ElBear ACE-Uno — первый запуск в Mac OS

В статье рассмотрим, как начать работу с ElBear ACE-UNO в Mac OS. Постарался для вас сделать выжимку, чтобы можно было скорее приступить к работе с платой и потратить на это на пару-тройку суток меньше) P.S. Для пользователей Windows статья также может быть полезной.

Does anyone use OpenBSD to program their Arduino devices? I tried using the makeEspArduino package to build uLisp for the T-Deck, but encountered problems. For details see:

Thank you for your suggestions. Please boost.

Hallo an die Maker-Gemeinde da draußen

Habt ihr einen Tipp für mich, mit welchem Buch/Heft/Zeitschrift/Website ich am besten mit einem niederschwelligen Einstieg in die Welt von #Arduino und/oder #ESP32 starte?
Vor allem die Elektrik-Grundlagen, die Anschlüsse und das Auslesen/Ansteuern von Zeugs sollten dabei gut mit abgedeckt sein (High-Level programmieren kann ich schon).

Ich nehm gerne auf ein Tipp für ein gutes Starter-Set

An eInk, Wrist-Mounted, TOTP Generator

https://shkspr.mobi/blog/2023/07/an-eink-wrist-mounted-totp-generator/

Behold! Thanks to the power of the Watchy development platform, I now have all my 2FA codes available at the flick of my wrist!

HOWTO

This uses Luca Dentella's TOTP-Arduino library.

You will need a pre-shared secret which is then converted into a Hex array. Use the OTP Tool for Arduino TOTP Library to get the Hex array, Base32 Encoded Key, and a QR Code to scan into your normal TOTP generator.

Add the Hex array into the code below.

To check that it is functioning correctly, either scan the QR code from the OTP Tool above, or use the Base32 Encoded Key with an online TOTP generator.

Here's how the code interfaces with the Watchy:

You can grab the full code from GitLab.

I'm not very good at C++ - so please let me know what terrible mistakes I've made.

Is this a good idea?

Well... Yes and no.

TOTP is a strong-ish form of Multi-Factor Authentication. It helps prevent attacks where someone already knows your username and password. Having a convenient way to get your TOTP codes may make you more likely to use them. It also prevents you from getting locked out of your accounts if your phone dies or is stolen.

Convenient security is good security.

But... Having them on your wrist for everyone to see? I've deliberately made the font as small as I can so it is only readable up close. However, if someone is shoulder-surfing your details, they may well see your wrist. The watch isn't encrypted - so even if you hid the codes behind a button press, anyone who steals your watch will have your codes. If they steal your phone, they need to get through your PIN / biometrics.

Who are your adversaries? If you are trying to evade state-level actors, thieves specifically targeting you for your crypto-holdings, or an untrustworthy spouse - this probably isn't a great idea. If you don't use 2FA because you don't keep your phone with you - this will probably increase your security posture.

Ultimately, all security measures are a trade-off between convenience and control.

I'm in my 60's, and I've gone and bought an official Arduino Uno R3 Starter kit.

I know as much as a slug, about programming, and electronics. But hoping it isn't too late to learn.

Project 2 Spaceship Interface; wired it up, and typed in programme (can't see how you learn by just using the free sketch), and it worked... 😱

Hackaday: A Scanner For Arduino-Powered Book Archiving. “Scanners for loose papers have become so commonplace that almost every printer includes one, but book scanners have remained frustratingly rare for non-librarians and archivists. [Brad Mattson] had some books to scan, but couldn’t find an affordable scanner that met his needs, so he took the obvious hacker solution and built his own.”
