I am making a thing. A “polyphonic” (three note) MIDI to CV adapter. Its super old school strip board construction. The image is of the display/control board and the microcontroller MIDI board. The CV, gate and trigger board is under construction.

I am using an AT Mega 328P as the microcontroller. Three MCP22008s for the 7 segment displays and to drive the gate and trigger transistors. And a bunch of MCP4822 dual DACs feeding in to TL07x OpAmps for the CV outputs.

For pitch and pitch bend I am using two channels via differential amplifiers to provide a -4V to 4V, volt per octave range. Everything else is 0-4V.

The UI allows you to set OMNI mode or midi channel, octave adjust and polyphony on or off. It uses a first available scheme (like the Jupiter 6).

It has MIDI in (naturally), Thru and Out. Out is like Thru but is just the common or unhandled messages. This means you can cascade (out in to in on a second converter) to support more than three notes.

Ahoy!

We will be operating ADSL, VDSL and GPON services at EMF in a limited trial area in Camping C2.

You can even wholesale your own service over the top!

#emfcamp #emfcamp2026

Scientists have crossed the DNA of a crab with a cheetah.

They had to cancel the project because things went sideways *real* fast.

Passing on an invitation from my other half who is not currently engaged in Fediversal things: would anyone going to #emfcamp be interested in an informal session to learn about knitting a mitred square blanket? Also generally chatting about knitting?

Pictured is an example of how this type of blanket can come out; it's really good for using up little bits of yarn. She'll bring a few spare sets of double point needles and some yarn but feel free to bring yours also, the more the merrier :)

Hey folks! Please pass this training on to those in the UK South West you think will find it useful.

Inspired by 404: Deadname Not Found, this beginner workshop for trans people focuses on online safety, your rights to your data and digital footprint and how to limit, find and remove sensitive personal information that could put you at risk.

Delivered by transgender, non-binary and cisgender facilitators that work in Privacy, Security and Safety online with experience in intersections of gender identity alongside race, ethnicity and online activism. We’ll also cover basic and accessible cyber security and online privacy, threat modelling, secure and insecure communication methods, as well as looking at international travel as marginalised identities under threat.

We want to make preparing for uncertain times as easy and approachable as possible.

This is a relaxed introductory session and there will be time to socialise and ask questions afterwards. Booking is essential email us for a booking link and put Digital Self Defence in your subject line.
