How do you know that everyone (especially people who live in apartments) has a 'wood pile' just laying there ready to be used? Guess what--they don't. They probably don't have any of that stuff you are mentioning that you take for granted or have gotten free--and the fact of the matter is, it drives up the cost. Sure, WB logging is optional, but for the sole purpose of describing & replicating what you have done, it and everything else has a cost to the otherwise clueless newb, for if not for them, who else would you be posting this for?
I too doubt a "clueless noob" will take on this project but I believe your assumption that THEY were my target audience is entirely incorrect. In all likelihood, they are probably too busy daydreaming about a twin turbo setup or a 5.4 swap.
IMO, the ideal candidate for getting value out of this DIY would be someone who has some academic/hobbyist experience with electronics yet was clueless about exactly how the engine sensors interact with the ECU to control this car. If you may recall, I was trying to figure out the electrical characteristics of some of these sensors since i figured the ECU tuning forum would have the most knowledgable folks in this area but you chased me out. Basically, IMO, the target audience for this DIY is someone like me 2 months ago.
I appreciate you attempting to be honest about the pricing but it still baffles me that you are hung up on the little crap. You just have to think creatively.
1) Any box can be used: A kleenex box, An old toaster, An old phone, A VCR rewinder, hell, even the stock glove box. Surely someone with a car and an interest in datalogging would be able to lay their hands on one of these items for $0. It just requires you to "think outside the box." >badum-ching<
2) We aren't talking about high current wire (like your battery relocation cables) and we aren't talking about very long lengths so there are a ton of sources of small wiring that would be more than sufficient for this project. Examples: VCRs, old power supplies, etc. Even in the middle of nowhere, again, I maintain that anyone can find wiring for this project for little to no money. If they really had no money acquire a suitable donor item, I doubt they would take on a datalogger project.
3) Scrap wood. Noone, not even a noob, is stupid enough to buy a 4'x8' plywood sheet for this project. You don't even need the wood -- you can just screw the screw terminal block into the box if you want.
4) Oh, I forgot screws. You got me there. Add a few cents for those. Maybe a few bucks if you go nuts and buy the 100pc pkg.
I live in a very urban area - SF. My tbird barely fits in my one car garage (in order to close the garage door my front bumper overhangs the bottommost step of the stairs to go up to the main level of the house) and my working area isn't much larger. If I can scrounge these items with a little creativity and little if any money, most resourceful folks will be able to do the same.
