I have a blog now! Like an old school long form one! Been meaning to set one up forever and then never got around to it until now. Starting with something small, a little teardown of a cheap Color E-Ink Android tablet: timonsku.zip/bigme-b6-e-i...

Bigme B6 E-Ink Tablet teardown

For another project I was interested in looking at cheap E-Ink Android tablets and landed on the Bigme B6 Color. A 6" color E-Ink tablet with a 1072x1448 resolution screen. The black and white portion...

My huge beautiful company is so important but also needs more money or it will collapse and die as it is weak and frail but changing the world. Please help me I am so powerful and strong and my company is so good, but also it needs more money than anything else ever has, for reasons of some sort

Yeah I need way more money than anyone ever got before. I need it because my shit is difficult right now. But it's important in ways even I haven't been able to work out. OpenAI is a serious business. Help me. Please help me please my serious company is so good. Help me www.cnbc.com/2024/12/27/o...

In 1994, a math professor discovered that Intel's Pentium chip sometimes gave the wrong answer when dividing. Fixing this "FDIV" bug cost Intel $475 million. I analyzed the Pentium chip and found the bug. 1/N

This is the final 200 Glasgow shipment for the original Crowd Supply pre-order batch! This finalizes the Crowd Supply campaign! It took a lot of time and effort to get here. Thank you everyone for you trust and patience!

Four brown boxes with white labels. The labels indicate they contain Glasgows. Each box contains 50 Glasgows.

Call for SPI flashes at #38C3 I'm developing some SPI-flash tools and want to try a variety of devices and flash chips for testing. Got devices where it's tricky to dump in-system or rare flash chips? I'd love to test them at #38c3 if you can bring them!

This was one of my most popular tweets, I think mostly due to the clear macro photo I took. Footprint was P0.5mm vs 0.65mm. So IC couldn't be soldered down. I was able to bodge existing boards in 1-2hrs. While my friend spent 10min on the redesign (+waiting a week for mfg/ship).

Hi đź‘‹ I'm Greg, hardware engineer. I enjoy designing and building open source hardware projects. along with taking macro photos to document the process. Previously at a startup I used FPGAs and thermal LWIR cameras to map bushfires from aircraft Currently doing RISC-V ASIC things at IQonIC Works
