there are a couple of issues

ubuntu is fussy about isp's - they sometimes don't work straight away, some faffing with adding yourself to a dialout group is needed, dmesg-ing i think, unplugging and replugging, the system will find the isp ok but steadfastly refuse to talk to it

and it sometimes only recognises usb if you run avrdude as root and explicitly specify usb, even though thats the default i think

avrdude 6 doesn't like the open source firmware on the olimex, it's a reverse engineered clone of something, not written by olimex - but a one line change can fix it

edit - all that said, i did get it working fairly easily , by following an adafruit tutorial and googling the problem (compiling avrdude 5.11 aside, but i got some help with that ) , i've got no idea if you can edit and save the state of a vagrant vm - but should just be a matter of following the tutorial to get it working
Adding yourself to the dialout group is to be expected if you're not logging in on to a graphical console session. (Same would go for disk group if you want access to a disk or DVD, video group if you want access to the framebuffer etc etc.)

dmesg output should give you the tty that the programmer has been assigned, assuming udev recognises that it needs a tty. It might be you need a rule to force that.

yes I think that's it ,you have to add a number to a file

i think the fuses went back to zeros because of my impatience and i may have reset them with that but cant be sure. If you have any ideas i will, try but if not i will grab another chip and replace it. The joy of the flashing lights on one has made my day, so i am reinvigorated.

apart from those 3 i think theres another fuse which controls whether a chip can be flashed or not - if thats been flipped it'll be unflashable

I'm not sure of how to place heatsink parts on my Module Tester pcb.

Does anyone could explain it or have a picture of it please?

adam · Post by **adam** » Sun Oct 18, 2015 12:17 pm

the flat part of the heatsink goes flat against the pcb - i had to bend the fins on the heatsink i think to make it fit the case, there were also 2 silver tabs sticking out of the end that i needed to remove, probably best to do this before soldering

i assembled everything first, bent the legs on the regulator 90 degrees & bolted it to the pcb before soldering

Thanks Adam!!

Does the bottom face of the tester have to be placed like that please??

adam · Post by **adam** » Tue Oct 20, 2015 2:08 pm

thats the top - that isn't a noodle toaster

lcf · Post by **lcf** » Tue Oct 20, 2015 2:30 pm

Well that's the bottom, certainly inversed...

Sorry I understand...

someone else is getting some edges pcbs made - i'll let you know if he has one spare

adam · Post by **adam** » Tue Oct 20, 2015 2:32 pm

you need to turn the case round - the standoff in the middle goes under the screen

lcf · Post by **lcf** » Tue Oct 20, 2015 2:56 pm

Yes he contacted me for Edges pcb, thanks to have mentioned me.

So the other standoff falls under the big heatsink?

Looks like it

Do you mean an M9 thread? No I don't think so.

The 9mm pots that I sell have an M7 thread (as pretty much 9mm pot out there have) and they fit fine.

some fresh clouds and braids just arrived. top quality, electrically tested boards with a confirmed 100% working layout, from a european factory that takes care of it's workers and the environment.

£15 each as usual

I'll take a Braids PWB - I presume these work with the Grayscale front panels?

adam · Post by **adam** » Sat Oct 31, 2015 4:02 pm

Thanks, yes lots of people have used grayscale panels already
