How can I modify a drinks chiller running at 10c-18c to run at temperatures of 0c-5c?

Help. I want to convert the baumatic bw18 drinks chiller into a refrigerator. The cooler runs between 10c-18c. I need to alter it to run at 0c - 5c. Is this possible? What parts can I modify? Do I purchase or modify the thermistor? I think it is more involved than resetting an appliance timer. I need to convert this model specifically.

Convert AAA battery power to 12V jack?

So I figured out a really good option for my external rumble pack I want to make, I see these Wii lightguns use X2 AAA batteries and have a micro switch that engages the internal rumble motor on the handle of the gun. The batteries are connected to a microswitch and the switch is pressed after the trigger is physically pulled. How can I convert the AAA batteries power method into an external 12V power connector for continuous use and stronger motor vibrations etc? Like I said this is my first DIY thing. I want the AAA battery method to be converted to a stronger more capable 12V. I plan on buying some strong force feedback motors that need 12V. Eventually adding a small Solenoid too.

How to Power an AC device using DC- from an outlet

I have a heating pad (Sunbeam, the kind of pad used for muscle aches etc.) that plugs into the wall (110v AC). It says on the pad that it draws 42watts. For various reasons, I'd like to have the heat generated by a DC source rather than AC.I'm thinking maybe there is a way for me to plug some kind of converter into the wall (AC to DC) and then plug the heating pad into this which will still result in heat. I have no idea if this is possible. The pad has a switch for three different heat settings.Can I do this? How?Thanks for any suggestions!

How to power an old laptop screen with an old laptop battery ?

Hello instructors, I'm currently playing with Rasberry pis, and I just started a new project. I found information showing how to re-use the screen of a dead laptop via a controler board you can find on eBay. I'm planning to integrate all this in a suitcase to create a mobile retro gaming console. It should be easy to add a simple 220V plug to power all this. But I was just thinking it could also be nice to be able to use this on battery as I also have many laptop batteries @home. Rasberry power input is about 5V 3A Audio amp input is from 1.8V to 12V Screen controller board is 12V 4A Here is what I want to do : > When plugged : Add a circuit to charge the battery via a 220V input. That circuit should also convert the 220V to the power needed for the Pi, the audio amp  and the screen. > Unplugged : Add a circuit to convert the battery output to the power needed for the Pi, the audio amp and the screen. I have no idea where and what to search for. Should I reuse the laptop power unit ? Any help would be highly appreciated. Please excuse my English mistakes. This is not my mother tongue. Thx. B²

add a mini pcie slot in place of expresscard?

Ok, so if we've looked at the pinouts of the expresscard 34/54 slot and the mini pcie slot, we know that: -they both use USB 2.0 -they both use PCIe -they both run on similar voltages so i tried my luck and wired up a mini pcie slot in place of the expresscard slot in my laptop. ive got all the pins wired correctly and all the grounds are grounded, but my wireless adapter card is not recognized. first off, skip all of the "why bother adding a wireless card when you've already got one?" and "this is just a stupid idea" remarks, thats not what im asking. the miniPCI wireless card ive currently got works, but the bandwidth is really limited because its an older technology than mini PCIe. but back to the question at hand. why isnt my mini PCIe card recognized? i have a feeling that it might be the "CP USB" pin on the expresscard slot, which, on the pinout sheet is labeled as "card inserted", but i have no clue what i do with that pin to tell the computer to check for a card. does anyone have any ideas? expresscard pinout: http://www.interfacebus.com/Design_Connector_ExpressCard_Bus.html mini PCIe pinout: http://pinoutsguide.com/Slots/mini_pcie_pinout.shtml any help would be greatly appreciated.

How to convert 13.4V AC power to 12V DC power?

Hi there, Can anyone give me some tutorial on how to convert AC power to DC Power? Basically I have a transformer step down the AC voltage from 230V to 13.4V on 50Hz. In order for me to be able connect LED light directly to the wall, first of all I need to convert the AC Power to DC Power. To be honest I am a noob when come to electronic part especially the calculation section so please go easy on me.  What I have done so far is getting a rectifier and transistor. I tested the rectifier at first, it convert AC to DC power successfully but somehow my voltage drop by 1.7 Volt. I end up getting 11.7V. I notice that the voltage goes up and down from 11.73V - 11.79V. Then I add a transistor with 16V and 100UF to smooth the wave. When I checked my voltage goes up to 18.32V - 18.37V. Due to lack of knowledge, apparently I got myself a wrong transistor. After googling for a while I found the formula but cant figure out how to use them. After asking around apparently I need more than just rectifier and transistor to keep the LED last longer plus the AC Power with 50hz will make the LED flickering. I need help in building a complete 13.4V AC power to 12V converter plus a power constant current source.  Thanks in advance.
