Hey /diy/, /an/ here. I have an LED fixture over my reef tank, and wondered if it would be possible to create/buy a device that will slowly make my light brighter throughout the day, peaking at noon, and then going back down slowly til nightfall (basically a dimmer setting on a timer. They have things like this already called apex controllers (other brands but thats the biggest) but their fuckin expensive, and i always prefer to do it myself. Anyone got any interesting ideas? Pic related, my reef.
What are some good materials I can use to insulate heat from standard metal vise jaws that won't melt or burn from very high temperatures, but will hold up under clamping pressure? This is to prevent the entire vise from acting as a giant heatsink when heating parts with a torch.
Ideally, it would be an insulator with the ability to hold up under temperature like ceramic, but can yield under pressure and is tough, like rubber. Basically, is there such thing as rubber that won't burn?
So I have a heavily modded original Xbox v1.1 mobo with executer 2 chip and lcd front panel I made about 10 years ago. Custom paint job clear case with air filters and USB ports totally turned into a piece of functioning art. Now a days the processing power of this Xbox fits in your pocket, so my question is what to do with it. It still runs Xbmc and everything functions it has a pretty complete history of console and arcade games, just taking up too much shelf space. Wat do
>>950162 That would not get me off, but if I wanted to fuck this Xbox I would tape the controller to my penis and perform a vibration test, I posted here because I thought people could ask me build questions if they wanted to know how to mod a original Xbox or something along those lines, I am sorry if I offended you or something but you seem a little butt hurt mad
>>951634 Right of the bat I see the "Art Commision" box has the text tilted too much to the right side.
The "my comics" is decent but I would like a function that would allow me to go all the way back to the start
The "art commision" section is ok, but there are empty boxes in between some of the choices.
When I go under "my art" it shows a slide show, from my perspective, I would be more interested in a bigger gallery of pictures so I don't have to scroll through... Comment too long. Click here to view the full text.
Would a design like this withstand a 350lb man flopping down on it? I want to build my Dad a new bed for Father's Day but he's a pretty big guy. What if I doubled up on the bottom 2x4s and then used 2x6 slats instead of those skinny ones? I have absolutely zero /diy/ experience but I'm just a broke 22 year old.
If you're serious about building the frame with 2x4's then put them on edge AKA skinny side facing up for added strength. or if you wanna stick to the skinny slats (like in your pic) then make sure you beef up the middle support. probably should be ok just by doing that.
Hey /diy/ers, I'm looking to build a circuit to control and drive high-power single LEDs. I'm looking at LEDs with stated 1A maximum currents, but looking to build a circuit that can provide sustained operation at up to 1A, as well as pulsed operation at up to around 10x that (pulses of a few ms, so with an adequately low duty cycles I should be able to operate well over max specs for the LEDs without burning them out).
The problem is, I have no real knowledge of electronics beyond basic V=IR fundamentals. I'm trying my best here, but it's quite... Comment too long. Click here to view the full text.
>>950983 1a. There are things called digital potentiometers. 1b. If you just need few bits worth of control, you could use some mosfets to pull one (or more) of several RSET resistors to ground. 2. Yeah, a computer PSU would be an easy solution. Dunno what's wrong with your search terms, but you could check some big distributor's like Farnell's catalogue to get an idea what is available - assuming you aren't happy with PC psu. And then optionally buy shit from elsewhere.
>>950989 >>950990 Thanks guys. I've looked at a few digital potentiometers, but they all seem to either have increment/decrement control, or are controlled by serial protocols that I don't really want to code into my instruments by hand. If I want to be able to call $SomeResistance from parallel outputs (4-6 bits would be fine), what's my best option? I could probably use an arduino to translate to I2C, but are there better options?
i heard a story this weekend that some madman left home only to be homeless for a tad , so he lived under his brothers bed . At night he would steal foodstuff and the like since his pa was a drunkard. He would sneek in through the window, and when everyone went to work n school he would sleep under the bed
i went to cancun years ago, stayed in one of the older shitty little villas, probably nice back in the 50's, but anyway, one of the maintenance workers lived under the stairs leading up to one of the rooms. surreal looking in there and seeing all his stuff. he had pet iguanas everywhere.
I recently used a raspberry pi v2 in my computer architecture course(because MASM doesn't really let you get that low level anymore), and now i'm wondering what I should do with it, now that the course is over.
Does /diy/ have any project recommendations? What should I do with it?
The first inclination that people generally have is to turn it into a media server. Plug in a usb hard drive, and either connect to wireless or Ethernet. This is never a good idea because the pi only has a single channel usb and the Ethernet port is going through it so every communication with need to go through the same usb channel 2 in order to get there even on a fast Ethernet connection in practice i had trouble even streaming 480p video from one.
Best use is to use it... Comment too long. Click here to view the full text.
My sink has been broken for awhile, it often pops out of it's mount because one of the screws in missing and the only other screw's mount is snapped. The one screw left is a bit stripped but even if I got it out there's not enough room to get in to screw it onto the other side.
An idea discussed in >>>/biz/1106359 led to the idea in pic related, which I'll describe in detail since I am terrible with a pen.
The idea is to dig a lake which mostly lies only a few cm below sea level (it would curve downwards towards the middle), so that water evaporates rapidly, with the intention of increasing local rainfall.
This lake would be connected to the ocean by an overground channel and an underground tunnel. As water evaporates, the overground channel replaces it with seawater,... Comment too long. Click here to view the full text.
>>950962 There's nothing wrong with it at a fundamental level, but in practice it may be difficult to achieve adequate circulation with density/hydrostatic pressure alone. If the flat in question was located right on the coast then sure, but over scores of km to get to an arid inland location in need of hydration, a few cm isn't going to cut it. Free-flowing aqueducts generally have gradients of 1 in 5000 or steeper.
Also, basins that are below sea level (where such a proposal would obviously be located) are... Comment too long. Click here to view the full text.
I suppose a cheap, easy solution would be to paint the back and lower portion of the LEDs black, so that none of the light shines into your eyes. Of course, your vision would still be somewhat obstructed, but you could still see enough to avoid walking into things.
>>950323 To be honest, probably not. LEDs are cheap, easy to work with, and most importantly lightweight, perfect for something worn on the head.
Of course, if you were only displaying a static pattern, you could fill the non-lit parts with some appropriately coloured plastic film, such as the type used on lamps/projectors. That'd let you see straight through the majority of the visor, and could still look pretty good, as long as you picked your colours right.
