Lost to the sands of time, unfortunately. The first such blog that started me on the mode of research was for a fancy RF photo-flash trigger by the name of Radiopopper. I don't believe that blog is still up with its original content, but you might be able to find it in the Wayback Machine by way of the Strobist photography blog. It didn't differ too much from the updates that you would see today on any given electronics-based project on Kickstarter or other crowdfunding platform. Dave's developed a few products and vblogged a bit about the process, most recently the µSupply, which should give you some idea of the concerns of a product designer.
The "blocks" I'm talking about are just a vague, non-enumerable abstraction covering many levels of structure, akin to sentence or phrase structures. Transistors are akin to "The dog barked", short and simple but with plenty of room for subtlety, and SDRAMs are akin to "A man, a plan, a canoe, pasta, heros, rajahs, a coloratura, maps, snipe, percale, macaroni, a gag, a banana bag, a tan, a tag, a banana bag again (or a camel), a crepe, pins, Spam, a rut, a Rolo, cash, a jar, sore hats, a peon, a canal--Panama!", quite symmetrical yet twisted to get in and out of. There are no exhaustive lists, but you can occasionally find the odd category list on Wikipedia such as
https://en.wikipedia.org/wiki/Category:Single-stage_transistor_amplifiers with somewhat comparable variations on a theme.
In any case, you have to start with the rudiments. The maker movement and some of their leading distributors (Sparkfun, Adafruit) have come out with their own elementary electronics instruction resources and walk-throughs, sometimes centered around the Arduino physical computing platform. If that's not serious enough for you, Forrest M. Mims III has published a ton of renowned instructional texts and mini-notebooks, including
Getting Started in Electronics.
The Art of Electronics is more straightforward and might intimidate some beginners not accustomed to close reading, but I don't think you'll be too intimidated by it, especially when you can use the web as an auxiliary resource. If radio interests you, the ARRL's got a lot of material online and in print for beginners on up to amateur RF engineers that might pique your interest, and getting your Amateur Extra ticket is a decent test of your knowledge of the basics of RF and of electronics in general. It all depends on where you want to go.
