                Thanks everybody for the interest. I order parts for 10 units. Will allocate them according to the order in this thread (one per person unless they will be spares).

                If there will be more demand, I can do one or two small runs later. This is the first time I order PCBs with SMD service so prefer to keep it small.

                The out of pocket expense for the parts (including shipping, taxes, etc) is indeed ~$30 and the pie chart shows the breakdown. As you see the 3.5" display with capacitive touch dominates the cost and prices went up recently due to the global shortage.

                All parts were ordered from China, including the Pico which is currently hard to find at its nominal $4 price (Digikey has only 2 left, Amazon sell for $8 and up).

                  @zapta If your out-of-pocket costs are $30 I'd like to send you $60 plus shipping for the unit.

                  Thank you again for designing, documenting and publishing the design of this unit.

                    Thanks @alankilian, I really appreciate it.

                    This falls into my hobby part of my life so my time if free and I enjoy it, not to mention giving back for all the help I have got here.

                    😉

                    BTW, here is the Kidcad render of the PCB. The non populated components are not needed and were added to assist with the software development. The most difficult to solder are the two 0.5mm pitch flex cable connectors. I did solder them on the prototype but it was a pain (they bridge easily), so in this batch they will be soldered by the PCB vendor (JLCPCB), together with other components they stock. They don't have the Pico and the current sensor so I will solder them (easy) and so are the two connectors which need to be assembled in a certain way so they don't get shorted by the LCD on the other side.

                        It sounds like the first run might be sold out, but I am interested too.

                        What other features does it provide, besides the steps/s shown?

                            JLCPCB rejected the PCB order since one of the footprints was incorrect. I fixed it and increased the order to 20 PCBs. This run will still be of only 10 units (only 10 LCDs and Picos on order) but it will be easier to make the next 10.

                            This is the first order with this PCB layout so I don't want to commit to too many before validating it.

                                @zapta great work, well done. I’m waiting for @T3P3Tony to put my one of the old version together! I think we’re still waiting for the screen. A more commonly-available one would be good; maybe a PanelDue with different firmware?!

                                    I think the first batch is already gone, but if you go for a second batch, I would like to order one analyser.

                                    Thanks!

                                      If everything will go as expected (JLCPCB assembling most of the components), it shouldn't be too difficult for me to assembled them and I should be able to make larger batches. Let's see how the first batch of 10 will go and if they will work well.

                                      BTW, it's a bank holiday here today so I updated and released all the files https://github.com/zapta/simple_stepper_motor_analyzer . The enclosure was designed on Onshape and it makes it very easy to share an interactive 3D model with export capabilities. https://cad.onshape.com/documents/58d3fc7e6c256c4f6a684caf/v/194a8feb7fe55d4b68b92318/e/96371cb25b019416be0a198b

                                        @zapta could it be used to tune spreadcycle parameters?
