Detecting Unstable Electrical Grid with TinyML
AlexMiller112 Jun 26,2022
IntroductionElectricity is the heart of modern social and economic development. More and more countries strive to transfer to sustainable energy systems, which is quite a challenging process, as it causes increasingly unstable power generation and grid overloads. The unstable electrical grid can endanger people's lives and the safety of their property. This means that power systems should undergo timely monitoring and optimization, which AI and machine learning can easily handle.In fact, artific...

ATF1504-84 DEV Board
SoulCat Jun 26,2022
The Atmel ATF1504 ist a great old CPLD with 5V and/or 3,3V support. The ATF1504-AS is a 5V type.The ATF1504-ASV is a 3,3V type, but it's IO always are 5V tolerant.So you can use both for 5V projects like old 8 Bit computers and so on.The L type is a low power variant of the CPLD (ATF1504-ASL and ATF1504-ASVL).The ATF1504 has 64 Macro Cells and can replace some TTL IC. The small brother is the ARF1502 with 32 Macro Cells. And there is a big brother with 128 Macro Cells (ARF1508).All this var...

C64 PlayOnTape
Lunde Jun 10,2022
Remember waiting around for what sometimes would feel like forever, just to get your favourite game loaded from your trusty datasette? Well, now you can now attempt to return to a slightly less irritating version of those good old days. Loading games will take just as long as they did back then, you just won't need to fiddle with the azimuth setting to get that very specific tape to load. Based on the rather excellent tapuino-project, the C64 PlayOnTape and its accompanying modules is just my ow...
