Hi Audioguru, got to say I can relate with you. Ive had a bit of fun with free flight when I first started aircraft modelling. More than once I have seen one fly away, with the timer to make it come down/back failing.....Doh!! I have not been flying rc for quite a few years, but Ive decided to get back into it, and fancied building some of my own kit this time round rather than buying it. Im still going through the links that were posted earlier for the glow driver. Im almost set on the one I want to make now though. I have a question about Ni cad chargers as well...I see there are a few charger circuits in the projects page on this site, but has anyone found or designed a 'charging station'?? that is a unit that allows you to charge different types of batteries (NiCad, NiMh, etc) all from the same unit. A friend of mine is looking for an all in one intelligent or programmable unit, that could be made rather than bought....anyone out there done it, looked at it or working on it? A challenge maybe. Way over my head. If anyone knows of a link please post it. Thanks Ian

Hi Hotwaterwizard...... All I can say right now is 'WOW' You must have searched out every glow project on the entire internet. Im very impressed and greatfull. Thank you. Only problem is...now I have to work out what to build. I have quite a bit of reading to do. I didnt realise there were so many ways of doing the same thing, or is this the point with studying electronics? That you can take an idea and modify it to almost anything you want to.... I cant wait to learn enough to start designing things myself. Right now though...back to the reading. Many thanks Ian

Hi Jingi, Now that souds like a really good idea. Ive seen it mentioned in the threads, so If I understand it correctly, it would allow a super fine tuning of the output voltage. Would this second pot be 10% of the original value? and is it easy to wire the two pots together? Thanks for the answers by the way. Ian

Hi all, forget my last statement about the adjustment. Found it in the diagram. Serves me right for reading the post at 2am....lol.

Hi Hotwaterwizard, thanks for the two links. I had the first but the other is new to me. Im going to have to do some homework now to work through the circuit diagram. The second links circuit does not seem to have any shown output adjustment? (I think...) so does the circuit regulate the output ot the plug automatically or is the adjustment just not shown on the diagram. Ive yet to try to translate the page, as the english link was not working last night. Lots to learn yet...all good fun though. Ian

Thanks Ginji, I was a little lost to be honest with all of the suggestions that had been made in the two forum topics. Youve saved me a bit of head scratching with the components youve listed. I will now start to get some parts together and hopefully I will have a working PSU in the not to distant future. Ian

Thanks Ante, I will have a look at the downloads page as you suggested. Its a nice change to find a forum with so many people willing to help. Ian

Hi, this is the first topic I have started so have patience with me. I a beginner within electronics, and sadly have ideas bigger than my understanding at the moment, but Im here to learn. I fly radio control model aircraft, and Ive been looking for a better version of the glow plug driver that is fitted in my field box. Ive come across a circuit diagram on the web, and wish to convert the diagram to a PCB. Here lies the problem. How do I convert the diagram into a working track layout? Is there software available that can do this or can anyone give me some tips on doing this by hand. Also can any of the experts here have a look at the diagram and let me know their suggestions on improving this if it needs it. I have seen much simpler diagrams but ive been told this is one of the better ones, and Im looking for the excuse (lol....) to build something while waiting for the discussion on the 0-30v PSU to give me some uprated parts suggestions Thanks all Ian - bigpetespc

Hello all, I have been following this discussion with interest as I wish to build this power supply as my first 'home brew' PSU project. I have a transformer rated at around the suggested 'upgrade' level, but I dont want to start collecting other parts until I am sure there is nothing else to change. I would like to make mine the 'upgraded' version with a 5A output, so I need to get to the bottom of the changed components list. Im a beginner to electronics, so if anyone has a finalised upgrade list I would love to have a copy. Im not too worried about keeping the costs down on this one as I want this to be the only bench supply I build for a while, so it has to be good. Does anyone have the suggested component list yet? Hope you can help and thanks for a really good forum. Ian (bigpetespc)

Hi, thanks for the info. I re read the posts, and was thinking along those lines myself this afternoon. I think it was just a nostalgic thought on my part wanting to see the old 'moving needle'...lol. Im going to start hunting for parts to make this up, and I will have a go at the digital meter as well. Ive made simple things in the past, but this is a bit of a challange for me. Hope no one thinks Im being a pain with the Newbee questions. Ian

Hello all, I hope someone can help. Im new to electronics, but want to build this power supply as a first project. I have studied the circuit and Im beggining to understand bits of it, but I want to build the PSU with a fitted moving coil volt and ammeter. Please can someone point me in the right direction as to where and how to connect these items to the power supply PCB? I know this subject hes been looked at by a few people in this thread, but I need a few clear instructions....Im a newbee. Thanks Ian
