This is a long shot, but does anyone here work for or have experience with a packaging supplier?
I am in the middle of creating a frozen food product and I am trying to figure out a sleek packaging design that will allow the contents to be easily removed without the chance of the product sticking to the inside.
I can obviously go with a poly bag like a Popsicle is contained in, but that is not modern and sleek enough. It is essentially a cylindrical piece of ice measuring 6" long and 2" in diameter. I have been in contact with silicone and glass bottling...

Tetra pack or milk in a bag

uhh, holding the package in ones hand for a minute should be sufficient to slightly melt a layer between any packaging and your frozen food. some people prefer to run under water from a tap rather than get a cold hand.
you dont need any special coating.

Right now I am using 250ml and 500ml graduated cylinders as molds and to remove the product I run them through a hot water bath. They don't come as easily as you think. I bought a piece of 304 steel pipe I'm going through the try and use as a mold to see if that works better.
On the consumer end I don't want the costumer to have to run it under hot water.
I bought this ghetto-ass car amplifier for like 5$ that was broken because one of the resistors was jammed so tight between the speaker terminals that it cracked and shorted out. it has a ton of op amps on it (TL084CN) and a TL494.
Im pretty new at EE, for reference i just figured out the difference between a bipolar and unipolar power supply. What can i build to get the most xp?

Build a little inverting amplifier from op-amps. It's fairly easy once you get over the learning curve of looking up the datasheet to get pinouts, knowing what to connect where, making the connections *to match your design* (protip: you'll fuck this part up more than once).
Once you have it built then try rewiring it to make it non-inverting, then differential. They're easy modifications.
Once you have a basic grounding (pun intended) from doing this then try building a power supply - this is a rite of passage for most electronics hobbyists and there...

I have two teapots (one porcelain and the other cast iron) that I can't use. The porcelain one has some brown buildup of some sort on the inside of the spout and the cast iron one seems to have some other brown stuff coming off of the inside top when I wipe it off inside to dry it off. Any advice on cleaning them or what to do?
Clean them.
There might be some rust in your water.
Try cleaning the inside of the porcelain one with limeaway or something similar. Alternatively, stop being a faggot and just use a pot.
Muriatic acid.
How could I turn this into a helmet. Just curious if i could. Also, if not which animal skull would be the best helmet?

I did a cool jigsaw puzzle and moved it onto my side table and WOAH it's the same exact size as the table! How would I go about making this the table top? Plexiglass? What else? Any glue? Glue the plexiglass? Glue to table? Where to get plexiglass in the right size? So many questions!
thx
Victoria's secret, eh? Nasty boy
Plexiglass or even normal glass. Looks like there is a gap along the side, you can attach with clear silicone just to seal it. Or drill holes and use a fastener of your choice.

I bought a used 1/2 Armstrong (standard, black oxide) ratchet for 5$.
Turns out the reason it was at goodwill was because they sheared the pawls off trying to unbolt something (probably with a cheater bar).
A rebuild costs ~30$
A new old stock one on ebay is ~60$
You can get any number of quality ratchets for slightly more than the rebuild kit.
At what point should I throw it away vs repairing it? It is made in the USA and feels like a quality ratchet.

Dude, just save up around $300, then wait until father's day. Sears will have a pretty damn complete socket and wrench set on sale (ship for free to the store), and then stop nickling and diming yourself to death.

Oh, and their sale usually includes SAE and Metric, a driver set, and allen key set. You need to add in pliers, full screwdriver set, and then whatever other random shit you'll eventually need.

The 309 piece was $200, my bad, and I got free shipping to my address.

I would like to make my own gps tracker, Im used to using pic related, but the distance it can reach is max 2km in the forrest, and i need more distance, I thaugt about i could make something like tracking a phone? over gps? anyone got any ideas?
>>941468
>but the distance it can reach is max 2km in the forrest
? what does this mean? i have a old garmin and it doesn't have any limits
>>941468
after 2km or so i loose signal to the dog, i must go in the car and search the dog, if i come around 2km near him i get his signal again.
it is the same with the gps from my friends
also i use the older model too
Can I multi use it to clean my stove coils or will the copper get damaged?

Dude, just use a bucket, a capful of oven cleaner, and a night's rest.

No, the entire setup.
Hi /diy/
I recently bought a DC inverter for a battery box I put together, and I want to use it to power my projector; However, when I have it plugged in, the power input on the projector makes a nasty buzzing sound, so I've cut the juice to it so I don't damage it.
I'm thinking it's under amperage. Is there any way to get such a setup working?
>>941334
First off you're using the wrong kind of battery. You need a deep cycle rv battery. Draining a regular car battery will ruin it.
Next you need to figure out how much power your projector uses and how much power your inverter produces.
Define buzzing sound?
Depending on the type of inverter this may be normal.
Could you check what sort of output signal the Inverter is supposed to give out? If it's Modified Sine Wave, then you can expect the buzzing sound.
>>941342
This.
Most inverters put out a modified sine wave, which is ok for some things, and not so great for others.
You would think though that the projector would have a power supply circuit that converts the ac back to DC and has some filtering on it. My best guess is that the projector has a step down transformer that is chattering because of the not so smooth sine wave out of the inverter, in which case it shouldn't be too harmful.
My work wants to put a coffee pot in a high traffic unattended waiting room. We would have a donation lock box cabled to the table and charge 50 cents a cup.
What are considerations? Should the 50 cup coffee urn be cabled down? Is a bicycle cable enough for the lock box? Are there other safety and security issues?
Any comments appreciated.
what's that cost, like $75? and it has to be moved at least a couple times a day. no, you should not lock it to anything.
>>941251
If you're this concerned, screw it to the table.
I've been thinking about starting brewing my own beer at home. Any advice on what to get and how to start?
If you want a simpler method you could get the make your own beer kits that sports stores sell. I think bed bath and beyond might have them too
>>941277
I don't think there is a bed bath & beyond in Turkey. I found a starting kit online but I wasn't sure it would be enough.
>>941245
I'd suggest trying wine or cider before beer as it's generally simpler for getting an understanding of how to make alcohol whilst not needing any specialized equipment.
Buy some distillers yeast off ebay and look up a guide on youtube for apple cider.
You ferment it right in the bottle the juice comes in, can't be simpler.
Hey guys,
I am a Zbrush sculptor and I was wondering how I would be able to make toys and or figurines from 3d to real life?
I see all these 3D printed models but quality wise they are terrible.
Some of the Hot Toys artist work in Zbrush. Since most of you are clever folks here, I was wondering if you guys knew how to do this?
From 3D to a full coloured figurine.
>>941212
If you don't want to build/carve/model it by hand, you'll have to look past consumer grade 3D printers and be willing to spend a whole lot of money, or find a service that offers high quality printing for a fee.
Otherwise, just buy some polymer clay and practice sculpting.
>>941212
Enjoy getting sued.

Creating a 3D model on your computer and then turning that into a physical object is illegal now?

I want to design and build a mechanical clock.
I have access to a 3D printer, so most parts can be manufactured that way.
I'm looking for resources (free books, if possible) to calculate. My other choice is just look for videos and blogs and make the calculations my self.
I have some experience with gear design.

>Clock making general?
So, is that your question?
>>941184
What do you need to calculate?
Pendulum frequency depends on length and force from escapement also I guess.
To go from 1 second to 1 minute you need a gear ratio of 60:1 to go from minutes to hours you need a gear ratio of 60:1
There are probably a billion different escapements you can pick but I doubt you would find a book about it.
If you want to make the gears from scratch the only resource I know is woodgears.ca, guy is mentioned in diy regularly and he has some weird wooden shit.
If you want metal...
