TOYS with LED's

Hi, I recently bought one sword with LEDS and I want to know how they control the LEDS (it have different patterns of lighting). They use a PIC or IC ? I open the sword and have a very small PCB board with the IC cover with a black solid coating my questions are: The toys use and IC or PIC? What is the difference between IC or PIC's? They control also the voltage of the LED (different color of LED have different voltage)? The PIC/IC is programmed in which language? Where can I found more resources about this topic ? thank you for any help Chris SWORD http://www.rinovelty.com/index.cfm/fuseaction/products.thumbs/cat/114/page/2/filter/pricerange%7Cany%7Cany/Light_Ups_Light_Up_Swords

Where to get latex foam

This is sort of a follow up of my past question (https://www.instructables.com/answers/Good-foam-to-make-swords-out-of-nerf-sword-style/). I think I know what kind of foam I need: latex foam. Now I need to know where to get it, though. Anyone know? Home depot? Michaels? Amazon? Some specialty store online?

Good foam to make swords out of, nerf sword style.

I make recreational weapons as a hobby, and as a (sort of) job. I like to sword fight with my friends (especially percy jackson capture the flag style. Yes, I'm that geeky), and my theater company also needs swords for our acting. I had two decent swords already made, with custom, homemade cardboard frames covering and these awesome plastic dowel things up the middle to give it strength (though the dowel has just the right amount of flexibility as to make the swords realistically bendy). It was a great design until the show came around, and I spent each morning before going onstage fixing swords. Now, I will make this very clear: making swords is fun; but rushing to fix them before going onstage misses my idea of a good time by a mile. And don't get me started on fixing them backstage. So understandably, I modified my idea. I have it all planned out, very simple: one of those godsend plastic dowels (I think they're really wire holders or something, but the package wasn't clear) stuck up the middle of a piece of foam carved to look like the blade of a sword. The only thing I need now is to figure out what density, and what type of foam to use, and then where to get it. People need to be able to hit each other with the swords fairly hard and still not get hurt, but the swords need to stay intact too, and they need to keep their shape. It's acting, so I can't just use boffer swords. Long story short, I'm looking to make a nerf-sword-like sword, but I need to know what kind of foam they use to make nerf swords. I'm looking, preferably, for a type of foam that comes in a block, or at least board form, so that it's easier to carve. Any ideas, fellow instructablers?

Awesome Things to do in Halo

Hi there, fellow halunatics. In this forum, you can post awesome things that you have done/seen done in any of the Halo games. Other games are not welcome. Anyway, here I'm going to list some things that are just downright awesome to do. Keep in mind that over the course of time I will continue to add to this forum. - Facial grenades. When you go up to an enemy and stick a plasma grenade on their face. This practice is funniest with a Grunt as the victim. - Headshots. Especially badmirable when they're moving and/or you hit your foe in the face, as this is just awesome, and it usually makes flop around in a comical manner. - Keeping the energy sword after you run out of charge so that you can punch people. Hilarious with Grunts, as their faces are just at the right level for your fist to pound on them. What a happy coincidence >:D - Bullfighting/toying with Hunters. Safest in Halo 1;  Hunters can't swing behind them. - Playing on Legendary without dying a lot. If you can do this, then congratulations, you are good at Halo. - Killing a Grunt/Elite just as he's about to throw a grenade so that it lands next to him and blows up his friends. A real Master Chief moment. - Not dying. Life is regarded by most people as a healthy practice.  - Ninja Mode. Sneaking around an area (possibly with the help of active camouflage), killing your foes without firing a single shot. Extremely awesome if an entire area can be successfully cleared in this manner. - Energy sword/gravity hammer kills. 'Cause they're just awesome. - Splatter kills. Shows that a) you know how to handle a vehicle well, and b) you are confident enough to get that close to your enemy to kill them instead of shooting them from a distance. - Boarding. Can't do it in Halo 1, but its still awesome.

Electric knife sharpeners.....

Back in the day we already had these tiny grinding wheel like tools in the kitchen.Plug it in, press a button and slide the knife through.The blade was supposed to come out razor sharp if you trusted the ads....For obvious reasons a grinding wheel moving along the edge is not a good thing, especially not if both te up and the down movement work on the edge.As soon as they appeared they disappeared only to emerge years later in a "modern" form.The latest incarnation now comes with ceramic wheels to give an even sharper finnish LOLThe problem however is still the same, first the action of the whells then the fact that it is next to impossible to get different angles.They are really only good for some knifes you use in the shed if nothing else is available.A now much hyped electric sharpener is basically just a tiny belt sander with guides attached to it.And don't get me wrong, they come in handy for certain works.But if you ever used a belt sander on a flat piece of steel you realise that it is quite impossible to get a flat surface finnish.The belt curves around the edge and this results in a curved or beveled edge.Obviously the claim to sell these is that a beveled edge has superior strength and sharpness compared to a straight angled edge.And then there is the ability to adjust not just the sharpening angle but als the grid of the sandpaper.The finer you go, the better the result and sharpness...Now if we trust those who create swords from raw iron ore then something is wrong with the belt approch.These guys would tell you that you should always use a flat stone and to slice a piece of the stone.But also that a beveled edge is a sign of wear, something a good butcher will confirm.The angle of the edge party affects how sharp and durable the edge will be.Usually there is a compromise between blade thickness, meterial and edge angle.Just go from razor blade to an axe and include severel types of knifes between them.So a beveled edge in my opinion is only good for brute force tools but not that good for fine slicing and dicing.I tried to sharpen a wood chisel on one of the belt sander toys...It turned out to be far less precise and the edge was not fully straight.Could be down to lack of experience but if you ever try it let me know your results.The produced edge was also quite unusal and often bad when used as intendet.Far more chipping than cutting.Difference between straight angle and beveled angle when using a knife.You might want to do some lonely woodworks while fishing.A good knife now just eats into the wood and lets you cut and slice pieces of at almost any angle of the blade.With a beveled edge however you face the problem that your working angle is drastically reduced.Tilt the knife a bit too much and you suddenly just slide off the wood and into your flesh.If you grind and hone a knife to a 20° angle on a flat stone than from all angles above 20° you can cut.If you belt sand a knife to a 20° angle you end up with a bow over this angle.The actual usable working angle can be as low as 40° on a thicker blade.In theory it is possible to overcome this bevel problem.Sanders with a backing plate for example or by using just enough pressure to take material off.The first will destroy your belts quickly, the second takes forever.Some people just sand the knife at an angle to the belt, so instead of having the belt running at 90° to the edge it runs at 60 or 40°.Reduces the buckle but also the sharpness as the actual edge is now rounded.The only real way to sharpen a knife would be with a cutting or slicing motion, something that usually cuts your belts once the edge becomes sharp enough.So should you use them after all?As with all tools it comes down to quality and how you use the tool.If you know what you do and what the limitations are an electric sharpener can save you a lot of time.Someone with a desire for razor sharp knifes and tools might only use them on the lawn mower...You can however very well use sandpaper for sharpening a knife, which I will explain in another post....
