I live in ahmedabad which is in gujarat state Now can u tell me is there any dealer for maru in my city or near me -
heat sink for transfomer
nikhil arora replied to nikhil arora's topic in Electronic Projects Design/Ideas
yes another transformer heat is only 5-10% of the heat of the the first one but the faulty transformer was still working and giving good voltage even it is short it is possbile. -
heat sink for transfomer

i think this is the problem so how to check the transfomer quality in my city the quality is poor most of the times is there any method to check transformer quality I tested my ckt without load and even without regulator ckt only transformer was kept on and i observed that 70-80% percentange of heating was due to transformer itself. -
heat sink for transfomer
nikhil arora replied to nikhil arora's topic in Electronic Projects Design/Ideas
my ckt required only 200mA at 5.1V and transformer rating says 9Vac 500mA -
how to reduce transformer heating how to take away heat from the transfomer as we use heatsing for transistors is this possible with transformer My ckt needs 5.1V@200mA i have used 9Vac transformer 500mA rating on its box i cann't say how much it can deliver. Now i am drawing only 200mA even though it is heating.

8) It is better if u include the size and the language in which the magazine is it would be better

may be these can work: www.elektrotekno.com www.AvaxHome.ru www.elektor-electronics.co.uk www.elektor.de http://www.elektor-electronics.co.uk http://www.elektor.de or this ebook password cracker software can work ;) eBook-RAR-Cracker-v3.rar

i have done that in very good manner using TSOP1738 as reciever and a IR led driven by NE555 as transmitter. now to send signals you just have to connect the reset pin of NE555 to Tx of 89c51 and that it and write a simple test program. now TSOP1738 is costlier then simple ir-photodiode but 1738 has many features like noise immunity, IR light intensity variation won't affect your link only decreases or increases the range...... Now we know we cannot achieve this we IR-photodiode so i have looking for nice ckt to work with using photodiode..... which is not just amplifier or comparator..........

SMPS(Switch Mode Power Supply)
nikhil arora replied to sizan007's topic in Electronic Projects Design/Ideas
if you are totally unknown then u can also go for http://en.wikipedia.org/wiki/Switching_power_supply -
i have started a google group and I invite you there this group is for games, especially for those who have slow PC like PIII or PII or celeron or similar and low end graphics card or use onboard graphics cards which comes with motherboard http://groups.google.co.in/group/game4slowpc post here few links and start some discussion

interface relay to 8051 uc
nikhil arora replied to mohammed_senior's topic in Electronic Projects Design/Ideas
how much curret ur 12v device uses if it is using less current (<500mA) then u can use ULN2003 to control that device it is very easy to use with controller. if it is less then 1A then u can connect two or three ouput of uln2003 for more current. Solid state switch are better than relay for lesser current. -
can any one suggest me equivalent of these these are not avliable in my city. Si9410DY MTD20N03HDL ZTX694B thanks in advance

I have a battery backup system with 6V SLA(lead acid) battery, But few ckts work on 12V which are used rarely. but they are important. so how do i get it. I know I need step-up DC-DC converter I will be glad to know the chips and links to their datasheets. I have gone through h**p://www.electronics-lab.com/projects/power/030/ but i need more
