One stormy night at HackPittsburgh, Marty McGuire and Matt Mets made this short video about the new Make: Electronics Components Pack 1.
It has everything you need to do the first 11 experiments in the O’Reilly Make: Electronics book.

(same as question above.) that i can use to cool a polyimide ink and maintain it’s temperature in just 25 degree celcuis
Yes. It is called a Peltier It is a device that cools by running an electric current across two different metals.
Hi if you know any website or anything (free e books)where i can learn how to check the transistor ,resistor,diode or any electronic component by analogue multimeter (for biggners) then please let me know.Also is there any website where i can learn from start that how to repair a basic radio.
Thanks
Start here – check out their other videos
Note: I did not watch them to see if they are good or not, but just did an internet search and found them
There are many solenoid motors that can be found on the Internet and most are intricate mechanical devices built by machinists. If your not a qualified machinist and would like to build a solenoid motor then this video is for you. The solenoid motor is built from a VCR video head, 12VDC solenoid, LM311 comparator, TIP120 transistor, white LED, CDS cell, IN4001 diode and a few resistors.This is very easy to build and cost less then 10 dollars.
Just remember there is nothing you can’t do so just do it.

I have a Haier brand tv, an RCA surround sound, and Toshiba DVD. I can’t get all to work at the same time w/o unplugging one and plugging in the other….
go to a different web site!!!! Neil knows nothing and proved it!
several out there that i looked at explain everything you asked even with diagrams. try this one:

The answer you got here was a cop-out.
i can tell anyone who asks any question to go "Look It Up"
that sucks!

I am looking for an online store in SA that do shipping within the country, other than Rabtron, as they do not have a lot of goods.
try Digikey they ship everywhere

I’d like to be able to generate significant voltages of DC for experimentation purposes, but so far am having difficulty in creating/sustaining such high voltages. My hope is that the answer may lie in building a voltage multiplier, but I know very little about such technology. It seems I could potentially build one if I knew what components to get and how to configure them. Any help would be appreciated.
yes, you can use ordinary diodes and caps for this.
The difficulty is in adequate separation and insulation between stages.
For example, if you start with 120 volts ac, from a simple isolation transformer, you can get 160 volts per stage. You need 400 volt diodes, although I’d get 800 volt ones for extra margin, such as 1N4008, as the price difference is small. For the caps, it depends on the current. I’d get perhaps 20µF caps. You need only 200 volts, but I’d try for 400 volts for extra margin, in case one stage dies.
reference has more details.
edit: I’d be sure to use lots of fuses, like 1 amp ones.
And I’d get some high voltage resistors, so you could build a voltage divider to measure voltages.
For example, a 100:1 divider could be a 99 M ohm and 1 M ohm. The 99 M could be 4 – 22 M and 1 – 11M. You may have to adjust the 1 M upwards to compensate for your voltmeter resistance.
A thousand to 1 would be a 1 Gohm resistor and a 1 M resistor. You can get the Gohm from places like Victoreen, or build it up from smaller resistors.
Note that 1/4 watt resistors usually have a max voltage rating of 450 volts.
I have seen web pages that go into detail on how to do this, re epoxy and other techniques to maintain the high voltage.
