BeagleWire: fully open ICE40 FPGA BeagleBone cape

BeagleWire by Michael Welling is a fully open ICE40 FPGA BeagleBone cape:

BeagleWire: fully open ICE40 FPGA BeagleBone cape

BeagleWire is a completely open source FPGA development board. Unlike most other FPGA dev boards, the BeagleWire’s hardware, software, and FPGA toolchain are completely open source. The BeagleWire is a Beaglebone compatible cape leveraging the Lattice iCE40HX FPGA.

BeagleWire can be easily expanded by adding additional external modules for example, modules for high speed data acquisition, software defined radio, and advanced control applications. Using well-known connectors like Pmod and Grove makes it possible to connect various interesting external modules widely available in stores. Owing to this, prototyping new imaginative digital designs is easier.

iceRadio SDR project

Software Defined Radio (SDR) project by Eric Brombaugh:

iceRadio

This is a test prototype for experimenting with Software Defined Radio (SDR). It is composed of several boards that are described in detail elsewhere on this site:

VHF Tuner – 20MHz – 1200MHz VHF/UHF downconverter.

RXADC Board – 40MSPS 14-bit ADC for capturing HF-band RF signals.

STM32F303 and ice5 Board – MCU and FPGA which implement the digital receiver.

I2S DAC PMOD – Used for stereo audio output of demodulated signals.

Combined with suitable firmware and FPGA design, these boards comprise a receiver capable of capturing 20kHz of signal from DC to over 1GHz, demodulating it with a variety of formats and driving high-quality audio.

Tuner

RF input from the antenna can optionally be tuned down from VHF/UHF frequncies to an IF frequency in the HF range before passing to the ADC.

ADC

Raw HF or downconverted VHF at an IF of 5MHz is digitized to 14-bit resolution. The maximum input signal allowed without exceeing the range of the ADC puts the 0dBfs point of this system at -10dBm in 50 ohms. The ADC runs at 40MSPS with a resolution of 10 bits, providing approximately 60dB of dynamic range and 20MHz of bandwidth which places the quantization noise floor at about -70dBm.

FPGA

From the ADC, data passes into the FPGA. This is an iCE5LP4k part which provides 20 4kb RAM blocks and 4 16×16 MAC blocks which are essential for the DSP required for the downconversion. In the FPGA the ADC data is pre-processed to a sample rate appropriate for the MCU. Figure 2 below shows the primary components of the FPGA design.

The C and Verilog source code is available on GitHub:

Hackaday Prize Entry: PaperBack Desktop ePaper Monitor

When we announced the Hackaday Prize with its Best Product category, [PK] polled his wife and co-workers about the idea of making a desktop monitor using 6″ 800×600 ePaper, which he has since built and calls the PaperBack. One such requirement for a monitor is to be able to connect to it using one of…

The Road from AXIOM Beta Developer Kit to Production Camera

From Sebastian of the Apertus Open Source Cinema Camera project:

The Road from AXIOM Beta Developer Kit to Production Camera

Developer Kits have been shipping for some time now and we are aware that the most pressing question for many of you is “When will the AXIOM Beta evolve from a Developer Kit to being a production ready camera?” This article should help to answer that question, but keep in mind that the camera has been carefully designed to evolve constantly.

Game Gear HDMI with SNES Controller

From Bryan Cockfield on the Hackaday log:

Game Gear HDMI with SNES Controller

With its backlit color screen and Master System compatibility, the Game Gear was years ahead of its main competition. The major downside was that it tore through alkaline batteries quickly, and for that reason the cheaper but less equipped Game Boy was still able to compete. Since we live in the future, however, the Game Gear has received new life with many modifications that address its shortcomings, including this latest one that adds an HDMI output.

Here is a video of it in action:

Very early prototype using my GBA HDMI board to get a 1280x720p output from the Game Gear.

The custom PCB uses a Spartan6 FPGA to convert the Game Gear’s 160×144 12-bit RGB video into a 1280x720p HDMI output using a 4x integer scale. HDMI video is generated directly from the FPGA, audio is taken from the Game Gear’s headphone jack.

It has some pixel glitches, but it could be due to the wiring as it’s very sensitive to positioning. The Game Gear was bought as a “broken” unit and is in need of a cap replacement, that could also be causing issues.

OSH Park sponsors the FOSSi Foundation
