I still make them! Check out bitpunk.fm if you want to hear an audiozine. I publish the digital version as a podcast but the original looks like the image below:
Generally the answer to this is no. Almost all hardware wallets are paired to the mcu to the secure element.
So hww are realizing this is not a great UX, however it is good for sales.
So I think there are some HWW working on be factory reset able.
But yeah, I don't follow coldcard but my guess is you are screwed.
Yeah lol, this. The Certificate Authorities are a cabal and are gatekeepers.
Imagine nostr but you had to first get your npub signed by a nostr authority-- that is PKI.
We are seemingly doing just fine without them.
I sometimes use my steamdeck to boot tails to use sparrow wallet. Works great.
It's better if you have a dock though.
Unlike most hardware wallets, I can see the output in HD.
Analog solutions to problems are often simpler at the cost of precision, which is a feature.
I would let my coffee brew for 2 minutes. I used my watch sometimes even digital timers and they would beep.
But I would never service the timer right away, it was more like oh thanks for letting me know.
I switched to this sand timer. It's 2 ish minutes. Turns out, what I really wanted to know was has it been at least 2 minutes and this works perfectly.
I'm appreciating more of these analog life hacks each day.
Do you know Travis Goodspeed and Great Scott Gadgets have hacked these and done many talks about it? You should check it out.
If you don't know Travis he does many ham hacks like the Goodwatch, which is a ham radio transmitter watch.
I was on a submarine. The coffee pots are industrial defense contractor grade drip machines with nuclear reactor power heating elements.
You order coffee thusly:
"I would like a 2 and 2."
That means, 2 seconds cream 2 seconds sugar.
It can get worse.
Pitfall! Those scorpions tho
So I had previously tried taking some data and frequency modulation at 15kHz or so. This effectively hides the signal in the upper band of the cassette. I'll try this in software today.
But I'll need a FM demod circuit in front of this guy.
Yeah that makes sense. Here the mcu controller doing the decoding I'd already more powerful than the C64 :)
Link is below to the original blog post, github link is in that post.
So, the PET and others use a type of FSK. I tried that originally as well. It's not only slower but not as reliable I think.
I think perhaps it was easier to do fsk back then? Idk.
But in the discussion you'll see the benefits of manchester are I think we'll suited to this medium.

Yeah! It works! Cassette to data, decoding in real time at 3k baud!
Some improvements to be made but super happy with this. This means I can encode a message to a cassette and then decode it without having to digitize the audio, as it's being digitized as it streams in.
So it could be nice for offline storage of sensitive data. This is the physical layer so of course its possible to add authenticated encryption as well.
For example you could leave a cassette at a dead drop with an ecash token on to pay your raw milk dealer.
The encoding mechanism is differential manchester encoding which means it should be more survivable on different cassette decks. I have some bad ones so I will test it.
In this short video I also explain it, although I think I mi's speak the band rate. It's 3k baud ish.

I still use a FM transmitter in my house so that all my speakers are in sync. Cheaper than Sonos, no subscription, and my neighbors can tune in too.
They got super popular during covid for churches were people would sit in their cars in the parking lot and listen to the live sermon.
I'm digitizing this recording to CD also for my mom.
These recordings of the Jerry Garcia Band are kind of lore in the cassette world. Imagine a concert where the first rows are just filled with people and their recording gear. Which they called the taper section.
What I like about cassette recordings are they aren't perfect. I was having this conversation just yesterday with nostr:nprofile1qqsv025hmnjh5mml40stydgh9lhwse83z2mxlqpf7xmfk3mvp5fvsyqpp4mhxue69uhkummn9ekx7mqpzemhxue69uhhyetvv9ujuurjd9kkzmpwdejhgqg5waehxw309aex2mrp0yhxgctdw4eju6t0mcktn9. Each recording has an imprint of the person doing the recording. Tape hiss or no, EQ going in, how hot of a level etc...
It's more like handwriting whereas digital is like a printer.
Also, this tape is over 40 years old and sounds amazing.
Anyway, maybe I should do a short article on this for the next issue as to justify putting the music on there 😀
Happy National Radio Day! We don’t listen to the radio anymore. 😊

I know what you mean by these comments and I don't disagree. It's a centralized, one way, transmission on FM.
But it still makes me sad. Radio, as a technology, is amazing. And I really liked the idea of low power FM stations serving very local communities.
It has as much a business model as cassettes but still, fm receivers are so cheap and easy to access compared to phones with decent internet.
Like imagine a HD radio broadcast with a QR code for zapping. It could be done.
My mom doesn't have a cassette player so I put bitpunk.fm on "digital vynl" for her.
