MacroFAB FX Development Board is an Open source Audio Electronics Prototyping Platform (Crowdfunding)

A couple of years ago, I wrote about a Linux multi-effects guitar pedal, and if you are interested in such audio projects, another company called MacroFab, specializing in manufacturing & assembling PCBs & electronic device, has now designed open source FX development board for audio electronics prototyping, that can be used for audio effects “guitar” pedals, and let you design your own tones. Key features of FX development board: Potentiometers 9V battery holder ¼” Input and output jacks connected to breadboard True bypass 3PDT switch User selectable power supply connections Dual solderless breadboards with power rails selectable by jumpers Adjustable 9 V power supply Power supply with 2.1 mm dc input jack for use with AC-to-AC wall wart; +/- 15 volt @ 200 mA power supplies with over-current protection; +1.25 to 9 V @ 150 mA adjustable power supply; Split voltage rail (1/2*9 Volt Rail) @ 15 mA for use […]

SonikTech e-Paper Shield Starter Kit Relies on Teensy LC MCU Board

Soniktek Electronics has designed the “e-Paper Shield Starter Kit” featuring Pervasive Displays’ E2215CS062 e-paper screen, and an adapter board to connect it to Teensy LC (Low Cost) board powered by NXP Kinetis L ARM Cortex M0+ microcontroller @ 48 MHz, or other 3.3V MCU boards supporting SPI. Adapter board & display specifications: Supports Pervasive Displays 2.15″ E2215CS062 e-paper screen with 208 x 112 resolution, no backlight required, fully sunlight-readable Communication protocol – SPI @ 3.3V Sensor – On-board thermometer with I2C interface Dimensions – Screen: 48 mm x 26 mm; adapter board fits into Teensy-LC module (36x18mm) The advantages of e-Paper display are that they don’t require power to maintain an image, and they can be read in sunlight, just like actual paper. I can’t remember having seen many – if any – low cost e-Paper development kits so far, and the project is open source hardware with design files and […]

$24 Winkel Arduino Compatible Board Includes WiFi, Bluetooth, 2.4 GHz RF, and an RTC (Crowdfunding)

There are plenty of Arduino compatible boards with WiFi based on ESP8266 WiSoC going for around $5 to $10, and with ESP32 processor, we are starting to have $15 to $20 boards with both WiFi and Bluetooth, but while ESP-IDF SDK has been progressing nicely, some parts of Bluetooth functionality are still not implemented. Winkel board offers an interesting alternative by offering WiFi, Bluetooth, 2.4GHz ISM, and an RTC for $24. Winkel board specifications: MCU – Microchip/Atmel ATmega128 MCU @ 16 MHz with 128KB flash memory, 4KB SRAM, 4KB EEPROM Connectivity WiFi 802.11 b/g/n via ESP12E module based on ESP8266 Bluetooth 2.0 + EDR via HC-05 module RF Radio – NRF24l01 2.4 GHz ISM radio. (Note: It might be possible to use it for Bluetooth LE connection, see here and there). I/Os (through both Atmel MCU and ESP8266) 38x Digital I/Os 7x PWM Digital I/Os 8x Analog Inputs USB – […]

OnChip Open-V Open Source 32-bit RISC-V Processor Launched on CrowdSupply

Open source hardware gives mostly full control over software and hardware, but there are different levels of openess, with some companies wrongly claiming their product to be open source hardware – with a nice accompanying logo – once they dump some source code somewhere and publish the PDF schematics, while others are doing it right with the release of schematics and PCB layout in source format, as well as software and proper documentation. However even for the latter group, the actual chips are closed source bought directly from silicon vendors or their distributors. So the good news is that you now have the opportunity to bring the meaning of open source hardware to a whole new level thanks to OnChip Open-V 32-bit processor that is open source, and getting launched on Crowd Supply crowdfunding platform. OnChip Open-V is based on RISC-V (pronounced “risk-five”), comes with peripherals, and should be competitive […]
