It is pretty easy to do soldering ….Apply some flux, Heat the surface and apply solder .But when it comes to soldering SMD components it requires a little bit of skill and some tools and accessories. Industries use re-flow ovens with temperature profile Control to mass produce circuit boards. If you don’t have re-flow oven, →
To introduce a kid to electronics I ordered DIY NE555 Electronic Organ Teaching Kit kit from Banggood (cost around 3 Euros). They sell also many other similar kits, but this seemed to be good quality at decent price (around 3 Euro). There was not much information on the product page other than product picture, circuit →
https://hackaday.com/2019/11/15/needling-your-projects-3d-printed-pcb-probing-jig-uses-accupuncture-needles/ Trying to probe a modern electronic circuit with tiny SMD components, without letting the magic smoke escape in the process, can be quite a challenge. [Giuseppe Finizia] solved this problem with a 3D printed PCB probing jigthat uses acupuncture needles. [Jonathon Oxer] from the YouTube channel SuperHouse did a very nice video on the →
There has been questions like those on 2600 magazine Facebook group: How do you prevent your phone from being used as a bug so malicious individuals can spy on you? What’s the best way to temporarily block/disable the microphones in an iPhone. Does anyone know of a phone case with a built-in shutter? The idea →
There has been for several years talking that nanotube transistors are coming to use and they can be better than traditional transistors made of silicon. I see this news as a major milestone. IEEE Spectrum writes: https://spectrum.ieee.org/nanoclast/semiconductors/processors/modern-microprocessor-built-using-carbon-nanotubes Engineers at MIT and Analog Devices have created the first fully-programmable 16-bit carbon nanotube microprocessor RV16X-NANO. It’s the →
https://spectrum.ieee.org/energywise/semiconductors/optoelectronics/acpowered-leds-could-cut-the-cost-of-lighting “Engineers at Pennsylvania State University have demonstrated a practical way to integrate gallium nitride LEDs and their power supply circuits onto the same chip using industry-standard manufacturing processes.” The results promise a cheap lighting chip that runs directly from the AC electricity supplied by a wall outlet (110-120V AC). Researchers say that this makes →
