Yeah, it's become cheap enough that a hobbiest can order boards in small quantities using the exact same stuff as the big guys. If...
I posted about this a few months ago, but I figure it's time for an update. I've been slowly working on a project to build an open-source...
I'm back at a real computer now, so.... https://www.diodes.com/assets/Datasheets/ZXCT1009.pdf That's the IC that's doing the measurement. It...
0.2 won’t blow anything up. I’m not sure it will just change the reading a by a factor of 2 though. The formulas are in the data sheet for the...
I have a possible reason to not use the motor driver IC. I'm going to cut and paste some thoughts below I posted in another forum. The point...
FWIW, the way I quote prices is in quantity 100 from the Chinese companies I use to get PCB's made. Basically the "what would a small run cost"...
I gave it a whirl. https://github.com/bicknell/DCC-Mobile-Decoder/tree/drv8870-refactor/hardware/reference/Breadboard-1 is a branch using a TI...
I've updated CALCULATIONS and README.
Humm, I have stated that poorly in the README.md file, I need to use better language. The CALCULATIONS.md file has the detailed calculation. Vf...
I attempted a revision of my design that I think might be a bit more clear to new people, but also uses more commonly available components that...
They would absolutely work for the Breadboard version. 4xSOT-23 is a bit large for an N/Z real decoder. FWIW, Mouser does not stock them, and...
The manufacturers I've looked at seem to be using an MSOP 3mm x 3mm form factor part that are a bit hard to find. Not really necessary for the...
Since I've found some people on here who seem to know a thing or two about hardware, I'd like to make a specific request....
Schematic link is on the page at https://github.com/bicknell/DCC-Mobile-Decoder/tree/main/hardware/reference/Breadboard-1, but also in that...

https://github.com/bicknell/DCC-Mobile-Decoder/tree/main/hardware/reference/Manual-1 is how to build the circuit by hand on a bread board, and...
I just committed support for Address, Direct, Register, and Paged programming in Service Mode! I also added a resistor to the hardware design so...
I have been working on and off on a project to build my own decoder -- hardware and software. While it is not complete, it is far enough along I...
Whee! It's been a long time since I posted on this, but I finished the project and made the remotes, and now have them working with JMRI. Check...
iPhone OS 4.1 is out today, including one touch HDR for those with iPhone 4's. I've written a blog post, including a sample photo and will try...
