Hey you Canadians browsing here, how interested are you in buying cheaper 3D printer filament in country?
Me and my buddy are looking at starting up a business, and we'll be selling the ABS filament at $25 per kg, and it's going to be tax free, we'll be paying it for you.
The tolerances of said filament will be 0.5% for the diameter, and 0.07% for the roundness.

I've been playing around in my head with how I might be able to live away from home with the least amount of money, aside from lodging with friendly people. With a sleep schedule where I only sleep for 20 minutes every few hours, it occurred to me as a possibility to travel without buying a room, which would save a lot of expenses, and perhaps prepare me for more extreme circumstances if they happened.
I'm not thinking of anything foreign or wild, just trips to urban areas such as Las Vegas or New York that seem like they would be conducive to that kind of living.
So my naive mental outline includes sleeping and recharging battery power in a place like a public library during the day, and once they close, I can imagine being able to pull off some rest while riding public transportation once late at night and once early in the morning.
Food seems easy enough to handle, I've lived on cold food before. The main issue I see is hygiene, although maybe I might be able to find something at a public pool or a gym. I can easily pass as a college student as well.
No harm in throwing the idea out there. Any recommendations on ways to sneak some personal time out of general city areas, any useful stuff to throw together in the bag would be interesting to look at.
making your own screens' support

has any of you already done some screens' support ?
the plate screwed behind the screen seems not that difficult to create, 4+1 holes and a press to give the central volume.
With tubes of steel, I can also attach them easily. making then a central tube, going into the Desk, or, direct in the wall ?
What are your experience or thoughts ?
Simple circuitry question

Greetings my fellow /diy/orks,
I have a pretty simple question about an extremely simple circuit, but i'm almost entirely ignorant when it comes to electronics, and google isn't helping me much.
I make lamps that are powered with LED strip lights. For most of them, I just cannibalize a 12v charger of some kind and solder the wires directly to the solder points of the strips. (pardon my lack of proper terms)
However, for others I solder on a 9v battery adapter to make a portable light.
In both cases the lights are just wired in series, and I know for a fact that they can be powered from either end of the strip.
So here's my dilemma: A customer wants me to make him a lamp with both options. He wants it to have a cord, but also be able to take a battery for when he wants to move it around. How exactly should I go about doing this? As it is I can only think of 3 different scenarios.
A. just solder both the power supply wires and the battery adapter wires to the same points, on top of each other.
B. solder one supply onto each end of the strip, powering it from one side or the other as needed.
C. have 2 entirely separate circuits with different lights for each circuit. (i don't want to do this, as more overhead costs and less space to work with, but if need be I can)
what are your thoughts on this? I know that having 2 power supplies can be tricky and that batteries can explode if they short circuit, so i dont want to just learn as i go.
