The cost is pretty much equivalent. It is easier to build and fits in more lights. The performance is equivalent.
Finges: there was already a specific zener mod FET driver. You could also easily modify the earlier revisions as well (but not the v1.0 versions without some modification).
I don’t do Windows. I was looking at cheap Windows laptops to program drivers and wondering what are the minimum requirements to program these and other boards. If you guys could suggest what is needed that would be a big help, thanks.
It wouldn’t take much at all, a $50 (used) netbook could probably manage it. They are very simple programs. Most of the tutorials are for windows, but a few people here do it in linux as well. That could be a cheaper option.
I don’t do Windows either. You can flash stuff from Linux if you like, and I have instructions available for setting it up in Ubuntu. You should be able to run it on pretty much any computer with USB, though on older ones you may need a lightweight version like Xubuntu.
Then, to build and flash most attiny13a-based firmware from inside my repo, it’s just “cd person/project ; …/…/bin/build.sh foo ; …/…/bin/flash.sh foo.hex”.
And, of course, use whatever you like to edit the sources and manage files.
Afterward, you should be able to use everything in my firmware repo, including the build and flash scripts, with no need to muck with Windows or AVRStudio. This stuff is all designed to run on unix systems, so it’s basically native on Linux and OSX but it’s a little awkward on Windows.
I have a problem with the Offtime memory. The driver change the mode with first clic even though I cut off the power for a few minutes.
I changed already OTC capacitor, just to be sure it is right value.
Other features seem to be working correctly.
I am using layoyt v0.24 and flashed with star offtime v1.2.
has anyone been able to use any version of wight’s boards with a zener mod as was intended with the design layout? or has everyone had to stack c1 and the zener diode together? does only RMM/MTN’s board work with a zener layout as intended?
I measured both the capacitors capacitances and they were OK. I installed capacitors back and I got OFFTIME memory to work. I may have originally installed the capacitors the wrong way?
In any case, the driver works, so thanks to all!
