- Comment on Making a PCB, using solder mask as etch resist. 7 months ago:
Adding solder mask is an optional step. If you use an etch resist like toner or dry film, you have a functional PCB even without solder mask. The solder mask is the unnecessary step that can be skipped.
Using solder mask as an etch resist, you would have to scrape away the remaining mask in areas where you want exposed pads - you would either need another mask for this, or to manually scrape each pad, adding an unnecessary step.

Speaking of Contra - there is a new Contra out March 12, 2024 (today! or tomorrow depending on timezone), Contra: Operation Galuga. I haven’t played the game yet, but the trailer looks amazing!

The animation with the C:\ prompt is great! I hadn’t seen this before, but that’s one of the all-time greatest game openings!
- Comment on At what size of transistor does semiconductor manufacturing become practical for independent manufacture? 1 year ago:
Sam Zeloof (sam.zeloof.xyz) has been working in the area of DIY semiconductor fabrication, and has successfully fabricated working ICs (from 6 - 100 transistors). He’s done an incredible job at reaching ~1970’s technology levels in a home lab.
Another example of DIY fabrication: hackaday.com/…/jeri-makes-integrated-circuits/ Jeri Ellsworth made her own silicon inverter.
These examples are still very small-scale compared to even simple microprocessors, etc - but it’s fascinating to see this level of technology becoming more accessible.
