cheers for all the replies, i was thinking about a few of them there. I quite like the simplicity and cheapness of your idea,audio. But i think i will try Jays or eblc's idea as it will give me alot more flexability with the power supply voltages (i think i will be connecting the wattmeter up to...
Hey,
Im currently trying to come up with a simple circuit that will interface a pulse output of a wattmeter to a chip. The levels of the output of the wattmeter are 24 volts for the high part of the pulse, 7 volts for the low. I wish to convert this to 3.3 volts for either the high or low...
Cheers for the replies!
Sorry for the lack of details, but the TEG can generate 0.21 watt at a load of 100ohms and a temp difference of 27 degrees C. (57 hot side, 30 cold side).
Ye are right, unfortunately this wasn’t as much power as I was expecting. But its just an idea im trying to play...
Im hoping to string together a self powered fan for a processor (just an project, not very practical, i know). I am hoping to do this by placing a TEG module between the heatsink and processor. Unfortunately, under tests, this doesnt generate much more than 0.8 volts or so.
So, im hoping...
Im after getting my hands on a color cctv camera module with audio, and a wireless transmitter and reciever. When i went to try it out, the picture stays color for about 2 seconds, and then changes to B&W. To see if it was the transmitters fault, i dis and re-connected the camera to the...
i have a suitable heatsink, well, it worked well for my dry cell circuit anyway (salvaged from a nikko remote control car). I thought that it was the out put, and i replaced the 4ohm speaker with a 8ohm speaker. But the same happened. I dont see why it could be a circuit fault, as it worked for...
when i was younger, i had made a portable amp using the tda2003 in a bridge config.It was powered by 12v of D dry cell batteries. Since i am as poor as a curch mouse, i got fed up by the cost of replacing the dry cells, that i connected up a 12v lead-acid 6.0ah bat. One of the chips then...
i have also seen that playstation adapter for sale, bout 11 euro. (~11$)
I was wondering, can this adapter also be used to convert the video signal to rf for a tv? i have tried the videorecorder method, but this cuts the rf signal after 5min. I set up a 555 timer circuit to "rewaken" the...
Hello there, i have an ickle problem, and was wondering if somebody could help:
we are after recieving a new cable decoder box in our kitchen. The previous model had a RF output that i used with 75ohm cable to send the picture to our sitting room @roughly 30m with no problem. Unfortunately...
