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... Comment too long. Click here to view the full text.
>>941628 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.
>>941750 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... Comment too long. Click here to view the full text.
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?
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!
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.
Trying to build a complete enough set of OK tools for as cheap as possible now that I have moved... Comment too long. Click here to view the full text.

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.
Craftsman isn't the best, but the warranty kicks ass, and if you're not turning wrenches for a living, they'll... Comment too long. Click here to view the full text.
>>941474 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.
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 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
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?
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.
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.
>>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.
>>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... Comment too long.
