256 KB,
So, /diy/, I'm not sure if this is the right place to post this. /cgl/ probably has more expertise with the skill, but who knows what I can learn here.

So I want to make two stuffed animals. A teddy bear that's 6'4", and probably another 15"-22" teddy bear. The huge one is for me, the normal-sized one is for my cousin.

I have two sewing machines in the basement, but I don't know how to sew. On the plus side, I think both of my parents do. So on that point, maybe I won't have a problem. Do you guys know where I can find patterns...

No. I wasn't going to say why because I was afraid it would be too "degenerate" for any of you to want to help me, but if you guess something that degenerate I may as well come clean.

I'm a 5'10" tranny, and I've been feeling lonely as fuck since I started taking hormones. That's the reason I want to make myself a teddy bear to cuddle with, so that I don't feel so alone and unloved. That's the reason I decided on 6'4", because it's roughly the...

my dad does. basically the part you're talking about you need to either make or buy a jig. you predrill to the correct depth and then route it with the jig with a plunge router (is that what it's called?).

I happen to be building an acoustic for my first time right now. I personally started with a full scale blue print, made a simple mockup with a wooden railing, and went from there. There's just so much I could get into though about building. Maybe following someone else's build in a blog...

Find a template for the outer shape online that is to scale. Either find someone with a printer big enough to print it at scale or use something like BigPrint to print it.

Use a band saw or even a jig saw to cut out the rough body. Finish by sanding down to the exact shape and outline.

https://woodgears.ca/bigprint/help/tutorial.html#inksaver

As for cutting bout for wiring, picups and controls, this is mostly covered by plates and shrouds so it shouldn't be such a hang up.

If you did want to use a router and template just follow the exact same process.

I know some of them can be turned off in software, but the power LED and I think one other LED can't be turned off that way.

Hey diy people - first time posting here so sorry if this is the wrong place to ask. I currently have two sensors (HIH6130) with an arduino UNO - plus an LCD. I can get the first sensor to get the humidity and temperatuer and display it, but i have no idea how to get the second sensor to start working, I've hooked it up to the arduino, but I can't make the code work. Help me out please!
Here's the code: http://pastebin.com/c7whSpzp

1) To clarify what it is you are trying to do: what you want is to have two of the same kinds of sensors hooked up at the same time? And to be able to read either one of them?

2) Are your sensors I2C ones, like these?--

>HIH6130 hih6130(address); //EXISTING STATEMENT
above is the way you would do the basic code.
in that statement, the "HIH6130" part is the class of the object you are creating, and "hih6130" is the name of the particular instance.
you can name the instance anything you want, as long as each instance has a unique name.
So you could do like this instead:
>HIH6130 sensor_1(address_1); // this is the first sensor
>HIH6130...

They have a positive and negative terminals on opposing sides but I don't see a voltage marker anywhere on it. Is this a battery? and if so that would be amazing because its so flat

Could be a high wattage resistor. Use a multimeter, check it for voltage, if nout, check it for resistance.

Resistors are not polarity sensitive anon.

Could be. Could also be a fuel cell. It appears to have some sort of nipple on it along the edge which could either be a gas vent or an inlet/outlet for electrolyte. Is there another nipple behind your thumb or on the opposite edge? Does it feel heavy like a battery or hollow? Does it sound solid when you flick it with your finger?

Hey, /diy/, I've got a question.

For an electronics project I'm using an ABS plastic enclosure. I've got a nice handheld drilling machine, but no saw.
I need to make some holes in this material, I can do small circular holes with that drill.

But what for kind of drill bits do I need? Are wood drills fine? And for square holes, I was thinking of making four circular holes but I need a saw to do the rest. What kind do i need?

Wood bits will be fine on abs.

For a square hole I would either use a file and file the corners of the drill hole square, or get image related.

>>935894
The square holes are quite bigger than what most drill bits can do so I was thinking about a small saw like a fretsaw, but I think those saws are too thin and breakable to get through plastics.

I will look for those kinds of saws at the hardware store tomorrow.

I just got home from work, inserted my key to unlock the front door, twisted the door knob and the knob came off. I entered through the back door and removed the knob from inside the house. The photo shows what is still keeping the door from opening. Any ideas how I can get the door open? I tried sticking a screwdriver inside that big opening in the middle and forcing the latch open but I'm either not strong enough or it doesn't work that way. Any advice before calling a locksmith would be appreciated. Thanks

Where the fuck is your rotating latch mechanism? Show the part on the doorknob that is supposed to fit in there.

>>935989
These two protrusions attach to the latch and are actuated by the handle. They just get pushed backwards away from the door jam to retract the lock.

Theoretically, is it possible to build an electromagnetic pulse weapon which would first accumulate a huge charge, and then fire it at some device, frying the electronics of the said device or at least disrupting it?

Is it possible to build a very low-power prototype which can be transported more or less easily (at least to an extent)?

I'm wondering because I found this shit:

You're not gonna like the answer but the only way is to sand the door, bonds the dent, and repaint the door. Unfortunately there's no 'unbending' bent metal.

14 KB,
It's my first time with LED's and I am a complete noob on electronics. I want to make a circuit, pic related. 12 rows of 3 leds. I have a 12 V battery pack and the leds are with forward voltage(V) min 3.2 and typ 3.4 and 20 mA.

What I can't figure out what resistors to use, because all the info I found on wiring leds was only with parallel or series and I am confused what to do if I have this mixed circuit where series of 3 are wired parallel.

>>
>>934027
Each branch will get 12v as they are in parallel.
Voltage drop across the resistors = 12 - (3*3.4) = 1.8v
Resistance = Voltage/Current = 1.8/0.02 = 90 ohms

Of course, since you're using a battery the supply voltage will drop slightly but it shouldn't be much of an issue.
>>
>>934027
You just calculate the resistor for one of the series arms, then put as many as you like of these arms in parallel.

Exactly like in your circuit diagram.

You don't need any extra resistors, just the ones that're already in the serieses.

Oilskin has been used for at least a hundred years now to keep out wind and rain.

The next thing from that would be chemical resistant gloves, which are basically just cloth gloves dipped in rubber. These would probably feel as cold as leather in the wind.

Every video I've seen about sawstop shows the finger/sausage sloooowly approaching the blade to demonstrate the brake, and then it shows the intact test subject. I've been wondering: what would happen if you straight up slapped the blade or hit it with your hand at a higher velocity?
