If poetry is your thing, this hack might convince you that your brain is more advanced than the rest of us poor sots. [Roni Brandini] designed a system that prints lines of poetry when you concentrate. The Mind Poetry project uses an EEG headset from Mattel’s Mindflex toy and pipes your brain’s signals to an Arduino […]
https://www.wiringo.com/electrical-connector-everything-you-need-to-know.html Cloom, a reliable wire harness, and cable assemblies manufacturer, today published an “Electrical connectoe–Everything You Need to Know.” It has four chapters that cover some useful terms about Electrical connector knowledge. The publication is available here for free. This guide sheds insightful light on these electrical connector properties. “The Cloom R&D team adapts quickly

Remember the old video game Space Invaders? Some of its sound effects were provided by a chip called the 76477 Complex Sound Generation chip. While the sound effects1 produced by this 1978 chip seem primitive today, it was used in many video games, pinball games. But what’s inside this chip and how does it work

You’re in a crowded street with many high buildings around you and you find your car position on Google maps is wrong. That’s usual, right? This is caused from (fake/distorted) GPS signals reflected from the high buildings around you which make your GPS receiver do some wrong calculations. So be careful don’t always listen to

Fitting transmit and receive capabilities of radio signals into one device may be impossible without using a significant filter, which is needed to isolate sent and received signals from each other. The major obstacle to achieve that is the weakness of the received signal compared with the much stronger transmitted signal. However, researchers from Cornell
I have a $500 Rigol DP832 programmable triple-output power supply sitting on my bench, yet I built a 5V regulator to sit atop a 9V battery for some reason. Perhaps it’s more portable, or cheap enough to toss in with the rest of the project it is powering, or maybe the bench power supply is
In electronics, a device is said to be a latching device if it maintains any particular fixed state even after removal of the input signal. The same also applies for electronic/electromechanical relays. Basically the electromechanical relays that are used today are of two types: 1. Non-Latching Relay : These relays are most widely used where
I bought a couple of IXYS linear MOSFETs (IXTK90N25L2) a while ago to test their capabilities when used as electronic load, and the result was quite impressive. So I decided to build another electronic load using both MOSFETs. As you can see in the video towards the end, this electronic load can sink more than

DDC’s HSN-1000 radiation-hardened Hybrid Nuclear Event Detector (NED) senses ionizing radiation pulses generated by a nuclear event, such as the detonation of a nuclear weapon, and rapidly switches its output from the normal high state to a low state with a propagation delay time of less than 20ns. The active low Nuclear Event Detection signal
