I also have a spare dvd player, a dvd drive(doesnt work but spare parts might come in handy) and an old razr phone that the screen doesnt work but the rest is fine...Any projects i can do? or anything i can make that would come in handy? I would appreciate it greatly for some tips or project ideas..thanks..

upcoming project

I just got an ipod touch for christmas, and I'm going to be making an accessory for it that's like a laptop, and I'll call it an iTop or something like that. Anyways It's a tiny bit bigger than the ipod touch, the ipod touch will fold up and be the screen, here what the features of the bottom part will be (The ipod plugs in via the dock connector. High quality audio output Video output mini usb for easy syncing a speaker with an amp and a lion battery to power it a little lion charger a switch to wheather you want output audio or from the speaker I/O ports* *There will be a picmicro in it, and I'm going to make it so that if you output different frequencies (maybe some programmer could helpme) the pic will do different things. I posted on make a while ago how cool it would be to have an open source ipod, and this is the closest you can get. There might be anywhere from 4 to 20 I/O ports, and it'll be controlled by the ipod. Can any of you think of anything else to add before I buy stuff?

USBeDuino Project

Hi, I just want to inform you about a new project, which bring a tiny microcontroller board for your home automatication, to you. It is called "USBeDuino". What is USBeDuino? basically it is a microcontroller board with 3 shields, which, when combined make a very great platform for home automatication. Features: Processor: Attiny85 2 x 3A PWM Output sink channel 3 x Analog input channel 1 onboard poti 2 onboard Buttons Input Voltage 5-24V Small size The idea behind the board: Sometimes you need only projects with very less pins, such as light controlling or pump controll (in the garden). Then you dont want to use a full arduino, with a power or a relay shield... then you can use the USbeDuino! https://www.indiegogo.com/projects/usbeduino-project-all-or-nothing#home Please tell me, what do you think about this project? Does it have potential?

Lens for a project

Hi! Im gonna try out this project, Telescope , as I know nothing about optic or lens function maybe someone could just let me know if I should go for a Tele-Auto 6.3/400 mm or a Sigma 70-300 mm F4-5,6 DL Macro Super. I asked the creator but as time runs out for me I hope this gives a faster response =) Thanks

Router Project?

On one of my recent bike rides I came across an old (I assume from size) network router. Now being a collector of anything electronic I stored it in my back pack for future use...However as I began to think, I realized I had no idea what to do with the thing.  Here is the most basic infromation on the router: - Made by SMC - Called: BARRICADE SMC7004VWBR - Wireless network router, with a standard four ports on the back - Made in Taiwan (just thought that might be important) So does anyone have any idea on what I can do with this router? I already have a wireless router at home so that use it already filled.  And yes, it is fully functional.

LED project

Here is what I got going; I want to use a 9v battery to power a led for a project on one of my guitars. I'm not sure what kind of resistor I would need. On hand I have a 33ohm and 1m resistors. The led is a 5mm cylinder with an inward cone on top. The led ranges from red, blue, yellow, and green in different patterns. It came from a light up snow flake and the original power source are 3 LR44 button batteries. I'm not sure what rating the led is, since I didn't see anything on the packaging. The schematic is just the same as the original setup minus the 9v(LR44s) and the switch(little slider). Thanks in advance for the help!

Project Help

Hey everyone I was hoping someone could help me with a project that I'm working on. I'm relatively inexperienced with electronics so this might just be a simple solution, but here it goes. I have a 4.8V, .9A power source and I would like to connect the power source, a toggle switch, a LED, and a USB port in series. A pretty simple idea. I don't know too much about LEDs, but I do know that you have to use a resistor with it. And I've heard that the LED and resistor have to have a voltage drop equal to the voltage of the power source. My main question is this though: how can I use the LED along with the USB port? Will there be enough voltage left for the USB after the LED is lit? Thanks for any advice!

Project impossible?

Using an Arduino UNO, an MP3 shield(and 2 speakers) and a breadboard, can I have 10 white LED's, a potentiometer to control brightness, a potentiometer to control flashing of the LED's, a stepper motor or a servo, 2 buttons for the motor(left right), and finally 3 buttons(play, stop, skip) for the mp3 plus a volume knob. Is this possible, or will I need more that one Arduino? Speakers: Input interface: 3.5mm Stereo Jack Input sensitivity: 650mV ± 50mV Degree of distortion: ≤ 5% Speaker impedance: 4ohm Frequency range: 85Hz ~ 20kHz SNR ≥ 80 dB Output power: 3W * 2 Rated voltage: DC 5V /1000mA

Question by heindup 


A proposed projects for physics...

Hello there techies, the project USB charger was proposed by me to our professor in physics II. unfortunately he didn't accept such project HOWEVER he was happy. He just said that our project is not yet satisfying. He wants us to do a power inverter. We will buy a 2 6-volts battery and series it and it will output a 200+volts with a 30watts and then we will insert any charger such as a nokia cell phone charger and then voila, it should be charging. Do you think it is possible to do? And another project I proposed is that we will make a REAL TIME CLOCK using a 7 segment. I already had a schematic from youtube. and it uses a decade counter ICs but unfortunately I think such ICs are not available in our country, can you help us sir? T____T

Arduino as a programming project?

I decided to make something with Arduino as a school programming project, because it would be nice to learn something more complex than playing with LED arrays. The question is WHAT? It has to be a PROGRAMMING project, not an electronics one and therefore must be interesting and hard to do. Everything I can think of is a lot of electronics with some 50 lines of code at the end... Any ideas?

Need help for a project?

So I've to make a multi-functional garbage container, which would be solar powered, and it must have an arduino . The idea is that the container will have 2 LCD displays showing a moving eye, a sensor for when something is thrown inside (the sensor must activate an audio device, which should say "thank you" at the moment) another sensor fr when the container is full (it'll have to make an LED blink) . So my knowledge about arduino is fair (about coding) and I wold need help for that and also for what components to use (mainly what sensor as I described) All those things are gonna be made for a project and our budget is about 150$ Thanks in advance!

Video projection on glass?

Hi I was doing some resources on how to achieve a rear projection on transparent surfaces like glass, but without of much success (there are projects on this site, but all are using a black projection material). I would like to do it on a shop window using a projector. I have found out that I need some special foil to get this working, but most of them are black and not transparen and there are a lots of brands. I am wondering if there would be a DIY solution, maybe a frosted white sticker cut to the size would work, to still keep a level of transparency on of the window. Suggestions are welcomed! Thanks!

However, my mechanical and electronic skills are lacking (yet not absent). Does anyone have an idea of what the physical end of the project should be (what should be controlled)? At first I was thinking about doing a remote controlled car, but that is not original enough. I am looking for ideas of things anyone that goes to the site can control, so something that would be OK to give control of to the public.
