When we first saw [Maarten Tromp]’s article about a “momentary latching switch” for guitar effects pedals, we have to admit to being a bit confused. When it comes to push-button switches, “momentary” and “latching” seem to be at odds with each other, with different mechanisms inside the switch to turn one into the other. What gives? […]

There was a time not that long ago when every tool was cordless. But now, cordless power tools have proliferated to the point where the mere thought of using a plain old wrist-twisting screwdriver is enough to trigger a bout of sympathetic repetitive injury. And the only thing worse than that is to discover that

This module is a non-isolated 7A DC-DC converter. The module can convert any DC voltage between 7V to 50V to a 5V DC with load current up to 7A. The project has been designed around LM5116 Wide Range Synchronous Buck Controller IC. The design includes 6uH toroid inductor and two N channel MOSFETS. The operating frequency is 250 KHz. The LM5116 is

Texas Instruments has announced a new IC that is a part of family of ultra-low power, dual channel, resistor programmable temperature switches that enable protection and detection of system thermal events from –40 °C to 125 °C. The TMP390-Q1 offers independent overtemperature (hot) and undertemperature (cold) detection. The trip temperatures (TTRIP) and thermal hysteresis (THYST) options are programmed by
The CHAI team announced at the Open Hardware Summit that the group would be launching an environmental test kit that will be able to work on the Open qPCR machine, which was released in 2016. The kit will be a DIY test kit for COVID-19, which has caused a global pandemic for the detection of the virus on surfaces, objects,
