@HybridGlucose 甚至不用 Arduino,做好轉接線直接插手機也行

Great respect to all technical writers. To learn everything about a topic, you can just open a document, read it, and it can actually be (eventually) understood? Magic. /me rewrites the second paragraph of my blog post again and it still doesn't look right... ​:woozy_baa:​

#TIL Isolated Photovoltaic MOSFET gate drivers exist. Unlike normal isolators, these chips don't need any secondary power supplies and obtain their power solely from LED at primary with solar cells at secondary. Only a few microamps are available to charge the gate. But they can greatly simplify the isolation circuit when speed doesn't matter. It's how Solid-State Relays work. One chip has turn-on time about 50 μs into 200 pF, not bad. #electronics

It's just unfortunate that NEET is also the name of India's (politically much criticized) national exam, #NEET tag is full of those posts... The #BanNEET and #neetmustbebanned tags are especially funny without context.

@HybridGlucose 我記得是有合格的型錄就可以吧,有點忘了

@HybridGlucose 確實是個好問題,你要查什麼機器的形式認證資料?
