Ok so i am making my own gym in my garage. There is one wall which is 2x5 meters. I want to paint it or spray all over it to make it loook good. Problem is i am really bad with painting. So any ideas on how guy with zero painting skills can make the wall look decent ? Ps i thought smashing couple ballons with paint on the wall can look good what do you think ?

Is it possible to power a usb device from the power board on a monitor? I know there are monitors with usb drives, but I cannot find one for super cheap.

I want to make my own furniture for my home. Im looking for ideas for materials/construction techniques with regards to sturdyness. I want strong shelving, a bookshelf, an entertainment center, a nightstand, a bedframe.

But my first project is a general desk/work table. Suitible for office use such as a computer, reading, writing/drawing, as well as workshop uses (re)building, repairing anything i need. A lot of pics i see have crossbeams all the way around the bottom, but i need to leave one out so i can slide left and right with my chair.

I like dark, but honestly this is a trial run to learn the ropes, so i dont want to get super expensive if i dont need to. In a few years i can do a better set for a new home. I have a decent tool set and can buy what i need.

Not sure if this belongs in /g/ or /diy/.

How do I achieve one of the situations in pic related.
Basically I just want to listen to raw data purely for entertainment/interest purposes.

So far the plan is something like this:
>Capture data with wireshark
>somehow import that data into audacity
>export as mp3
This would not be realtime tough
another way would be
>disassemble microphone
>solder one end of CAT5 cable to mircophone
>plug microphone into PC
>record with audacity
>playback at same time

Any solutions or people that can help me? What kind of encoding do I need to use to import raw data in Audacity? What should the byte-order be? what about the sample frequency?

Hi /diy/
Premise: I'm a complete electronics illiterate. Basically I need a device that will discharge 2x AA batteries (in series, so 2.4V) at 3A, with cutoff at 1.8V. I already have a battery charger for my RC but its max discharge rate is 1A on NIMH batteries, and I don't want to get a new one because money, plus it would be fun and I could learn stuff.
How would I go about building this? Would it be expensive? What parts do I need? Is there some stuff I can read? I can do basic soldering, I built a basic battery holder with banana plugs to connect to my charger (pic related).

If math doesn't fail me, discharging 2.4V at 3A means I need a 0.8Ω, 3.6W+ resistance? Can't find them anywhere though.

Basically I want to drink wine out of a human skull. How would I go about making a bronzed bowl safe to eat and drink from?

Hey DIY, I wanted to know what some festive things I could do around Halloween this week.

I have a Commodore 128D and a keyboard for it but the cable has been cut. I have searched the web for a wire color pinout but had no luck finding one. I found this: http://www.ntrautanen.fi/computers/hardware/misc/128_keyboard.htm but it doesn't tell the colors for the wires. If someone knows about the wire colors and pinout I would appreciate you posting it here, thanks!

Hi /DIY/. I was wondering if you can offer a little advice on my costume. Basically I'm doing a classic robot, complete with cardboard boxes and that flexible aluminum tubing (basically like pic related). I'm building a couple of things to make it a more realistic robot, eg flashing LEDs, robot voice box, etc. I want to include a couple of motorized functions, which is where I need your help. I already have an arduino uno and two motor sheilds.

First motorized function is to make the head spin all the way around. Keep in mind this is basically just one cardboard box spinning on top of another. How should I hook up the motor? Is there some sort of material that I can use as a gear around a neck, or should I figure out how to 3d print a big old 10" gear, or what? I measured, and it turns out I need a 10" collar to be able to fit my fat head through it. Also, is there some kind of bearings that I can use to help it spin, or how can I mount the head to the body so it can spin freely? How strong of a motor am I going to need to spin the head, assuming it weighs, say, 2 lbs and has friction of cardboard against cardboard?

Second motorized function is just to open a small door on the front of the robot. I have a small metal fuse box that I'm going to mount in the front, and I'll just need the motor to open the door with a lever or something. Any advice on how to gear something up so that the motor, which spins, can move a metal plate through the motion of opening it? Sorry, but I'm just not a very mechanical person, and I just cant visualize a simple system for opening a door through a 90 deg. swing. Should I use a linear actuator that pushes at the top of the door? how strong would it have to be?

Sorry if these are trivial questions, but I'd appreciate your help.

can someone who is a welder or know how to weld tell me if this is a good weld? i have just started welding and i need all the advise you can give. pic related its my weld
