Hi Guys. To the people that have their psu built. Where did you get your parts from?
Prasimix: with the group buy planed. Is that for a complete kit?
I think that will be impossible. Too many parts for making a kit. Maybe with THT but not SMT parts. At least that is beyond my current apprehension of electronic kit. When I think about group buy that is primarily for specific parts like PCBs, enclosure, TFT display, maybe some ICs like W5500, etc.
I really try to keep up to date BOM that can be found here. Yes, I know that choice of suppliers is not optimal. I found e.g. just recently that Farnell don't want to sell to private persons (only to companies). TME cover most of the world but I don't know what is shipping cost outside Europe where is bargain.
If anyone wants to compile e.g. Digikey/Mouser/Arrow or anyone else I can assist if some doubt arise and we can merge that BOM with existing one and make it available on the GitHub to everyone.
Hi Guys. As I plan to build one PSU for myself also, I did a "little" price comparison to find the best prices for needed components. I added 2 more suppliers to the BoM, Digi-Key and RS Components, with relevant component part numbers. I also added some parameters to the components descriptions, corrected few mistakes in BoM and suggested few other things to Prasimix. Now I have sent the revised BoM to Prasimix for checking and I hope that he will release it soon on Github.
Now in short: I added the best prices I found for every component of each supplier and found that the total cost of components listed in BoM for individual buy is currently around 255 € (without VAT and shipping costs). The calculation does not include PCB's, TFT Display, Arduino, Meanwell PSU's, AC Input Option components and Custom Enclosure. In calculation I took into account that many components have MOQ (Minimum Order Quantity) and if you are buying components for one PSU, you have to buy some extra components. Of course Digikey and Mouser are selling all components in one piece also, but sometimes is cheaper to buy 10 pcs of the same component from another supplier.
And, as I promised (in post 411), I did also the calculation for Group Buy. So, if we are buying components for 10 sets, the price will be much "better", currently around 195 € (without VAT and shipping costs). Now, IF we go forward with the Group Buy, someone has to buy the components, repack whole this mess and send the packages to the participants. For repacking we need also a bunch (ca 1000 pcs) of ESD bags, what also cost money. I have calculated that I can handle all that mess and the final cost for one set will be
210 € (this covers all shipping costs from suppliers to me and cost of ESD bags). Shipping cost from me to you I will check later. And for people in EU country, VAT will be added also.
But first we need to get together 10 people at least to go forward. So, please let me know how many of you are interested in Group Buy.
I'm doing this because I'm personally also interested to get the components with better price. So, 9 more people please. Who's in?
If you have any questions, please don't hesitate to ask.
Cheers,
Mihkel
