I love the expandability of the Bus Pirate. Fully open source with a great community, it's easy to add new functionality to interface to different hardware and busses.
It took 3 revisions to get right, but the DDR5 RAM SPD adapter is now available. Use with the Bus Pirate to read and write DDR5 SPD EEPROMs. HSA pin is grounded so blocks can be unlocked (offline mode). UDIMM (desktop) and SODIMM (laptop) supported.

Ugh. Looking for one particular component. I cleaned and sorted my stock of parts 18 months ago, and it looks like it's time to do it again 🤷♂️

Let's sum up the first 2 innings in Milwaukee.
Brewers:
20 hitters came to bat
14 of them reached base
9 runs
3 hits by Jackson Chourio in 2 innings
Cubs:
2 guys in their lineup haven't even gotten an AB yet!
It's the most Brewers game ever

At the gym raw-dogging the rowing machine (no phone, no music, no earbuds; just rowing along with my thoughts), when a jagoff behind me starts loudly talking into his phone. His phone that's on speaker.
Not even pretending to be using that elliptical; just leaning on it, hollering into his phone.

How much hardware does one need to read the code out of an MCU if the "proper" programmer isn't available?
Well, so far I've got a @buspirate.bsky.social, a Saleae, an Arduino, some perfboard, & way too many cables 🤣
(Not shown: soldering iron and tools, scope/meter, various hand tools, coffee)
