Hit the thumbs up icon in the lower right side of my posts.
Like I did in your last post.
No I do not have a circuit board, but I can get one. I know how to solder parts and wires together. Can you please recommend parts for me to order off amazon? Preferably in the USA so I don't have to wait a month for shipping.Do you have a perforated circuit board? Do you know how to solder parts and wires together?
The volume control should have an audio taper and not be a linear potentiometer.
Our sensitivity to sound and light levels is logarithmic so that when the volume or brightness control is turned down to halfway, the intensity appears to be half only when a logarithmic audio taper pot is used. A linear pot turned to halfway produces intensity that appears to be turned down only a little.
In my post #24 I said, "The negative terminal of the battery or power supply connects to ground."
A little 9V battery is too small to light 8 LEDs for long. If the music level is high which is turning on the LEDs brightly most of the time then the current from the battery is 160mA. The 9V battery begins at 9V but when it is drained with 160mA its voltage drops to 7.2V in about 30 minutes when the LEDs will be so dim that you can barely see them. I recommend using six AA alkaline cells which last 4 times longer.
The no-name-brand cheap Chinese LEDs have no detailed spec's. Their viewing angle is probably very narrow.
Take board out of case and bake at 375 deg for 20 min to reflow intermittent solder joints.OTAY, now come here and fix my intermittent cable modem. I gave a Like!
Do you think you could help me get a list together from stuff of amazon, just so I also know I am getting the correct stuff as well?I do not order no-name-brand cheap Chinese junk without any detailed spec's from Amazon or from E-bay.
Instead I order high quality name-brand parts from Digikey and Newark after viewing the detailed datasheets. If I order before 8:00PM it is delivered to me the next morning and they are not even in my country (they are American, I am in Canada).
OK keep us posted on how it is progresing after you get your parts.In personal conversations he is ordering suitable parts from Jameco or RadioShack. If the LED beam is too narrow then he will lightly sand its top for better diffusion.
