OK, I want to build my own desk, but I'm not great with carpentry. I currently have a drafting table and a large computer desk which takes up too much room, so I want to combine the two into a single desk.

I want a "drafting table" portion so I can work on my art stuff there, as well as a standard portion which I could put my scanner, tablets, hard drives, etc. on. So I was thinking an L-shaped desk with a drafting table on one side of it. Does /diy/ have any tips/guides on doing this? Also, I'll share my apartment garden pics, as that has been my main project this year.

I also started a hydroponic garden with green peppers. I sprouted the peppers in an Aerogarden, but when they started getting larger, I moved them to five gallon buckets. I'll post a few pictures of those. Anyone who's thinking about getting into hydroponics, don't be intimidated by it, it's super easy stuff and produces quite a bit of stuff quickly. I knew nothing about hydroponics before starting this.

It probably some nasty high speed parallel interface at an obscure voltage, bet it has a really simple controller so you'll need to refresh it at something like 60Hz. Backlight looks like a CCFL so good luck generating the voltages for that. If you really want to use an LCD like that in a project I'd recommend you get something with a well documented controller and/or interface.

I'll have no problem with the tube backlight. I'll be using it in a delaminated form with natural light as the backlight.

I'm fine having to manually feed in a clock signal to refresh. I'm wanting to keep this project as cheap as possible (and as light as possible where i can), so I'd really like to use this display.
A quick google of the numbers in your pic reveals nothing. If you know the model of the camera it might be worth searching for replacement LCD for it, that should give you the part numbers so you can find a datasheet.

What are you planning on driving it with?

I'm considering selling home made bread.

It's easy as fuck to make, but people act like you performed a miracle whenever you bake it. Ingredients are cheap as shit, the average loaf of bread costs forty cents to make. But then people who can't bake will turn around and spend $3-$5 for a loaf. Because it's "artisanal".

I'm interested in building LED Grow Lights (or potentially other grow lights).
I don't plan on necessarily growing marijuana, but rather focusing on tomatoes, melons, and various crops in more of a Ron Swanson-esque self-sufficiency and getting off the grid sort of way.

My vague idea is a pattern of Red, Orange, and Blue lights in parallel, in front of a reflective fixture, hooked up to a power supply, and possibly using an old computer fan to keep from overheating. Part selection is what I need the most assistance on.

why the different colored bulbs?
>why the different colored bulbs?

So, they wouldn't be bulbs, in this configuration, but LEDs, which emit different frequencies of light.
The reason why is because plants contain two different types of light-absorbing pigments, chlorophylls and carotenoids, which are specifically for absorbing different wavelengths of light. Chlorophylls are in the blue-green color and absorb red-orange light, and carotenoids are orange and absorb blue light.
So, using typical bulbs is...

Can metals be compressed? I've noticed that a metal coin can remain intact with distinguishable features for centuries even in wet environments but some metal things rust away very quickly.

I watched a video of how the US Mint made quarters and the sheets of metal they used looked pretty flimsy and flappy but after being put under a ten ton press those quarters are solid as fuck.

Does compression change metal significantly? Does it actually compress or do the forces just alter the metal?

I have asked a few questions here about smithing and such...

I know gold and silver coins can be intact and keep distinguishable features for thousands of years... because gold and silver don't really rust or corrode.

But I think I've noticed metal coins resist corrosion much better than other things.

It might be all in my head.
Nah, you can't compress solid metal. The main reason those coins seem stiffer than the sheets they are punched from is because they are a lot shorter. The extra length acts like a level and makes it easier to bend them. Shorten them up and they before harder to bend.

>the case will no longer fail

How are the cases failing? It's possible that your application places stresses on the servo shaft that the case was not designed to handle. So the solution might be to keep the plastic case and add a bushing, bearing or flexible coupling on the outside of the servo.
I never did any metal work.
There are so many things out there for milling, like CNC, doing it by hand, molding.
I just don't know how to make my prototype servo. Trying to think this through as much as possible before I start working on it, ordering materials and stuff.

Hello /diy/, I am currently soliciting ideas for a bike chain/cable/lock system that I could create from taking a retail model and further enhancing.

>Kevlar shroud over the chain and all under layers, loose hanging.
>Woven Kevlar sleeves that are snugly wrapped around the existing cable.
>Using multiple lockups/multiplying the time needed to cut through.

I live and go to school at a large flagship state university, and very recently the school has implemented a "Bicycle Registration" policy, requiring that all bikes kept on campus be registered with Parking/Transit services with a little sticker attached to the bike, recording the owner, model name, and specific/unique details of the bike.

For reasons unknown, they will begin confiscating all unregistered bikes found on campus, and from what I've seen they carry portable battery operated DeWalt disk grinders. I'd estimate 5" inch disks.

Instead of registering my bike to the school for no cost, I have decided to go full retard and make a political statement, protesting the very morality of why we should suddenly start registering our bikes in the first place, when bike theft has never been a major issue before. (Everyone locks their bikes up already, and the town is too small and doesn't seem to have any assholes walking around with hacksaws/cutter.)

tl;dr Want to make a bike lockup as painfully difficult and time consuming as possible for a regular sized road bicycle. Budget inside $200.

omg 3d printing stuff takes forever

I built my 3d printer in my office, and it has been running for the last 22 hours straight. I don't know if I'll be able to deal with this constantly, but I don't think I'm ever not going to be using this thing for a while.
I'm going to get hate for this but I bought into the 3d printing hype real early. Got myself a Makerbot CNC cupcake in 2009, did a few test prints, printed a object or two and the then extrudger jammed. It's been sitting on my shelf with a clogged extruder for years now. Just collecting dust. Should I try to fix it or buy a new extruder? They don't sell replacement parts anymore, there's little support for such an old model to try to fix it myself, and I'm not sure if I can get a new extruder that's compatible.

I've prepared a batch of mead must sometime around July 10th.

It looks opalescent with a little greyish-white yeast foam on its surface.
Is such a long fermentation time normal or did I fuck something up?

Id move it to a clean demijohn at tjis point and let it go through secondry fermentation. Long fermentation times are completely normal, so don't worry the longer it takes the better it will be in the end.

Also after its all bottled I recommendletting it mature for as long as you can stave off drinking it for, mead is fantastic matured.
