Our chips look the best, no competition!

Mountain View Reverse Engineering (mtvre) meetup tonight 7 pm at Wagon Wheel BBQ! Talks: -Jacob C on“Unlocking an Encrypted Zip” (30 min) [email protected] on "Raspberry Pi reverse engineering" (30 min)

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

Almost sold out of current Maasi spin coater inventory! Starting the next run to raise the current production from 14 to somewhere in the 20 to 24 range

Mountain View Reverse Engineering (mtvre) meetup TONIGHT, 7:00 at Wagon Wheel BBQ. See you there!

Mountain View Reverse Engineering (mtvre) meetup this Wed, 7:00 at Wagon Wheel BBQ. See you then!

Successfully printed a Maasi spin coater "vase" (fluid bucket) in polypropylene! This will ease concerns more aggressive solvents / photo-resists will dissolve conventional print materials

Want to learn about DIY / FOSS silicon fabrication? Check out FOSSF Silicon at Frontier Tower today to see an open source hardware toolchain! We'll be running live demos exposing and developing wafers

Don't mind me, just grabbing coffee with my lithography machine

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

Halfway decent result doing large feature lithography with laser printer transparency

Great seeing everyone at Open Sauce! If you're interested to contribute to FOSS silicon manufacturing by testing tools exhibited here (Maasi spin coater, Hacker Fab stepper, etc) please reach out!

Come find us at open sauce to get commemorative wafers!!

Check out FOSSF Silicon at Open Sauce this weekend! We're showing off the FOSS semiconductor design + fabrication ecosystem including a Hacker Fab stepper, tube furnace, Maasi spin coater, prototype devices, and much more! Booth C.18

come see me at Open Sauce this weekend in San Mateo! i will have the MOnSter 6502 on display! this is the world's largest 6502 microprocessor, built out of discrete transistors. it will be set up at CuriousMarc's booth.

Tried to pattern a wafer today with a Hacker Fab stepper. Didn't quite work but hopefully I'll have another go before open sauce

I'll be at OpenSauce 2025 along with @curiousmarc.bsky.social, @tubetime.bsky.social, and Mike. We plan to show some Apollo hardware, atomic clocks, vintage avionics, and who knows what else, so stop by if you're attending. opensauce.com

Mountain View Reverse Engineering (mtvre) tonight 7 PM at Wagon Wheel BBQ. Talks: -Adam on: “Behind the Badge: How we used and abused hardware to make the 2024/2025 Aerospace Village Badge” (40 min) -Possibly a second one

Tried to print a Maasi FOSS spin coater polypropylene (PP) liquid catch "vase" but PP is a notoriously difficult material. Anyone have a smooth workflow (ex: filament brands) that I could try to replicate?

Great having Jacob Lagerros over at the McLab! RIP his credit card in the name of chip decapping science to feed the hungry microscopes

Mountain View Reverse Engineering (mtvre) meetup Wed July 9th, 7 PM at Wagon Wheel BBQ. See you there!

I'd like to rebrand siliconpr0n.org to siliconprawn.org as I work with more academics. Looking for help with art assets if you'd be interested to contribute something!

Great seeing iFixit at Teardown conference!

60,000:1 CMOS inverter scale model - now with magnets! Get his little brother at the @tinytapeout.com store: store.tinytapeout.com/products/Sky... #ASIC #CMOS

Mountain View Reverse Engineering (mtvre) meetup tonight! 7:00 at Wagon Wheel BBQ. Talks: - Joshua on: "OFDM gems (or: The Unreasonable Effectiveness of the Fourier Transform)", ~40 min - Thomas and Ford on "80s computers worked by accident", 15 min

Making wafer contacts with Edmond and Alessandra! The gold sputter contacts worked great (~30 ohm) but the silver epoxy ones were bad (~1M ohm)

I like using a rough sandpaper on the copper because you get a more matte surface finish vs shiny. It really doesn't scan well when its shiny, example:

This is tonight 6 pm at the Santa Clara Marriott. See you soon!

Mountain View Reverse Engineering (mtvre) is having a special meet up in collaboration with hardwear.io tomorrow Thursday May 29! We'll have a few short talks: -Ethan on Kia infotainment hacking -Keith on the Pippin (presented on a Pippin!)

Using veo3 to build my microscope empire. Didn't quite work like I hoped (wanted laser beams shooting out of the objectives). Maybe I'll just have to build this now IRL? I think I might have all of the parts needed already

Listed some Maasi spin coater kits for sale! Decided on eBay to keep friction low for now. Please spread the word and LMK if there's something you'd love to see in a future kit! www.ebay.com/itm/2361249...

youtube.com/shorts/lwu0... Maasi FOSS spin coaters getting assembled for distribution. Interested? DMs are open!

Anyone use Intel's 386 processor from 1985, the first 32-bit x86? To improve performance, it preloaded instructions into a 16-byte prefetch queue (highlighted in red). Why does such a small queue take up so much of the chip? Let's look under the microscope at its complicated circuitry... 1/N
