The above shows my home-built digital clock. It uses Nixie-tubes for readout. In contrast to most other nixie-clocks being built these days, my clock does not use any transistor or IC for driving the tubes. Instead, the driving logic is built from neon lamps , together with resistors, capacitors and silicon diodes.

Introduction In my last post, I discussed the process of building my Magic Leap One (ML1) view simulator model (hereafter referred to as “model”), and now I would like to show you what the view of …
The title of this review was carefully chosen, not glibly. I want what is best for VR and all other technologies on the Reality–Virtuality Continuum, Magic Leap included. Unfortunately, their cur…

Some integrated circuits have very interesting dies under a microscope, like the chip below with designs that look kind of like butterflies....
Electronics, Embedded Systems, and Software are my breakfast, lunch, and dinner.
The SN76489 is the same sound chip as found in the SEGA Master System. This is an array of eight SN76489 sound chips playable via USB...
Do you want to get into tinkering and hacking Bluetooth LE devices? Up until now, doing so was very much a DIY process. You would h...
A decade ago, we entered the current era of notebook design when Steve Jobs pulled the future out of an envelope.
At the end of December, Apple made good on the release of the new iMac Pro and started selling and shipping the new workstations. While this could be characterized as a stop-gap effort until the ne…
Towards the end of last year, I got a new laptop: the Purism Librem 13. It replaced the Lenovo ThinkPad X250 that I was using previously, which maxed out at 8 GB RAM and was beginning to be unusabl…

I build and maintain smf - the fastest RPC in the west.The main language supported is C++. We use Seastar asthe actual asynchronous framework.
The main feature is fast access to a flat, 24-bit address space. Although there are many ways to retrofit a 'C02 with expanded memory, AFAIK none can touch this implementation for speed. Given any random address in the 16 megabyte space, KK can fetch that byte in 6-8 cyles. It's fast because:
