winding 230 volt pulse transformer
well actually yes.. i took it out of an old 3000W voltage stabilizer.. or at least thats whats written on its case.... only 400W?? no wonder why its all blown up lolz.. when i took it out all its windings are burnt black.. :( please give me details as to how...
transformer secondary sheet winding
I am trying to rewind an old transformer (EI type) taken from a 3000W voltage stabilizer.. i will use it in dc-ac inverter 12VDC to 220-240VAC (50Hz).. Please tell me all the specifications i.e. no. of turns in primary and secondary, the dimensions of the...
I am a newbie in electronics.. I have been trying to build a 4 bit remote control for different applications in toy cars etc.. i used MC145026/27 encoder/decoder pair to generate the signals n all.. they work perfect when connected directly with each other.. but im having problems in making...
Re: wireless control
had anyone tried this circuit?? i've built it but it doesn't work.. on the RX side the LED is always on! while on the TX side LED only goes on when the signal is given.. i've checked all the connections and everything.. still no use! is there any problem in the circuit or...
radio control with mc145026
the led in the receiver circuit connected with 7th pin of IC through a resister.. is it supposed to light when the signal is received? or it will remain on? cuz when i made the circuit it doesn't go off! while the LED in transmitter goes on only when signal is sent.. :(
circuits with mc145026
thanks it worked! but i need a simple and longer range AM transmitter and receiver like around 100metres.. can you give me a circuit diagram? or any url? i searched it on the net but couldn't find a good one!
fm transmiter mc145026
using ASK will eliminate the need for modulation?? do u mean to say if i use AM transmitter/receiver i can directly connect the MC145026/27 ICs with them? and they will work? if not then how can i make them work even with the AM trans./receivers ?? like which component(s)...
mc145026+led
thats a very complicated stuff! can't get it at all! i'll describe the whole situation again..
see i have made a signal generator circuit with MC145026.. and i also have simple FM transmitter ciruit which can transmit the voice.. on the other side.. i have MC145027 circuit which...
mc145026 diagrama
But i want to build one of my own! i dont have a credit card to order one on the internet.. and its not available here in the market! so building one of my own would be the easiest way! if you have the design then plz let me know! do i have to use the ASK modulator/demodulator...
mc145026/27.
i even tried with the AM transmitter type.. it still doesn't work.. do u have any circuit design of an AM transmitter and receiver which can be used with those ICs?? or is there any other way out??
mc145026
hello!
i want to make a 4-bit radio control. i searched the circuit design and i got the one in which TWS/RWS RF modules are used.. can you tell me how can i make the circuit without using the modules?? i've made FM tramitter and receiver circuits.. which generates the signals but at...
