I am wiring this up, and I would like to limit the current being drawn from 18v DC/DC converter.

What would be the simplest way of doing this?

We have to change the lights in my tabletennis club. We are going to put up around 50 panels in 3 strings Each panel is 40w and 24vdc. I was wondering what the best and most cost-effective way to do this might be.

One of the things I was looking to do was to get a single driver for several panels. Maybe a 200w driver for 5 panels? But would it then be better to do it in series with 120v or in parallel. And should the driver be constant power, or?

I will appreciate any and all help!

I have several tapes (yes actual cassette tapes) of my grandfather reading a novel.

Unfortunately a few of the tapes have degraded to the point that I cannot play them back.

I would love to recreate his voice, to "rerecord" the missing bits.

The recordings are in Danish.

Is this possible?

If it is, how can I go about it?

Where can one buy a food supplement with Rhamnose?

I have a Mission MS 200 Subwoofer where the power supply has stopped working. I was quite happy with it, and would like to try to fix it, also I don't have the money for another. I have taken it apart and have narrowed the fault down to the PSU. I have visually inspected the solderings and components, and nothing obvious is wrong. I am not good enough to be able to reverse engineer the board, and was hoping there might be someone here with access to a schematic? Failing that, any pointers on where to maybe do some in-circuit measurements to narrow down which part(s) might be broken, would be very highly appreciated!
