I attended the Community Connections Night for the Electrical and Computer Engineering department last night. The students set up maybe 10 different stands to pitch their projects and highlight some of their student organizations. I’ve been volunteering with this group for almost 10 years now. In these 10 years, I’ve only seen maybe 1 or… Read More
New year, new vulnerabilities Reading the latest vulnerability report of the ESP32-C3 and C6, quite a popular chip these days, made me think about how to respond to such news. If you are an OEM, it might be “glad I don’t use the ESP32” or if you do it’s “OMG, what happened.” But really, neither… Read More

It was fun chatting with Stacey on why an embedded security engineer is an important, but often missing role on design… Read More
I occasionally get asked where one can buy a CryptoCape. It had a good run at SparkFun and its distributors for awhile, but alas, it is retired. However, the project limps on now at OSH Park, where you can order the PCBs!

I gave a short talk at the Open Source Hardware Summit last week on Digital Ownership and Right to Repair. (Link to slides (pdf) and youtube). It was a different kind of talk for me–I tried to pick a topic, in this case Right to Repair, and unpack it from different angles. As with most… Read More
SparkFun posted a blog post on IoT Security. While posting to a blog isn’t newsworthy (unless it’s the one you are currently reading 🙂 ), I’m very encouraged to see this post at SparkFun. The makers/engineers building projects/products are the front line–a systems security engineer like me is combat support. I had a small excerpt… Read More

The new Cryptotronix slogan is Crypto for Makers. It passed the board meeting with an unanimous vote1. I think it better represents my main focus with Cryptotronix which is to make cool crypto stuff. Plus, I’ve used it twice for two different presentations, one time at my local hackerspace and once at SparkFun2. There are… Read More
