from what i understand, you mean placing a diode like so (as included in the attachment) regarding the question of the usage of a rectifier with a U.motor, its because the necessity to reduce the motor power output.

hi there, I'm currently facing a problem with the silicon rectifier, http://www.alldatasheet.com/datasheet-pdf/pdf/35499/RECTRON/6A8.html with the current setup which is at the attachment. The source is a AC current of 230V 50Hz , while the cap is at 0.3μF. The setup is to provide...

its funny, if i reduce the first resistor which is R1 to a smaller value it works. which is from 3Mohm to around 50kohm, is it possible that both of the resistor must not differentiate too much ? or is there a limit for the timer?edit: i might found my error, seems like there resistor can only...

i've tested that using a LED, and it keeps on lighting forever =( the timer should be 40sec on , 4 sec off. but not sure why. might have fried my 555timer when i hook it up to a 17VDC power source. i'll get a new chip and try it again. as for the transistor, I've actually took this from a...

actually I'm building a circuit as so, it uses a 555 timer to control the relay. i've done the simulation and it works out fine but when applying it in a real circuit board. the result are not the same as simulated. can anyone give me any advice regarding this?

considering this relay http://my.element14.com/durakool/dm84-2012-35-5024/power-relay-dpdt-2co-24vac-8a-pc/dp/1557207" what does contact DC voltage meant? and to energize / activate the coil i need a 24v current to do the job?
