My wife and I are headed to Japan for three weeks, roughly one week each in Tokyo/Kyoto/Osaka. As someone who loves to tinker on RPi/Arduino and who appreciates niche/quirky/vintage electronics, where do I need to “pay my respects”? Akihabara is on my radar of course but what shops in particular? The literal shrine to the electronics god in Kyoto is also on my radar.

Today on Geerling Engineering, my Dad and I toured the tower site for WSDZ-AM, located in Belleville, IL. It's a 20kW AM radio station broadcasting with an array of eight individual towers: How does one get a single coherent signal out of an eight-tower array? Enter the phasor: That's phasor with an o, not phaser wi...

After getting many of the PXA16x peripherals working in modern Linux kernels during my Chumby 8 kernel upgrade saga (here are links to parts 1, 2, 3, 4, 5, 6, and 7), I really felt like I was starting to reach the finish line. The display was working well enough to play low-resolution videos, I had basic 2D accelera...

However, when I looked inside a military-grade chip built by Integrated Device Technology (IDT)4 I found a very unexpected layout: over 1500 transistors in an orde...
