I finished proofreading the blog post on my webpage: http://davbucci.chez-alice.fr/index.php?argument=elettronica/gem_s2/gem_s2.inc I hope you'll enjoy! #Turbokit #GEM #Generalmusic #S2 #S3 #electronics #diy #synthdiy

By the way, I managed to have the Ramdisk working reliably. Look at that whopping 2048KB free! #turbokit #GEM #S2 #Generalmusic

I wrote a (lengthy) article for my blog about the #GEM #S2 #Turbokit. I still have to proofread it, so it is still a little rough around the edges, but if you want to give a peek here it is: http://davbucci.chez-alice.fr/index.php?argument=elettronica/gem_s2/gem_s2.inc #music #homepage #blog #generalmusic #electronics #DIYelectronics #diy #diysynth

Big win! I installed the #Turbokit on the #GEM #S2 and after some fiddling IT WORKS! I waited this moment since 1996 🥰 The #PCB was correct and the components were perfect, but it took a while to fix all the bad solder joints. Gosh, those 0402x8 resistor networks are SMALL and it took a while to learn to solder them properly (hot air and flux are your friends). Now, I only have to install the NiMh battery in a safe way. #electronics #sinthdiy #diy #music #Generalmusic #S3

I received a few days ago the 4-layer board I designed for the #Generalmusic #S2 #Turbokit replica. It looks very nice, let’s hope it works 🙂 I will assemble it in the next few weeks, then I will try to install it on my keyboard.

In the meanwhile, I sent the order both for the components that remain to be sourced and the PCB. Now, I just have to wait. #Turbokit #Generalmusic

Btw I received today this book that has been written by one of the members of the group who developed the #Generalmusic #S2. It is very interesting and full of details and interesting anecdotes about this Italian #synth. M. Colò, R. Gerbi “GEM S2, Quello che non sai… raccontato dai protagonisti”. It does not cost much and it id really interesting.

I corrected some errors and I think I reached what I think it will be the v1.0 design of the #PCB. I hope it will work! #Generalmusic #Turbokit #electronics #DIY #Synth

I'm not very experienced with the routing of a 4-layer PCB but it is fun. The different copper layers are starting to look nice! #Turbokit #Generalmusic #Electronics #Diy

I created a GitHub project for the #Turbokit replica for the #Generalmusic #S2. It is not a project for the faint of heart, however, at it will require to modify the original boards of the #synth. It is still pretty much an ongoing project: https://github.com/DarwinNE/GEM_turbokit #openhardware #electronics #diy
