  1. 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
  2. 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.
  3. i have open one of the charger i found no ic in it but just a small transformer and 1 or 2 transistor. and other components. thats it. i donot know how much ripple is there in the ouput of charger as i don't own cro.
  4. 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.
  5. my ckt required only 200mA at 5.1V and transformer rating says 9Vac 500mA
  6. 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.
  7. 8) It is better if u include the size and the language in which the magazine is it would be better
  8. 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
  9. how can i buy such modules can you send me some pics or similart things so i can get a idea i am also going to open one charger of my mobile phone so i can get more ideas
  10. 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..........
  11. this RF reciever was in car alarm, how unreliable can be this reciever, i have got a 433Mhz module which is PLL and crystal controlled actually i want to ask how reliable this reciever can be...
  12. if you are totally unknown then u can also go for http://en.wikipedia.org/wiki/Switching_power_supply
  13. Guru Can you provide me some guidance for designing such a supply even some good links can help me...........Smallest possibe............ zak4000 can know what are these from http://en.wikipedia.org/wiki/Switching_power_supply
  14. i have little idea that this can be done by two methods 1> Tansformerless design 2> Switching power supply design now i want to have very small transformer or no transformer at all
  15. 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
