Hey, what are some common hardware sizes? I'm not entirely sure where to begin. I am designing a project that will need a few nuts and bolts and non of it is load bearing. Is there a common hardware convention I can find? If I go to home-depot or something there are thousands of sizes.
so, my company will be getting one of these for me in my little office. the 75 watt CO2 version can cut through up to a half inch of wood at a time(that was the estimate given to me by the sales rep). it can cut and engrave, basically everything that isn't metal.
what kind of neat ideas can you think of that I might be able to try off the clock, after hours, and with my own material? I'm thinking of things I'd use with my /tg/ friends like props and stuff, also stuff I'd make for the local fetish community, but I'm very unoriginal

pmma (acrylic) is really nice to work with and its pretty cheap. i have made a few things out of hours with this for robots and stuff and its great fun. spent entirely too long drawing a penis to raster onto a set of coasters
always manual focus. never use epilog auto focus. one time i tried it out and basically 'sensor' switch that tells the table to stop just slipped to the side because of its ridiculous design. the table crashed into the head and the machine panicked. needed to reboot to manually focus to get the table down but on reboot the head would auto calibrate and when it realised it was stuck it would panic again.
machine was out of service for two hours because nobody had a screwdriver to take the front panel off and manually turn the belt in order to drop the table. fucking pain in the asshole. why is it possible for the table to crash into the head in the first place anyway?
>>901119 >always manual focus. noted, for future reference...
>had a screwdriver to take the front panel off and manually turn the belt in order to drop the table. my supervisor is a tool-whore, glad to say that even if it's got a weird-ass screw head on them panel screws he probably has the driver to screw them properly.
>why is it possible for the table to crash into the head in the first place anyway? because in applications like this the engineer is too busy thinking "IT NEEDS TO MOVE A LOT AND MORE MOVEMENT RANGES MEANS WE CAN CHARGE MORE MONEEEEYY; SO I WANT IT TO HAVE ALL OF THE MOVEMENT" without thinking about how adding more "range of motion" will result in equipment crashes.
>spent entirely too long drawing a penis to raster onto a set of coasters no shame man, none at all. I am certainly gonna try and build a folding, layered yolk(fetish type). if I can get that in acrylics I could probably sell them for loads-a-dosh to the local community.
that and I want to see if I can legibly engrave poems onto things, like a little plastic prayer card with the full text of "If-" or "The Hymn of Breaking Strain" on one side cut deeply into the plastic.
>>901140 >weird-ass screw head sad to say it was a pozidrive. there were 3 toolboxes in that room and none of them had anything close. wtf.
i guess it depends on the machine but rastering for engraving can take fucking ages. like a boring amount of time. and then whoever is in charge insists that you have to watch it do its thing for fire safety it gets fucking boring super quick. bring a book. or something to do.
i think it was a 40w, 10mm acrylic took two passes but the thicker... Comment too long. Click here to view the full text.
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
>I'm new to electronics, where do I get started? There are several good books and YouTube channels that are commonly recommended for beginners and those wanting to learn more, many with advanced techniques. The best way to get involved in electronics is just to make stuff. Don't be afraid to get your hands dirty.
