The Making of a Minimalist Analog Drum Machine
Our hacker [Moritz Klein] shows us how to make a minimalist analog drum machine. If you want the gory details check out the video embedded blow and there is a first class write-up available as a 78 page PDF manual too. Indeed it has been a while since we have seen a project which was this well documented.
A typical drum machine will have many buttons and LEDs and is usually implemented with a microcontroller. In this project [Moritz] eschews that complexity and comes up with an analog solution using a few integrated circuits, LEDs, and buttons.
The heart of the build are the integrated circuits which include two TL074 quad op amps, a TL072 dual op amp, a CD4520 binary counter, and eight CD4015 shift registers. Fifteen switches and buttons are used along with seven LEDs. And speaking of LEDs, our hacker [Moritz] seems to have an LED schematic symbol tattooed to his hand, and we don’t know about you, but this screams credibility to us! 😀
This capable drum machine includes a bunch of features, including: 4 independent channels with one-button step input/removal; up to 16 steps per channel; optional half-time mode per channel; two synchronizable analog low-frequency oscillators (LFOs) for dynamic accents; resistor-DAC output for pitch or decay modulation; and an internal clock with 16th, 8th, and quarter note outputs, which can be synchronized with external gear.
Of course at Hackaday we’ve seen plenty of drum machines before. If you’re interested in drum machines you might also like to check out Rope Core Drum Machine and Shapeshifter – An Open Source Drum Machine.

@tfb it was! And I was so surprised!

Dopo 16 anni passati con noi la mia piccola Margot questa sera ha passato il Ponte dell'Arcobaleno.
Ciao piccola pazza, grazie di tutto il tempo passato assieme.

@DarioZanette ah per quello, MAMiL come se piovesse, tra l'altro odiati da pedoni ed altri ciclisti urbani tanto quanto dagli automobilisti.

GIORNATA DI ARTIVISMO
Domenica 22 marzo, dalle 14:30 alle 23:00, presso LOCK - Laboratorio Occupato Kasciavìt, Via San Faustino 62, Milano
UNA GIORNATA DI ARTIVISMO
🗓️ (questa) Domenica 22 marzo dalle 14:30 alle 23
📍@collettivo_kasciavit - Via S. Faustino 62 - in occasione del Mercato Lockale
Dove siamo? Come stiamo? Cosa desideriamo?
Come rete di Artivismo ci siamo posti queste e altre domande per creare insieme una giornata dedicata all’Arte resistente dove condividere pratiche e parlare di espressione, dissenso creativo, utopie e immaginazione.
Nel corso del pomeriggio, fino a tarda sera, si alterneranno reti, collettivi e artistə che abitano le arti con valenza politica: dalla fotografia al fumetto, dal rap all’electropunk, dal teatro alla poesia.
✨ Con Andrea Bellaroto · Apollineo · ArT* Festival · Casa per la Pace · Freevan · Hurricane Ivan · Inmotulus · Kamera Lab · Mattia L. · Nebüla · No Kings Milano · RAVE OVER · Rete No CPR · Rocks Against Fascism · Scate · Tempi DiVersi · Timidoceleste · Una Finestra Sbagliata
🍽️ Fermati a cena! Troverai un apertivo/cena vegan per smangiucchiare tutto il pomeriggio, a sostegno delle spese dellə artistə e dei collettivi presenti.
Ti aspettiamo!

@crc i can't find description of Pali on your site.
nevermind, this language is pretty straightforward. i would read sequences of insructions like "lisuli" and interpret them as phrases.

@RnDanger @tess that's a good idea, «How much care goes into avoiding strain on the affected part.» as a gauge of the pain (at least where possible, so not for teeth abscesses, probably, but now that you make me think about it it's probably why I decided to go get an Xray of the wrist when I fell down skating).

I have the following set in my .kshrc to do exactly that.
