    Peltier cell beer cooler

    ok so having experimented with peltier I have found a few things out. now first is the voltage, while they are extremely current hungry at their peak (mine were 12volters) I found having the voltage also lowered the amps drain. off course it took longer to cool things but I still iced a few...

    Android tablet s Oscilloscope

    I wasn't thinking of making the the MIC line for sending the readings through, use it as a data line. use a secondary micro controller to receive all the data from the probes then convert it to a data line that the tablet reads over the mic input and translates into a grid. sampling rate would...

    Laser dalek!!

    ok so the laser doesn't burn..... burn what? A simple laser pointer is enough to temporarily blind someone with possible permanent disability. being a Whovian I love the idea. Davros would be proud that even a miniature version of his creation could at least blind someone. having said that I...

    Power for Multiple DC Motors

    have you got a diagram showing how these are hooked up? are they series or parallel? are you using a Hbridge or just a transistor? do you want to control the speed of each motor individually? where are you measuring the power from? measuring at the wrong point could give weird reading have you...

    Android tablet s Oscilloscope

    ok so we all agree USB is not the answer. how about using the audio jack? it has a microphone input, could you not simply code over that? the problem I have is that a good tablet will set you back $400. I really don't want to plug something into it that may fry it. Bluetooth or wifi is a great...

    Android tablet s Oscilloscope

    there is probably a reason for that. think of it this way when I get my laptop, I plug in the USB, plug in power and run the oscilloscope for hours on end. on a tablet if I plug in my oscilloscope I won't have power... so Bluetooth is the best option. My thinking is you find one for like a...

    Old folks in-home personal alarm system?

    ok my 2 cents worth, simply get a personal alarm http://www.geekalerts.com/personal-alarm/this doesn't have any wireless thingy on it, but at 120db you can hear it over a long distance. it comes with a nice neck strap and makes both finding the person and knowing they are in trouble so much...

    USB Chargers

    car USB charger is a start. as it only peaks at 12volt (13.8 is usuualy a car battery but will say 12volt to make it easier) this is actually a good start there are hand crank USB chargers that only generate 5 volt, make sure however the voltage is regulated... oh and its exercise..... solar...

    USB Chargers

    when it comes to anything that plugs into mains power I would highly recommend buying the well built items from well known suppliers. that lady died for a couple dollars. I recently bought an Ipod charger for my GF when she plugged it in the metal case kept shocking her. that was a lesson I MUST...

    wifi based communication systems for corporate offices using wifi diect

    I use Viber if that helps, it uses wifi for calls and sms if you get really bored I think you will find the devices are out there its just what you need so software side. Ios has facetime and works on ipod touch so no sim needed. if you want a program that does not use the web but is for inter...

    Arduino question

    steve how would I get the most buttons without using the analog pins? every schematic I see wants to use the analog pins to read a resistor to calculate a value thus representing a button. I am hoping to figure out how to use just the digital pins and get about 30 buttons, which I can press 2 at...
