    I am not receiving topic notification.

    Is anyone having this problem? I have experienced problems before, with mail taking a couple of days to come through at times, probably due to problems with my Internet provider but I don't think this is the problem, I am receiving all my other usual e-mail.

    How two use this transformer for PSU.

    I'm not sure how I can use this transformer it has, 10.5V(9.5A) 0V 10.5V(9.5A), what output V and A can I get?. 12VDC would be ideal, with 9.5A or more would be good, I have made some sparks trying to work it out, so I thought I'd better ask the experts before I do some damage. I want to use...

    components swap

    Hi all, Maybe there could be a section devoted to components swap. I'm sure there's plenty of members of Electronic Lab that have recycled all kinds of electronic components. I have all sorts of bits and pieces some of which I have more than I need, and some things I have are very useful that...

    Datasheet request

    They were flogging these off cheap at Dick Smith ;D. So if Dick Smith decided they were outdated, they must be ancient. As always, I search long and hard for this datasheet and no go. Philips (OM1681C) signal IC car alarm subsystem. Thank you :).

    Playing with hydrogen

    I am looking for methods of producing hydrogen from water. If anyone knows of any good sites please let me know. And also does anyone know of the best material to use for the electrodes that doesn't deteriorate. I have done some experiments with sulphuric acid dial looted with water and water...
