Out of nowhere I got the idea to make an ice cream maker, having no idea where to start, I did some googling, and found that most people either do it by hand, or slap down 100$ for a somewhat large machine
I thought of making a much smaller version, and this thing here is the only reference I was able to find
Anyone here have any experience 3making ice cream, or dealing with machines?
>>758577 the difficulty with smaller machines is getting the ice and salt in together. I've got a small one that doesn't use salt at all as well and I can say that they are pieces of shit, it's just not cold enough without the salt.
if you're doing it just to experiment with ice cream the bag method is probably the best, just be careful to not get salt in your ice cream by accident

I want to attempt to build a computer out of integrated circuits in order to learn more about how they work, the problem is I have no clue where to start and what materials to buy. I realize I need a clock, somewhere to store instructions, and a breadboard to experiment with, but I don't know what else I'll need. Google has nothing for me, there's a few people who seem to have built them and I've seen a few videos of small 8 bit ones, but I wanted to go bigger. Anything you all could tell me to get me started.
>>755210 The most important thing you'll learn from Computer Science (as opposed to Electrical Engineering) is that hardware and software are the same thing. Hardware is just software running on a single-purpose machine.
Turing Equivalence tells us that there is nothing hardware can solve that a Turing Machine (and therefore a general-purpose computer) can't.
This means that before you even think about building a computer in hardware, you should build one in software.

The process usually involves 3d printing, making a negative mold with the 3D printed fugure, filling the negative with wax, get a wax positive and make a heat resistant negative with the wax positive. It's quite annoying.
What I've done so far is I've taken a cheap board that I already had from when I was a kid which was pretty much just a thin sheet of what seems like bamboo with the grid drawn on it and some little knobs underneath it as legs.
I used that as the top since I already had it, and I grabbed an 8ft piece of cheap 1x4 and a sheet of plywood and made a box out of that like in the picture, than I grabbed some pre-made legs that I found and glued it all together.
I didn't do the best job putting... Comment too long. Click here to view the full text.
What are some uniquely good ideas in a certain culture or area for homes, especially pre-industrial revolution ones?
So far I have >Roman/Spanish/Korean subfloor heating >Persian cooling with wells >Tropical wraparound porches for cooling >Russian stove (pic related) >Finnish sauna >Japanese/turkish/Roman baths >Turkic-Mongol yurts Comment too long. Click here to view the full text.
>Roman/Spanish/Korean subfloor heating Only good one listed.
>Persian cooling with wells Wat?
>Tropical wraparound porches for cooling Wat? I've been to Jamaica and it was humid as fuck even in the shade. Best to just use the ac to cool and dehumidify.
>Russian stove (pic related) Smoke in my house? The heat that thing would generate in the summer? The cost of that wood compared to electricity or better yet gas? No thanks.... Comment too long. Click here to view the full text.
Not OP but I studied Architecture and one of my history projects was done on the Persian Arg-e Bam Citadel. The citadel has large towers that catches the wind and channels it down over a pool of water which removes the sand/ dust from the air as well as cooling it before it enters the main parts of the structure. 1500 year old air-conditioning, not bad for sand monkeys.

Find a few guides on google/youtube and go over them. Generally if they appear super easy its because they make shit product or are complete garbage (like that one infographic that pops up here from time to time) Collect a list of... Comment too long. Click here to view the full text.
Their basic starter kit includes almost everything you need. You'll also want to pick up a hydrometer and wine thief. If you stick with their extract kits it's pretty hard to Fuck up. This is how I started about a year ago.
>>747296 >where should I start Search for a homebrew forum online or a homebrew club in your area. Think about what you want to make first, then ask them if a beginner can do it. >what do I need? It depends on what you are making, I assume you want to make beer. For beer you need (beside the ingredients) : a cooking pot , a fermentation vessel with a water lock, a lager tank (same as 2nd fermentation vessel) stirring spoon, measuring cups , few buckets (CLEAN...

I was looking to start with a tub like this, wrapped in insulation foam on the outside, but I really don't know anything about wiring a heating unit for a pool of water, or reappropriating a proper water pump for it. Any pointers?
Hey guys, remember me? I picked up this safe/locker/whatever at a storage auction several months ago, you guys helped me out with it. Although it didn't have keys, you guys directed me to a key code on the back. Anyway, I ordered new keys and got them in and everything, but they almost work. I can turn the lock about 1/4 of the way and it just stops turning.
Any ideas? Again, I don't want to damage the locker or anything, I want to either use it or maybe sell it depending on what it's worth.
DIY means fixing and making things yourself, stepping away from the consumerism and throw shit away when it stops working. What I want to know is some product lines that you only have to buy once, and properly maintained will last forever:

- in fairness, they used to be near-indestructible, think what they sell nowadays is cheap crap running on rest-brand fumes. Either that, or there is one HELL of a lot of Chinese knockoffs doing the rounds.
