> You may have seen Debra Ansell’s sound-reactive LED embroidered party dress. Or her internet-connected, intelligent edge-lit acrylic light paintings. Or you may have recreated one of her builds yourself – following the instructions she generously puts up on her site geekmomprojects.com. Alternatively, you may recognise the name because almost everyone we speak to nowadays cites her as an influence on their work. We spent an hour with her talking about everything from manufacturing, creativity, and how you get from a physics PhD program to teaching kids electronics.
> BIGTREETECH has unveiled a compact board equipped with a 64-bit Allwinner H616 processor. Additionally, the company is offering a compatible PI4B adapter which gives access to one LAN port, dual Micro HDMI ports, one USB Type-C and other standard peripherals.
> At its core, the Internet is really just a bunch of computers networked together. There’s no reason that there can’t be other separate networks of computers, or that we all have to tie every computer we have to The One Internet To Rule Them All. In fact, for a lot of embedded systems, it doesn’t make much sense to give them a full network stack and Cat6e Ethernet just to report a few details about themselves. Enter LoRaWAN, a wireless LAN that uses extremely low power for Internet-of-Things devices, and an implementation of one of these networks in an urban environment.
> One of the main reasons the Commodore 64 became an icon of the 1980s was its MOS 6581 “SID” sound chip that gave it audio capabilities well beyond those of other microcomputers of the 8-bit era. The SID became something of a legend by itself among chiptune enthusiasts, and several electronic instruments have been designed that generate their sound through a SID chip. Not many of those look anything like traditional musical instruments however, so we’re delighted to see [Linus Åkesson]’s new project: two Commodore 64s joined back-to-back using a bellows to form a wonderful new instrument called the Commodordion. It can be played in a similar way one plays a traditional accordion: melodies are played with the right hand, chords with the left, and volume is adjusted by varying the pressure in the bellows.
