Resin Casting

Resin Casting 3 posts and 0 image replies omitted. Click to view.
So I have 1.2L of Polyester Water-Clear Resin, and I need more than I have. About 2-3x more. Shops are closed tomorrow (bank holiday) and deadline is Tuesday morning. I do however have a whole lot of glue-gun glue. Can I heat this up and mix with the resin? Will it hinder the casting? Also it doesn't need to be 100% clear (some cloudy swirls would actually look alright) but ideally it'd look like one homogenous block rather than with seams all over. I was thinking of heating up a bowl and mixing all the glue in it together then pouring in at the same time as the resin. Sound feasible? If not I can just use the gun and build up the glue but then it'd be in ugly little lines throughout the model. I'm casting a fairly thin, flat plane - about 165mmx20mmx900mm - so that should be about 2.97L of material needed right? Please halp DIY. Pic related, it's the resin I have.

Anyone here know how to clean this stuff off this here coin, and how do I prevent it from happening to others in my collection?

Raspberry Pi thread

Raspberry Pi thread 7 posts and 0 image replies omitted. Click to view.
How would I hook up a RPi to my garage door wall switch? I plan on setting it up to be open-able via local wifi. Hooking it up to the actual opener is impractical for me, because of how high it is in the garage. I popped open the casing of the wall switch and I could see the circuit board with the wires connected to it by the way. I really want to set this up for my family; my mom's almost always pissed about not being able to get inside through the garage.

Hey /diy/ I got an old ps2 with heaps of games but I can't play a lot of them because they are from the wrong region. My question is: is there any way to softmod my ps2 so that it'll play them from all regions? Any help is much appreciated.

Hey /diy/, any computer techs... 17 posts and 0 image replies omitted. Click to view.
Hey /diy/, any computer techs out there? Desperately need help! Having problems with my desktop after installing new hard drive - had to remove GPU and heatsink/CPU to install hard drive. Put everything back together and no video display whatsoever. Managed to fry a pin on CPU, so replaced CPU (slight upgrade). No dice. Replaced motherboard (same model). Still no dice. Have triple checked all connections, power supply seems to be working, RAM in good order. Hoping it's not my GPU, it won't seem to register video through motherboard either. Any takers? Any help would be hugely appreciated. No tits to give, on girlfriends laptop...

I need some help with my turbo lamp! I found the inspiration for this on google/pintrest (there's a lot out there), and decided to do it myself. I've got pretty much everything covered...except how to attach the turbo to the support beam, and how to properly attach the lighting fixture. I can't weld it, because the turbo is aluminum and colored, so I don't want to risk damaging it. Anyone got any ideas? I'm really drawing a blank. Pic related, my lamp so far.

I've seen you guys know something about arduinos, I was wondering if you could help me to program this little fuckers. I've followed all the instructions, downloaded the 1.0 and 1.3 versions to try out with, reinstalled drivers, tried with different attiny folders and nothing it keeps giving me the same error, the error it's linked to a reset on the board. I've tried the capacitor method and a resistor at 119 Ohms, pressing the reset button... but nothing. Checked connections of my protoboard programming aid and I reproduced the same circuit on a breadboard. No matter what I do I get the same error. I guess it's the arduino board fault for being fake and maybe having different setting to reset it. Anyway I'll post this here and I'll be glad to try any of the things you propose to solve this.


Terrarium 5 posts and 0 image replies omitted. Click to view.
I'm looking to make a large glass terrarium capable of keeping about 90% humidity for my pet lizard. Any success stories/tips for making large glass terrariums? Is this cost efficient compared to simply purchasing a large vivarium? Where might be the best location to obtain these supplies?

Finishing 3d printed parts

13 posts and 0 image replies omitted. Click to view.
I have about 30 3d printed parts for a university project, they are printed in ABS. I plan on finishing them in plasti dip, but making them smooth first is the real issue. If any of you have any experience with finishing 3d printed parts please give your advice. My plan is to sand them lightly, then either dip them in acetone or use acetone vapor to make them smooth. Next I would fill any big defects with bog and use filler primer, then finally sand them and spray on the plasti dip.

Hey guys, need a bit of advice. I've been making more stuff with PVC recently and I love how versatile it is. I've made a crossbow, model guns, mountable handles, and of course a dozen potato guns. I want to make something like in the picture. That's a fiberglass rocket cone, and I'm looking more to make some model tank bullets. They're around 30mm in diameter, so I'll be using 1" PVC (I know it's quite a bit smaller). My first idea is to slice one end of the pipe into triangular quadrants and use a heat gun and a glove/mold to force it into shape. Anyone have better/more seamless ideas for making PVC "bullets" and cones?

can I use a breadboard for analog circuits at, say, 5Mhz? Or would it cause problems. I will make a filter on it. Would I have to actually use solder and stuff?

Audio Mixer Build

Audio Mixer Build 9 posts and 0 image replies omitted. Click to view.
ok this is my first time asking for /diy/'s help, so bare with me please. My ultimate goal is to build and audio mixer and microphones for my drum kit. I could live without building microphones if they are difficult, but I don't see why they would be. I will start with my reasoning: Mixers are really expensive, and I am hoping that building one could be much cheaper, although I may be wrong. It just seems like a fun summer project. Ok, so here is what I would like out of this project. >Multi track mixer (as many inputs as i can afford) >preamps for mics on each channel >EQ for each channel >volume for each channel >pan for each channel >Probably the XLR/TRS combo inputs >multiple headphone outputs for monitoring >RCA output Microphones >don't have to be great quality, just have to be reasonable for drums All in all, I'm not extremely worried about being able to make studio quality stuff... just want each drum mic'd etc. and I want to be able to record (I would just use the line-in on my laptop) Any ideas on how much it would cost? and where I can look to learn how to do this stuff? I have already downloaded a few texbooks. I have a little background in the physics (I just finished physics II--electricity and magnetism), so I think I should be able to at least learn how to do this. I'll try to answer any questions

Hi /diy/. I'm a chemistry student, but I'm interested in how raw minerals and shit is turned into usable chemicals. Every once in a while while browsing wikipedia there'll be a short snippet about the original process for making such and such chemical. I figure there's a few people here who like to know how to do X or how to make Y from scratch in case of apocalypse, or armageddon, or what have you; but what about chemistry? I'm having a hard time finding a modern text on the production of chemicals from raw materials that's doable on a scale that doesn't require a gigantic plant. Mostly all I can find are archaic alchemy-age papers and journals about individual processes. Does a modern guide to alchemical-level chemistry exist?
