I have a mad-scientist project in the works. I'm going to be spending 24 hours at a tent/farm party outside ottawa next weekend, and I'm wondering if it will work. My math says it will, but others are saying it wont.
Now then, here's my project:
a 45-Watt peltier-based fridge connected directly to a car battery rated for 500CCA
How long will the fridge run?
I have it calculated that it could supply for little over 100 hours, but I cant confirm. I just need to be sure it will last 24 hours, and thats all. The battery will not be needed to start an engine after.

I'm thinking about opening my small business selling imported goods basically Online (E-commerce), although I'll rent a small physical place to obey my country laws, and store some of my goods.
I have a small hatch car which I plan to use to make delivery when they're geographically close to me and also more profitable than hiring a 3th part company like FedEX.
Since I'm starting from the Web to real world, I need to get a professional site to look trustable.
I already have a domain (.com.br)
People usually avoid buying from small sites without references, they usually google the company looking for other people opinions who had made any kind of purchase from said company.

Would Urban Homesteading be appropriate for this board? Last year I started gardening pretty heavily as a way to stay healthy/save money and I really enjoy it. I hate my job and have $15,000 saved up, so I was considering quitting, moving to some failed city, buying some abandoned/seized property and gardening full time.
I guess, as a place to start, what are some good places for an urban homestead? Detroit seems like an obvious, but I imagine the property taxes would fuck me pretty hard.
All other discussion is welcome as well, though.

/diy/, I could use a hand. I'm working on an electronics project and am needing to replicate a numerical display, blue backlit with black digits. See supplied pic. Now I can handle setting up the hardware and software with the PIC I'm using, I just can't find a suitable LCD display.
It needs to be about 2" tall, 1" wide, blue display with black pixels. Does anyone know of any good sources for LCD displays?

So here's the thing DIY\
I found this website that has free online engineering courses, something i'd like to be when i'm older. However my only problem is, its online.
My work routine involves me working a lot and then waiting in an area that has no internet, bandwidth and I swear, no phone signal. Is there any way I can make a digital copy or webrip clone of the website so I can do the courses offline, on my laptop?
Smoke for a Hero

So I'm planning to cosplay this motherflocker and I want this to be as cool as physically possible. Among the accessories I'm looking into are a sorta of fan-pack I'd wear under the cape to keep it blowing at all times, but that seems easy enough. What I'm having trouble with is smoke bombs.
See, I want smoke bombs small enough to holster in a utility belt, but that function with no heat. Dry ice looks like my only option, since titanium chloride smokes are kinda sorta horribly poisonous, but I'm not sure how to get much smoke from a dry ice bomb. Keep in mind, I don't necessarily need an explosion. Anything pocket-sized and safe that'll create enough smoke to be a spectacle is good.
So here I am, /sci/ /g/ and /diy/. Any ideas?

Hopefully this is within the boards rules. First time visitor so let me know if this isn't the correct place. Does anyone have experience with on demand water heaters?
Pictured is our opalia c 13 e water from Saunier Duval After returning to our cottage, it isn't functioning. The pilot light is on and will spark but main burner will not light.
All valves are clean and no blockages, injectors are clean and no blockage, inlet pressure is fine, cleaned the lint arrester, voltage is a-ok on PCB and gas valve.
Turned to Google for about two hours but mainly French websites are returned and very little resolution on other forums.
Got a full arsenal of tools and a few spare parts on hand.
