The review covers setup, configuration, and real-world use of the ThinkNode M1, plus a full video walkthrough. Dive in for practical tips and let me know what you think!

Just published a hands-on review of the ThinkNode M1 Meshtastic node!

The CrowPi 3 is an all-in-one STEM kit featuring 30+ modules, a touchscreen, and support for Raspberry Pi 5, Arduino Nano, micro:bit, and Raspberry Pi Pico. It simplifies learning electronics and coding. Explore my full review: https://app.txplo.re/crowpi3

Just tested the CrowPi 3—Elecrow’s new Raspberry Pi 5-based STEM kit. It integrates 30+ modules, a touchscreen, and supports microcontrollers like Arduino Nano, micro:bit, and Raspberry Pi Pico. Read my full review and watch the video: https://app.txplo.re/crowpi3

Waste heat capture turned out to be more impactful than solar integration alone—it's where the additional efficiency gains happened.

I've completed my review of the Canaan Avalon Q Bitcoin Miner with hybrid solar and heat recovery integration—covering the practical realities of sustainable cryptocurrency mining. The heat recovery results were particularly interesting. https://app.txplo.re/avalonq

This article is a preview from my upcoming course on filters. I use real experiments and simple explanations to make the concepts accessible, whether you’re just starting out or looking to refresh your skills.

New blog post: I explore the impulse response of first-order filters, with a full lecture video included. See how low-pass and high-pass filters react to sharp signals, and learn how to analyze their behavior in your own circuits.

I’m designing a hands-on course on RC and RL filters — Python, CircuitLab, real circuits, and the Analog Discovery 3.

What would you like to see in it? A specific circuit? More audio examples?

💬 Let me know below or on the blog.

Fun fact: I nearly quit on electronics education early on. It took one tiny Arduino project to reignite everything. The full story’s in the interview.

I was interviewed by Neale Mighall on the Another Bright Spark podcast.

We talked about my path from engineering to education, how Tech Explorations came to be, and why I believe structured curiosity is key to learning anything.
