Hi /diy/! I'm building a RC/autonomous tank and I'm looking for a good platform to work on. I found the (pretty popular) Tamiya platform https://www.pololu.com/product/106 but it's a bit small for my purpose. Can you recommend me a bigger platform (15-20cm wide) that is not prohibitively expensive? I do have access to a 3D printer, but I would prefer an off-the-shelf solution.
>>912379 Just to be sure, you are referring to http://www.vexrobotics.com/276-2168.html Yes, they are on the pricey side, but I think this will work. My only problem is that the tread is not rubberized, and we need good grip on smooth surfaces. Does anybody have experience with 3D printed tracks?
Heat it and cut it with a chisel. Use a band saw, dremel, drill holes in the area you want cut and then grind it clean, temper it to make it softer for cutting, cut it with a torch, score it and try and snap it in a vice, bend it back and forth until it fatigues and breaks, cut it with an explosive shaped charge, slice it with thermite, mind bullets, corrode a line across it with salsa and a DC power source
Alright guys, hopefully I don't catch a ton of shit for this.
Basically I am doing a Gofundme to afford the machinery and equipment necessary to make prosthetic limbs. The plan is to use the CNC mill and 3D printer to make other things I can sell to fund the creation of the custom prosthetics, so that I can give them away for free, or at least at a very low cost.
The problem being that I have had no luck getting any donations, despite trying to build up a social media following.
So I guess my question is where are some good places, or people I can talk... Comment too long. Click here to view the full text.
>>912257 Forgot to add, in terms of purity it goes:
PIC -> STM -> Arduino -> RasPi
In terms of ease of use it goes:
RasPi -> Arduino -> STM -> PIC
I'm a PIC man myself but in fairness I think that's because I got started before the arduino and raspi... Comment too long. Click here to view the full text.
Hi guys. I'm wondering how to make a display where 3 or 4 leds slowly fade in and out. I'd like a blue, white green and red one and I'll have them behind some acrylic to wash the light a bit. What I'm wondering is, if its not possible to do this with single components. What about a arduino type thing ? I don't really want to learn or buy an arduino. So I was wondering is there some little chip one can programme and put on a breadboard that could achieve this task ?? Many thanks..
Arduino is complete overkill for a project like this so you're right to look for something else. Any low end microcontroller like something from the PIC12F or an Atiny families more than enough. You can implement PWM LED fading in software on any digital output, it doesn't have to be an "analog" (PWM) output.
> inb4 somebody tries to start a PIC, AVR, ARM debate.
One of the reason the Arduino is popular is because it can be programmed just by plugging the USB cable into your computer. Most dev boards come with bootloaders... Comment too long. Click here to view the full text.
There's nothing really wrong with Arduino, while it's certainly overkill for the application, it's still a good learning tool as long as you realize that Arduino should just be a stepping stone towards pure AVR or other platforms. Nothing wrong with either of them. The thing you quickly need to realize is that 'Arduino' is really just the ATMega mounted on top of a vastly overpriced board, if you go the Arduino route, first up buy a Chinese one, such as Funduino, it's much, much cheaper than straight Arduino and works just as well.

So, I got really curious with Nikola Tesla's ideas of making the world a better place by building towers that could use "cosmic" energy and somehow transmit it to people for free. Then came Thomas Moray years later looking into Tesla's work and made his own device that worked and was verified by eye witness engineers and Congressman. My question is where would I start to experiment/Diy at home to expire these things for myself. Any schematics and details would be much appreciated for an Electrical engineer hopeful.
>>912127 From what I've read Tesla was basically tinkering along the likes of solar power. It's just that it all sounds weird and mystique when you read about it in the words and terminology of his time. So buy a solar panel and there you have a free radiant energy to experiment with at home.
I want to start brewing beer to continue my alcoholism without also becoming bankrupt. I have been looking around for the necessary equipment but I don't want to buy one of those lame marked up kits and other sources seem kinda vague like "just get a bucket and a hose" without being specific. So do any of you have experience brewing beer and what set up can a get away with just by going to Home Depot?
Hey guys, I've googled around, called a couple of auto shops and no one seems to have a straight answer on this. My alternator is pretty much done for on my 2005 cobalt. 2.2 liter engine. Now, every guide I've checked doesn't deal with 2005, it seems to all be 2008 and up, and the lay out of the engine bay is different. Every guide and how to fluctuates on whether or not you need to remove the passenger wheel to get to the alternator. I do not have the equipment to actually lift the car safely while I'm working on it, and I'm wondering if anyone else... Comment too long. Click here to view the full text.
Backstory: car died on my way to work, I work overnights so I won't work on it until the morning. I just want a solid idea of what to expect before I go digging around. If I do have to take the wheel off, I may just take it to a garage with the part and let them do it.
I'm in my 3rd year of Kinesiology studying to be a physiotherapist. And I like what I do, but It's honestly just become mundane to me. It's not bad but its not exciting. I like the idea of helping people. But I'm not exactly proud of the job, you know? Like its not really hard work, you just stand in a nice office all day.
I recently started getting into diy stuff as a hobby and doing some small jobs with my carpenter friend and some metal working shit with my engineer friend and holy fuck its all... Comment too long. Click here to view the full text.
>>911849 Depends mostly on you and your personality, I guess. I got my multidisciplinary bachelor's doing all kinds of different stuff I kinda liked but had no strong feelings about. I dicked around for a while after that and I was pretty satisfied, but it still felt pretty hollow all in all. Signed up for trade school on a whim and it's the best decision I've ever made in my life by far. The more I do it the more I like it. It's the first time that I ever felt like I truly found my way.

Yeah, I'm just having a hard time because I already took time off after school. I feel like I wasted a lot of my life growing up playing video games and fucking around. Never gathered any hobbies or skills. I'll be 30 by the time I get my masters for physio. Not much time to be switching careers at that point. This is again why my friends advise me against it. Trades and tools and all this stuff is brand fucking new to me. I never did any of it growing up.

>>911849 >>911849 This is one of those scenarios where money really doesn't buy happiness.
I've worked in construction on site for 8 years and every day is different. There is however a ceiling to what you can make unless you're willing to take on the responsibility of labour working under you.
I've had offers to go into work in offices at a desk relating to construction and I've tried it but I simply wasn't happy.

Hey guys, I've got an indoor gardening project that would optimally have a fan blow on it for 30 seconds every hour. Problem is, my fan only continuously blows. Is there something like a light dimmer I can use that would limit it's electricity to what I need it to be?
