Any chance of buying Amp Hour swag in the new year?

My t-shirt needs replacing and I'm dying to get some of those cool looking log books.  Also, STICKERS!

As for spying and placing backdoors in hardware, on the 36C3 there was a nice talk on that subject, showing how advanced current attacks can be: Open Source is Insufficient to Solve Trust Problems in Hardware. It seems that being able to look at the PCB is no longer enough, even for attackers with relatively little resources. But, of course, it is better than nothing.

I understand there might be legal difficulties, but I'd be a fan of a Led Zeppelin instead of a Leaded. both work, but one is too perfect :)

Either way, where can I get one?




Also, if you find where that tree comes from, I'd love to get one of those too  :)

Dave asked whats the matter with the marker stuff.
In mechanic aplication its a trick to use marking color to find rubbing places.


I have a question about the Leded Zeppelin:
Is it allowed to use led free solder?
And yes, I love this Leded Zeppelin pun much more.

"LEDed Zeppelin", if anything! So many puns in just one badge!

A question related to the OpenDime shown in the video: is there an off-the-shelf way to connect a programmer to the castellated holes? Currently, I use Tag-Connect connector with corresponding pads for programming, but the customer asked me to make it possible to break off part of the PCB with programming pads after programming in order to reduce the weight and size of the board. Yes, few sq.mm and few 10s of milligrams are significant for this application. I wonder if castellated holes would be a suitable alternative solution.

The translator with the star signs is 100.00000% pure and utter :bullshit:. Astrology is in the domain of charlatans, liars, scammers and fools. Notice most of the people who believe this stuff have emotional and psychological problems. Hence why such rubbish is usually found in Australian women's magazines that are otherwise full of celebrity and royalty gossip.

I once went to a live dinner show and some bloke at our table told me he ran an astrology phone call service. I told him I reckoned astrology was rubbish and he said of course it is, but he sees himself providing a community service to those in need. He also said it was a very profitable business. I then ceased speaking to him.

Could someone educate me on the benefit of the Bitcoin USB stick wallet, with its "punch out a component to release the private key" concept?

Seems to me that, if someone finds or steals my "wallet", I am out of luck anyway. What am I missing? What additional level of protection is awarded by the punch-out idea? Thanks!

EDIT: Ah, I kind-of-see now. The thing is meant to be given away, traded or whatever, and the recipient is meant to trust the fact that no-one has read the private key yet, and that hence the opendime will hold its value: https://opendime.com/. I am not convinced though: Seems that a soldering iron and a bit of fresh heatshrink tubing is all that's needed to read out the key without leaving a trace?

The acrylic case is for the JYE DSO 138 kit that was featured not long ago.

I realise that most of you know the band's name is Led Zeppelin. Once the band had settled on the name, Jimmy Page thought that the name in print would be mistakenly pronounced "leed" Zeppelin. So "Led" is was.
