Currently live in a shitty apartment with my mom. I recently got hired and am gonna make enough money to move out. However, I don't want my mom living in the same shit apartment. Problem is, anything with higher rent is going to be an issue for her. So I have two options. A. Find her a better place and help pay the rent B. Renovate the shit out of our current apartment. I like option B more considering she likes the neighborhood a lot, and I wouldn't have to help out with the rent as much. My only concern is that the building is old, and maintained by a super...

My girlfriend has a cat who likes to scratch wooden door frames. Getting rid of the cat is sort of not an option.
What's the thick material that sticks onto surfaces and can be removed later? It's like heavy wallpaper. A lot of people who get cabinets with old shitty interiors will layer the insides of the drawers with it, etc. I'm thinking of just covering all the doorframes with it, then removing it before we move and sanding off what few scratches are left on the wood. But I can't remember what it's CALLED.
I need to build a microbiological incubator, but I am finding some troubles that I ask you guys for help.
I live in a fairly hot place, so I need a heating AND a cooling system on this incubator, and so far, my best idea was peltier modules for both, being controlled separately by two thermostats (as I am not very versated in electronic and programming, I couldn't think of a way of one controlling both).
How would you guys do it? The colling and heating part as well as the temperature controller. I need some sugestions.
Incandescent light bulbs are... Comment too long. Click here to view the full text.
>>987575 hi mushroom bro. yes a 50w peltier will give you a good couple of degree range for incubating agar plates. you will need air exchange though. what sort of max temperatures do you get inside your house?
>>987575 Ideally what you do is site your chamber in a room that is already environmentally controlled so that there is very little fluctuation. Air conditioning will typically aim for a set temperature and heat or cool as necessary. If you set the room a little colder than you need it will give you headroom to add heat which is much easier than removing heat.
Insulation is important, it acts as a low pass filter for heat, if you have enough insulation your chamber will sit at the average temperature of outside.

I never worked with them, to be honest. In fact, I plan to make a kind of a big incubator, so I can frutificate mushrooms inside too, besides the agar plates (just a idea so far). Here it can easily reach 36°C on a hot summers day. Maybe 3 to 4 peltiers would do the work.
Ideally, I agree with you. But I don't have any kind of environmentally controlled room, sadly. The insulation part I think I got covered, but we'll see in the future.... Comment too long. Click here to view the full text.
What the cheapest conceivable way to become a homeowner in the Pacific Northwest? I'm assuming it would be buy land in the middle of nowhere and build your own minimum viable house, correct? How cheap can you go?
On one hand You are Right. On the other one I don' have that much pieces to try with. Having a manual would Tell me which pieces to buy on the Internet. Most of my pieces are from castle/pirate sets. Not that good to work with 40k :|
>>985964 the do it yourself part is using that thing inside your skull to concoct an original mix of ingredients that one would not normally be able to order at a bar without specifying what independent ingredients to put in it, if you want your drink to taste better then grow the peaches/sugarcane/etc/etc
Okay, so I have a rescue guitar from the 80's that actually sounds really good with fuzz or high gain, and the novelty of the instrument is that it has a speaker built in. After replacing all the sub-par components, including the speaker, I find that the only thing left to address was the fact that the 9volt battery inside is drained super quickly.
I have some soldering experience when it comes to electronics, but I am not an expert by any means. I was hoping that someone here might have an idea for some way to negate the use of a 9volt, either with an alternative... Comment too long. Click here to view the full text.
>>985468 You might not need all 9V to begin with; make sure there's not a vintage linear voltage regulator inline as well.
step up would require only a buck-boost converter, depending on the power draw this might be a single chip solution or you might have to make one. They are not as complex or hard to put together as you might think.
If you really want the nigger-rigged less expensive setup, use 6x AAs (or AAAs). 9V batteries are just 6x AAAAs in a hard case anyway (if you don't believe me, take one apart with pliers)
So, I want to prank a friend, and I would like to know how to glue a pvc dildo to the hood of a car.
Would hot glue work, or would I have to do some dildo to a wood spacer to the car kind of thing? Obviously I don't want to sand and prime the surface, and I'd prefer the bond to be able to be broken without damage. If this isn't possible, I'll find some other way to be a dick to him. Probably by leaving a box full of dildos in his trunk or something.
Alright, I have this idea I want to build. I have a Raspberry Pi 2 (Pic related). For my project to work, I'd need it to do two things. 1. Measure electricity 2. Remotely control a servo. Could it do it? and if so, how do I do it? inb4; Stick a magnet on it
If you want to measure a voltage you need an ADC, and possibly a voltage divider. If you need to measure current you also need a shunt resistor. To control a servo you should use a servo HAT. Look up all the tutorials for the stuff I mentioned and you should be able to make it work.
Yes, it's more work than clicking a few things on each other.
