THine Raspberry Pi camera extension kit works with 20-meter LAN cables

Most applications using Raspberry Pi camera are perfectly happy to rely on the FPC flat cable connecting the Pi camera to a Raspberry Pi SBC. But for some use cases, the board and camera may have to be separated by some distance, for example, if you’d like to keep the single board computer indoor, while the camera is housed in a waterproof enclosure outside. THine Solutions has designed a cable extension kit for the Raspberry Pi camera exactly for this purpose. The kit comes with Rx and Tx boards to be connected to the board and camera respectively., as well as a 2-meter CAT5e LAN cable, but the company says the solution supports up to 20-meter Ethernet cables. THine camera extension kit content and key features: Supported cameras – Raspberry Pi camera V1.3 (for certain modes only), Raspberry Pi camera V2, and Raspberry Pi HQ camera Tx Board – Transmitter […]

PiccoloSDR – A Raspberry Pi Pico powered SDR working with GNU Radio

There’s a lot you can do with the tiny Raspberry Pi Pico board, but computer student and radio amateur Luigi Cruz decided to go a step further by making Raspberry Pico RP2040 board work as an SDR compatible with GNU Radio open-source toolkit. The PicoSDR PiccoloSDR project relies on one of the ADC pins from the Raspberry Pi Pico board to sample 8-bit data at around 500 ksps and makes the data available through TCP/IP (emulated via the RNDIS protocol) over the Full Speed USB interface at up to 12 Mbps. As Luis notes applications are limited due to the low bandwidth, but it’s still a fun project. You can see demos with a web-based tone generator, a PWM generator, and actual audio where we see the spectrum chart, scope plot, and FFT plot updated in real-time. He has not released the demo code “officially” just yet, but I can […]

Crowbits Master Kit Review – Part 1: A first look at the ESP32 based education kit

Crowbits STEM education kits comprised of magnetic modules launched on Kickstarter a couple of weeks ago. There are five kits increasing in difficulty with the Hello Kit just requiring the student to connect modules to get started, i.e. no programming required, to the Crowbits Master Kit based on a battery-powered ESP32 module suitable to create your own phone, portable game console, radar tower, etc… Elecrow sent me the latter for evaluation, and in the first part of the review, I’ll unbox the kit, see how modules mechanically fit together, and have a quick look at the user manual, before trying one or two projects from the manual in the second part. This is the second STEAM product from Elecrow that I review, as I reviewed CrowPi2 Raspberry Pi 4 laptop last year. Let’s open the package. We have a total of six modules with two joysticks, an ESP32 module with […]

Xilinx open sources Vitis HLS FPGA tool (Front-end only)

While there are some open-source programs for FPGA development such as Symbiflow or Yosys, FPGA vendors usually only provide closed-source programs for developers wanting to work on their chips. But Xilinx has recently made a move to fulfill its “commitment to supporting open-source initiatives for developers and researchers” with the release of the source code of Vitis HLS Front-End. What is Vitis HLS exactly? Before we look at the source code release, we may want to know what Vitis HLS does exactly. The company describes it as a high-level synthesis (HLS) tool that allows C, C++, and OpenCL functions to become hardwired onto the device logic fabric and RAM/DSP blocks. It implements hardware kernels in the Vitis application acceleration development flow, and to use C/C++ code for developing RTL IP for FPGA designs in the company’s Vivado Design Suite. Vitis HLS design flow goes as follows: Compile, simulate, and debug […]
