Epiq Solutions, a company from the USA, has included a new member of its Sidekiq line of Software-defined radio (SDR) add-on cards called the Sidekiq Z2. Dimensions of this card are only 51 x 30 x 5mm, the size of a full-size mini-PCIe card, the Sidekiq Z2 computer-on-module is advertised as “the world’s smallest wideband RF transceiver + Linux computer […]
A team of researchers from National Renewable Energy Laboratory (NREL) has discovered a new method for developing a rechargeable non-aqueous magnesium-metal battery. A proof-of-concept paper published in Nature Chemistry. It described how the scientists pioneered a method to enable the reversible chemistry of magnesium metal in the noncorrosive carbonate-based electrolytes and tested the concept in
Disclaimer: The circuit in use here came from GreatScott: YouTube video related to this project: https://www.youtube.com/watch?v=Fj0XuYiE7HU Thanks for the circuit GreatScott, it really works well! The awesome find of the lipo protection chip with 2.9v cutoff – ruined way too many cells with the DW01’s 2.5v! So, down to business: We all know the frustration of

We once saw a Romeo and Juliet production where the two families were modern-day mob families with 3-piece suits and pistols. If they made King Richard III set in this week, the famous line might be: “Hand sanitizer, hand sanitizer, my kingdom for hand sanitizer!” Even if you have a supply stashed in your prepper

Rk Clean Air is a gas responded device that is capable of monitoring gas leakage, smoke, and carbon monoxide leakage in the home. According to the National Fire Protection Association, “Three of every five home fire deaths resulted from fires in homes with no smoke alarms (38%) or no working smoke alarms (21%) and the death rate

Economy of scale is a wonderful thing, take the switch-mode power supply as an example. Before the rise of the PC, a decent multi-voltage, high current power supply would be pretty expensive. But PCs have meant cheap supplies and sometimes even free as you gut old PCs found in the dumpster. [OneMarcFifty] decided to make a
What’s up my friends, welcome back. What I want, is the aluminum block below to have let’s say, exactly 100 degrees. I’ll control the real temperature using a K type thermocouple. To read the data I’ll use the MAX66 75 breakout module and control the PID algorithm with and Arduino. Finally, to apply power we
Over the weekend the official Arduino Day 2020 livestream took place providing oversight of what you can expect from the Arduino platform in the near future. If you are unable to attend to catch up on the news will be pleased to know the stream is now available via YouTube view at your leisure. Check

Unless you happen to be from Finland, this is just an all too familiar situation: you’re stuck in an inescapable situation with this one person who is really more of an acquaintance than a friend, and neither of you knows who should say something in hopes of keeping a conversation going. Awkward silence is inevitable,

Just when we think we’ve peeped all the cool baby keebs out there, another think comes along. This bad boy built by [andyclymer] can be configured three different ways, depending on what kind of control you’re after. As designed, the PCB can be used as a six-switch macro keyboard, or a rotary encoder with two switches,
