I have just bought a laser nebular disco thingy off ebay (incorporating a red and green laser) - and whilst its works fine, I don't like the fact that it switches between various modes automatically (flashing, steady, red only, green only etc). I opened it up to get some pictures of the circuit board - and wondered if anyone with knowledge of electronics could point me in the right direction with regards to bypassing the multi function controller on the circuit board. I just want both lasers to remain on all the time. Thanks

There was a good idea in another topic to use your OrangeBoard as a note-pad for on-going projects. That reminded me: My orangeboard is very slow. It's not a bug, it's size (1100+ comments). Is there any way of speeding it up? Apart from going through all 1100 comments, deleting them one at a time, that is...

Hi. A basic question; I need to connect a breakout board to a strip board. What is the best method? PCB Latch plug header? I have tried putting a wire through the strip board, through the breakout board and then soldering into place, but I do not get good connectivity. Any help is much appreciated.

Hi everyone, I have been thinking of starting up a website with a variety of breakout boards available. What I'm talking about is basically small PCBs with pins, where you just solder a chip on, and have all the pinouts available to connect things to. You know, regular breakout boards. Variety of chip footprints (tiny ones, big ones, through holes, surface mount). You could buy pin headers as well, or just buy the plane board. Would you personally see use in something like that? Since it would be breakout boards, shipping would be cheap (they're just flat and could go in an envelope). How much would you (if you were to use this type of service) would be willing to pay per board? Thanks a lot, Catsunami :3

Has anyone recently found a roll of corkboard suitable for building a bulletin board? I was unable to find any corkboard at Home Depot, and the bulletin boards available at office supply stores are too small and too expensive. This Instructable suggests a carpet supply store might have the right stuff:https://www.instructables.com/id/CorkBoard--Bulliten-Board-How-to-make/Do you know of any other sources?

A Velleman sound-to-light kit (Radio Shack MK103) is a small circuit board powered by a 9v battery which lights LED bulbs when an audio signal is received by the microphone. I would like to connect this board directly to the headphone (output) jack of my audio device (metal detector), thereby bypassing the microphone input. This would allow visual operation of the detector without the use of headphones. When an object is detected it would illuminate an LED as opposed to sending an audio signal. Is it possible to de-solder the microphone on the circuit board and solder in a 3.5mm male connector which would plug directly into the audio output device? I have never worked on a circuit board before and I have ZERO knowledge of electronics, but the kit is only $8 - so I think it's worth a try - if the electronic wizardry is correct, that is. Thanks in advance for any help! -Bruce

I need to put items back onto this circuit board that came off. Just want to know what they are. In the picture below, they are shown with the arrow. One is a cylinder with "671 220 50z" written on it. The other is just a tiny rectangle with a solder connection on each end. My unit won't connect with satellites and I'm wondering if these that somehow came disconnected have something to do with it.

Does anyone know how to construct this balancing piece of wood that holds a bottle of wine. I hate to spend over $20 for a 50 cent piece of wood that I could make at home.I appreciate your help, and I just know there are a few of folks that are mechanically inclined that can solve this...Thank you!http://store.komando.com/p-244-wooden-bottle-balances.aspx?utm_source=l&utm;_medium=email&utm;_content=bottle_balances&utm;_campaign=topBalancing ActCoolest way to store a bottle of wineIs this magic? No, it's a little science. The weight of the bottle shifts the center of gravity that makes the wine appear to be suspended in mid-air.You'll get loads of comments, smiles and laughs! These positive reactions make these wine bottle balances a perfect gift! After all, Ben Franklin said, "Wine is constant proof that God loves us and wants us to be happy."Made of solid wood.

I want to build a LED writing board. It's basically a markerboard with a LED light behind it and it takes advantage of special fluorescent markers. My question is, how can I achieve that the board doesn't light up unless the marker is applied to the board. You can see in the video, that the glass stays black/dark until you write on it... How does that work? http://www.youtube.com/watch?v=pQwdWvGIq5A

Any idea on how I can make a track to attach to a wall to have a cork board that is able to be slid up and down over a dry erase board. It would need to "lock" in order to keep it in place when slid up but then easily able to be unlocked to slide down when access to it is needed. I imagine the tracks would be something like the ones that slide drawers on Ikea desks etc... sort of like this but perhaps vertically. http://www.whiteboardsetc.com/Horizontal_Sliders.htm Horizontal ideas would help as well as a second option Thoughts?

Hi, i need some help. A few weeks ago i took apart a RC (remote controlled) car circuit board but some of the cables couldn't hold and just broke off so i'd be so thankful if one of you smart people out there could tell me (or draw on the picture) where everything is supposed to go (including the antenna :-) and the forwart and backward motor. thanks Kacper

After reading a lot of sites (and a few instructables *cough*westfw*cough*:) on microcontrollers, I want to finally buy one. the only thing though is I also need a development board and im stuck. Theres so many, I can't even begin to know which I should get.I was looking into the Z80 since I could buy a development board for 40$, which is pretty high for me (50 is around my max), and it also has a usb programmer, my laptop doesn't have a serial connection, but Im not so sure anymore. I know *some* c++ and I'm willing to learn c so I don't need a basic module or anything.Do you guys know of any good ones for me?

Hello everybody, this is a new idea of mine that I want to share with you. the snap board concept. It is made of zip lock bags, card board, and duck tape. This idea could be used in notebooks or you could just make a wall of this and make all different bags and holders that snap on to the zip lock rail. You can slide the bags from side to side if you want. I might put this in a notebook case so that I can customize it with pencil holders and other organizers. Or I might make it so that I can snap on different covers and stuff like that . Please tell me any other ideas to use this idea and comments. I will post an Instructables when I make a true model and get feedback. Please comment and subscribe

Hello all, I'm here to offer my LED board kit. You may be familiar with it if you saw my Ready, Set, Go! Lights Instructable. They were originally a product I was making to light up Hyundai Tiburon's but that ultimately did not pan out and now I have quite a few spare parts.I will be selling these at cost in an attempt to make back a portion of the money I spent designing them. (AKA need money for new projects! :P )You get everything you see in the picture:(1) blank LED board PCB(10) Super-flux 'really bright' LEDs (1 extra)(6) 1/4W surface mount resistors (3 extra, they are notoriously small and easy to lose)(1) 1N4001 diode for reverse polarity protectionAvailable colors are white, blue, and red (custom combos are available)Price is $3USD per kit, shipping to North America is $2.50USD (Canada Post Light Packet) up to 6 kits.$1USD soldering fee for those not comfortable soldering.Paypal is the preferred payment method.Check out some pics of finished boards: http://www.rumblerobotics.com/tiblights

Does anyone have any ideas how I could make something that resembles a skateboard or mountainboard truck at home? I want to build my own motorised mountainboard from various parts on the very cheap, of which none will actually be from a board. The trucks seem like the one thing I might have to buy since I can't think of a way to add turning and carving capability to a homemade board. Any ideas would be most appreciated.

Hi, I am building my own "homemade Virtual Reality Simulator" that would consist in a moving platform on top of another, both connected through simple compression springs. I am a big guy and weight almost 100 kgs (200 pounds) therefore the platform should be designed to these standards. It shall look similar to the image attached. QUESTION: Do you know a good information source to find the right materials (even suppliers) for manufacturing the upper and lower boards? Thank you for any feedback.

What happens when you bring several guitarists and 147 stompboxes together?Well, you set a record, raise money for charity and probably create sonic chaos. Here's the flickr set.From the Tonefreq blog (despite the press release date, this record was set July 16, 09):Nashville, Tennessee - 6/10/09 Nashville radio personality Aljon Go throws a party to break last year's record of the world's largest pedal board and raise money for the National Kidney Foundation of Middle Tennessee.

Hi, my project consists of a vibration sensor that, when enabled, will trigger a motor which will function for a certain amount of time, then stop, and stay in this position as long as the sensor is detecting vibrations. When the vibrations stop, I need the motor to reverse polarity and function in the opposite direction,for the same amount of time as before then stop, and repeat... I'm a first year electrical engineer so please consider me a rookie in this field. If someone could provide me with a suitable electrical circuit, with names and values for the part, i think i might be able to draw the corresponding board. Thanks

Hey guys! I searched for something like this, but got no hits. I have an old snowboard in the basement that isn't even worth selling. I'd love to do something with it, but I'm not too crafty. Can anyone direct me to, or create, an instructable on how to make a shelf out of a snowboard? I think it would be tacky in a pretty cool way. Thanks a lot.

Hey guys, this looks like the right place to ask, my buddy wants me to find him this board game he's played before and it's called Weed WarsThe desription of the game is there, but no where I have found will tell me where I can buy the game! Does anyone know where I can buy this game up in Canada? Or will I have to buy it online, I figure that would be possible if I could even find the company that makes the friggin game.Thanks anyone if someone knows what game I'm talking about!

Greetings! i bought a 42" LCD digital signage unit on Ebay (ViewSonic -ND4210w) but alas, i made a rookie mistake! It functions as intended, but needs a constant web feed from an RJ-45 cable (its ONLY input!) sigh......... So! im looking for advice on the possibility of buying the equivalent 42" input board tv or d-sub (anything but RJ-45!!!) and replacing the EVIL RJ-45 video board.... or something............HELP?! Much Grovelling and worship in advance!

Hey, I was walking past my little sister watching PBS Kids and on one of the shows this girl was trying to make her own shoes. Out of cardboard. Lightbulb. The only reason that they didn't work is because they got waterlogged. I am thinking that with good enough sealing and strong enough glue, useable shoes made from cardboard are a possibility!The only problem is that I don't have foamboard or time to spare or a working camera at the moment. If anyone could carry this idea further than me, have at it!
