Chris and Elecia talk about pushing out of their comfort zone, networking advice, adding STARs and action verbs to resumes, using rust, thermo forming plastics, soldering together audio gear, and winning awards. 

If you are looking for an update to your resume or are interviewing for a new job and you haven’t heard of the STAR method (Situation, Task, Action, Result), it is a good way to formulate what you’ve done in a way that helps people see your impact. The Rutgers College Career Development Center has a STAR description that includes how to take your current, boring “did the task” resume bullet point and move it into STAR format and then into resume format to say “got great things done”. There are lots of examples of STAR in practice (ex 1, ex 2). We mainly talked about resumes but it is very useful for having coherent stories during interviews. (Search “STAR resume”, “STAR interview”, “STAR engineering” to find a presentation that works for you. The college career sites are probably the best ones I’ve found.)

On the topic of resumes, if you don’t know about resume action verbs, let us share some lists that will make writing your resume 25% less painful. Again, college career development centers have the best ones (Harvard Business School’s action verb list is good for managers, Penn State has a nice set of verbs for engineering or see University of Houston’s verb list for engineering.)

And on the topic of interviewing and networking, do you have an elevator pitch for yourself? A short introduction of who you are? It is really handy to have that for conferences as well. Princeton has a short write up on putting one together; UPenn has a long write up (ironic given the topic but still useful).

Will Chris be adding the Rust language to his resume? Too early to tell. He’s been learning with Rust for Embedded C Programmers - OpenTitan Documentation

Elecia has been playing with origami molded fabrics, as learned on Instructable Paper Mold Origami Fabrics 3.  The term on Instagram seems to be #plissage and it is covered in (super famous origami guy) Paul Jackson’s encyclopedic Complete Pleats

Chris has built a Colour Duo 2-Channel Colour Channel Strip Kit (a preamp with modifiable analog processing). This kit is from DIY Recording Equipment. He’s enjoying working with it while recording music. 

After Elecia’s New Year’s Resolution to apply for awards, we won a Communicator Award for Individual Episodes-Science & Technology, Distinction 2026 for an episode about engineering the landscape of fear and conservation technology in the wild: 501: Inside the Armpit of a Giraffe. This was quite the honor but after some consideration, we are even more honored to be nominated by listeners for the IEEE Educational Activities Board (EAB) Meritorious Achievement Award in Outreach and Informal Education. This award “recognizes IEEE members who volunteer their time and effort to improve the informal education community, helping to promote engineering to students, parents, and the general public.”

Having fulfilled the objective and gone beyond, Elecia is still planning to apply for the AAAS Kavli Science Journalism Awards where we’ll need to find one or two episodes from July 2025 to July 2026 that show off “scientific accuracy, initiative, originality, clarity of interpretation, and value in fostering a better public understanding of science and its impact.”

Chris and Elecia discuss her origami art show, ponder PRs for solo developers, attempt to explain GDB debugging, and make a to-do list for getting rid of Kanga.

Elecia is having an Origami Octopus Garden art show at the Aptos Public Library for the month of November, 2024. The postcard advertisement is below. There are more pictures on her Instagram (@elecia_white). The python tessellation generator is here.

Memfault’s Interrupt Debugging Firmware with GDB post is a much more considered explanation of GDB and includes pointers to other resources (including using Python with GDB).

Logic gates and origami? Professor Inna Zakharevich joined us to talk about Turing complete origami crease patterns. 

We started talking about Turing completeness which led to a Conway’s Game of Life-like 2D cellular automaton called Rule 110 (Wikipedia) which can be implemented with logic gates (AND, OR, NOT). These logic gates can be implemented as creases in paper (with the direction of the crease indicating 0 or 1). 

The paper describing the proof is called Flat Origami is Turing Complete (arxiv and PDF). Quanta Magazine has a summary article: How to Build an Origami Computer.

Inna’s page at Cornell University also has the crease patterns for the logic gates (pdf).

Inna is an aficionado of the origami work by Satoshi Kamiya who creates complex and lifelike patterns.

Carl Bugeja makes actuators out of PCBs, puts them to work flapping origami bird wings (or moving robot rovers), and takes videos of the whole process. Oh, and get this, self-soldering circuits. 

First, origami: flap actuators video. Your source for the PCB actuators: flexar.io

Carl’s YouTube channel is filled with hardware, software, successes, and misses. Check out his tiny foldable rover and the self-soldering circuit. His projects are open source so you can find the information on github.com/CarlBugeja

Carl has a site (carlbugeja.com) and shows his projects on Instagram instagram.com/carl_bugeja

Elecia worked on a zero-heat-flux, deep tissue temperature measurement system.

Chris and Elecia talk about photons, comets, patterns, other flying objects, and cameras.

Chris uses PixInsight for processing  and has an Ioptron Sky Tracker. Apologies to our southern hemisphere listeners because Polaris is not visible there. There are (of course) other ways to align and even in the northern hemisphere more modern trackers don’t necessarily need Polaris.

Star Exterminator: who cares what it does it has an awesome name. Though it does what it says (on photos, no real stars were harmed in the making of this podcast).

Jupyter Notebooks on a Circuit Python board.

Elecia’s Yoshimura sine pattern generating Python colab. Also, Rigidly foldable origami gadgets and tessellations is an excellent article about Miura-ori and other rigidly foldable patterns. You can see her patterns over on Instagram. (You can see some of Chris’ photos on his Instagram.)

Chris and Elecia chat about origami, learning, whether to future proof tools or buy the cheaper option, simulators, and classes.

Elecia is gearing up to teach another Making Embedded Systems course. Sign up if you want to be in the Yellow Seahorses cohort! Sign up early and often. Sign up other people. Ask other people to sign themselves up and even more other people. Well, you get the idea.

Check out Wokwi! While it looks like it is for Arduino from the front page, there is a lot of work going on to support C/C++ APIs such as the one for Raspberry Pi Pico or the Rust one for the ESP32. Please ask a professor what they’d need to use Wokwi in their class!

In episode 158: Programming Is Too Difficult for Humans, we talked about the Ada language and using it on ARM cores. Learn Ada (at AdaCore).

Chris and Elecia discuss transcripts, listener emails, and brains.

We already have a post about the dangers of using Arduino for professional work.

Elecia got a Cricut Maker to help her make origami and then discovered SVG files were editable (Intro to SVG). She’s putting her origami crease patterns in a github repo eleciawhite/origami), where else would you put it?

About brains, Elecia was reading from Smart But Scattered.
