Arduino Music Lock

Had this idea for some time and ill possibly do it when i learn more electronics stuff. But for now, i'll share the idea! So imagine you have a secure locked door. Theres no keypad or keyhole anywhere on or near the door, but there is a microphone setup on it. The only way to open the door would be to play whatever song or series of notes that are programmed into the "lock" with a musical instrument. Since there are several lock-based instructables here that use arduino boards, would it be possible to use one with whatever required components to make a lock that opens with music as a key?

Where to find anyplace with Bamboo in Texas? Answered

I've been trying to find a location in Texas (preferably Central) that either sells or has large stalks of Bamboo. Until I get a place of my own where I can grow my own bamboo, i'll have to stick to finding my own elsewhere. I've looked all over the internet for anyplace that sells it near my town, but like heck they do. Does anyone know where I can get large bamboo stalks anywhere in this tolerable circle of Hell?

Cheap Island Building possibilities

Hello! Ive been doing all kinds of research and planning on making man-made islands for a few years now, and I had a thought on one method inspired by Thinkenstein's Instructable on Trash Rocks. He has been able to make floating rocks using plastic bottles filled with air, nylon fishnet bags, and covering the combination in cement. Tadaa, Floating Rocks. But after seeing his instructable about this, would anyone think it to be possible to make a large floating land mass using plastic bottles of 16oz and above, nylon fishnet bags, and cement? I think it sounds doable, but that's just whats been put on paper.

Small Scale Scuba Gear within $100?

I had an idea for a good instructable. I'm trying to plan out on paper a neat breathing apparatus for a hundred dollars. Constraints are that it has to fit on the face, can be carried anywhere, and should at least provide one minute of oxygen. As a plus, why not add a pump so you can replenish the air supply when its running low. The way i might build this, ultimately, shouldn't be too hard. But what is being difficult is what to use to hold the air supply. would an air tank from an airsoft gun be any good? or would i have to use something different to contain the pressure? Any input would be greatly appreciated! -Jakit

Making a Cryptuino! Cryptex/Arduino Audio Device project

     So recently many of the students around my college campus that get stuck here on the weekends, myself included, find themselves with nothing to do. Personally i want to do something to remedy this. Hence why im thinking of creating a series of challenges and puzzles all around campus on some weekends. How it would work, device and plan, is as follows: -----      Players would pay an entry fee, of which there would be 5 or less in one group. Either way, small number of people to start off with in the beginning. One player would be designated as the "Handler", and would be in possession of the Cryptuino. The Handler would be responsible for entering the first password so instructions on how to beat the challenge would be relayed to the player/s.      If the challenge was beaten, then the group would be given a reward and a new password, which when played would direct the group to a different area for the next challenge. Once they get to the challenge, the process would repeat itself, and it would repeat for a number of times depending on how many challenges there were.      To make things more like a game, the player/s would be able to score points by completing certain requirements in the challenges. Some requirements would be like:  different time ranges for mazes or races, correct/incorrect answers on puzzles, or other things that i have yet to figure out. -----      Im still trying to figure out how to build the device, especially with the hardware part. I also dont have much cash to spare for good shields and parts but i do have a plentiful amount of electronic junk i could use. From what i was told on the Arduino forums, i would need a .wav shield and a keypad to go with my Arduino Uno. Is there any places on the internet anyone would know of on how to make my own shield and keypad?      I have figured out how to make my own SD card slot for part of the .wav shield, and i have a number of button switches i could use for making a keypad. But to make a working shield/board and keypad, i am mostly clueless on the processes. Can anyone give me some advice or pointers in the right direction?

Possible Contest Topic

Is there a contest about the things that can be done with wood pallets? Ever since I saw an instructible showing how to take apart a pallet as well as the amount of wood used to make them, I have wondered if there has ever been a contest to show how useful they can be as potentially free lumber and hardware. After all the uses for pallets that i've looked up on the internet, there are about less than 50 uses for recyclable pallets, keeping these materials from ending up in a bonfire or a landfill. The link below can explain quite a bit about this subject. http://www.greenecoservices.com/31-ways-to-reuse-wood-pallets-make-money/ Maybe a way to lessen the number of pallets that end up being wasted in garbage can be achieved if there was a contest that encouraged the recycling of wood pallets. Anything that can be made from a pallet would be eligible to win whatever prize this contest would have. I personally think this would be a good idea to try. But do any of you think this would be a good contest idea?

How can I make a small TV using a small LCD screen? Answered

I have a movie project idea that requires the use of a prop with one heck of a twist. Im trying to make a "Crystal Ball" that can project a movie from the inside of the ball, and I need to find some way to make it work without the necessary use of any tv or usb cables, even though it can use them. (Ex: in one shot, the actor is holding the ball, and is visible from head to his waist, but there are no cables running from the ball) So it could use video data from an SD card or a USB and also be used as a TV. The largest ball I can find is a 3" diameter clear plastic craft ball from a nearby hobby shop in a neighboring town. I guess what im asking in a nutshell is "how small can you make a diy projector?" Any help with this will be greatly appreciated!

MGS5's iDroid - Can it be Built with Open Source Tech?

I can't get enough of Metal Gear Solid 5! It definitely deserves the 10/10 scores its received! But as cool as it would be to have a giant robot or even a Walker Gear that you and/or your enemies can pilot, I think the coolest thing to have from the game would be the "iDroid". If you havent played "The Phantom Pain" or "Ground Zeroes", the iDroid is a device Snake uses for multiple purposes. Some include: sending radio trasmissions and calling in supply drops or helicopters between the iDroid's location and Mother Base, Displaying a topographical satellite view of the area Snake is in, Organizing Mother Base staff, resources, R&D; projects, and playing music from cassette tapes found while on missions, Just to name a few. (bold font is to differentiate the uses) So is it possible to build a similar device using the open source technology of today? (minus the use of cassette tapes and a 2D holographic projection screen) I'm pretty confident that it can be done, but what do you guys think?

Turning an RPi into a "Sheikah Slate" (LOZ:BotW)

So recently I've been fiddling around with a few things. Plastic recycling, making a bluetooth game controller, and just being blown away by the Legend of Zelda: Breath of the Wild, just to name a few. And after getting a better look at the new key item in the game, the Sheikah Slate, Ive been trying to design one that can do a few of the things the one in the game can do. Im talking about the technical things and not the magical ability things. And just for good measure, throw in portable gaming console for emulated gaming on the go. So far, I have a few components I can piece together, but there are a few other problems that need solving. 1. Can an Amazon Fire 6" Screen be hooked up to a RPi 2 or higher? And if that's possible, is there any additional components needed to pull that off? (im talking about the screen itself, not the whole device) 2. What capacity of LiPo battery would be best suited for a project like this? 3. Would using Adafruit's "Bluetooth EZ Key" module be good to use as a way to control games on the RPi or a PC emulator? Im pretty sure I have more questions, but i'll ask em after these are out of the way.

RPi Zero and GameBoy - Can the New & Old Work Together?

So I recently found out about the Raspberry Pi Zero earlier last week. After looking at the size of the board and comparing it to the size of a GameBoy/Color/Advance/SP cartridge along with the back of a Gameboy Color/SP system, I had an interesting thought. I know that the RPi's have a great use as a video game emulator (with some case or hardware modification to the original gameboy system). I even saw one DIY article that had a GameBoy cartridge hollowed out and a Micro SD card adapter put into it, just so a heavily modded GameBoy Brick with most of its guts replaced with other techbits (mainly an RPi Zero and plenty of wires) could be used to play NES, SNES and GameBoy games while on the go. So since the Zero is slightly larger than a GBA cartridge, would it be possible to make the Zero connect to the hardware of say a GameBoy Color via the cartridge slot on the back of the console? Or what about other RPi's with other GameBoy consoles? I would try to find out about this myself, but i missed out on buying a Zero when they were first announced and i dont want to buy one from a scalper.

Cigar Box Laptop

Around New Year's Day, my family celebrated Christmas (had to wait for some family to visit) and one of my presents was a flat, rectangular cigar box with some gift cards and certificates. I haven't done much with the box, but after comparing it to the size of my laptop, they are roughly the same dimensions! Given that this is a wooden cigar box, would it be possible to turn it into a low-power laptop computer? Since its wood, it would probably be better to put a screen and keyboard setup inside the box instead of the whole shabang (small hard drive, motherboard, etc.) while having the main hardware inside of an external tower. But if it was set up in this fashion, could it still be called a laptop?

Project that needs some "originality confirmation"

I had an idea for a portable workbench/toolbox. when i drew it up it looked like a chest, so i called it a workchest. but when i showed my design to my family, my mom said that this was a design that many women use to carry their makeup and grooming things. i dont really think thats true, but i think some outside opinions might be useful here. so a wooden chest with dimensions at 1 1/2' for length, width, and height with the top unfolding to make a workspace thats 3'x1 1/2', this is something that fashionable women would carry around or keep at their house so they can look beautiful wherever they go? i dont think something like that would ever be intentionally created for makeup.

PS1 LCD Screen into a Raspberry Pi Monitor

So i finally purchased a Model B Raspberry Pi. I'm quite enthralled by the stuff ill be able to do with it, but i figured i would start by making it a case. That idea somehow resulted in using a cigar box i had lying around to turn the whole thing into a laptop-esque build thing. The inside dimensions being 8.5" x 5.4" x 1.5", i looked around and i have a PlayStation 1 with an LCD screen. The console and screen are fine but the hinge is broken. And given the size of the screen, i thought it would be really nifty to disconnect the screen and use it as a monitor. The only problem is im not sure if i could make it HDMI or RCA compatible. Any Tech people think this could be done?

Wii Remote Ports - What can they be used for?

So since the Switch is the main Nintendo console and the Wii sold like wildfire, I recently had a thought for a project involving the plug and sockets for Wii Remotes and the things you can plug into them. Seeing as how Nintendo is all about unique ports for handheld and home consoles, why not remove the ports from a Wii Remote and Nunchuck for use in say (something easy to try) a storage device, like a specialized USB or something? Based on the Wii Remote i took apart, the port is only 6 pins, and you can get both parts of the port with a Wii Motion Plus. I imagine the price for either is lowered quite a bit at used game & movie stores, so what do you guys think could be made with the ports?

Making an amphibious vehicle, but then had a problem...

After watching that one episode of BBC's car show "Top Gear", the one where they do their first attempt at amphibious cars, I had a design idea for one. But after thinking about it for some time, my design brought up some classification questions. 1. In the US, any vehicle with less than 4 wheels is considered to be a motorcycle. If the vehicle I have in mind operates like a car, but has the classification of a motorcycle, AND it can operate as a boat, would it be legally appropriate to label it as an amphibious motorbike or an amphibious car? 2. Taking hydrodynamics, weights and buoyancy into account, the vehicle design so far could hold 2-3 people. If it was two, then the seats would be arranged vertically. If it was 3, then they would be arranged as a triangle. So if it was a three seater, would it be better to have two at the front or at the back? That's all the questions i can think of right now.

Chiptune Guitar Synth Project

So ive recently thought of doing some chiptune music. But when it comes to doing all the programming on a Gameboy with Little Sound DJ, or making some song on Rymtik Retrobits on my 3DS, i feel like i could do better with an actual chiptune instrument. Ive looked in a few nooks and crannies of the interwebs and i have acquired some knowledge of homemade synths, but nothing i dont think i could actually use. I did find a neat link of a guy who made a Guitar Hero PS2 guitar controller thing, and the chord buttons were connected in series. The different chord buttons, when two or more are pressed, create different notes. There was also a whammy bar that made the chipnotes act like guitar notes with reverb. He also added an audio jack to connect it to a speaker or an amp. The one part im trying to figure out is how to make this instrument more of a synth than a one sound chiptune device. It might be possible to replace the "strum bar" thing on the GH controller with some additional buttons that make different kinds of 8-bit sounds while the whammy bar is used by the palm. The sketch ive made should shed some light on what im talking about. With all of that being said, is there anyone out there who could help me design a schematic or something that can help to make this thing better than what i could design by myself? I got the skills to build the instrument, but not the skills to design the electronics and circuits that go with it. Any help is greatly appreciated!

Building A SHTF Computer Using This Pistol Case, Need some Advice

So some time ago, i was at an Academy store and did an impulse purchase. Spent $50 on this durable, watertight pistol case as seen in the accompanied image. For a few weeks, i have just let it sit in my room and thinking about what to do with it. Then i thought "What about a Portable PC?". So i did some measurements, the interior is roughly 12x9x5 inches in Length, Width, and Depth (if you count the lid's interior). At best i have some components, such as a 10 Inch screen from an old netbook, i already have the controller board to make it a regular monitor for a few purposes. But a few things im not clear on is what components would best fit this case? I know its too small for most motherboards, and im not intending to use a Raspberry Pi or a Linux OS. And i also want to do as little drilling or cutting into the case as possible to retain its moisture resistance. If i had to list any criteria for such a build, there would be: Information Storage Connectivity to Larger Screens (aka stationary "tower") Wifi Capability Emergency Power Source Thats just off the top of my head, tbh. In short, im wanting to make a utilitarian computer that could survive (and possibly thrive) in a disaster situation of non-biblical proportions, all crammed into a case that was meant to hold a handgun. Keep in mind i have little to some electronics experience, but i have built a pc before. So who has any advice or what-have-you to point me in the right direction? (i hope this evolves into something pretty dang good. i do believe its kind of a challenge to pull something like this off, going with a case roughly half the size of your standard PC tower)
