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 RISC-V microcontroller...

A Q&A with AI regulator Ed Newton-Rex

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 users need to interface an EVE...

Music in the browser or app?

At some point, your inspirational idea for digital music will have to travel from the platonic realm of your thoughts, into either an app or browser. Unless you can luxuriate in doing both, this represents a stark choice.

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 😉️

Die optimale Haussicherung zum Schutz vor Einbrechern – was ist erforderlich?

Die optimale Haussicherung Die Polizei hat alle Hände voll zu tun, denn alle drei Minuten wird in Deutschland in ein Haus oder eine Wohnung eingebrochen. Während den Hausbesitzern in früheren Zeiten nicht viele Sicherheitsmassnahmen zur Verfügung standen, so ist es heute einfacher geworden, entsprechend aufzurüsten, um den Einbrechern das Leben so schwer wie möglich zu […]
