The first buyer fell through, hit me up if you might be interested!
Hey all! Its unfortunately time to find a new home for my SEM. if you are interested take a look at this doc. TLDR: asking $2,250 OBO, pick up in Santa Clara CA. Other than that its best offer / whoever makes it easiest for me to move it on

I have been locked out of my labsmore.com accounts for the past week due to an expired credit card knocking out my DNS served with AWS route 53. I can't log into my AWS account to fix it since with DNS gone I can't receive a sign in code, or any other email for that matter

A few more photoresist tests. Note these are all way bigger than the "normal" device they represent. Ex: Intel 4003 metal pattern on a 2" wafer
