One of the key concepts in electronics is the printed circuit board (PCB). A printed circuit board (PCB) mechanically supports and electrically connects electrical or electronic components using conductive tracks. Simplest PCBs have only insulation board with copper traces on one side. More complicated PCB is sort of like a layer cake or lasagna- there →
Cheapest Linux-capable computers are very cheap – just few dollars. “These processors are nearly cheap enough to give away.” So this embedded developer got an idea of making a barebones Linux board in a business card form factor. We have seen electronic business cards before, with various fun features including emulating USB flash drives, blinkenlights, →
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 →
