17mm & 20/26/27mm single-sided DD/FET driver release: A17DD-SO8 / A20DD-SO8 / etc

it is zener ready

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.

Any Windows laptop from the past ten years will do everything you need to program these drivers.

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.

I wonder if it would work in WINE in Linux?

AVRStudio might work in WINE, but why would you want to?

true

Because you don’t need it :wink:

would probably work on a Raspberry Pi…just take a while to compile

My buddy compiled some software for his ham radio for a relay…said it took over 6 hours!!!

Thank God for screen :slight_smile:

P.S. I like using checkinstall instead of make install…it creates a binary for later installation

I Recently was unable to get a v44 with Zener to work. RMM saved my day with the suggestion to place the input cap directly on the Zener pads.

Wight. If you find the time it would be great to have another layout with additional 0805 pads by the Zener. Right where the v44 silkscreen is now?

Checkinstall is nice if you need to build unpackaged stuff from upstream… but in this case, it’s much easier to just install the existing packages:

sudo apt-get install gcc-avr avr-libc binutils-avr avrdude avrdude-doc

Those are all the necessary tools.

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.

Thanks guys. I don’t know Linux but I used to know windows. Probably go with the evil I know.

Oh, do you normally use a Mac? If so, this might help:

Or maybe this:

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.

Can it be used 1mf 16v instead of 25v cause i have like zounds lying arround in the office?

Yes

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.

seepeli, can you take a pic and show us your driver? Makes it a bit easier to figure out what’s going on…

I’ll take a picture when I get home.

Sounds more like a bad/dead capacitor, Do you have a DMM with capacitance option , measure the capacitance individually.

If not, remove both capacitors, put fresh ones, preferably from a different batch.

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?
