Blockchain has existed as a concept since the early 1990s, but keeping a distributed ledger for IoT transactions wasn’t widely implemented until IOTA developed Tangle. The blockchain company was initially founded as a hardware startup and pivoted to work on transactional settlement for IoT. The Tangle, their distributed ledger architecture based on a directed acyclic […]
The FPGA revolution that occurred within the past few decades was a boon to many people interested in “antique” electronics. The devices “wire together” logic elements as needed rather than emulating chips completely in a software layer, which makes them uniquely suited for replicating chips that are rare, no longer in production, damaged, or otherwise […]
Look upon this conference badge and kiss your free time goodbye. The 2019 Hackaday Superconference badge is an ECP5 FPGA running a RISC-V core in a Game Boy form factor complete with cartridge slot that is more open than anything we’ve ever seen before: multiple open-source CPU designs were embedded in an open system, developed […]
You ever wonder exactly what’s inside that cheap stuff you get from China? Sometimes it is cheap parts you’ve never heard about. Case in point: if you are willing to import, you can score an FPGA board for about $5. The downside? You’ve probably never heard of the GOWIN Semi GW1N — one of the […]
There was a time when SPARC CPUs were the sole realm of pricey Sun workstations, but now you can put one on an FPGA with just a little trouble. The problem is you need a fairly big CPU which isn’t always cheap unless someone goes out of business and you get lucky. [Ttsiodras] picked up […]
[flow] is a little disillusioned with commercial Data Acquisition Systems (DAQs) and channeled his frustration into his own, very cool, FPGA based solution. The project takes form as a back plane into which various cards can be slotted. The the interface is just a PCI-e connector. If you need analog input, simply insert the card […]
Anyone who’s ever had the pleasure of programming FPGAs knows that it’s a land of proprietary tools that almost require marriage level commitment to a specific platform to be effective. Symbiflow hopes to solve this by becoming the GCC of FPGAs. Rather than a tool built around a specific chip or architecture, Symbiflow will provide […]
Most of the time if you were to want to develop for an FPGA, you might turn to Verilog or VHDL. Both of these are quite capable, but they are also firmly rooted in languages that are old-fashioned by today’s standards. There have been quite a few attempts to treat those languages as an output […]
The Thing is an unassuming name for an ambitious project to build an FPGA board from easy to find components. The project stems from an earlier build submitted to the 2018 Hackaday Prize by [Just4Fun] where two dev boards – an STM32-based Arduino and an Altera MAX II CPLD board – were combined with the […]
While the “M” in MIDI stands for “musical”, it’s possible to use this standard for other things as well. [s-ol] has been working on a VJ setup (mixing video instead of music) using various potentiometer-based hardware and MIDI to interface everything together. After becoming frustrated with drift in the potentiometers, he set out to outfit […]
