Thoughts on the unreleased Tangara audio player

A brief analysis of the Kicad source files. Surprisingly uses two 32-bit microcontrollers.

Эпичные подделки HC-06

Я расскажу об актуальной проблеме – а именно, наводнении контрафактом рынка Bluetooth-модулей.
Что, конечно присутствовало всегда, но только сейчас дошло до размаха, когда оригинальные модули HC сталичто угодно, но не BC417. дефицитом.
Так же, познакомлю вас со своим способом изучения китайских подделок, основанным на исследовании и сравнении кристаллов микросхем под металлографическим микроскопом. Готовьтесь лицезреть красоты микроэлектроники. :)

Halloween Projects and Specials

It’s time for our annual reminder that we love Halloween! Our Halloween Project Archives is a great resource for inspiration and ideas.

Halloween is one of our favorite holidays, and … we’ve organized dozens of our Halloween projects into categories: costumes, pumpkins, decor and food.

Summer 2023 – New Products

We’ve released some pretty neat new products this summer! Check them out below:

Our new TFTs are tiny! We added a family of TFTs that are less than 1″ on the diagonal with full color and an optional touchscreen. Find out more on the product pages:

We also introduced a family of 240×320 2″ Transflective TFTTs. Thanks to the transflective technology, these displays are sunlight readable without needing a high powered backlight.

A 3.3v source is sufficient for both logic and backlight power!

A resistive touch version of the 2″ transflective TFT is...

Tiny product update: A new version of the pen holder for AxiDraw, with slots for quick adjustment between the vertical and 45 degree angle positions.

Запуск Тетриса на осциллографе из 90-х

В этой статье я хочу рассказать о том, как я запустил Тетрис на старом цифровом осциллографе. Без пайки и бега по граблям не обошлось... Зачем я это сделал — просто Just for fun.

Free Stuff - August 2023

The August recipient for the Great Scott Gadgets Free Stuff Program is The Factory, a student-run hardware design lab at McGill University in Montreal, Canada. The Factory aims to give students access to advanced tools for their hardware projects, space to work on their projects, and support in developing technical skills.

The Factory has previously offered workshops on VIM, VHDL, C, and PC building. They also run a Hackathon called The Forge. In one instance of The Forge students formed teams and built a line tracing robot to race against the other teams. In non-event related times, students in this lab...

Custom Images on EVE Displays

A frequent question that is received by our support team is how to load custom images on our EVE lineup of displays. Due to differences in the EVE processors between boards and other factors, depending on the display you have, the process may change. The different processes for the boards have been outlined below. The only software required is the handy EVE Asset Builder (EAB) available on Bridgetek’s website here.

The process outlined below is for an SD card loaded with your image. To program an image to the Arduino’s flash memory without the use of an SD...

GSoC23 — Final Project Report

All good things come to an end, and so does my Google Summer of Code (GSoC) project about implementing the SDF INTERCONNECT feature in Icarus Verilog. This feature is important if you want to perform timing accurate Verilog simulations of an ASIC (application-specific integrated circuit). Once a design has been hardened, the delays can be extracted from the actual physical layout, as can be seen in the example of this RISC-V CPU:

PicoRV32 RISC-V CPU...

Moondancer: A Facedancer backend for Cynthion

Note: This is a crosspost of a Cynthion update on Crowd Supply: https://www.crowdsupply.com/great-scott-gadgets/cynthion/updates/moondancer-a-facedancer-backend-for-cynthion

One of the core features promised in the Cynthion announcement is the ability to create your own Low-, Full- or High- speed USB devices using the Facedancer library – even if you don’t have experience with digital-hardware design, HDL or FPGA architecture. If you’ve been eagerly anticipating this feature, we’re pleased to introduce Moondancer, a new Facedancer backend for Cynthion.

Facedancer is a host-side Python library for writing programs that remotely control the physical USB port(s) on Facedancer boards such as the original Facedancer21, GreatFET One, and...
