What's the best (free) 2d cad/blueprint software?
I need to design a model car for a project
19 replies and 1 image omitted. Click here to view.
you can do 2D is Sketchup if you want
also it's better to make a 3D model if you want to design something
you can then turn it into 2D planes
>also it's better to make a 3D model
Depends on the design itself, sometimes 2d is better.
Fusion 360 is my personal favorite, but 123D Design is dead simple if you've never used CAD software before. Honestly, cars are hard to model, if you're not already competent with 3D CAD software and 3D modeling, you're going to have a rough time.

Or it's fork-ish librecad (that is missing command line, or at least I cannot find it in there).
>that is missing command line

it is there, but it sucks, it is about 10 characters long and I think you can only type the command and not coordinates.

so li 10,1 20,1 becomes
click on command line, type li, hit enter, go to mouse draw line, click back on command line, type new command.

they changed alot of the commands as well, pretty much just killed the workflow that makes qcad great and cluttered the screen up with a pile of buttons.

But it is FOSS and community developed so it must be better right?

Hi, i'm relarively new to this section, so i'll thank in advance for your attention.

I have this old fashion radio, which turns on by the right dial (the "Volume") and has an analog dial that scans the signals. Now, i would very much like to connect, in some way, this radio to an online radio (for example electroswing-radio.com or some other swing radio). Any ideas?

Probably not what you have in mind, but you could just plug an FM transmitter into a computer and tune into that station on the radio, and play whatever you want from the computer.
OP here, indeed I need to apologize, my request was far from easy to understand, given the way I stated it.
Trying to reformulate it:
I have that radio, which is an actual radio, and would like to be able to listen to online radios once i turn it on, so, keeping the outer looking of the radio i was looking for something like an arduino setup to shove inside it and to listen to a site, not an AM/FM radio station. I definitively should've spent more time explaining in detail my request, my bad.

That is exactly what I was looking for, thank you very much sir.
>should've spent more time explaining in detail
Or just spend less time not checking on a thread you made 11 hours ago. You're welcome, also google it yourself next time, internet radio is the kind of hipster shit tarduino's lap up so don't pretend you didn't think someone would have made even one neat tutorial.
>Or just spend less time not checking on a thread you made 11 hours ago
Last thing I checked before going to sleep and first thing I checked in the morning. It's because, you know, maybe I live on the other side of the world so to constantly check it while sleeping would've been kinda hard.

> You're welcome, also google it yourself next time
Did it, but found nothing satisfactory, so I thought that maybe here I would've found some new or better ways

> ...internet radio is the kind of hipster shit tarduino's lap up...

Why throwing shit man? Are you stressed? I literally said i'm sorry for the poor explaination and asked for help.

Use a RPi3 (it has comfy WiFi built in) and put high quality potentiometer behind thr station dail. Wire it as a frequency devider that goes into some ADC chip because the RPi cant read analog signals.
Program something that the data that is coming out of the ADC is selecting online stations in some way.
Problem: it takes propably seconds after you turn the dail until it connects and plays a new station. Solution: listen to neighbor stations on the dail simultateously on mute and turning thr dail should basicall just unmute them.
Bonus: ad scratchy noises and talkover between the stations
You should be able to hack into the input line of the built in amp with the outcoming signal of the rpi

Self amalgamating tape.
>It's starting to feel manageable, works out to a 875 deg/s max

Why exactly do you want to be able to spin like a top if you are just learning to fly that shit in a perfectly straight line?

There is no practical, real-world reason to have rates that high. I haven't crunched the numbers or anything, but if you watch people pilot really fast quads, you'll notice that their actual adjustments are very sedate. You should already be starting to yaw for the next gate while you are hitting the closest one, then you roll to correct your vector as gently as you can get away with.
I want to be able to get used to having a expo rate. The center of my stick is pretty forgiving, and the area around that starts to get into the expo curve

Pretty much just trying to practice with rates that are similar in shape to what I'll eventually run

What are you eventually doing that you expect to be literally rotating entirely more than twice per second on any axis? That gives you a few hundreds of a second to stabilize onto the vector you want, which is edging across the line of what human reaction times can reliably achieve. This means that you are going to be constantly running into the classic over-correction feedback loop which leads directly to loss of control and crash.

If you racing, the most extreme maneuver you will ever have to perform is probably in the ballpark of an inverted 180 degree hairpin performed within the span of half a second to a full second. Anything past 360 degree/sec rates is overkill for any realistic quadcopter related activity. It's different for fixed wing because you aren't changing your thrust vector when you roll a fixed wing aircraft.

Low rates are good for racing (I know people that fly ~300°/s at races) but freestyle requires much higher rates (800-1200°/s is normal). The expo curve means you can make small, smooth movements using the majority of the stick travel, then just the ends of the stick travel gives you the full rotation speed for doing flips/rolls.

I fly 800°/s on all three axes. If you look at the stick overlay on picrelated webm, you'll see that to do the first half of that roll quickly, then complete it slower, I use the full 800°/s for a moment.

Okay realistically what can i /diy/ these into?

Pinterest is a scam
Does anyone actually like Jack Daniels or is it just successful because of its branding?

It's a shit whiskey that tastes like exhaust fumes from a diesel engine.
Pinterest is just super fucking weird man, stay away from it. I reckon there's some weird black magic shit going on with it. The wife seems to love it though so make of that what you will

Pretty sure a lot of it comes down to being an iconic brand people recognize. That and the "le epic manly whisky ex-dee!" meme
agreed, I don't like liquor in general, my thing is wine
It's just a very iconic logo, like Coca-Cola which is poison nonetheless
>Pretty sure a lot of it comes down to being an iconic brand people recognize

this exactly, I'm custom flogging t-shirts in my own language for show-off artsy-philo-whatever pseud students.
I pick an author or school of taught or concept or whatever and decline it using easily recognizable logos. I'm not inventing anything, but this kind of stuff often only exists in english, if at all with the super niche stuff.

It's all via word-of-mouth for the moment, but shit sells like crack in Skid Row, you'll probably see me asking about setting up a simple order and pay website in a few weeks, if things keep going this way

Hello all, was wondering what the cheapest way to teach heat tape to turn itself off and on when needed would be.
Situation: There is no heat ducting going to the bathroom at the back of this little rental property out in bfe, need the water pipes to stop freezing.
> Previous plumber was definition of "handyman special".
> Am looking to avoid extreme increase to electric bill.
Unheated bathroom is on back of haus. Pipes pop into the unheated "Michigan" basement, then pop out...into the yard.
I am thinking of hooking the temperature sensor from one of my old smoker/grill DIY projects from last year, the kind that can have alarms set to it, then using the signal running to the speaker as the trigger for the automatic switch.
Maybe trigger a timer as well, so it shuts itself off after a...while.
Any slicker way to do this?
Temperature sensitive switch
Thermostat plug
There's tons of shit exactly for this.
If you want it timed as well you can bumble around with a tarduino or something.
It's called self regulating heat tape.
Fucking hell anon, the pic you posted is literally a heat cable with a termo switch. They usually switch on at +3 and off at +10 and their purpose is -exactly- what you're describing.

i can't think of a worse IT job that didn't involve a printer

(during a round of layoffs at that shitshow, an especially salty bastard stole all the copy protection dongles, knocking out the drawing database, most of the cnc machines, and the weighbridge)
I just took a course at my university that taught the basics of machining. About half the class was dedicated to learning G-codes but if i had a half-decent professor that kept me motivated I would know a large deal about it. Teaching yourself part time on your own should only take a month or two.

I used this website called CNCcookbook that has a lot of good reference materials if you have any questions. I also have a nice powerpoint that you could look over to teach you some of the basics. Just reply back an i could email it to you.

In the real world though... you dont really need to know how to do it manually. All machine shops just use various softwares. I learned it all on MasterCAM. Its not to difficult to learn on that but im not sure if theres any better softwares out there anyhow.

Good luck in your efforts.

Pick something else.

How much would it cost to build something like this? Assuming labor is free and you have basic tools.

Man if I had access to large amounts of beef fat you bet I wouldn't be using it to make soap.
My ex made bodywash for an elderly relative who went through litres of it by buying cheap as fuck soap that smelled ok, shaving it into boiling water and adding essential oils to add smell. Worked fine, made like 5 litres for $2-3 worth of soap.

Don't remember recipe/ratios but pretty sure she just boiled it.

yep. and i dont want to move because my family lives down the street from me and i dont want to struggle finding another place as i have only been on my own for a year.
Record it, build a case, take it to the slumlord. If they do not solve the issue, take it to tenancy tribunal. Get those faggots evicted. You are in the right and you will win the day if you go through proper channels.
Start calling in noise complains to the police.

Depends on the state/country. Never heard of a ' tenancy tribunal' and I've lived in 7 states and 4 countries. If he is in the states and the landlord isn't willing to play ball then his recourse will be to void the lease and move out. He is not anymore entitled to rent that apartment than his neighbors.
