This isn't the only way to do it.
It's probably not the best way to do it.
But it's how I did it.

Great video again, thank you. Just two notes: 1. There is an explanation for the "spacer issue" in the product description: "We include a set of short and long Nylon spacers (M3) that can easily be modified (cut) to fit. Unfortunately, the design flaws of Arduino UNO and MEGA boards make it impossible to use “stock” spacers in all four corners" 2. The ULN2802 is a 4-channel Darlington driver from Lanker Semi. The datasheet you pulled is the ULN2802A from STMicroelectronics. Basically the same thing but with 8 channels and for 20x the price.

I alternate too between brass and sponge. 9:30 Getting behind on the beer!

So Lead was certainly deprecated if not banned in soldering some time ago right? But recently I got back into retro Atari ST and that leaded solder is sure easier to (de)solder. Is leaded solder still available or you have a large stockpile? Any special usage notes?
-
Is your cool sub counter still in sync with YouTube? It's been the same number for a decent amount of videos.

We make similar content, you in English and I in Spanish hahahahaha 😁 Greetings.

The I2C pins (SDA and SCL) are different on the Uno and Mega. How does the shield manage to work with either ?

Hmm, interesting.
