OPENISA LAUNCHES FREE RISC-V VEGABOARD

RISC architecture is gonna change everything, and I still can’t tell if we like that movie ironically or not. Nevertheless, RISC-V chips are coming onto the market, chipmakers seem really interested in not paying licensing fees, and new hard drives are shipping with RISC-V cores. The latest development in Open instruction sets chips comes from OpenISA. They’ve developed the VEGAboard, a dev board with two R ...

OPEN SOURCE BIOLOGICAL GEAR FOR THE MASSES

At the risk of putting too fine a point on it, Hackaday exists because people are out there building and documenting open source gadgets. If the person who built a particular gizmo is willing to show the world how they did it, consider us interested. Since you’re reading this, we’ll assume you are as well. Over the years, this mentality has been spreading out from the relatively niche hacker community into ...

HOW TO TIME DRONE RACES WITHOUT TRANSPONDERS

Drone racing is nifty as heck, and a need all races share is a way to track lap times. One way to do it is to use transponders attached to each racer, and use a receiver unit of some kind to clock them as they pass by. People have rolled their own transponder designs with some success, but the next step is ditching add-on transponders entirely, and that’s exactly what the Delta 5 Race Timer project does. Th ...

Line Frequency Meter Based On Reciprocal Counting

Precise measurement of line signal frequency is very important in many applications, especially in the management of power grid systems. Tasks like calibration of governors of engines that run generators in power plants need a resolution up to 0.01Hz. Frequency is also an important parameter in load sharing among several power plants in the grid. Presented here is a line frequency meter, that does it for yo ...

Who killed the Quark?

Intel is phasing out its lightweight Quark processors, with final orders wrapping up this summer, and shipments ending in 2022. The Quark suffered from growing competition from high-end MCUs and low-end Cortex-A7 chips and the lack of a clear market focus. When we read in AnandTech recently that Intel was discontinuing its Quark CPUs, the news was so unsurprising we almost decided to skip it. But perhaps it ...

RGB Color Detector Using TCS3200 Sensor Module

This is a simple Color Detector using Arduino Uno R3 and TCS3200 color sensor module. It can be useful for color identification and detection for food-processing units, color printer applications, paint-mixing applications and other industrial applications including robotics. This project is used for detecting primary colors (red, green and blue, or RGB)—colors that are physically available in LEDs in one p ...

TINY CHEAP ARM BOARDS GET WIFI

Over the last few years, we’ve seen the value of putting tiny WIFi-enabled microcontrollers on a module that costs a dollar or two. Those smart light bulbs in your house probably have an ESP8266 in them, and you can build a WiFi-enabled anything with one of these chips for next to no money. Now there’s a new module that takes the design philosophy of, ‘a reasonably powerful microcontroller, on a module, tha ...

ARDUINO AND THE OTHER KIND OF HOMEBREW

Usually, when we are talking about homebrew around here, we mean building your own equipment. However, most other people probably mean brewing beer, something that’s become increasingly popular as one goes from microbreweries to home kitchen breweries. People have been making beer for centuries so you can imagine it doesn’t take sophisticated equipment, but a little automation can go a long way to making it ...
