Can’t decide which blows my mind more:
• the Apple ][‘s peak sales year was six years after its introduction
• the Apple ][ was an active SKU for 16 years
• the Apple ][‘s lifetime sales of 6 million units is routinely bested by a few *days* of iPhone sales

My PR for WiringX has been merged! In my last blog post, I mentioned forking the WiringX library and adding functionality.
Today, they've been merged. We've also talked with the folks at Milk-V to merge their changes into upstream WiringX.

My blog is still alive! I've just been super busy this year :)
Last week, a friend of mine gave me a RISC-V board with the goal of running I2C code. The board was quite an interesting experience, so I wrote about it to share it with you!

New blog post time!
This month, we take a look at a topic I’ve mentioned before. That is, hardware reverse engineering. We take an Arduino Uno R3 as an example board, while I guide you on the basics of hardware reverse engineering!
