From Firebomb to improvised explosive deVice

[davent]

Hello All,

How do you make a SHO even better...

... make a Firebomb. To the Firebomb circuit added a Geofex polarity protection scheme that uses an IRFD9024 MOSFET, added a second/parallel 100Ω/100µF filter so each SHO has it's own PS filter and added a trimmer after the first boost to trim it back if deemed necessary. Used ExpressPCB to do the layout and then Inkscape to dress things up and create a pseudo silkscreen. PCB painted with acrylics to disguise the puky natural colour. Am getting away with 30K resistors for current limiting on the LED's so with everything running i'm looking at only ~2ma.

Shielded cable was used for the long runs between jacks and switches... needed?

Assembly jig used to do all wiring except to the jacks. Do the jacks once the assembled components are mounted in the enclosure.

For painting the enclosure i first use a self-etching primer then over that coat with BIN Primer Sealer Stain-Killer, nice high solids, sands well and is white.

After that, acrylic paints and mediums, India Ink, toner transfers, flakes of rust, paint and dirt. Applied stuff with whatever's handy, paintbrushes, airbrushes, fingers, dip pens and pallet knives/spatulas.  Lots of paint removal in the finishing process, water while paints are wet, sandpaper, files and rifflers, dental picks etc. The play/experiments... to be continued...

Clearcoat is airbrushed Target 7000 waterborne lacquer.

I.R.D., improvised 'riting device, pop-can-pen.

See ya'

sweet artwork on that one.  and it looks like it's built like a tank!

[Hangingmonkey]

wow, just wow, your pedals are works of art.  Thanks for sharing the work in progress pics.
For your next pedal, if you did a video showing how you did the art or the texturing on the background, im sure it would go down really well.

2 words....Mad Genius

I'm so impressed by the artistic style. You and Matt in South Africa are doing some pretty rad art on those boxes.

Anyway. kudos man. Get a soundclip up and get this thing in this months contest!

SO INSPIRING. Thanks so much for posting your process and sharing it with us. I have sat here on the couch for the last 30 minutes staring at your photos and wondering how I can better my process. You have a great process and look to your pedals.
