When I started my ham life as KK6VSI in August of 2015, I wish I could have had the information I'm about to lay out here. Of course, most of the equipment didn't yet exist. So another way of looking at it is that my entry into amateur radio was perfectly timed for my generation's Golden Age of Ham Radio.

setting up a microhydro installation
Have you ever wondered what's inside your Macbook's charger? There's a lot more circuitry crammed into the compact power adapter than you...
I recently bought a cheap Tapo indoor camera to see what my dog gets up to when I am out of the house.
I got a call that on newer hardware some performance regression tests have become slower. Not a big deal. Usually it is a bad configuration somewhere in Windows or some BIOS settings were set to no…
I present to you: The GB Interceptor. It is an adapter that goes between an unmodified Game Boy and the cartridge and offers a video stream of the game via USB. Click the image to see the video on youtube.com. The video above should give you a good overview of what it does, how it works and what its limitations are…
What Chip Weinberger learned building and selling 2500 Jamcorder MIDI recorders.
Apple’s latest line of Macs includes their in-house “M1” system-on-chip, featuring a custom GPU. This poses a problem for those of us in the Asahi Linux project who wish to run Linux on our devices, as this custom Apple GPU has neither public documentation nor open source drivers. Some speculate it might descend from…
Microsoft has deprecated windows 10, yet million of users still use it. They say the hardware is not supported, yet they keep pestering us with endless pings.
Revolutionary Mercedes-Benz drive system developed in Berlin-Marienfelde High-tech manufacturing: 35 processes that are new worldwide and more than 30 patent applications Production across around...
Denver legislators have just passed the first-ever agricultural Right to Repair bill. Today’s landslide 44-16 vote in the House follows successful votes in the Senate last month.
While I knew about and even tried various very early attempts to run macOS on non-Apple hardware, it wasn’t until early 2020 that I’ve built my first proper one. Then I built several more which are still seeing daily use.
Apple announced the new Mac mini with the all-new M6 and powerful M5 Pro, delivering a dramatic boost in performance and more versatility in its supersmall desktop design.
One of the remarkable characteristics of the Super Nintendo was the ability for game cartridges (cart) to pack more than instructions and assets into ROM chips. If we open and look at the PCBs, we can find inside things like the CIC copy protection chip, SRAM, and even "enhancement processors".
Earlier this year, I blogged about work I did to improve VRAM management for games. Now, after many months of floating around in mailing lists, the kernel patches are finally merged upstream and queued for Linux 7.3! Hooray!
When Alex and I were pitching SoundFocus as an app that helped people with hearing loss, this was often…
The global memory crunch and the great repricing of consumer electronics
The U.S. taking an equity stake in Intel is a terrible idea; it also happens to be the least bad idea to make Intel Foundry viable.
Zhengbang ZB3245 review. We bought a Zhengbang Pick & Place machine and this page tells you all about our experience of setting up and using.
Researchers at MIT and Princeton have found a way to increase the output of silicon solar cells by allowing a single photon to release two electrons in the silicon.
At COMPUTEX 2023, NVIDIA announced NVIDIA DGX GH200, which marks another breakthrough in GPU-accelerated computing to power the most demanding giant AI workloads.
It took a while, but I finally managed to create my own Game Boy cartridge. With WiFi! At this point, it can only demo a simple telnet-style communication and access Wikipedia articles, but I am confident that I will showcase more in the future. For now, the interesting and surprisingly tricky part is how the thing…
If you’re new to this series, I’ve been documenting the process I went through upgrading my old PXA166-based Chumby 8’s 2.6.28 Linux kernel to a modern 6.x version. Here are links to parts 1 , 2 , 3 , 4 , 5 , 6 , 7 , and 8 . At this point in the project, all of the main hardware peripherals were working great. I…
