The recycling here is stupid. There are bins for paper/cardboard, food and miscelaneous, but for plastic, there is only a plastic bag. Most people tie the bag to one of the other bins and untie it every time they wanna dispose of more plastic. This is tedious and lame, in my opinion, so I set out to make some sort of holder for it with some materials I had lying around. Gimme feedback and perhaps some ideas on how to improve it.

Electronics, quick question. Kinda low-fi audio, impedance, frequency response and messing with a resistor in series with a low-fi speaker.
This sucker is my doorbell. The champion engineers at Gira (the manufacturer; German engineers, they said) have decided to let it beep at high volume whenever the doorbell is pressed -- at the outside. My neighbors hate it. When I tried myself it nearly blew my ears out (hyperbole, but you get the idea).
While the talkback volume can be changed, the beep's volume can't be changed (or switched off). Geniuses.
It does have a programming port for its µC, but that's no good, because fuck reverse engineering.
The board is very nicely laid out, and they put a ton of coating on it to get their IP rating, I guess.
I don't really feel like messing with the power amp, however. That'd require a lot of de-coating and probing while this thing is still outside and attached. Messy, with the potential for more mess.
Now, if I put a resistor in series with the speaker, thus increasing the impedance, the total volume should get lowered. My feeling is, this should screw up the frequency response for lower frequencies first, which is not a problem for speech. So I should be able to use some reasonable resistance there, right?
I don't really feel like several trials here, because it's a bitch to install. How does the math work here?
Let's say I want to reduce the loudness by 16dB...

Hey guys, I've using this new (to me) mech mod, it's a nemesis clone, with an atty atomizer. So one coil has been burning red hot and faster than the other, but only when the cotton is on, I removed the cotton and they burn perfectly, and this morning it actually caught fire. I'm still fairly new to the mech mods, so I'd really appreciate some help, thanks!

Sup /diy/? Starting post-secondary, I've come to find many people are riding fixies around campus, more than longboards.
Now I'm more of a mountain biker so I've got fuck all knowledge of road bikes and hipster shit, but I got a pleb gf with barely any skill in anything, and some shitty Walmart bike from 2003, so I figured I could put my talent in building and what not into convincing her to help me convert an old road bike into one. Repainting and all.
It won't be hard at all to get the frame and parts, rich people around my area put their old bikes out for pocket change, I got myself a Fuji for $5 a couple years back but tossed it, but from what I know, there are road bikes with the half in width and the ones with what looks to be an inch and a half.
Will any road bike be compatible for turning it into a fixie? I'd prefer the thicker, city tires and probably only put a front brake on apart from the backpedal braking. What the hell do I put into Craigslist?
