anyone building anything cool? This can be Analog or Digital or really anything.

I found a couple breadboard the other day in my closet and figured i might as well start fucking around with something useful in my spare time so i decided to build a couple of fuzz pedals. After like 10 minutes of intense research i was shocked to realize how intense the markup is for something so simple as single or two stage amplifiers and a hand painted metal box.

I don't think they make these anymore, but $400... for that freakin circuit. My roommates have been asking me to build a couple of light switching circuits to run off of audio signals, but i've been too lazy and its much easier to just buy one.

Anyways what you guys got?

i watched a guy at my old work design a guitair distortion pedal called the "dirty sanchez".

it had an FPGA inside and emulated a rotating speaker.

worked in the computer simulation, i never saw it in action. ehe

That's pretty cool, no idea how that works. I'm just getting to signal processing classes now, z transform intrigues me. Maybe ill soon know how some of those delay/reverb/modulation ICs work. Everything I know now basically stems from linearity and it will be a nice expansion, but I definitley want to get into some other simple non audio circuits at somepoint in the near future.

I didn't even know there were students at all on TWW

^it's funny cuz it's true

so anybody done any etching?

the stripboard shit takes way too much effort. I've found a couple of guides but does anyone have any tips from personal experience? First order of business is buying a laser printer

i used to build a lot of pedals, but i can't remember the site... somewhere there is a big DIY guitar pedal site. There's a guy in Cary who makes a bunch of the PCBs and sells them for cheap.

Do some detective work and you can have easy access to PCBs

I cant count how many boards I've etched. If you have specific questions, drop me a PM.

so what you're saying is that i don't exist?

$1.89 for the components, $398.11 for knowing where to put them
