LFO modulated simple VCF
this is a rough draft of a circuit i’ve been working on based of the Simple VCF circuit floating out there. a big thanks to the original author for that.

solid-state tremolo for tube amps…
i’ve have a CBS-era Fender Bantam Bass in for repair that looks like a bowl of spaghetti inside the chassis. it’s a slew of yellow wire spread from one side
simple LFO circuits…
i was reading over this thread on diystompboxes.com about building an analog LFO circuit for some wild noise idea i’ve got brewing in the back of my head. i started
TDA2040-based amp schematic with EQ…
well here’s the first draft of the simplest medium powered solid state design i could muster. TL082 can easily be substituted with a TL072 which is probably better anyhow (i
TDA2040 Instrument Amplifier
the need for small and portable amplifiers has arisen mainly by a desire to come up with some sort of all-purpose busking amplifier. here is the first screen shot of
SCHEMATIC: TL082 9V Active EQ…
an experimental EQ circuit based of the TL082 datasheet. i modified it to use a 9V battery, but could probably still use some work in terms of efficiency… as most
SPICE: ngSpice plot test…
nothing too special here. i’ve been practicing my SPICE skills and attempting to work with a single-supply active EQ circuit based on the TL082. further research of this chip has
Mellotronium revised…
here’s an update on the new additions/approach to the Mellotronium. i’m attempting to redo the SD card routines once i get the functionality added. using the SD library just doesn’t
