Hi dear friends,
I'm working with an mega169a ultra low power version which is running arduino butterfly. On the datasheet it says, during power save mode the current goes down to 0.8uA.
Anyway, in my code I've shut down everything as much as I can remember, but still it won't go below 210uA. I...
Thanks for the comment. INT0 has the higher priority than INT1. Ok, I think using infinite loop was not a good idea, but can I use a normal variable controlled loop in ISR?
Hi guys,
Facing problems with ISR. I don't know to stop an infinite loop in an interrupt service routine. I have set 2 ext. interrupts. Now int_0 service routine has an infinite loop inside of it that just makes a pulse train.. But I want this while(1) infinite loop to stop whenever the other...
Hello guyz,
I'm gonna interface a ps2 optical mouse with my AVR mega8 MCU. I;ve searched over internet for the protocol details, and I've got some of them which describes mice with 3 buttons(didn't say about the wheel) but I couldn't find any protocol details describing for mice with Scrolling...
Hi Jim, thanks a lot for the circuits. :D nice stuff. Well I just wanted to make a very very simple DC power supply, so I think maybe I should gor for the series connection. Also the secondary has current limitation according to the wire gauge.
well It's nice to have a 10 Amp power supply.
RS..
I heard some guyz to say that, they've destroyed their MCUs supplied from smps. I guess linear is more jitter free than smps. Well, a personal problem. I need to power up two peltier coolers (each rated 12v, 5A, 60W) from a transformer rated at output (12v-0v-12v, 6A). what shold I do...
Sir, can you pls send me one varactor based and one PLL based FM transmitter schematic? I've made two miller based FM transmitters but they suffer a lot frequency drifting.....
Rocket Scientist.
Which software did you use to make the simulation? I used multisim and the result was much worse than yours. :(

what kind of difference?? As far as I know inductive load takes more current from the supply than the resistive ones. Can this somehow drop the supply voltage?
It seems like you need a programmable voltage regulator. Well, if you don't like normal voltage regulators, then you may use a micro controller attached with a transistor working as a programmable voltage regulator with the supply to the IC. You can sense the input voltage and according to it's...
Oops !!! I've made a typing mistake. Actually my mini subwoofer is 3 inches of diameter. Still, as you told, I shouldn't expect a lot of bass, but obviously it would be somewhat greater than that of a 2 inch cone. It's price is 1 USD here in local store. Thought I could get started with it...
Hello guyz,
How are you all? Some days ago I've bought a mini 2 inch subwooofer speaker which has the rating of 12 ohms and 8 watts printed on it.
I wanna make a nice sound system for home use. I'm new to design a class B amplifier. Though I've done some study on class A, B and AB, I'm still...
