Mi homemade potentiostat is becoming a mess with the batteries and their new connections. Now I have to change one of the amplifiers, I'm using a 741 as placeholder but it generates too much noise.

Estos días me he sentido vacío, sin propósito.
Entiendo que el sentido de la vida es un artificio que edificamos muchas veces según nos acomode, pero no parece haber una receta fácil para hacerlo.
Intento retomar las cosas que me gustan, proyectos del pasado y del futuro, pero todo parece demasiado insignificante para mis entrañas.

Something weird is going on right now, and I’m not sure I like it.

Certain social media managers are asking me questions about the Fediverse. That means they’re preparing for the moment an exodus from Twitter becomes real.

I've been sick for the last year. I have this feeling that my body can't autoregulate as it should.
I sometimes wonder if the doctors actually know what's happening, I wouldn't get mad if they don't, but their overconfidence always bothers me.

My "vacations" start today, more like a temporal change in the priority of my projects, but I'll try relax a little bit anyway.

After a week of work, lots of head scratching, I've managed to draw all these different-looking menus, with a single #uxn file that is shared by these different projects.

The menu drawing code has no actual drawing code, but instead uses each app's own string drawing routines.

The program "anoise" goes well with some animated GIFs as wallpapers, the sound also helps me to relax and focus as I work.

This is a cyclic voltammetry for glucose biosensor. I'm comparing the signals obtained with a precision instrument and a homemade one. Sadly it won't reach the fast speeds of the real thing, but I can still use my instrument to measure glucose concentration in certain solutions.

I'm trying to build a potentiostat for cyclic voltammetry, it seems it requires further calibration but at least my signals (red) are similar to those expected (blue)
