      Nice work! Could you perhaps add a surface mount pad to the diode so the same board can accommodate both the through hole and surface mount part?

      Good idea!

        Any comments before I launch the order?

        Are you going to have someone install the parts? Or at least the SMDs?

          I'll do it by myself, I have a hot air soldering station and I've build many smd boards already.

          BTW, @gaweyo, I've just added the smd diode footprint 🙂

            That's a skill I have never tried. I have a hot air soldering station but the project I purchased it for got canceled.

            So there it sets new and unused.

            How much are you going to be selling them for - say 25 units.

              I haven't calculated costs yet, but I my plan is just sharing the costs, just not to loose with each board. Once I have the prototype board working, I'll put a price for the DIY kit (board+components), just the bare PCB, and the complete mounted and tested board. And of course, I can send the gerbers for free too.

              Would kind of kit would you need? Bare, components kit, mounted...?

                As busy as I am I would prefer completely assembled units - ready to install in a printer.

                And you should price them to make some profit.

                  You can try one of those practice kits instead. https://www.aliexpress.com/item/32909277203.html

                  A solder iron, flux paste, and solder are all you need. A cheap Chinese stereoscopic optical microscope makes even easier.

                      @Egon-Net, one option you have is ordering assembled from vendors such as JLCPCB.

                      https://jlcpcb.com/smt-assembly

                      You may need to make design changes to reduce cost and use their standard parts. https://jlcpcb.com/parts

                      https://www.youtube.com/results?search_query=jlcpcb+assembly

                      Just an idea.

                        I don't think we are going to do so many boards to be an advantage. For the time being I will do the boards by myself, but maybe in the future I'm overwhelmed by all the people wanting the boards and I have to look something like that! ☺

                        BTW, I'm already a costumer of JLCPCB 🙂

                          PCB assembly is easier if all the SMD components are on the same side. Then it's easily done using a hotplate, solder paste, and a Mylar solder stencil (available in the UK from Hobbytronics).

                            I know, but for low quantity runs I do it with hot air and without stencil, with very good results. And for this design, size is a constrain. If I were to do a bigger run, I'd rearrange the pcb to be one side only and get it done somewhere lije JLCPCB.

                            Thanks for the advice anyway 🙂

                              It’s getting really nice 👍🏻
                              I’m pumped to get my hands on one!

                                Please everyone wanting some pcb's PM me with:

                                • Number of PCB's required
                                • Bare PCB/DIY kit/assembled
                                • Where to send in the world

                                I want to do a small batch first (10 or so), but since I don't know how many boards you all may need, maybe a bit bigger batch could be enough. Once I have this numbers, I'll put a price for every option.

                                Thanks in advance to everyone!

                                    You asked for a PM but I don't know what that is.

                                    I do want some as I previously mentioned.

                                    If the price is right I would want 25.

                                        First batch ordered!

                                        15 PCB are on its way 🙂

                                        If there is no problem with the design, I'll order about 50 more, wich would be enough for all the boards everyone asked for.

                                        Anyone wants to betatest a board from this first batch once arrives?
