    Driving a HDD motor

    I'm sorry that I have not reply earlyer but I was busy with my work. I have problems in making the cirquit work. I 'm testing the circuit in bredboard but it does behave like it should be. I hear a sound like the motor is spining but in fact is sticked in one position. If I try to rotate it...

    Driving a HDD motor

    You mean simply that that the motor will not run at full speed or that will not work at all. If its the first case right its ok with me because I don't want full speed. Anyway can you recoment any replacements for the BUZ11?

    Driving a HDD motor

    After a little search I have found this small circuit that the author says it can  drive a Hard Disk Drive Motor. Can anyone verify this please? The site is: http://grant.solarbotics.net/Circuits.htm ant the circuit Thanks

    High Power LED Mood Lamp

    I don't know why but today it worked.... ;D All of a sudden I reprogrammed the pic once more and it worked perfect!!! I even build a second pcb and it worked without any problems! Thank you all! Here is the pcb of the project!!! led.mood.lamp.rar

    High Power LED Mood Lamp

    More dissapointing news ??? Every time I try to program the PIC16F628A I'm using I end up with only the red led to fully work. Blue and Green are working very strange. When I choose the pattern G->GB->B->BR->R->RG-->>G effect there is no light when green and blue should be...

    High Power LED Mood Lamp

    Hello again!!! I've managed to build the pcb and program the pic but there seems to be some problems... None of the green or blue led seems to be saturated (except the red one) and they don't  work as in the project description. There are no random colors and the changing pattern does'nt work. ...

    High Power LED Mood Lamp

    I ordered 2 leds from Ledsee electronics and I m waiting to get them in my hands. I also wait the pic samples from microchip! Until that moment I hope to have the board ready for soldering!!! When I get it to work I will try to make some temperature measurements to see if a heatsink is...

    High Power LED Mood Lamp

    I want the pcb to be as smaller and compact I can so a regulator with a heatsink is a little "heavy" for me ::) But if I don't find a regulated 5V  power supply I will think that option! This is the next version of the pcb ( including the supply bypass capacitor- no air wires required  ;D )...

    I ve only found a 4.5VDC /500mA but I'm not sure I will be able to find one. But I will continue to search in stores here.

    Thanks for the suggestions. I will correct the value of the 3.7 ohm resistor to 3.9 as you comment (I'm not very familiar with the available values of components  ::) ) As for the capacitor, is ok a 0.1uF / 50V ? Also do you think the board has space problems using the  1W resistor? I was going...

    Thanks. The PCB is not finished yet but when is done I'm gonna upload it for other users! :D

    High Power LED Mood Lamp

    Thanks for your answers! I've decided to "go" with audioguru since he claims that his resistor values are the safer and  produce more light that the values described on the project page. Now I have created a pcb for this project but I'm worry about the routes width. I design it with eagle and...

    High Power LED Mood Lamp

    Now I'm really confused ??? Reading all these posts I dont really know what resistor values I must use. audioguru had found  that the project has problems but no-one confirms that. What is the most safe resistor values I can use to this project without burning anything? Thanks!!!
