    Timer / Power Supply issues for small project.

    Hey Chris, Now worries about the delay - I'm still very thankful for the design. I'm the one who should be sorry for not getting on with it but you know how it is! It looks like I'm not going to be moving house soon and the project will be packed up for the duration - sorry about that, we...

    Timer / Power Supply issues for small project.

    Hi Chris, Fuse added, new schematic drawn, haven't double checked it yet. It might be a while until I can get much done as I start a new job tomorrow, which means I'll be working away during the week, and then there will be a house move. I'm still on it and I'm still very thankful for your help...

    Timer / Power Supply issues for small project.

    Hi Chris, Yep! It didn't - but it was worth a try. I was at least hoping that it would put the component shapes on the board and I could move them around but sadly it just came out with rubbish. Thanks for trying. They say that every cloud has a silver lining and this one was no exception. I...

    Timer / Power Supply issues for small project.

    Hi Chris, Yes - I thought I'd use VeeCAD to electronically work out the PCB layout. Much easier and user friendly than a pad and pen. Actually, there only appear to be about three or four different shapes! That would be great - I can't seem to open the libraries of components without using...

    Timer / Power Supply issues for small project.

    Hi Chris, Thanks for the quick reply. VeeCAD is looking for a file with a *.net suffix, although it does start processing the *.txt file. However, I get the following error message: 'Tango net list error on line 319: Component BAT1_ has a blank pin name.' I don't know if this means anything...

    Timer / Power Supply issues for small project.

    Hi Chris. Well, it's taken me some time to get around to the component ordering (the kitchen didn't quite go according to plan and ordinary life stuff gets in the way of hobby time), but it's done now. I have elected to change a few components (switches, battery holder) for astetic and supply...

    Timer / Power Supply issues for small project.

    Hi Chris, The second copy of the circuit diagram was great. Thanks. I'm a little tied up this week (fitting a kitchen) but I should find time to order the components and make a start on the strip-board layout. The £25 limit at Farnell shouldn't be a problem as I'm going to need some form of...

    Timer / Power Supply issues for small project.

    Hi Chris, Sorry to be a pain but the image of the circuit diagram when downloaded is only 1.2kb. This makes it impossible to read or print. Could you post it again? Thanks, Jack

    Timer / Power Supply issues for small project.

    Hi Barry, Yep - I thought that might be the case. If I had no replies here I was just going to go and get the kit and see what happened. Ditto. This I had thought of as well but, as I can't remember all of my stored power theory - is that likely to discharge the 'bottom' cell to a greater...

    Timer / Power Supply issues for small project.

    Hi Chris, Well! I didn't expect anyone to go to such lengths with answer to my question! Thank you. This type of bespoke curcuit design was just what I was getting to all those years ago - and brain v. electronics atrophy has definitely set in! You're right about finding a V-reg in a DIP...

    Timer / Power Supply issues for small project.

    Hi, It's about twenty years since I last dabbled in a hobby micro electronics project and I'm really rusty + I'm sure technology has moved on a bit since then. I'm hoping someone will be able to give me some advice on the following project. I have this small wooden kit: ...which I wish to...
