mecrisp-ice on my iCEBreaker FPGA board. So cool. The first time synthesizing my own Forth CPU.
Thanks to Matthias for the Mecrisp project.

What do we know about the Gowin GW5A #FPGA (GW5AT-LV60P484A) found on the Tang Console?
Board pricing looks reasonable, but I'm naturally concerned about open-source support. I did see some discussion at Project Apicula last year: https://github.com/YosysHQ/apicula

This is so hard 2h of your life you should spent watching the story of SUPERSEGA. DO IT! Thx to @slopesgameroom for putting this together! #game #games #gaming #retro #retrogaming #supersega #sega #fpga #superspga https://youtu.be/_Qhsfh7CeYE
So, hamwa also geschafft:
– den #FPGA für die #Tomographie-Reko zumindest gebootet
– aber noch nicht drauf eingeloggt
– das 3D-Röntgenmikroskop von Kegelstrahl (hohe Auflösung) auf Parallelstrahl (hoher Durchsatz) umgebaut
– anjustiert
– den neuen #FPGA für die Triggerpulse eingebunden
Jetzt können die Doktorandys mal bisschen justieren, ich fahre kurz nach Göttingen zur Plakettenzereominie¹, heute Abend mitm Chef zurück.

Schon lange her :), further testing of our #fpga mic array. ddr finally works properly and now testing filters 
Me he mudado de instancia y no he hecho aún la #presentación... Qué mastodonte estoy hecho. Al lío.
Me llamo Luis, soy ingeniero electrónico y estoy especializado en #FPGA. Antes para espacio, ahora en criptografía.
Me gustan el #rock y el #metal y soy batería aficionado, aunque hace bastante que no practico.
Soy especialmente fan de la #fantasía en libros, series y películas.
Eso, y un poco de política, es lo que encontrarás en mi perfil.
Woot another 4 voices built and tested (simple saw tooth filter sweep).
Bottom to top ;
- Alchitry AU fpga
- 4 vcf/vca voice card
- another 4 vcf/vca card
- STM32 card for midi and patch storage
- Alchitry BR to give me access to pins
The whole thing consumes about 450mA so far but the FPGA isn’t doing much yet, just generating a sawtooth and 32 delta-sigma DACs for the audio and CVs.
