Implementing Neural Networks on the “10-cent” RISC-V MCU without Multiplier

I have been meaning for a while to establish a setup to implement neural network based algorithms on smaller microcontrollers. After reviewing existing solutions, I felt there is no solution that I really felt comfortable with. One obvious issue is that often flexibility is traded for overhead. As always, for a really optimized solution you have to roll your own. So I did. You can find the project here and a detailed writeup here.

It is always easier to work with a clear challenge: I picked the CH32V003 as my target platform. This is the smallest...

Setting Up Your EVE Display: A Quick Guide

Have you just purchased one of our Embedded Video Engine (EVE) displays and are wondering how to get up and running? This blog post aims to help users get started with their newly received EVE displays from setting up the hardware to running various demos.

Before we jump in, if you have not already, take a moment to read our blog post on FTDI/Bridgetek Embedded Video Engine (EVE) Modules to get an idea of the various functionalities that the EVE makes possible and what makes them so great!

This section outlines how to interface an EVE display with...

Gradual migration of IP address/port between servers

I'm a strong proponent of self-hosting all your services, if not on your own hardware than at least on dedicated rented hardware. For IT nerds of my generation, this has been the norm sicne the early 1990s: If you wante to run your own webserver/mailserver/... back then, the only way was to self-host.

So over the last 30 years, I've always been running a fleet of machines, some my own hardware colocated, and during the past ~18 years also some rented dedicated "root servers". They run a plethora of services for either my personal stuff (like this blog, or my personal email server),...

KLayout and the Sky130 PDK

KLayout and Sky130: Inverter

I have created a small example of how to use KLayout for the layout of a simple inverter and run DRC and LVS for Sky130 in the hopes that it helps others on a similar journey.

You can find the repository with all files and a description in the klayout-sky130-inverter repository.

There are still some issues with the KLayout technology files so make sure to read the workarounds!

Good Luck 😉️

March Update: Making waves

Long awaited community update is here! Introducing PineVox and bone conduction headset (help us find a name!), IronOS progress, PineNote insights, and PineTime news! We also cover cluster failure, state of services, and the future of the community updates. See you in the upcoming Q&A!

SDR приемник GPS на микроконтроллере

В этой статье я расскажу о том, как я делал самодельный SDR GPS приемник на микроконтроллере. SDR в данном случае означает, что приемник не содержит готовых GPS‑модулей или специализированных микросхем для обработки GPS сигналов — вся обработка «сырых» данных (от АЦП) выполняется в реальном времени на микроконтроллере (STM32 или ESP32)

Зачем я это сделал — просто Just for fun, плюс — получение опыта.

Cynthion Has Passed EMC and Tycho Has Shipped to Our Manufacturer

Note: This is a crosspost of a Cynthion update on Crowd Supply: https://www.crowdsupply.com/great-scott-gadgets/cynthion/updates/cynthion-has-passed-emc-and-tycho-has-shipped-to-our-manufacturer

The title says it all! Cynthion has passed EMC testing which means it is ready for manufacturing and Tycho, our Cynthion-testing quality assurance rig, has been shipped to our manufacturer. Our next steps are to work closely with our manufacturer to create final product samples, ensure the QA process is achieving the results we expect at factory level, and receive the final product samples and test them in-house here at Great Scott Gadgets. We’ll have more for you soon!
