50 Ohm impedance became the standard impedance used in RF transmission lines long ago, but it is still useful today and is a standard reference impedance used in test equipment.
After viewing our CGA Redux livestream a friendly tinkerer named Arek contacted me if I was interested in a homebrew Hercules Graphics Card PCB that he designed. Naturally I said yes and assembled the card, playing beta tester for his design. It will probably be open sourced eventually, but is not yet available. So…
I’d like to share with you my latest project: Decktility!
How SiliWiz helps you get an understanding of how semiconductors work and are manufactured
In another thrilling adventure with ChatGPT, I endeavored to integrate it with a Raspberry Pi, effectively turning it into my own personal light switch. My custom ChatGPT plugin, sporting just two ...
Intel investigated architectural enhancements and modifications for a 64-bit mode-only architecture.
In 2020, we initiated the Meta Training and Inference Accelerator (MTIA) family of chips to support our evolving AI workloads, starting with an inference accelerator ASIC for deep learning recommendation models (DLRMs).
A blog by and for database architects.
I was wondering what the IBM Personal Computer would have been like if they had chosen the Motorola 68000 instead of the Intel 8088, so I used my MCL86+ to emulate the 68000 and find out! The MCL86…
I have set up an electronics lab bench for all my hobby and product development projects. In this article, I will dive deep into every part of the setup and guide you through the structure, organiz…
Two systems I know pretty well, Apache BookKeeper and Apache Kafka, were designed in the era of the spinning disk, the hard-drive or HDD. Hard-drives are good at sequential IO but not so good at random IO because of the relatively high seek times. No wonder then that both Kafka and BookKeeper were d
Apps introduce powerful features designed for iPad to deliver the ultimate mobile studio for video and music creators.
Request to Google : ungrey the “OEM unlocking” toggle in the factory, before shipping store.google.com devices to customers. Do not make your customers connect the device to the Internet before they are allowed to install the operating system they want.
The problem with enforcing TPMs on consumers
In a fun-filled deep dive into a Philip's Hue Color light bulb, I disassembled, analyzed, and ultimately restored it to working order. Over the course of the hack, I dismantled the bulb’s interior,...
The objective for this project was to implement a UDP transmitter for use on the RP2040 that would consume zero CPU time. The system described on this webpage is implemented with 3 PIO state machines, 12 DMA channels, and 1 PWM channel. It generates an NLP, performs packet checksum calculations, and performs packet…
Let’s start at the beginning. What is an FPGA ? Well, FPGA stands for F ield P rogrammable G ate Array , which isn’t helpful in understanding what they are or do but we had to get that out of the way.
In the very beginning, there was … well, this thing. The OKTO35 Mk1. A machine that could (barely) shoot and scan its own 35mm film movies.
The goal here is to grab power from external battery packs of varying voltages and supply power to 'desktop replacement' sized laptops. This same topology can be used for Dell barrel jack systems.
I wanted to get a music streaming server running as I have in the past but with the scarcity of RasberryPi’s my I needed to try something new. I had a Samsung Galaxy S7 that had been taking up space in my junk drawer and this post is my journey to give it a new task.
We generally know that when we buy a piece of technology that it will not last forever, connectors wear out and/or go out of fashion. But I think the most frustrating reason to have to get rid of something is that drivers stop being made for devices.
We are proud to announce that starting the firmware version 0.82, your Flipper Zero's battery life will last up to 1 month! It took us 2 years to resolve all firmware issues that prevented Flipper Zero from switching to power-saving mode, resulting in the same power consumption baseline in

How I received the signal of MANY satellites with an RTL-SDR V3
I like Sun Ray laptops. They make surprisingly useful thin clients. Here, going from right to left, I'm playing Quake on my Solaris UltraBoo...
Nitrokey security research reveals that smartphones with Qualcomm chips secretly send device data to Qualcomm without user consent. NitroPhone is not affected.
