Chris and Elecia chat with each other about motor encoder reading methods, conferences coming up, soldering irons, schematic reviews, looking for a new job, and general life.
Some conferences coming up in the embedded space:
Embedded Online, April 29-May 4, virtual (Elecia will be speaking)
Open Hardware Summit in May 3-4, Montreal, Canada
Embedded World in April 9-11 in Nuremburg, Germany
Evil Mad Scientist Laboratories was purchased by Bantam Tools!
Starter soldering irons? It seemed like small pen-style ones were more popular than big soldering stations. See the Adafruit USB C Powered Soldering Iron - Adjustable Temperature Pen-Style - TS80P. Or for much less (but you can write your own firmware!), the Pinecil. And one vote for the RT Soldering Pen on Tindie because it uses Weller RT tips (which are more expensive than the soldering pen but much less expensive than the Weller station that uses the RT tips).
Embedded Artistry has excellent advice for the role of the firmware in schematic reviews.
Adafruit Playgrounds looks like a neat place to write up your project.

We spoke with ecologist Dr. Meredith Palmer and embedded engineer Akiba about lions, terror, and technology. Akiba works for FreakLabs.org on global conservation projects. We talked about their Boombox which Meredith uses to create experiments to map the landscape of fear in predator/prey relationships. While this may look like pranking animals with jump scares, well, there is real science being done. What would it look like to be smooched by a lioness? ( Video ) Bird hears lion, decides to go over there ( Video ) Checking the reflexes of some zebras and other critters ( Video ) These are lots of fun to watch and you can find the freshest ones and help out science by categorizing some at Snapshot Safari . Or skip to using the data on Lila.science ( Snapshot Safari 2024 data ). Check out Meredith’s website for more github and Data Dryad links to data and science. If you want to get involved, Wildlabs.net has discussions around conservation technology. There is also a Slack group by Sara Beery focusing on AI for conservation.

Elecia’s journaling notebook is this one on JetPens (which is where she gets her nice pens and some of her stickers and washi tape). From discussing some listener messages, we mentioned: Matt Keeter’s talk on debuggability in production where you don’t have access to the system that is faulting ( video and slides ) Letter boards (in the Adirondacks), see those in action here Wokwi simulator is a great place to get more embedded experience without buying all the kits. Christopher has said that there will not, definitely not, under any circumstances, be a whole death metal album of Winnie the Pooh poems. Elecia is practicing anyway. Transcript…
OpenMV has a new Kickstarter so CEO Kwabena Agyeman chatted with us about more powerful (and smaller!) programmable cameras. See OpenMV ’s site for their existing cameras. See their (already funded!) kickstarter page for the super powerful N6 and the ridiculously small AE3. Note that OpenMV still is committed to open source. See their github if you want to know more. Edge AI is the idea of putting intelligence in the devices (instead of in the cloud). There is an advocacy and education foundation called Edge AI Foundation . This organization was formerly the TinyML Foundation. Edge Impulse and Roboflow are companies that aid in creating and training AI models that can be put on devices.
