Collaborate Disseminate
When Pano Logic went out of business in 2012, their line of unique FPGA-based thin clients suddenly became a burden that IT departments didn’t want anything to do with. New and used units flooded the second-hand market, and for a while you could pick these interesting gadgets up for not …read more
Microcontrollers are small, no one is arguing that. On a silicon wafer the size of a grain of rice, you can connect a GPS tracker to the Internet. Put that in a package, and you can put the Internet of Things into something the size of a postage stamp. There’s one microcontroller that’s smaller than all the others. It’s the ATtiny10, and its brethren the ATtiny4, 5, and 9. It comes in an SOT-23-6 package, a size that’s more often seen in packages for single transistors. It’s not very capable, but it is very small. It’s also very weird, with …read more

While trying to revive a Donkey Kong Jr arcade board, [Jelmer Bruijn] found himself in the market for an EPROM programmer and became the proud owner of a 1990’s era Dataman S4. Despite its age, it’s a fairly nice tool which allows you to read and write a laundry list of different EPROM types, all without being tied to a computer. The only catch is that a few types of chips need an adapter to work in the Dataman S4, some of which are unsurprisingly no longer available.
After some above and beyond support from the current crew at Dataman …read more

We’ve got a small box of microcontroller programmers on our desktop. AVR, PIC, and ARM, or at least the STMicro version of ARM. Why? Some program faster, some debug better, some have nicer cables, and others, well, we’re just sentimental about. Don’t judge.
[Dmitry Grinberg], on the other hand, is searching for the One Ring. Or at least the One Ring for ARM microcontrollers. You see, while all ARM chips have the same core, and thus the same SWD debugging interface, they all write to flash differently. So if you do ARM development with offerings from different chip vendors, you …read more

If there was one downside to 8-bit computers like the Commodore 64, it’s that they weren’t exactly portable. Even ignoring their physical size, the power requirements would likely have required a prohibitively large power bank of some sort to lug around as well. The problem of portability has been solved since the late ’70s, but if you still want that 8-bit goodness in a more modern package you’ll have to look at something like retrocomputing madman [Jack Eisenmann]’s DUO Travel computer.
The computer is based around the ubiquitous ATmega328 which should make the ease at which it is programmable apparent. …read more
Turning an Arduino of virtually any sort into a simple AVR 6-pin ISP programmer is old hat. But when Atmel came out with a series of really tiny AVR chips, the ATtiny10 and friends with only six pins total, they needed a new programming standard. Enter TPI (tiny programming interface), and exit all of your previously useful DIY AVR programmers.
[Kimio Kosaka] wrote a dual-purpose TPI and ISP firmware for the ATmegaxxUn chips that are used as a USB-serial bridge on the Unos, and constitute the only chip on board a Leonardo or Micro. The catch? You’re going to have …read more
