LM386-based “Esteli” demo by Alex Wilson
an older video, but one i’ve been wanting to post for some time. this is Alex Wilson of Son Cats playing on one of the several cigar-box amps i’ve constructed.
Tag: LM386
Arduino: second verse, same as first… sort of
well, not really. feeble attempt and making some sort of microprocessor controlled tempo clock, but a good exercise in the ATMEGA328s finicky behavior. don’t ask me what that squeal is.
Arduino: Analog Aerials
Essentially the oBITerator program with aerials instead of actual input signal. Of course, we’ve got to mix in the newly constructed PT2399 pedal. A little work needs to happen in
The Esteli: an LM386N-based cigar box amp
The Esteli: Cigar Box instrument LM386N-based Amp from abram on Vimeo. Here’s the latest in general purpose amplifiers made from reused parts. The enclosure is an old cigar box for
Square-wave Oscillator Meets PT2399…
Square-wave Oscillator with PT2399… from abram on Vimeo. Very short video of the waveform captured using Xoscpe of the PT2399 applied to the LM386 square-wave oscillator. Sorry for the bad
LM386 Square-wave Oscillator
Here’s a small LM386-based square-wave oscillator built from the following schematic. I replaced the 30k resistor with a 50k Potentiometer from my stash of parts which then, of course, acts
LightBox prototype
here’s a small battery-powered guitar amp that i’ve constructed from reused parts. the housing is a busted computer power supply (some of which is in the No. 5) as well.
the final layout
She’s big and bulky, but you can’t ask for too much when you’re dealing with pre-printed PC boards. The 22k resistor in the gain path makes for extremely high output
the first of four…
This was my first attempt at building the circuit on the PC board. Unfortunately, I think I’m going to have to get a different board since this one isn’t quite
