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…
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.…
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.…
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…
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
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…
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…
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…
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…
two ears. two channels.
Double the circuit for stereo. This is a breadboard representation of a single “channel.” Each channel will have its separate PCB with controls.…
