Want a fast PWM quickly? – consider Arduino
I have been discussing control algorithms for a power supply and idly looking for some easy hardware on which to try the technique – hardware small enough to build into a prototype. My default tends to be to 8bit PICs, but someone in the discussion pointed to the ATtiny25/45/85 family as a source of PWM …
Weller doesn’t seem to make it easy
After many years of loyal service, my Weller TCP 24 soldering iron needs a new bit – I think Pb-free solder has got the better of it. So I thought I would get help choosing a new bit from Weller’s website. Now, and it is probably me rather than Weller, I can’t find anything that …
EW test – micro:bit might lead to frustration
EW called for volunteers who have never coded to run through the first exercise in the micro:bit guide for children – the Don’t steal… exercise. There are no children in Electronics Weekly Towers, so an adult bravely stepped up. She has experience writing web pages in HTML, but none in any programming language. And, having …
Blackest coating now sprayable
Vantablack, the world’s blackest material, from Surrey NanoSystems, no longer has to be placed by chemical vapour deposition (CVD) as it can now be sprayed on. It is based on carbon naontubes. “Called Vantablack S-VIS, the spray paint greatly widens the applications potential, making it possible to coat much larger and more complex shapes and structures, as …
Microchip’s Xpress eval board
I have been struggling to find any details of the MPLab Xpress Evaluation Board that Microchip is promoting alongside its new web-based version of its MPLAB integrated development environment. Apart from it having a PIC16F18855 on-board. But I did get sent a close-up photo of it, so I though I would stick it here. Done. By …
Great zero-gravity video
Wise Steve K has contacted the blog with a link to an amazing video, filmed in zero gravity, with no camera tricks or CGI. Here it is, and it is well worth a look – I am so impressed with the organisation and talent of these people. US radio station NPR – think Radio 4 …
Learn from a shrimp that communicates with polarisation
Mantis shrimp communicate using the polarisation of light through polarising reflectors. “Most eavesdroppers can’t see this type of light information and so animals that use it are less likely to attract the attention of predators or unwelcomed competition” said the University of Bristol. According to the University, using a combination of anatomy, light measurements and …
