No proof, It is just my opinion that OSHW projects that are in a single language or use proprietry file formats and so on, restrict access to those who are fluent in the language or can afford the software eg Altium.

Ok, so what if I designed the uSupply in the choice of OSWH champions, Eagle, but it's a bigger board than the free version can open and you have to pay $$$ for the licenses version to modify it. How is that different to say Altium Circuit Studio that costs about the same?

The more accessible the design is to people the better. I'm less interested in the debate about the cost of tools and entirely uninterested in confining things to strictly open source toolchains. I approach the debate about OSHW from the point-of-view that someone WANTS others to reproduce and exploit it. If it looks like they are keeping something secret  then it looks like they don't want it reproduced and hence I start to consider the design closed. The more they want to have people get involved the more likely  the barriers will be lowered. But throwing a design out there in expensive proprietry tool is OK with me.

I think the debate about open-closed is unresolvable by ordinary practical people so looking at it from the POV of the likely intent of the designer will get you a good approximation. If some design info is available to be published but isn't then I'd stick solidly with calling the project closed. If everything is available but unusable to ordinary makers then I'd say who cares it is as good as closed.

It's very simple, I'll do whatever I want, release whatever I want, and use my OSHW logo idea however I want, the end.
Can we please stop the OSHW discussion now.

Monkeh:
How very dare you do what you want with your own work. It's unthinkable.

boffin:
Please please please make the decimal points bigger

(and at least line up the watts under the volts/amps)

About the LCD display. I have questions about the requirements.
I thought to work towards getting concrete numbers from a vendor like gpeg, instead of speculating.

Size? Direct-drive or muxed? Pins on the edge or zebra strips?
5V drive or do we have a charge pump LCD driver.
Transreflective or trans fluid for 100% backlit led use.

Cost hit from using many mcu pins/LCD driver may cause a cheap simple display to cost more in the end.
Added plastic parts needed for diffuser or edge lit. Added mounting plastic bezel if zebra strips verses dip pins. So consider the whole display assembly+driver might be a hassle verses using an off the shelf graphic display with SPI. You'd have to do a bill of materials costing for this to compare.

I like negative contrast and the layout improvements by Whales and others.
