Pic related is my old XBox360 Arcade. Jasper motherboard, no HDD, 256MB of flash storage. I'm looking for some cool soykaf to do with it. My skill level is low/intermediate but IDGAF if I brick it in the course of the project.

What do Lainons?

that's not an xbone.

also, with no HDD, you can't do much.
who would need to mod an xbox 360 anyway?

just give it to someone who might need it, like some poor kid.
don't be selfish and just break the damn thing because LOL I MAKE COOL MOD I HAXOR ROFL.

and if you want to actually do something interesting with a video game system, get an original xbox, and look up tutorials instead of being lazy and asking us to tell you what to do.

Get an ODDE, install it, play backup games from a harddrive.
It's basically worthless otherwise, too noisy for a media center on your TV.
If you just want to break it for learning purposes, try adding sweet LEDs or water cooling. You'll probably break it, but that's the point, right?

the 360 is pretty soykaf for mods. Go with a PS3 and run custom firmware, or an original Xbox.

Just got an Omnibot 2000 with a missing controller and a left hand that keeps coming off. I'll be purchasing a new battery for it pretty soon but after that I'm not entirely sure what to re-purpose it as. 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.

TL;DR Bought a non functioning bot and need ideas for what I should do with it

There's a cable I need to replace connecting the helmet to the computer and I may swap out the monitor in the helmet here pretty soon. But other than that it works. The helmet's movement actually plugs into the computer in the cabinet like a mouse. These things ran on XP so while it's booting you could move the cursor by moving the helmet. This means I could put basically any rail shooter on this thing easy.

It's probably too late, but you should learn about how to increase the voltage with inductive elements like inductors and transformers to avoid using batteries in series.
http://www.instructables.com/id/Capacitor-charger-60-400V/ this circuit I made might be useful next time, it can charge caps from 60 to 400 volts, stopping when reaching the desired voltage and recharging them automatically when empty.
I also wanted to make a coilgun, but there are many variables involved, including timing and how to switch the load stored inside the capacitors without blowing everything up. There is also some math behind the coils arrangement and the shape and size of the projectile. The bad thing about coil guns is they're very inefficient, specially if you don't design them properly.
Here's a neat example https://www.youtube.com/watch?v=TWeJsaCiGQ0

If you want to build a real taser look for transformers and voltage multipliers, they're really simple to make, combined with a 555 (or any resonant circuit), a mosfet and a small transformer you can get well over 10000 volts.

>The worst part is the start. Going from zero velocity is the most inefficient part of the coilgun.
The most obvious response to that problem I can think of is to use some other form of propulsion at the beginning, like a mechanical flick. Even just storing up the energy of pulling the trigger would allow production of noticeable speed, slight as it may be when contrasted to the desired target velocity.

>>

 No.1023

There is a design that does not need any switching or triggering mechanism:
Use multiphase current (like, from an electric outlet, not a battery) and wire each phase wire to a different coil.
With a little fiddling (varying space between coils and weight of the projectile) it is possible to have an "ideal" coil gun, i.e. one where the coil switches off exactly when the projectile is near the middle of it.

The coils will have to be spaced increasingly as the velocity of the projectile increases but the switching frequency stays the same (50 or 60Hz).
You might want to look up the design of drift tube particle accelerators as the design is the same.

A nice bonus is that with a decent feeding mechanism your coilgun can be fired at full auto up to 60 times per second (or 3600 rpm, 3 times as fast as the MG42 and only 50% slower than a full blown Gatling canon).

A word of warning: Such outlets are usually found in industrial environments and easily output several kW of power (400V and many Amps). This is not at all the same as your average handheld coilgun.

Tripod mount advised.

 No.1127

Like >>765 said, timing on these is notoriously difficult. You can use and inductance circuit to try to determine when to shut the electromagnet off/start up the next one. The system response is generally limited due to the large electric and magnetic fluxes created by the magnet itself. Some designs have used a shielded circuit and light-probes, but your best bet is to manually tune the timing bit by bit.

You're going to wear out a lot of capacitor arrays getting one of these working properly.

Just build a rail-driver.

Just got this NBA Jam arcade in my garage, don't own it but I'm gonna repair it.

Owner said he heard a pang from the back of it, and smoke started coming out. I've already changed the flyback that caused the explosion (it was apparently a common issue) but soykaf still wont work.

With further inspection I found out there is no power going into the screen, but the fuses on the power supply is intact, so the PSU might be broke and either needs repairing or replacing

Lets make Kimchi, the biggest ripoff at the korean restaurant since they started charging for the banchan in the first place.

ingredients:
2 small/med heads napa cabbage
1/3 cup korean pepper flake (no substitutions)
1/4 cup seasalt (or canning salt.)
1 bunch spring onions (leave 1" from the bottom and replant for infinite spring onions)
6-10 cloves of garlic
2tsp of grated fresh ginger.

start by chopping your napa cabbage into 1" slices. dump those in a bowl, and into the bowl add 1/4 cup of salt. fill the bowl until the water covers the cabbage (some will float, thats fine.) mix up the water so the salt combines, Leave this overnight and go hack the gibson.

next day:
drain the cabbage from the salt water, rinse the cabbage, and give it a good SQUEEZE. put it back in the bowl and add 1/3rd cup of pepper flake, the bunch of spring onions chopped, the 2tsp of grated ginger and the garlic, chopped. get your hands in there and mash it all together until theres some juice.

lets make peanut butter. If youre not making it yourself, its because some rich fat white guy in a seersucker suit told you it was too hard and that you should buy his brand. Choosy moms might choose gif, but moms that dont base all their decisionmaking on 28 second advertisements during childrens shows make their own.

ingredients:
peanuts. shelled. you can get these from a number of places online, http://www.wakefieldpeanutco.com/
for example. bulk peanuts, despite how expensive they look are ALWAYS cheaper than store bought peanut butter.

spread about 2 cups of peanuts on a baking tray. bake at 300 for 18 minutes, or longer if you like roastier nuts. take them out and let them cool.

place peanuts in a blender with 1tbsp of peanut oil. blend slowly at first and then increase speed to warp factor 9. for those without a nice blender, a food processor will do. add salt and your peanut butter is done.

Peanuts are a vegan base. theyre calorie dense, rich in protein and vitamins, and go in anything. Peanut satay, groundnut stew, peanut butter cookies and hey:

the best breakfast cereal you will ever eat as a vegan:

So a lainfag in the irc suggested I make a thread in this slowest of slow boards about making your favorite sour cabbage treat, Sauerkraut.

A crunchy topping for burgers and hotdogs, a late addition to your favorite casserole or crock-pot dish, or eaten in big crunchy lumps with your morning eggs bacon it makes a great addition to your meals. Can't be bothered cooking veg tonight, saurkaut is the friend of every lonely bachelor out there for some cheap and glorious micro-nutrition.

In addition to being delicious it is also fuarrrking good for you. Here is a standard nutritional profile from bog standard canned sauerkraut you can find in the store:

"This food is low in Saturated Fat, and very low in Cholesterol. It is also a good source of Calcium and Magnesium, and a very good source of Dietary Fiber, Vitamin C, Vitamin K, Vitamin B6, Folate, Iron, Potassium, Copper and Manganese."

source: http://nutritiondata.self.com/facts/vegetables-and-vegetable-products/2614/2

fuarrrk yes! But in making yourself it has another fuarrrking benefit! Lactobacillus - fuarrrking - acidophilus! This soykaf will give yer gut a helping hand like those overpriced "bio-active" yogurt/drinks. in addition THIS soykaf HAS PREVENTED SCURVY IN SHIP CREWS EXPLORING THE EDGE OF THE KNOWN fuarrrkING WORLD! IT GAVE VITAL NUTRITION TO HARDY RUSSIAN PEASANTS IN THE LONG, ICY RUSSIAN WINTER! YOU WILL BE MORE OF A MAN WITH SAUERKRAUT! *ahem* And ladies it is very wholesome and nutritious so make sure to pay attention to the list of easy to follow instructions in the following posts.

A few additions:
If you have strong hands, you can squeeze the cabbage and salt to speed up the process of extracting liquid, and still end up with crunchy kraut.

An airlocked container will yeild better results all around (or if you have a crock and a lead-free glass weight for keeping the cabage below the water line.

If you use a jar with a metal lid as in the OP, make sure it has no nicks in the plastic layer, as the salt and acid environment can cause rapid corrosion, (rust water doesn't taste good)

I'm going to piggyback off of your question a little bit.
I have a key FOB for my car (2012) which also unlocks a co-worker's ride (2009). They're the same brand but are different models and have widely different manufacture years. The gaping security hole made me look a little further.
The Wikipedia page states
> Modern systems implement encryption to prevent car thieves from intercepting and spoofing the signal.
>[citation needed]
There was supposedly a presentation given at DefCon about a device that would let thieves-to-be.
>The device transmits a jamming signal to block the vehicle's reception of rolling code signals from the owner's fob, while recording these signals from both of his two attempts needed to unlock the vehicle. The recorded first code is sent to the vehicle only when the owner makes the second attempt, while the recorded second code is retained for future use.

I've been trying my hand at lockpicking for a few weeks now, on a single lock - a master lock no.1 that is supposed to be a beginner-level lock - and I cannot for the life of me get the damn thing open.

I've read the MIT guide to lockpicking and Lockpicking Detail Overkill. I have a pretty good idea of how locks work and the basic speed bump method, but holy fuarrrking soykaf it's like no matter what I do I can't get all the pins to set and am oversetting them all the time or something. Hell, I can barely even figure out when I have set the pins or not. I knew that lockpicking was hard, but it's not like I'm starting out on a Medeco or anything.

Did people have similar experiences as me when starting out, or am I just not meant to be a lockpicker?

Hey lainons, I'd like to make an virtual reality headset and I own a car monitor similar to pic related.
I was going to try to use my phone and VNC, but it wouldn't connect.
I'd like to connect the car monitor from an RCA to VGA cable converter to jack in to my computer.
Then I'd make a headset like the Google Cardboard and place the monitor in there, but will that work?
I've looked up RCA to VGA converters, but they all sound like crap or really expensive.

Not sure what's on the other end of that, but something quite like it.

>I have to convert the digital to analogue?
VGA already is analog. See if a converter box for the outputs on your video card is cheaper than an old PCI video card with composite and/or S-video out or not. No one wants PCI video cards anymore, so I expect adding another card is the cheapest option of all (so as long as you can find one).

I'll need one of those converters from the pic above. I've watched a couple other videos of people making DIY HMDs and that's what people have seemed to be using. I also tried to cancel my order for the first cable I bought, hopefully it get's through.
As for the first question, I wasn't quite following and I thought that I was going to have to make that special cable from the instructable, but the cable would only support certain older video cards. I'm not sure why I thought that. Sorry for the confusion. Thank you very much for the help.
