Conceptually, radar is pretty simple: send out a radio wave and time how long it takes to get back via an echo. However, in practice, there are a number of …read more Continue reading DIY 6 GHZ Pulse Compression Radar
One of the exciting trends in hardware availability is the inexorable move of FPGA boards and modules towards affordability. What was once an eye-watering price is now merely an expensive one, and no doubt in years to come will become a commodity. There’s still an affordability gap at the bottom …read more
[Adam Taylor] always has interesting FPGA posts and his latest is no exception. He wanted to use a Zynq for image processing. Makes sense. You can do the high-speed parallel parts in the FPGA fabric and do higher-level processing on the built-in CPU. The problem is, of course, you need to get the video data into the system. [Adam] elected to use the Mobile Industry Processor Interface (MIPI) Camera Serial Interface Issue 2 (CSI-2).
This high-speed serial interface is optimized for data flowing in one direction. The camera, or the master, sends a number of bits (at least one) serially …read more
Buckle up, buttercup because this is the last weekly Hackaday Links post you’re getting for two weeks. Why? We have a thing next weekend. The Hackaday Superconference is November 11th and 12th (and also the 10th, because there’s a pre-game party), and it’s going to be the best hardware con you’ve ever seen. Don’t have a ticket? Too bad! But we’ll have something for our Internet denizens too.
So, you’re not going to the Hackaday Supercon but you’d like to hang out with like-minded people? GOOD NEWS! Barnes & Noble is having their third annual Mini Maker Faire on November …read more
It was never unusual to have a CPU and an FPGA together. After all, each has different strengths and weaknesses. However, newer devices like the Xilinx Zynq have both a CPU and an FPGA in the same package. That means your design has to span hardware, FPGA configurations, and software. [Mitchell Orsucci] was using a Zynq device on a ArtyZ7-20 board and decided he wanted to use Linux to operate the ARM processor and provide user-space tools to interface with the FPGA and reconfigure it dynamically.
This sounds like a big project and it certainly isn’t trivial by any means. …read more
Years in the making, Apertus has released 25 beta developer kits for AXIOM–their open source digital cinema camera. This isn’t your point-and-shoot digital camera. The original proof of concept from 2013 had a Zynq processor (a Zedboard), a super 35 4K image sensor, and a Nikon F-Mount.
The device today is modular with several options. For example, there is an HDMI output module, but DisplayPort, 4K HDMI, and USB 3.0 options are in development. You can see several sample videos taken with the device, below.
The current device uses a Cmosis CMV12000 image module, although a Kodak KAC12040 and Cmosis …read more
Although we see a lot of MATLAB use in industry and in academia, it isn’t as popular in the hacker community. That’s probably due to the cost. If you’ve ever wondered why companies will pay over $2000 for the base product, you might enjoy the video of a webinar covering using MATLAB and Simulink (a companion product) to program the CPU and FPGA on a Zynq Zedboard. Not interested because of the price? If you aren’t using it for commercial purposes, it isn’t as bad as you think.
MathWorks is one of those companies that likes to market by virtually …read more
Around here we love technology for its own sake. But we have to admit, most people are interested in applications–what can the technology do? Those people often have the best projects. After all, there’s only so many blinking LED projects you can look at before you want something more.
[Landingfield] is interested in astrophotography. He was dismayed at the cost of commercial camera sensors suitable for work like this, so he decided he would create his own. Although he started thinking about it a few years ago, he started earnestly in early 2016.
The project uses a Nikon sensor and …read more

FPGAs are the future, and there’s a chip out there that brings us the future today. I speak, of course, of the Xilinx Zynq, a combination of a high-power ARM A9 processor and a very capable FPGA. Now the Zynq has been made Pynq with a new dev board from Diglent.
The heart of this board, is, of course, the Xilinx Zynq packing a Dual-core AARM Cortex A9 processor and an FPGA with 1.3 Million reconfigurable gates. This is a dev board, though, and with that comes memory and peripherals. To the board, Diglent added 512MB of DDR3 RAM, a …read more
