quantity. If anyone is interested buying some of these let me know.

The prototype boards were made double sided with solder mask. I'm thinking that the final boards would not need to be this fancy. I'm thinking to save on the cost to have them made single side no solder mask.

NOTE: I have only ordered the three prototypes at this time. I will be ordering some in the next week or so. The number ordered will depend on how many I think people might want.
