If you sold the PCB and published the BOM, for me that would work. Between Digikey and other suppliers, the components would be grouped individually, which would allow me to sort and install in order so I didn't get lost."
This would probably work for me as well John. I have a Hakko station with a fine tip head and .020 solder. Plus a magnifier light fixture, can't recall its power though. Would I need anything other than this do you think? It's the steadiness of the hands that is likely to be the big issue I think, lol.
For me it would be like your lighting and YLB kits of just "plug and play". Catering to the 10's that may have a soldering station and soldering skills is foolish.
Maybe so, but to get these assembled it would require me investing several thousand dollars minimum with no guarantee of recouping my investment. I can't really afford to take that gamble. It's simply not cost effective to get something like this built unless you commit to at least 100 units or more. I'd much rather go the fully assembled route if it were possible. I just don't see the demand for something specialized like this MB as for stuff like lighting and battery replacements.
If you were to get enough preorders for a factory build run of 100, what would the unit price be?
I'd guess in the $40-45 ballpark, I haven't checked on assembly of this particular design. I just go on what other projects with a similar parts count have cost. It might be more if I get snagged again with the Trump tariffs, last couple of builds I paid 25% more than expected!
I want 5 boards for sure with a bom and diagram so I make sure have the components properly placed. Like Rod my only doubt is my hands shaking but this looks intriguing to build. Maybe one every few weeks.
If enough interest is there I would be in for 1-2 boards assembled.
I would vastly prefer to do an assembled version, but I'd need to get commitments for at least half of the run in order to shoot the dice and order 100 boards. I know I'll be using some as time goes by, I can see using this and the ERR Cruise Commander M for some really nice feature laden diesel upgrades. Rule-17 lighting, cab light control, functional ditch lights, etc.
I envision using them in several older Weaver SD-40's and pre-TMCC Lionel diesels, just as Ron plans. So I would commit to minimum of 6 assembled boards, and likely 5 more after I get the first batch installed. These should also work well with your sound board, right John? I would need to get you to Fedex them, if possible, just to avoid the whole cross-border mail thing.
I would also take perhaps 5 bare boards for minimalist installations, without all the functionality.
I think what we need is to start a list of folks that will commit to a specific quantity of the full up boards and see if we reach critical mass. I think I might take a deposit on those like I did with the TMCC buffers to cover some of the costs. If we get enough commitments, I'll go for an overseas build.
In looking at the overall picture, I don't see this making it to enough firm orders to do an assembly run. That being the case, I'm going to simply offer the blank boards I have for $3/ea.
I have posted all the current build data in the first post of this thread. The schematic, BOM, and assembly drawing all reflect the current board. The Gerber files are also there if you want to make your own boards.
