With my mind on something else I very very stupidly(i KNOW I KNOW)put my almost brand new iPhone 4 into the washing machine. Its been drying for 3 and a half days but still wont turn on. My new plan is to put it in rice,leave it in the airing cupboard overnight and try plugging it into my laptop in the morning. Any other advice?

I find it all to easy to bog down my 4" table saw, causing the flimsy belt to run off the pulley. I'm thinking I need to change pulleys to increase speed and, ad a stronger/thicker belt. Any feedback out there would be appreciated. Hubiewan

Ok, so I made some mods to my AR-4 v3. There are 3 major mods, a couple of other minor cosmetic mods, and one performance mod. Picture 2- minor stock mod. This mod allows people to extend their stocks to make it longer. Picture 3- New hopper based off of Killerboy's removable mags. Major mod. By using his hopper as a fixed mag, It now allows me to hold 9 yellow rods, which is pretty big. It does jam, but rarely. The rounds will all stay in the hopper if you vigorously shake it, and you can remove the rounds pretty easily. Picture 4- Minor trigger mod. All it is is replacing the hinge with 2 Y connectors, a white rod, and a purple one slot connector. Picture 5- Scope mod. This connects the scope to the top of the gun, making it a better hand grip for carrying. Picture 6- Yet another scope mod. This mod was made to adapt to the new fake barrel, which was filled up instead of only the middle row having the orange connectors. Picture 7- Mod to the bottom of the gun. The last one was just having blue rods, this one fills it up with connectors. Picture 8- Foregrip mod. This is the second of the 3 major mods. I did away with the bipod and modded the bottom to have a new grip. Mainly a comfort mod. Picture 9- Barrel mod. The last major mod. This mod was made after several people noted that the ammo needed some 'Help' to get into the barrel. I basically just filled in the hollow area where the ammo would jump from the hopper to the barrel, so you dont have to stick your finger in. Picture taken from top of gun. That stuff above it is what you connect the scope to.

Posted!Do you think this gun makes the AR-4 v2 look like a noob's toy? plz answer!This is a new bolt-action knex assault rifle I made. It shoots Yellow rods. This gun is the first bolt action to my knowledge that doesnt use modded part.For those of you who dont think it is true bolt action, to shoot the gun, you have to pull the ram/bolt back, then push the bolt back while leaving the ram pulled back.STATS-Bolt-action-True trigger-includes bipod (foldable)-tight looks-includes scope-6 round hopper-30-40 foot range (one rubberband doubled up)-Safety (new)EDIT- I have put tape on the part of the bolt that pulls the firing pin back, and it gets an increased range. the tape straightens the parts that hold the bolt, decreasing friction.This started out as one of my failed projects, I made it before the jackal and showed it to ajleece and some others. The original one had a bottom loading removable mag, shot blue rods 5 feet. I took it apart to make my jackal, and then I got the idea to make it a true bolt action.I was not trying to compete with the ZKAR, I was just trying to make my AR-4 v3 work.Here is a video of me firing it on youtube:

I have a double, 4-poster bed. The posts unscrew from the headboard and footboard. And the finials on top of the posts also unscrew. I want to make a bed with curtains on all 4 sides. Kind of like a canopy bed, except with no top. Only the long sheers on all sides. These can hang from rods. The problem: I want to attach the four rods, preferably very thin and light, from post to post to post to post to post. I prefer that the rod be stiff and not something that would sag with the weight of the curtains. Of course the curtains will be lightweight sheers. I have searched for a kit to build. Nothing comes up. Any ideas?

How hard would it be to make a metronome with 4 leds. I don't care about speakers. There are projects like that in instructables and youtube but they're all 2 leds and a speaker. They go 1-2-1-2-1-2-1-2-1-2 I want it to go 1-2-3-4-1-2-3-4-1-2-3-4 it would be pretty cool with different color leds. What would it require, probably similar materials to the instructables, but less cause there is no speaker. How would the circuit look like?

So i have an 1998 dodge ram 1500 i purchase with no power options at all so i got power window regulators and replaced the door panels and bam I've got power windows. and since the door panels had lock buttons i bought some cheap 12v actuators off eBay and wired them up and bam. power locks.. THEN in all my creativity i was like i'll just buy an RF 4 channel kit and make it key-less. so i ordered this kit not realizing what type it was http://www.ebay.com/itm/320783435624?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649#ht_2920wt_1185 to summarize this kit requires you press one button to activate the a channel and press a second button to disable the active channel.. not at all what i was looking for. Is there any way i can convert the kit i've already paid for into a momentary style. so as long as i'm holding the channel button down its active. ???? here are all the chip/ component numbers. 4x SRA-12VDC-CL 1x SC2272-L4 - BD25D5D1 1x 9530FH~~~~~~ unreadable some residue on the chip a few caps a few resistors and an LED.. anyone think this is doable or should i just shelf it and get a diff kit?

Hey, I'm not understanding something here. If I hook up a pot (left 9v, middle A0, right GND), I get a varying voltage into pin A0 on Arduino. Then Arduino converts this into whatever. Well when I hooked up 4 potentiometers parallel to the same battery, and had them on pins A0-A3, none of the pots worked. Whenever I turned one pot, it would change the value for all the others (i was using serial monitor). How do I correctly hook up four pots to Arduino?

Huzzah! I would like to thank the poeple who viewed and commented on this forum for the first 4! Thanks! Anyway, I am hosting a Forum Topic train. This one involves some thinking. But it's not math! It's the fun thinking. The kind you can talk and laugh about. So, what do you say? This week's Thought Bunker: If you sneezed on a computer, would it get a virus? Well, what do you think? Tell us! This weeks Best-Thought: Nov 28, 2009. 8:39 PMstarwing123 says: Depends. If the computer was biological, like they may be in the future, yes. With current computers, it depends on your definition of "getting a virus" If getting a virus means infected and damaged by it, than no. If it means carrying that virus, yes. This is of course, assuming "you" is a human or other biological organism. If the "you" in questions is a sentient computer or AI, than the computer would get the virus because the "you" sneezed a virtual virus. Then of course, you can go into the combination of the above examples, like a biological, sentient computer or robot that looks like a human. Wait, wouldn't that be a human?

Well, here's my first attempt at making my V4. It's packed with features but unfortunately it isn't reliable yet so DON'T BUILD IT! I'm probably going to end up having to totally modify it to work so I wanted to get a picture before I ended up destroying it without hopes of getting it to work. Anywho, I don't care for block pistols but after giving it a shot, it's much easier to incorporate things like a pinlock this way. I'll start listing off the features because I don't want my entire picture to be comprised of yellow boxes. Starting at back working to the front: 1. Uses a new pin concept that I've been working with. There's a red connector connected to the pin, and then the yellows are connected as show to absorb the force. In theory, this should mean that because the force isn't transferred to the connection of the pin and the band holder, it shouldn't require any sort of other force suppressors to keep the pin in. However, it does make a loud clap so I'm probably going to try adding rubber bands around the connectors (but not around the pin) to quiet it. 2. I finally added a pin lock. I'm bleh on it though as it requires a broken orange in the barrel (I just have these pieces "naturally' so I figured most K'nexers would) and a band to ensure it works, but it works nonetheless and it adds almost no friction from the way it's on. 3. I stole KSC's idea for wheels. I'm not sure how much it'll help but I figured, eh, it doesn't hurt. 4. It uses the bullpup trigger idea from my PDR so that I can have a more compact weapon with good power. 5. The handle is from my new UMP and was added to give a more comfortable angle. It also is three layers with no white rods needed. It's decent as far as comfort goes. 6. Finally, it has a tilting mag that's right in front of the handle, so it's easy to access. The problem is I need to make a better pusher and figure out a lock for the new pusher. I think the barrel is part of it because I went back to the old blue rod style. The gun isn't reliable at all. 7. Oh yeah, almost forgot to mention that I'm experimenting with adjustable sights. I didn't make adjustable sights for this gun, per se, but rather I added multiple folding sights that are at the same height, taller than the front sight. This means that the closer the rear sight you use, the more of an angle the gun has. I doubt this'll be useful at all but there was room so I just threw them in there much like the wheels. And that's that. The feel of the weapon is pretty nice. It's balanced. But yeah, that's all I've got to say.

I was looking back at the old K'nex war log posts. I saw people criticisim and know I understand how I should do it. This one, is for everybody. 11/23/10 The war has been going on for some time now. It hasn't really captured the world's eye yet, but it will someday. To date, the death toll is only 3, but the injury toll is 256. Many outsiders have been recruited, and they are usually the main injuries. 1/23/11 The leaders of both armies have agreed to join forces to take over a rising power... the Lego gunners. Their army has never been a major threat, until now. They recruited 1,000s of people, from far and near. Most people say they are easy to take down, but I don't know. 2/12/11 The first few battles have been fought, and we have been winning, but something amazing happened. To be continued...

I am trying to re-flash and put linux on this mp3 player. The ultimate goal is full sound and photo/video support with touch screen interface, using an alternate OS other than the one provided by polaroid. I would like to use this to read text documents as well. ---- --- I was going through some of the old gadgets in my house and found that I still had an old polaroid pmp350 mp3 player. It has a touch screen and I thought to myself "hmm... google android..." or "rockbox..." This is a cheap peace of hardware, and even though google android is out of the question, I was wondering about flashing it with custom firmware to allow it to run some other operating system. It has a touch screen which would make it quite fun to play around with if only there was a way to expand its current capabilities. So I thought I would put up this thread to see if somebody more clever than I could figure out how to re-flash this thing and install linux, OR if somebody could point me in the direction of materials that might be used to do such a thing. The main issue is going to be getting an OS to run on this unsupported hardware. I am going to be doing research in the meantime to find out how to get linux on this device, because I think it would be a really cool hack to show off to friends. *Update* Have written polaroid for info regarding technical specifications, also asked if they might be able to provide a rom flashing tool* If anybody wants to give this a shot, let me know how it turns out. Peace and love.
Question by djbuggybee | last reply
After reading knexgeek's review, I decided to build the ZKAR to see what my AR-4 was being compared against. I can't do a side-by-side comparison because I ran out of green rods. Anyways, Here are the advantages of both guns over the other. ZKAR advantages over AR-4 v3: -ROF -Size (smaller, but weirdly uses more parts than the AR-4) -Comfort -Better trigger -Yes, I guess it does have a nice, clean design AR-4 v3 advantages over ZKAR: -Range (gets a slightly better range than ZKAR with an equal amount of bands, around 5 feet better) -Reload (While you can easily slip rods in at regular intervals on the AR-4, I find it a bit difficult to keep the ammo in before I put the pusher in on the ZKAR) -Sturdier than ZKAR (I find that some parts on the ZKAR break after heavy use, while the AR-4 v3 is just fine) -Farther pin pull Now both guns have their flaws, Let's just list some of them: ZKAR flaws: - The back wall on the mag closest to the trigger can break off. However, it's a good note that the bolt always touches that back wall so I guess it evens out. It has only broken once when test firing. - If you somehow pull the bolt back and push it forward twice, you find that it can jam and it's a pain to get it fixed. - Sometimes the bolt breaks. However, to be fair, it only broke during ROF tests. AR-4 v3 flaws: - Can't be loaded upside down (I don't see this as a major problem, and you can shoot the gun upside down, but idunno why you would wanna) - Sometimes the bolt doesn't go into the chamber without "Help", but then you can just stick your finger in. - A few times, the ammo completely misses the bullet lock. This is rare though. So I guess that's my comparison. I do like the ZKAR and it does live up to it's rep, but I think it's all an even playing field with each gun having it's own uses on the field. While I'm at it, here's a ZKAR v2 review (I know there is another ZKAR review, but that was for the first version) Body structure: Stock: 9/10. Why: very sturdy and comfy Handle: 7/10 Why: Sometimes pinches your hand Trigger: 10/10 Why: Very sturdy and original Body: 9/10 Why: sturdy, but a bit hard to build Mag: 7/10 Why: Small chance that the rear mag wall will break off (that has only happened once to be fair) Bolt: 7/10 Why: Works, but the bottom part that pushes the ammo up to the barrel can break after heavy use. Overall: 8.1/10 Performance: Range: 9/10 Why: 55-60 feet with 2 bands Accuracy: 8/10 Why: Accurate at close quarters, not so much at longer ranges Power: 8/10 Why: puts huge dents in cardboard Reliability: 7/10 Why: Sometimes the bolt catches on the ammo being loaded up in the barrel and causes jams. This is rare and has only happened to me twice. Everything else is fine. Overall: 8/10 Final score: 8.1/10 Nice gun zak!

EDITI will NOT post the gun. Don't ask. However, I will be nice and get more pictures/closeups of the gun tomorrow so you can build off of that.This is my own oodammo pistol. Its not as generic as the others out there, because its the first one to have a slide. The slide can pull back more force that it looks like it can, because of a simple 3 part mechanism in there. It also comes with better ROF, but I haven't done tests as to how fast it can shoot yet.The gun also comes with a new (Well u8mycookies on KI made it first, but I made mine without looking at his. BTW, Darth Gecko Man can go sod off.) removable mag (Well, I have never seen it done before anyways.), it holds 8 shots and can be preloaded and stored in pockets for knex wars. Its pretty powerful, even with one band, I haven't done proper range tests yet, but I think it can shoot 40 feet with one band. I've been shooting this in my parent's bedroom, and it can hit the wall and return 5 feet from my position. 2 times the ammo has returned to my position broken in half.Credit goes to zak for trigger and handle. EDIT- I have had some complaints that the mag isn't mine. I made my mag without looking at the one on KI, I never knew it existed until today, and I DO NOT GO LOOK AT KI SH*T ANYMORE. Now with that taken care of, if you still have a problem, go away and don't come back. Video:
