In my website I have an article on this ... **broken link removed**
Check the "Etching with Ferric Chloride" section
I used Sodium Carbonate ...
Its normal its an exothermic reaction so it will produce heat...
Good Luck

Not needed but doing so can increase the reaction...
I have no idea if that can be done with Proteus ,but their are software which can be used to do this kind of job..
One of them is http://www.zelscope.com/
The interface which can be used is given on their site... or here http://xoscope.sourceforge.net/hardware/hardware.html
But their is a big...
The "result" variable is of type unsigned long value ,as per your equation ,it will loose the floating point value i.e.. truncate at decimal point.Are you sure ,this is what you want to do?
Hi,
I am going to buy a laptop ,is Dell Inspiron any good ...
Two models are quite good for my needs Dell Inspiron 14R and Dell Inspiron 15R
what you guys think about it?
The two models differ in screen size and graphic cards ,the screen size doesn't matters much for me but the graphic card...
Does it POST(Power On Self Test),i.e.. can you see anything displayed on your screen,if not then you can use a POST card to debug the problem .If you don't have a POST card or don't know how to use it ,you can disconnect all the devices like RAM ,HDD, CD ROM etc from your motherboard ,then by...
Sorry for the late responce

Thanks for doing it for me but I need a solution for...
Hi all I got a problem with printing a schematic, its in a PDF file and its too large. I have an inkjet printer so its not possible to print that large schematic, so I want to print it part by part on an A4 size paper and then I will join it. Now I want to know how you people do this kind of...

Download the STMicroelectronics datasheet of LM317 ,in their you will find a circuit for 12V battery charger or else you can search in google for 13.5 VDC power supply circuit.Anyway if you use LM317 voltage regulator,remember its a linear regulator if the difference between the input voltage...
For charging Seal Lead Acid Batteries
Their are two options 1) Fast charging method will take 5 - 6 hours and needs complicated circuit because of the charging method. 2) Float charging method will take upto 16 hours and most commonly used ,for float type charging apply 2.25 V to each cell i.e...
DC motor will do it,the faster you rotate it the more output power it generates.A small DC motor will not generate too much power but will generate enough power to light up a LED.
You can also use a bicycle dynamo in place of a DC motor,a bicycle dynamo will generate much more power than a...
