Suggestions / Re: USB Type-C
« on: June 01, 2016, 05:06:55 PM »
USB-C power is a bit of a kludge. The specs say 100W, but the pins in the connector will wear out if the user hotplugs the power while charging. And I can see most users doing just that: close laptop, pull plug.

USB-C is a bit of a mixed bag, I'm afraid. There is everything on that one connector, even analog audio. Great care needs to be taken in designing power circuits if you want the analog audio to sound good. And since people will also want to charge their laptop over USB-C, that seems like a hell of a job.

I think we will be seeing a lot of budget laptops with features that are not implemented at all, or working not so good over USB-C.

I would like at least 2 standard USB2 ports. Not USB-C, nor USB3.

If you run Linux or BSD and would like to use an external audio interface, your choice is limited to USB Class Compliant devices. None of those work over USB3 or USB-C.

There will also be no new audio interfaces with USB-3 or USB-C as that market is going to Thunderbolt or ethernetAVB. There are a couple of USB-3 interfaces available (most notably from Zoom), but these don't work with Linux or BSD at all.

Why would you want/need that much memory in an audio interface? If it is for storing soundfonts, that's a minority application. It seems hardly fair making everyone pay for a feature only few will use. Or is there an application I'm not seeing?

And please, please, stay away from Creative chipsets. It's about the worse you can get on the market. It gets badly out of sync after minutes. Sound wise, it's fairly OK, but compatibility with anything except Windows is questionable.

Isn't MXM rather expensive and a slowly disappearing standard?

I have to buy some of these cards for repair (iMac 27") and they are getting real hard to get lately. There isn't much choice and they are getting expensive (around 250 € for not even a top of the range card).

More than half of the LCD panels that are being produced today are native DisplayPort. Especially laptop ones in the popular 13" and 15" 16:9 format.

Price wise, that is the way to go. 4:3 will be way more expensive.

An external DP port is less interesting than HDMI because HDMI is far more universal when it comes to external monitors available everywhere. I mean, how many TV's have you seen with a DP port?

DVI or VGA aren't needed. The number of DVI monitors is fairly limited. And while there are boatloads of VGA screens everywhere, implementing it is relatively costly as it needs a DAC. Most chipsets for laptop screens these days seem to have HMDI and DP only. And HDMI to VGA/DVI/whatever adapters are very cheap and easy to get.

Supporting VGA well would also mean a lot of extra work, as some of these screens aren't multisync at all and some have rare resolutions.

Gnu/Linux Distros / Re: FreeBSD

Why do we need to focus on Debian? Is this a choice already made?

I mean, I use and love Debian, but most documentation available on the internet is outdated, confusing or even wrong. And it won't get any better.

FreeBSD has it's handbook, with very, very few errors and all the docs maintained in one central place.

Despite the fact that I love Debian, I have to admit it is fast becoming an unwieldy instrument. And FreeBSD is getting better every day.

Gnu/Linux Distros / FreeBSD

As FreeBSD has had a PPC port like forever that it is actively maintained and has long-term support, I propose FreeBSD as one of the standard OS options.

I think this is the most logic way forward.

Please just include a battery holder for standard 18650 cells. That would make it easy to replace for anyone and every one can choose the cheapest or the highest capacity cells.

Even a Tesla is driven by 18650 cells. Probably a bit more than a laptop, though ;-)

Notebook chassis / Re: Olimex DIY laptop and/or Novena?
« on: May 31, 2016, 03:59:46 AM »
Olimex could be a good choice. However, it's ARM based, not PPC. But since it's open source hardware

AND Olimex has a LOT of experience as a manufacturer of Arduino and other boards, it would be interesting to at least talk to them.

The Magsafe connector has been patented by Apple. And I don't think they'll license it...
