The $12 Gongkai Phone
Recently, I paid $ 12 at Mingtong Digital Mall for a complete phone, featuring quad-band GSM, Bluetooth, MP3 playback, and an OLED display plus keypad for the UI. Simple, but functional; nothing compared to a smartphone, but useful if you’re going out and worried about getting your primary phone wet or stolen.

Hacking together a USB-C charger for a cheap Chromebook
The era of USB-C has come. The other day I threw all other cables into a box, and bought a set of USB-C to USB-C, Lightning, and microUSB cables. USB-C chargers around the house, USB-C PD power bank, even a nice small USB-C dock that works with the Nintendo Switch if the charger can do the right voltage. It's glorious.

Most of my retro computing interest revolves around networking, and I wanted something that could natively attach to modern Wifi networks without the need to maintain an old linksys router just for my retro computers. There are many ways to do this, I…

Testing Microsoft's Windows Dev Kit 2023
Last week Microsoft started selling their $599 Windows Dev Kit 2023, formerly known as 'Project Volterra'. I got my hands on one after a little bit of a shipping delay, and promptly started tearing it down to see what's inside. You can click here to browse the entire Twitter thread where I posted pictures of the box…

The Apple III was pitched as an evolution of that platform, but was clearly doomed due to hardware and software issues. The Lisa was expensive and not…

Unsung Beauty of Analog Devices Datasheets
Engineers build stuff. They need to put together complex systems, most often from pieces that others have built. I jokingly talk to my colleagues that software engineering is similar to plumbing - take various pieces of software and link them through an interface (API or in case of real plumbing - connectors,

64bit computing on a budget
With all that Dec Alpha talk , and how hard it is to get hardware, and how seemingly exclusionary it is, I thought I would try to touch on a more available 64bit ‘risc’ platform, for the masses!
