Mold casters of /diy/
How durable is Silicones Inc XP-592?
I want to actually use the silicone "mold" for the product- specifically to make wedges for my shoes. Due to a slight leg defect I currently sand dr. scholls down to make a ~3mm wedge. It's very inconsistent and absolutely covers every inch of my shop with blue foam dust.
The end "product" only needs to be crush resistant, but flexible and last. The dr. scholls currently last longer than the shoes generally, because they're not subject to much except pressure as part of the shoe material sandwich.
The idea is I could make a depression negative in the size and shape I need, pour silicones Inc XP-592 and tweak until I get the perfect insert.
At that point I can "mass produce" about 20, s.t. I can have them for all my shoes instead of (as now) stealing them from one pair for another- i.e. my bike shoes vs. dress. In addition to having extras, I feel like the consistency would be better over grinding them down by hand.
So the intended question is, how durable is Silicones Inc XP-592 and would it work in such and application (as a shoe insert)?
Second, would there be a better casting/mold (or other) material to use for the inserts?

Hey /diy/, I have a quick question. I'm helping my dad paint his bedroom, but some paint needs to be stripped. For some reason instead of a paint stripper, he brought back TSP(trisodiumphosphate). He said it can be used to strip paint, but when I google it, it is really oy regaled as a cleaner. Can I use it for stripping? Pic obviously unrelated.

So I'm having an issue with H-bridge and a motor using an Atmega328.
So I wrote a tablet app which sends a bluetooth signal to the Atmega328 via a bluetooth module to control a DC motor with a H-bridge. You press "forward" on the app and it sends one leg to HIGH and the other to LOW on the h-bridge, pressing "reverse" does the opposite. When you're not pressing anything, both are "LOW" and the motor doesn't turn at all. Everything works perfectly on the breadboard version I did.
Now that I've soldered it up to a Stripboard, I'm having an issue. One of the wires connecting from the H-bridge to the DC motor is getting +5v, even when both pins connected to the Arduino are LOW. This is causing the motor to spin forward constantly, and I don't know why or where it's getting 5 volts from. I've checked a million times to make sure the connections are fine, and that solder isn't' touching where it shouldn't. And I'm not getting 5 volts either side of the stripboard "rail" having the issue, so I know it can't be getting it from them.
What's going on?
Black Ink Recipe

Im working on some ink, refillable ink because I'm working on a canvas that has steel parts and ink must be good quality like the result you can get with marsh ink but finding ink like that has been too difficult in my area. I tried a recipe for this in youtube, apparently graffiti taggers do this too but the recipe was a fail or maybe I did it wrong.
I'll write it out so maybe someone can explain what was done incorrectly.
40 ballpoint pens
-Get the alcohol and put 8oz of it in a 16 or 20 oz water bottle
-Remove ink tube from the pens and cut them in half
-Insert the already cut tubes in the water bottle with alcohol
and that suposedly makes ink, I did it like that and the ink looked good....on the bottle, once I used it on my project it looked like water color which was not what I was looking for, my vision is an opaque dark ink. Can anyone tell me what I did wrong? Is there a better recipe? Some of you will post "Buy a sharpie", the sharpie will not give the effect I'm looking for.

recently i built two computers for me and my family, and now i have a huge box full of those air cushions from all the shipments, about 50-100 segments.
Now, i can think of a dozen ways to use them, building a raft, insulating a small shack or a doghouse, light stuffing for a bulky halloween costume, but i dont really want to store a box full of air, just in case i might need it one day.
So my question is, where can i get this stuff apart from ordering fragile electronics? The company producing them (fpintl) obviously just sells the machines to produce them on-site. Can i just go to the post office and ask them for 2 meters of big bubblewrap?
