    Hi Cryonic, Today the links works fine, must have been a temporary error in some server some ware! I have tried Firefox not that long ago, but it did not live up to my expectations so I removed it. I admit it had some nice features but also it had some drawbacks. Perhaps it works faster and...

    battery charger

    Just a note: The 10 ohm resistor will dissipate 2.5W at 500mA, I don’t know if it’s rated for this in the part list. It’s not rated at the drawing as the potentiometer is. I would use a 5W in this circuit! 8)

    charger for Cordless phone battery.

    The voltage drop across R1 is always 1.2Volts (controlled by the regulator), using (I = U / R )you get the charge current. Example; 1.2 V / 82 Ohm =  0.0146 A that means about 15 mA! If you increase the charge current to 800mA you need a heatsink for the LM317! Got it? ;D

    BT-693 speaker system

    Hi Logan, If it’s still under warranty it might be better not to open it incase there is big trouble inside!  :o But if it’s not, be sure to pull the plug before you try to open it! If you open it look for obvious fried or miss colored parts and try to identify whatever looks suspicious! You...

    charger for Cordless phone battery.

    Hi Guys, Yes 7 volts is too low, that’s why I said “You can power it from any DC-wallwart  9 – 25VDC.”! ;D

    Specialized Power Supply

    Ok, for a laser you need a specified voltage in this case 3V. If you current limit the voltage source below what the laser draws then the voltage will drop too. So you can't have both!  ;)

    charger for Cordless phone battery.

    Hi fever, This is from the LM117/317 datasheet; R1 should be 82 Ohm and you put the pack where it says load! You can power it from any DC-wallwart  9 – 25VDC.  ;)
