  1. @chauat Hi there, why don't you just build your design and then share your experience with us. Cheers, Repairman
  2. @Shuhrat I read your post, but your PCB and schematic do not add up. I don't see your 5 MJ11032, D11, C7 etc. in your schematic. Do you have any photos of your actual build? If you have something useful to post and share, please make sure you post everything not just bits of a puzzle. Cheers, Repairman
  3. @mars Hi there, Look at Page 87 and 88 posts from Liquibyte and you will find PCB, schematic and gerber files to make a nice power supply that will work. How would I know you might ask. Glad you asked. I have had PCB's made from those gerber files and built a power supply. And it works well. Look here for my post: "electronics-lab.com/community/index.php?/topic/40835-0-30v-0-3a-latest-data/&page=2" All credit goes to member Liquibyte. Thanks a lot Liquibyte for making all files available. Many thanks also to those who were actively involved in this thread and helped improve the original design. Hope that will answer your question. PS. I f you want to built one like I just mentioned, I still have some PCB's left. I only ask AU$2.50 per PCB plus shipping to your country in an envelope. Cheers, William
  4. Hi Prithul, I believe the answer you are looking for is here: "http://electronics-lab.com/community/index.php?/topic/29563-0-30v-stabilized-power-supply/&page=84" audioguru: Post August 31, 2014 A bit more was mentioned on page 87 Please open a new thread if you want to find out more, as this thread is for completed projects. Thanks
  5. Hello fellow Hobbyist, Take a look at this post: 0-30V Stabilized Power Supply Page 88 posted October 6, 2014 "http://electronics-lab.com/community/index.php?/topic/29563-0-30v-stabilized-power-supply/&page=88" I left out the TIP141, D10 and R15 as per his description. In fact I have had made those PCB Liquibyte designed and built my Power Supply with success. See here: "electronics-lab.com/community/index.php?/topic/40835-0-30v-0-3a-latest-data/&page=2" I have plenty of those PCB left. If you are interested I only ask AUD$2.50 per PCB plus posting cost in a padded envelope to your country. Cheers, William
  6. @Jeremy You may have 2 PCB's for AU$5 plus shipping in an envelope. Two boards weigh about 44grams. Email me if you would like some to: [email protected] Cheere, William PS. Seems your Kit has a problem to start with. Before I found this Forum I ordered two Banggood Kits. It is still not assembled and probably never will be. Anyway, over at this page there is a lengthy description on how to improve the Banggood kit. "www.paulvdiyblogs.net/2015/05/tuning-030v-dc-with-03a-psu-diy-kit.html"
  7. @Jeremy I have built a Power Supply according to Liquibyte post here: "electronics-lab.com/community/index.php?/topic/40835-0-30v-0-3a-latest-data/&page=2#comment-156499" I have had made PCB's from his gerber files he offered. The board has a size of 67x100mm. If you want one or more board leave a message here. Regards, William
  8. Hello fellows, Thanks for for your input in that matter. @HarryA - I have to agree, they are very cheap these days. I did buy a Gophert CPS-3205 last year. @Admin - Thanks for the link. I came across this one also as I happen to have 2 of those DIY Banggood boards. When I started off with Electronics again after some 40 years I felt a bit overwhelmed by Paul's mods. So, after having built one myself just recently, see in Projects Q/A - 0-30V 0-3A Latest Data, I feel more confident. Maybe I give it a go. @HarryA - That 30V 10A offer is a bit miss leading. There are three options to choose. There is a selectable field called Current. If you select that 30V 10A version you will find that is cost US$53.48. Still cheap, but does not ship to Australia. @audioguru - Thanks for you input also. For me it is more about building it than buy if possible. Cheers from Australia
  9. Thanks HarryA, I did look around the forum already. I did actually build one member liquibyte did as he provided gerber files. So I had PCB's made. It is working, was just wondering if there might be anything better out there.
  10. Hi All, Does anyone have schematic, PCB layout of a modern day Power Supply? Regards, William
  11. Hi all, Finally after some months have gone by, my build of the Power Supply is done. I have used liquibyte schematic Rev. 8 and had made the cirquit board according to the Gerber.zip file he posted here: 0-30V Stabilized Power Supply Page 88 posted October 6, 2014 "http://electronics-lab.com/community/index.php?/topic/29563-0-30v-stabilized-power-supply/&page=88" I left out D10 and R15 as per his description. I have plenty of boards leftover if someone has a need for it. There was only one mistake liquibyte made which have outlined in one of the pictures uploaded here. I was fortunate enough to get a big case with a Toroidal transformer from the scrapyard. Also many parts are recycled from various sources. Regards, William
  12. Hello all, A lot of reading here and much more to learn. Also have the Banggood power supply board, still in the bag though - will likely stay there. Have ordered PCB's at Elecrow from Gerber files provided by Liquibyte. So, thank you very much Liquibyte. 10PCB + shipping = US$ 18.50 that is about AUS$ 25.00 Since I have a 24V Toroidal already I will have to settle for a 25V 3A power supply. That is fine for me as it is more important to build it. Thanks to all here. Regards, William
  13. Hi all, I am interested in Guest elboa8 power supply. Is there a PCB available ready to be printed? Thanks for any help. Regards, William
