    Woo-Woo Power saving speculation

    ok so I didn't read the whole thing cause quite frankly he just rambles. but this comment kind of got to me. lets talk about education, particularly debating. the idea behind debating or any good conversation is both being concise and on topic. the topic of conversation here has gone from...

    Are these designs realistic for my setup?

    ok for starters how big do you want it? second how far do you want to transmit? what sort of data or transmission is it? looking at Arduino or the beginners micro will teach you a hell of a lot real quick. now just remember the first computer was the size of a warehouse and is now...

    Where can we get Peltier tiles?

    if you need peltier ebay has thousands too, they are just heatpumps as stated, and I have found some great uses. if you want to know their cost click on the myriad of links that have been supplied or goto ebay and type in peltier. not that bad a price and they can be used for a lot of things...

    help for installing hspice

    http://www.synopsys.com/Licensing/Installation/Documents/install072/hspice_install.pdf hope this helps somewhat. we deal more with electronics and coding than IT stuff unless we get a good look at where you went we won't know where to look. there are common things though, try to search for...

    Help Googling circuit names!

    your relays being directly controlled by a micro is not the best idea. but anyway if you need more pins on your microcontroller try a "shift register" it uses roughly 3 pins to make 8. hope that helps with running out of pins.

    TEAR DOWN - Diode really needed for solar charger?

    I have no hands on with solar yet, but my research into is getting extensive. the diode seems to be so when the battery is charged it does not discharge onto the panels. the diode specs I leave to others on the forum but I hope I have helped in some way

    Help Needed: 12V SLA Battery to Charge a Phone

    if you are truly worried about weight then I would steer away from SLA battery. the smallest I have seen is about 7.2Amp hours, and its a half decent weight. about 2kg try http://www.ebay.com/itm/NEW-Dynamo-Hand-Crank-USB-Cell-Phone-Emergency-Charger-/300593826063 this has the added bonus of...

    3d printer

    ok since my last post we have been waiting on parts. the worst part is most people give links to digikey which works great if you live in America but in other countries they charge too much for delivery, 4 ptc fuses weighing less than an ounce and each about the size of a stamp cost $45...

    New Programming Language Anyone?

    I find programming to be a headache I know this is only because when I get stuck and try to find the solution my head starts hurting as it gets people trying to explain the physics behind a computer when all I want to do is be able to find the right way to type the line If (I=1) then.... lol...

    newbie looking for advice

    the thing to think about as you go is always "why?" why did those diodes blow? then think "how?" how to not blow them next time. and try to remember what the component is designed for. so a diode is a 1way device. the why usually gets figured out from the what but sometimes you have to go...

    3d printer

    oh wait. I just thought of something for that fan. the barrel itself is ABS plastic and the nozzle is brass with a heating element on it. the idea is to get the nozzle hot enough to melt the feeder ABS plastic so I am guessing the fan is there to stop the heat melting the rest of the body, in...

    newbie looking for advice

    dramazo just a quick addition. If you do seek advice when fixing these items make sure to have a good camera close by. pics are usually good to see what we need to. also try to describe the fault as simply as possible. Don't go of on a tangent just tell us little things like "light comes on but...

    newbie looking for advice

    the parts you are getting are not going to be good for tinkering. the motors in those drives have next to no torque, the lasers aren't visible by the human eye and the components are well beyond a novice(I still use through hole myself). to find something to tinker with the best thing is find...

    3d printer

    so that's why you need heat... why would I need to cool it? I see it on a few designs but it doesn't make sense to me

    3d printer

    why do I need a cooler? abs plastic warps when its cooled too quickly. in fact a lot of designs have a heat bed that it gets printed on so there is less warping

    https://lockitron.com/preorder there are thousands of these around the net. you already have cctv so hook up one to the front door as well. there is an app called ISpy which I like too. it goes on a computer and then streams across the net, currently I have seen it used for motion sensor and...
