So, I'm fresh out of motivation for videogames and most other stuff, so anyone on here want to give me a quick how-to for basic forging? Like swords, blades and the such (or just generally metal shaping) etc. thanks in advance
So I had this idea to make refrigerator/heater to make kefir in a consistent way. I'll use a peltier element sandwiched between two stock AMD heatsink/fans and I built a board to provide power and switch hot and cold sides to the peltier element with two DPDT relays (one should be enough, the second one is just to prevent a short from happening).
What I didn't think of was a better way to limit current to the peltier than using a big ass resistor in series with it. I have a 5a 12v PSU and I expect the control circuit to use 200ma at most and would like the peltier... Comment too long. Click here to view the full text.
The cheapest incubator I can find is of a shitty DIY design and will cost more than one year of electricity, the proper ones are expensive lab equipment.
A peltier element will maintain a temperature difference between the two sides, since I don't want more than 30º of difference it's better than a "buying a mini-fridge". If I wanted to buy one rather than making one I'd post in /g/, not /diy/.
I'm guessing this is more of a /g/ thing, but what are you asking? Do you want to run/boot off of an external USB drive? it's possible, just not as fast. If you want to replace your internal 2.5 inch HDD with the 2.5 inch HDD inside the USB enclosure, that will probably work and also be faster.
Ok so i have a dc motor, pic is my motor. Im trying to make it variable speed. I bought a bridge rectifier and it works great at full speed. Now i tried using a rotary dimmer with a capacitor with little sucess at low speeds and torque. So im going to get a pwm but not sure how to wire it. Do i still need the bridge rectifier? Or does pwm act as one.
I was wondering if there was a way to trick my roommates into thinking they have control of the thermostat?
My girlfriend has rheumatoid arthritis and it hurts her joints when she gets cold. Our roommates know this and even after many discussions, they have decided to keep putting the thermostat at 65 and "cool" instead of 70 and auto like we originally agreed on, because they're hot and they said she was lying about her joints. I'm tired of the arguing and bickering and everything becoming a pissing match. We have 6 more months on our lease so... Comment too long. Click here to view the full text.
That's a tough one. Roommates? Are you Jack Tripper? If not, and you pay the bills, which I would not be surprised by based on your responses, either step up to the girlfriend or the roomies and use a thermostat with a pin #.
>>900772 reliability, yes harbor freight ones are cheap, yes you can buy several for the cost of a real bit... no, buying new ones and saving the money will not unfuck that 300$ figured hardwood board that just got ruined when your cheap harbor freight bit failed...
if your using it to fuck around with, or for regular around the house projects, then harbor freight is probably fine... professionally however you'd be better off with a better quality bit.
>>900798 Rust less. Bought a cheapo set of bits from HF causes I needed one right then. Put them in my bit storage toolbox and came back to them a year later, all were spotted with rust. All my other drill bits? Spotless. Even had a desiccant pack in the toolbox and those cheap pieces of shit STILL rusted.
guys, i'm going full survivalist for some time in my parents farm i need to make a shelter that will keep me of the ground and protected for about 3-4 weeks can you guys give me instructions/suggestions? here is the terrain info >stational forest (like a savanna) >it is stating to rain >i will have basic resources for construction like some wood and clay > i'm only taking some rope,machete ,hand axe and a lighter
not entirely sure where to start, has to be a partial, setting up the bass and getting a good outline for the proportions shouldn't be too difficult, but what i'm more concerned about is how to get the detail. more specifically for the transept to the left.
out of basswood, or what would be more appropriate?
tl;dr how do i go about details for a basswood architectural model?
I need a knot that can carry out this function below. Can anyone point me in the direction of the type of knot it's called and a guide to do it?
>one end of the rope attached to something to be pulled >middle of rope fixed/coiled to something solid >second end of the rope loose, and can be pulled on to cause the first end to contract, without having to tie the second end in a knot or anything to stop the pulled object returning back to its position (i.e pulling the second end...

>>900661 not without some kind of ratchet device in the middle. like a sprung pawl that is at an angle and sprung so when you pull it one way it moves but pull it the other way and the pawl clamps the rope. but just a knot? no i don't think so.
unless you count a taut-line hitch, a truckers hitch, a munter hitch or a guarde knot.
i dream of some day being able to run a business selling a product to either consumers or manufacturers. i do not yet have a product in mind, however i have recently abandoned a bachelor in health and nutrition in favor of chemistry (chemical engineer), it is my hopes that this education will give me the tools and inspire me to design a product in the likes of chemical compounds for medicinal, construction materials, or even the food industry.
Even though i do not have a product yet, i still feel like figuring out what it takes to start a business,... Comment too long. Click here to view the full text.
>>900645 First of all congratulations for not being another wageslave just like all other so called STEM geniuses. You really need to do market research, dont bother trying to manufacture anything that is already being done startup costs are too high. If you aim for new stuff startup costs will be lower simply because you have no competitiors. For example my first (failed) business was 3d printed statues. If Kodak were doing it Id have gotten nowhere but they werent so i had a foothold. Now ive moved on to delivery drones... Comment too long. Click here to view the full text.
