Earlier quoted context omitted.

"Designers" trying to show off and that dont understand anything about basic usability. To the "designers" : Next time do a simple web page without stupid scrolling hacks,for god sake.I'm sick of it ,really. Dont mess up with basic usability just because it looks good on your Macintosh.I guess you didnt even bother testing on mobile. Sorry for that rant,but we are in 2014,and I cant take more of that stuff.

Nope, can confirm it sucks on mac desktops too. At least with an Apple magic mouse.

I bet it looks brilliant in Lynx

Could I have this please with 802.11ac WiFi, 5GHz, preferrably supporting a 4x4 MIMO setup. I would love to have an open access point for my network. I like to have more than 300Mbps and to avoid the 2.4GHz network though even more. I understand this owuld be more expensive, but would be willing to pay a higher price.

  802.11ac WiFi, 5GHz, preferrably supporting a 4x4 MIMO
Retail price just went up to $300. Four dual-band wifi radios are expensive.

Can anyone comment on the read/write performance of SPI flash? Seems like it would be similar in performance to SD card, but without the wear leveling?

AFAIK, SD cards do not have wear leveling, SSD drives do.

Many SD cards have wear leveling built in, but most of the algorithms and CPUs used for the controllers are quite crap at wear leveling. If you start looking at more industrial targeted SD cards you'll find quite decent wear leveling.

I always find it hard to take things seriously when they are written in poor english. "Will coming soon" makes me worry about the quality of the rest of the project, maybe more than I should.

Thanks for pointing out, we corrected it. :)

It looks good now. Next time I will try your support link instead, but I am glad you saw the comment and got it cleaned up.

In the future it shouldn't be too hard to find someone willing to support and a good open source project with some proof-reading. I may not be the best candidate, but it would be a good way for someone to get started helping the project, and could make a big difference if you are targeting a larger audience.

Great effort, lovely little device. Building your own hardware is not easy to do cost effectively! But a few niggles: - Quoting RAM and flash in Mbits? Whilst that may be the norm for buying components, I'd argue most people familiar with OpenWrt and the Raspberry-Pi generation are going to miss this detail and think "Oh wow, 512MB RAM and 128MB flash!", when in fact it's 1/8th of that. - There's some mention of a st…

I once saw an SD card sold as "8gb" and thought it terribly expensive for that much capacity.

At least it wasn't "mb". I am not even sure how that would work.

SPI flash is usually NOR flash (not NAND like you'd find in an SD card or SSD). NOR flash is usually SLC and will take 100k writes/erases and is quite simple to access (as compared to MLC NAND which only usually takes 3k erases and is a pain to access comparatively due to things like ECC requirement).

SPI flash generally will do on the order of 0.5 MB/s erases, slightly faster writes, and somewhere in the realm of 4 to 12 MB/s reads, give or take. It's not high performance but it's simple, cheap, and low pin-count. The host controller is responsible for wear leveling, erasing each needed sector/block, and all writes, as SPI flash is unmanaged (compared to SD cards which are managed memory).

I bet if we could read their Chinese website, the copy would be perfect. Some manager who probably doesn't speak much English has tasked a random person on their staff who went to college in the US or UK with writing their English copy, without realizing the difference between "this person can communicate effectively 1:1 in English" and "this person can write formal English like a native speaker". In other words, a t…

They don't need better translation. They need a cultural liaison. You can speak English at a very high level but without deep cultural involvement, you won't know that "get out of the city" and "get out of town" have very different meanings.

When the peasants are revolting its very different from when the food is revolting!

AFAIK, SD cards do not have wear leveling, SSD drives do.

Most of them do some kind of wear leveling, but they usually use cheaper flash and less capable controllers and the controller algorithms are mostly oriented around making them usable for sequential writes as you see with a digital camera, not for making a good drop-in replacement for rotating disks.
