R: 8 / I: 0IMSI Anyone?
So, I originally had this in /tech/ but decided to move it because, well, that was a rather stupid place to have it.
I was thinking if anyone was interested in RF/Radio enough to want to build an IMSI catcher? Or rather work on on the specs for an "open source" one, mainly for fun.
One could just take a hackRF or bladeRF hook it up to an amp and a nice antenna and have some awesome software poke at the GMS stack, but that is old hat. So my main proposal is to attempt to build up everything into a self contained unit. Integrated RF amp and everything. Something like a 4U rack case or a Pelican 1670, nice a portable, just attach power and antenna and go.
The feasibility of this is fairly certain, it just depends on who wants to join in and help. I think it could be a cool project that involves a wide array of skills from /diy/, any thoughts? -
R: 2 / I: 3heatsink mods & cooling
hi /diy/, I was wondering if anyone has tips on modifying stuff like routers and single-board computers with heatsinks and/or fans. I've had a couple routers basically burn out on me because they basically had no way to disperse heat, and as far as I can tell there's no such thing as a consumer wifi router that has fans or real heatsinks.
also if anyone knows a way to add passive cooling to a smartphone that doesn't make it significantly larger I will love you forever. -

R: 21 / I: 0Ghetto Wine-Making
So I'm in the dorms at a US college and since I'm pretty nerdy and socially awkward like most of us, there's really no opportunities to get alcohol until I'm 21. So I decided to take the DIY approach.
As somebody who has never brewed anything in his life before and just had the internet, I decided to get two S bend airlocks (with included bungs), some 5g packets of Red Star champagne yeast, and some big containers of juice.
I poured out a bit of the juice from the bottle, and a gram of yeast was measured out and poured into the juice. The bung was inserted into the mouth of the bottle and the S-bend (with some water inside of it) was fitted into the hole.
A day or so later it started bubbling, and after 9 days of brewing, the grape juice turned into (pretty shitty) wine and the apple juice into mediocre cider.
My test subjects rated (based on taste) the grape juice as an average of 2/10, and the cider as a 7/10.
Since I'm doing this sort of brewing completely blind, and obviously don't have the sorts of resources to do anything more complicated than this, I just wanted to share this little project and maybe pick some of your minds for some more advice. Let me know what you think!

R: 4 / I: 0NAS configuration
I intend on building a small NAS for the purpose of file storage and backups. I have two questions, the first regarding the computer being used for the server. I was looking at getting the HP G1610T ProLiant Micro Server and also another 8GB of ram to go with it. Is this a good choice or should I go the whitebox route or with some other pre-built computer?
My second question is in regards the storage. I'm thinking using ZFS, and having 3 1TB hard drives set up in RAIDZ (so 2TB of usable storage). I was then going to have another 3 TB HDD installed to maintain a backup of the zpool (probably using rsync). Is this a good way to go about doing this or is there anything crucial I'm missing? -

Office lainons, this ones for you.
stop eating at lardbutters every afternoon. quit feeding your paycheck to vending machines. Oscar Meyer is not your friend. You need to be making home made ramen and it needs to start with mason jars. wide mouth, 16 ounce mason jars packed with anything you want. noodles, soykafake, miso, peanut butter, and a bit of hot sauce with some spinach do well. now go to the break room and fill it up with hot water. Pack an apple or a bag of granola and thats lunch.
the best part? you can make it ahead of time and a 12 pack of mason jars is dirt cheap. Need breakfast? pre-cook 9 grain cereal or some oats and pack one of these full with a bit of peanut butter or coconut flakes. once at work, hot water should do the trick.
put 10 of these together, 5 breakfast and 5 lunch.
If anyones interested I have recipes for soymilk, peanut butter, kimchi, and tofu (from scratch.) -

I have a power glove I'm pretty close to getting to connect with my computer as a peripheral so retro-future-izing is a sort of hobby of mine. Should I gut the bot and completely replace it all to make it run off completely new technology? Should I outfit it with omnibot replacement parts and have it perform as it's supposed to? Should I turn it into a mobile computer tower? I really just don't know. The thing is over 2 feet tall and 1 foot long and wide so it's pretty damn hefty.

R: 26 / I: 6file server + electricity manager
I'll buy a raspberry pi and make a file server + electricity manager with it.
Three SATA and three IDE drives would be hooked to it, to be accessed through SSH over a LAN.
The Pi's GPIO pins would use relays [1] to control a home-made switchboard where I'd plug my other energy-consuming devices (laptop, amp, etc) to provide current to the ones I'm using at a given time and switch the rest off the grid.
My issues:
I haven't used a raspPi or GPIO before so I'm not sure they can do what I want them to.
I think relays are the way to go, but I'm not certain.
This layout would require three IDE to USB carries, and they are a bit expensive and hard to find.
Letting the thing have one wall plug instead of two would be good.
I still haven't thougt about other parts like casing, a display, maybe sound isolation for the HDDs, etc.
