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. Watch the interview: https://app.txplo.re/2974 #AnotherBrightSpark

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
