Feature description The INRIKS EX4076KVM is a transmitter and receiver kit that allows HDMI and USB signals to be transmitted over twisted-pair cables for up to 230 feet. Specsheet claims the maximum supported video resolution is 4K at 60 Hz. The transmitter...
The idea for this project occurred to me while I was implementing the PC Joystick adapter for #Control Freak , and the user @Dave's Dev Lab mentioned that he had 300 IBM PC jr joysticks and I started to wonder if I could use the cheap Digispark...
As noted in our previous column, in the not-so-distant future we’re going to start creating simple circuits using resistors and light-emitting diodes (LEDs), but we first need to learn enough about resistors to ensure we use the right ones when the occasion...
Let's get to some more real-world examples. First, we can look at a color-pill. Pick a color. If you search for "blue pill" or "green pill" or "red pill" and tac "stm32" on to the search, they all bring up useful information. ...
I bought a device that harbors a Mini ITX mainboard (Intel D410PT(B)). It also had a power supply failure, so we're left wondering whether that in turn damaged the mainboard as well. First off, this is a no-fix, but maybe you'll enjoy the story of the...
Let’s look inside a COB LED strip (and what is it anyway?) 1. Introduction. LEDs for the LED strip2. Samples of COB strips3. Removing the phosphor from the COB strip4. Blue light5. Damage to the individual LED chips and the effect on the operation of...
First of all, you should pay attention to the ROM used. The flash-ROM chip from an old computer motherboard has a finicky parallel interface where the address is written in two runs. This complicates the operating logic and increases access time. Additionally,...
Introduction I've been diving in to forth on and off for a while now. It's a thing that takes over my whole brain, and I really welcome the distraction from time to time. And it's for my work, so there's that. I've been bouncing...
Introduction of Service Robot Fundamentals of Service Robot As a kind of semi-autonomous or fully self-help robot, service robots are able to perform useful service work for human beings, such as carrying, cleaning, and rescue. As service robots...
Part one. Basic functionality If you drive a car, it's very likely that you've come across an uncomfortable situation involving a cyclist at least once or twice in your life. Bikes can be quite unpredictable on the road and you often have to guess what...
Over the past 10 years, we have witnessed the active development of the VR industry and efforts to implement it in various business and entertainment sectors. It quickly evolved from an exotic, incomprehensible, and very expensive novelty to a common...
In 2021, the global electronic manufacturing services (EMS) market size was valued at $500.26 billion, which is expected to grow at $849.72 billion in 2028 with a CAGR of 7.9%. The whole market grows rapidly which is driven by industries like...
See current entries: sci-fi-contest tagEntry Deadline: 12:00:00am PDT on 4/29/14Let’s face it… you want an excuse to build something cool. In addition to the notoriety of winning a Hackaday contest, we have a number of very respectable prizes this...
Long ago, in a land called Kettering, OH, my 14-year-old self got bored, restless and discontent, but this was no ordinary case of adolescent ennui. I was jealous, longing, consumed by the desire to do one thing above all else. It was a crazy...
It seems like most HackADay projects involve Arduinos, in their various forms. I view Arduino as a gateway drug: it lets people start experimenting with micro controllers, but you will (probably) soon outgrow them. My first micro controller project,...
