Gnuk 1.2.11
2018-11-12T06:36:41Z via Pumpa To: Public CC: Followers
Gnuk 1.2.11 is out.
It has a FST-01SZ support, which has ACK button.FST-01SZ with ZL271 (only) and magnet

Perhaps, this will be my use case for FST-01SZ.
I mean, I don't put another enclosure to ZL271 (the metal one). It's easier when something goes wrong and I need to connect SWD debugger.
A magnet which I use in the previous post is too strong for direct ZL271. It requires more power to remove off, which is inconvenient.FST-01SZ with ZL271 and metal enclosure, with magnet

Magnet is required to acknowledge the use of private keys.
Metal enclosures which attach to ZL271

ZL271 is attached. I drilled a hole to the left one.
Nice =)
Enclosures which attach to ZL271

Here are possible enclosures (bottom-right is ZL271).
Red one and blue one are original "wristband" versions.
Now, I consider using the metal version (left), drilling a hole for LED.
One of Bat man or Spider man would infringe copyright.

These are parts for FST-01SZ. Left is the metal enclosure, right is the connector to USB.

FST-01SZ prototype revision #1

This is the prototype. Functionality-wise, it should be OK.

I'm testing Gnuk running at 96MHZ with my proto-type board.
I named it FST-01SZ, where SZ stands for ShenZhen.EuroBSDcon and Gnuk Token

It seems that Gnuk Token will be distributed (possibly free of charge) at EuroBSDcon.
I was asked those who plans to do it.USB ID and the repository
2018-07-01T23:51:11Z via Pumpa To: Public CC: Followers
For some unknown reason, the maintainer has not yet registered our official USB ID to the database (for years).
https://usb-ids.gowdy.us/read/UD/234b
Today, I digged up the files (of physical papers), and found this one which was sent by FAX.
I wonder if it's enough evidence to be registered to the repo.De-facto standard of Wrist USB

In China, it seems that there is de-facto standard of PCB for the wrist USB.

I'm considering this type of USB device.Ben Sturmfels likes this.

Export Control
2018-06-15T01:18:09Z via Pumpa To: Public CC: Followers
I still remember that we had "non-us" section in Debian.
It was due to the export control.
Last month, I bought parts for USB flash memory in China (via TaoBao), to evaluate USB PCB design. But, due to an export control which prohibits exporting illegal content (copyright-wise and anti-china?), it was unable to deliver to Japan.
I had known that CD cannot be exported from China, but I didn't know USB flash too.
weird laws
I read a suggestion (in Japanese) to ask removal of CD when you ask exporting PC mother board from China. That's exactly to avoid export troubles.
It's pretty strange for me that most of PC are from China, and it comes with CD (of drivers, etc.).CVE-2018-0495
2018-06-14T00:55:34Z via Pumpa To: Public CC: Followers
I learned that OpenSSL has a practice not to assign CVE for side channel attack to localhost.
When I asked an allocation from Debian pool, my intention was one for libgcrypt. Then, reporter used it for multiple vulnerabilities among different libraries.Communication to Foreign Country

Installing "Taobao-lite" to my Xiaomi phone, I managed to order some electric parts. I used Chinese input method of hand writing.
It reminds me late 80's and early 90's when I was struggled to order T-shirt from FSF, using FAX.Tiny USB shell

I learned that there are common shell designs for Tiny USB shell (for WiFi or Blooth adoptor).
We can design PCB for those shells.

This is the one which I have an interest.
Finally, I found the connecter for this design:

It seems that the design is originated by Sony Vaio USB flash.
And compatible part is available for this design:

This is another one for "DT101G2", but different.
Please note that both designs requires a bit different USB type-A plug, which are a bit thin.McClane likes this.
USB PCB design for USB flash or USB key

In China, "semiproduct" is available even to individuals.
While I'm considering updating my USB PCB design, I realized that there are something like "de fact" standard; Here is the one which originates Kingston DT101G2 (I suppose).
Compatible enclosures for DT101G2 is available at taobao.com. But actually, there are two different PCB standards for that. This is the one, and I'm going to put another in the next post.Ben Sturmfels, McClane likes this.
Subway Line #4

Since train was on strike, my selection to CDG was "le bus direct". I bought the ticket on-line beforehand. I thought that I had well prepared.
The funny thing was, in the morning, when I went to the subway station to Montparnasse, it found that the line stopped from that day (May 19th). I turned to another station of line #13.
