Improvements to Cynthion Hardware
Note: This is a crosspost of a Cynthion update on Crowd Supply: https://www.crowdsupply.com/great-scott-gadgets/cynthion/updates/improvements-to-cynthion-hardware
Since our last hardware design update in April, we have been hard at work refining the Cynthion design in preparation for production. Believe it or not, we’ve completed and tested six design revisions since r0.6 described in April!
In r0.7 we increased the maximum pass-through current by selecting FETs with lower resistance and by improving heat dissipation of the PCB layout. We added filters to the buttons, reducing the need for debouncing in firmware and gateware. We added a zero ohm series resistor to the oscillator so that it...
Новая жизнь старого GPS-приёмника
В этой статье я расскажу о том, как я использовал старый GPS-приемник в качестве приёмника для захвата "сырых" данных GPS. Также я постараюсь рассказать о базовых принципах приема и декодирования данных GPS.

Nexperia’s app note on their load switches, combining multiple load switch functions in to one chip. Link here (PDF)
Nexperia load switch ICs are highly integrated Power Management Integrated Circuits (PMICs) designed to efficiently control power rails within electronic systems. Load switches serve as indispensable components for managing power distribution and enabling the smooth operation of various loads.
Thoughts on the unreleased Tangara audio player
A brief analysis of the Kicad source files. Surprisingly uses two 32-bit microcontrollers.
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:
Displays New Small TFTsOur 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:
Tiny Capacitive Touchscreen Display 80×160 Small Full-Color TFT DisplayWe 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...

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.

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.
Images from SD CardThe 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...
