“A PID controlled DIY reflow hotplate using an Aluminium PCB to solder SMD components Story : Last time I made a reflow soldering hotplate from a regular clothing iron. And it works pretty great. The only issue is it uses mains …
“Control two LEDs with IR Remote, IR Receiver and Arduino. This project shows how to control two LEDs with IR Receiver and Arduino. An Infrared (IR) transmitter uses light to transmit signals to the IR receiver. The light is in …
“Stress and strain, applied in just the right manner, can sometimes produce amazing results. That is what researchers, led by a team at UC Berkeley’s Department of Electrical Engineering and Computer Sciences, discovered about an emerging semiconductor material — black …
“Zinc-based batteries are promising options for energy storage devices owing to their low cost and high energy density. However, they may encounter serious dendrite issues, especially at high areal capacities and current densities. Recently, a research team led by Prof …
“In 1998, the journal Nature published a seminal letter concluding that a mysterious signal, which had been recently discovered analysing the polarization of sunlight, implies that the solar chromosphere (a very important layer of the solar atmosphere) is practically unmagnetised …
“I recently did a PC power supply teardown so I figured it would be interesting to go deeper and see what happens inside the power supply’s control IC. The die photo below shows the UC3842 chip, which was very …
“An exotic form of magnetism has been discovered and linked to an equally exotic type of electrons, according to scientists who analyzed a new crystal in which they appear at the National Institute of Standards and Technology (NIST). The magnetism …
““SensiCut,” a smart material-sensing platform for laser cutters, can differentiate between 30 materials commonly found in makerspaces and workshops. With the addition of computers, laser cutters have rapidly become a relatively simple and powerful tool, with software controlling shiny machinery …
“Quantum matter can be solid and fluid at the same time – a situation known as supersolidity. Researchers led by Francesca Ferlaino have now created for the first time this fascinating property along two dimensions. They now report in the journal …
“- I modified DOSBox to extract the frequency/delay value pairs of the Monkey Island PC-Speaker songs. - I then used Huffman compression to squeeze all music inside an ATtiny85 (512 bytes of RAM, 8 KB of flash) - Once I managed …
