I strongly encourage investigating Industrial Design courses if you want to get into stuff like product design. Ideally a certificate in it could open some doors, but again if you show a flair for it in your personal projects that might be enough.

Can you reasonably come up with a new idea on how to make something more efficient/streamlined? Most "inventors" just have a eureka moment. If you are good at connecting the dots this should come naturally.

I have this playhouse in the backyard. Previous owners built it. There's a slide on it, and that's the only reason the kids go near it. The other 99.999% of the time all it does is attract ungodly amounts of wasps and bird crap. What advice would you have for how I can dismantle this playhouse piece by piece and what tools will I need?

I made my first electronics project when I was a little kid, with a few nails, some wire, a board, and a piece of steel strapping, a home made capacitor out of tinfoil and wax paper I got from my mom. To flash a light bulb. LEDs were not invented yet.
I remember my dad giving me a relay about a year after that. I’m like “holy crap… someone already thought of this and did a way better job”

Of course, I did not amount to very much despite such early promise.

>>2795211
Exactly.

You didn’t mention what the project was, practical advice cannot be offered. Are you going to hit us up for project ideas? I just gave you one.

I’d agree with you a lot of the time, but this circuit uses series pass JFETs, and I refuse to believe someone can do that without at least some clue.

CD4007s are the best way to get 4-terminal MOSFETs, they’re great.

>>2795199
To design custom circuits for a given category, you need both an understanding of theory, and experience building and troubleshooting existing circuits. Just one or the other won’t be enough. Get your hands dirty with some simple projects, the OP has a few in its GitHub repo. I made an elektrosluch for my first project, it was fun.

I would start looking on pinterest or google images, take note of the rooms that you think look nice. Then try and find affordable ways to make your space look similar. If you like having minimal stuff, that's cool but I think when you start filling out your home a little more it will feel more inviting. Just start will small stuff and figure it out as you go.

Nah, I grew up with big dogs. (Went through three of them.) Our yard was nice, and our house was nice. Things weren't broken or damaged. You bought a house from dumbshits who let their dogs run wild.

Do you need your parts to be particularly strong? If so I'd recommend a printer that can do ABS out of the box. Also 400 euros seems kinda steep for a KE, that's more Ender V3 price (not the KE).

>>2795340
>organic shapes
Learning blender might not be a terrible idea. It isn't parametric (for the most part), but it's good for more organic shapes, and IIRC it has a plugin that makes it passable for mechanical CAD work. Though most people I've seen use it also learn a proper parametric CAD program, and import the sculpted shape into that once it's refined. If you're not a Freetard like me, go for the free version of Fusion360 or Onshape, that or pirate Solidworks.
>3d scanning and AI
It's getting there, but the landscape is awash with tech demos and expensive scanning hardware, it's not really consumer ready yet. Though maybe there's a youtuber keeping his finger on the pulse of the 3D scanning field that's done the dirty work for you and can tell you the latest cost effective setup. I still think we're a while off being able to scan something in and have it be good enough without any hand finishing though.

Casting is absolutely the way to go, there's lots of custom rubber or composite things that you can't buy, and being the guy who can 3D print a mould and cast one will set you apart. Both things like silicone and urethane, but also forged carbon. Though stocking all the different resins is expensive if you want any sort of variety (e.g. a range of shore hardnesses).
A router isn't as useful unless you can do aluminium, but custom wooden parts might be a good market if you know where to look.
A diode laser can do business cards and engraved art, but I don't think its potential is that great by itself. I use one for PCB making.

Thank you for the reply, so would Bambu Lab X1 Carbon priced at 1900euros be worth it? And yes, I would like to print some parts for car aswell for tabletop cnc machine and other household items

>>2795374
X1C is maybe overkill, you can get a P1S and add a hardened nozzle. Without the botnet, a K1C or SV08+enclosure is probably good enough if you don't mind tinkering a bit. Watch some reviews to see what's worth getting and what isn't, spending 2k on a printer deserves a few hours of research at the least. I recommend Aurora Tech's reviews.

>>2795380

>silicon mogul and oust Taiwan
You really need to read up on the value chain here, it is huge and long but money os not where you think it is.
It starts by mining quartz sand, most is from Norway. That sand is sold in huge bags, and is shipped to Switzerland or Japan, where they melt, refine and grow monocrystalline boules, which then are zone refined and turned into wafers. Each wafer is 200 mm in diameter - and sells for a few dollars.
Value comes when these are shipped to places like Taiwan and these are patterned and turned into chips.
Then the wafers are sliced and packaged (often Indonesia) and shipped to customers.

Lower grade silicon is melted for use with amorphous photovoltaic cells, but that doesn't make you rich either.

Cram in a fuckin wood screw, it's greasy but gets her done. Otherwise it looks like 10mm M3x1.0 dome head machine screw with additional BS, might want to add locking and plain washers. Or threadlocker. Unthreaded pin at the end could be to make it look more like a dick or maybe for alignment/locating of components but purchased by the engineers since they were cheaper but with extra crap..err....features...not really needed. Likely what anon said already, easier for assembly liners.

> prices out a SEER 21 9k minisplit
$800 is a little low.for a quality unit. I was referring to the cost of power, or how much energy even the most efficient model will draw in a poorly insulated camper/trailer.

You thought I was referring to the price of the unit. No.

>>2792969
I think he should get a mini-freezer, make popsicles, and stick one up his ass. A lot of blood flows through that sphincter.

Like above anon says, running aircon or a heater will suck away all your power, requiring a system 3x the original size - for Aircon - and so much bigger than that again, for electric heat, that in the case of regular full-electric heat, you'll never fit it in a mobile application. Maybe a small electric heating pad.

One of the issues as I pointed out, is trailers etc are poorly insulated. It's more of a problem with heat than aircon, hypothetically, because basically what you are usually doing with aircon is dehumidifying, first. And trailers can be more airtight than they can have a good R value. But because your trailer or van etc must be parked in the sun for it's rooftop panels to work, typically the cabin is absorbing more heat, than if you simply parked in the shade and used a fan.

Small scale swamp coolers only work well in low humidity. That, therefore is highly dependent on where you are using and building your system. The amount of water needed, can cause issues, too.

>get an inverter generator that can do 1500W and get some sort of A/C unit that can vent out the heat.
>Heat, just use a propane/diesel heater
Would be more efficient, but I was partially hoping to set up a climate controlled storage space that I could just leave alone for a few days at a time. I'd be a bit too nervious leaving a gas generator or a propane heater running unsupervised for a few days. Maybe I'll look into beefier systems

>>2793037
>you'll never fit it in a mobile application.
>trailers etc are poorly insulated
clearly stated it was for a shed. the RV pic was just something i grabbed off the amazon listing. I was even considering splurging a bit on 2x6 framing, so i could fit more insulation

>>2793232
If it's a shed, for the price of anything you'd want to do solar, just getting an electrical line out there would be infinitely cheaper. You get a window unit and bam, climate and humidity controlled and you just don't have to worry about it.
Heating and cooling are extremely power-intensive. There's no way around it.
To generate enough solar reliably, you'd need an easy 4kw of panels. This by itself could run you $2k if you got them at bargain bin prices and 50x25ft of space.
Then you need battery capacity like mad. We'll assume it runs hat half-power during the less-cool, less-hot parts of the day (though this is underselling things).
You'd need nearly 10kwh to 12kwh of battery storage to adequately. in case of shady days where you aren't getting 4kw from your panels.
This is another 5-8k cost.
And this isn't counting the inverter and solar charge controller. Throw in another thousand or two for one that won't burn your shed down or be inefficient, because cheap ones will suck away hundreds of watts just by being on.
So for way over $10k.... You can get an electrician to just run you some lectric for you climate control.

However if you can do without climate control, cost goes down dramatically. If you just want some lights and to charge your power tools and booster, a single 200W panel into something like an ecoflow delta 2 would be plenty. $150 for a panel, plugged into a refurbished delta 2 that goes for $600 after taxes. EZPZ.

>>2787879
Got a semi-chink made box with a 12.8V 100Ah LFPO battery and a 1000W sinewave inverter.
Apparently the inverter wastes up to 15 watts when running.
The fans engage when the inverter outputs more than 50-60 watts.
So I bought 12V lights and other accessories to save on the inverter usage (and fans noise).

I also experimented at home, running stuff, taking note of usual and peak power.
Noticed that the claimed "1000W nominal, 1600W peak for 2 seconds" is bullshit.
It seems to sustain 800-900W (enough for a microwave), barely keeps up with 1200-1300W peak for half a second.

No solar panel, yet at least 80% of the claimed 1280 watt/hours are there, so I can camp at least three days without charging.
It sports a couple USB ports; phone charging will be slow but hey, it saves me an extra powerbank.
Clearly I won't park the car in full sun.

I wouldn't go for homemade shit. I'm not fond of aborting a mission because some component was way too chink.

>>2794740
Hard to follow who is who, in a thread, but if that's your only contribution, here is my criticism&advice (you posted publicly so that's what happens):

You always derate chinese ratings by 25%. If it says 2000w on an inverter, you never load more than 1500. Unless it has a very strong track record, supported by other reasons (GroWatt, and the newer EG4s, only for examples, there are some others). Signature Solar / EG4 (technically different corporations) 6000w units (and I think the 18k) are OEM'd by Luxpower. Whereas an earlier 6k (I think the 6500 something) had a bad history of lemon-itis.

A lot of chinese producers, have no conscious, at all - will cut all kinds of corners. To the point of you scratching your head, why would they in such a self-destructive way? There is word of mouth, and you are going to tell everyone on these boards that it's a lemon. Censorship? I know every company has a CCP rep, maybe like the funny handshake club - you can't say anything bad about member's companies.

Usually if someone is doing a 12v system, the minimum advised inverter is 2000w, pure sine wave, like an WZRELB. 2000w because the assumption on a U.S. 120v outlet is it can handle 1500. Once you add in surges from motors (like power tools) it's easily up in the 2000+ watt range. 12v systems max out around 3kw.

The correct answer is to install solar panels and also bypass your meter, so you can explain to the power company why your usage is so low
