Many thanks!

The game of Tetris for Teensy 4.1 Based on the work of Brian Lough Adapted for Teensy 4.1 by Maxim Bortnikov SourceForge page: https://sourceforge.net/projects/teensy-4-1-tetris/ Additionally, it comes with 5 start screens.

The hash latch is a lock that generates keys in a manner similar to how some cryptocurrencies are mined. It takes a string and brute-forces a prefix for it so that the hash of the string with the prefix has a certain number of leading zeroes. This approach allows the hash latch to be opened by...

The new version of the encryption software for Midbar (Teensy 4.1) V3.1 is out. I wrote it in Rust, a programming language designed to be "memory-safe" and prevent common memory safety bugs like buffer overflows. Even though this software should be more secure compared to the previous versions...

Another version of the AES-256 CBC Encryption Software For Midbar Teensy 4.1 V3.1 is available. It works exactly the same way as the one shown in the previous post. The only difference between them is that this one is written in GO. Check it out at: SourceForge...

Midbar (Teensy 4.1 Version) V3.1 is released. This version of Midbar can encrypt data that can be decrypted in the desktop app and vice versa. The new feature is available in the "Other Options" -> "Custom Key Encryption" -> "AES-256 CBC" tab. Check it out at: SourceForge...

Greetings, everyone. It's been a while since I last released a Teensy-based version of Midbar. I am excited to announce that Midbar (Teensy 4.1 Version) V3.0 is finally out! Midbar (Teensy 4.1 Version) V3.0 has a smaller and less expensive display than the previous Teensy-based version of...

Get familiar with Midbar without assembling it If you want to get familiar with the Midbar project without assembling it, you can play with its simulation on Wokwi (https://wokwi.com/projects/374498956604379137). Note that the Wokwi edition of Midbar doesn't include such features as...

By the way, I forgot to mention I've also included firmware for this version of Midbar without the RFID capabilities. You can find it in the "Teensy 4.1 Version/V2.0/extra/Firmware_no_rfid_with_EEPROM_with_type" folder...

The archive that you download from GitHub weighs 199 MB. As for using the part of the flash area designated for a program to store the user data, I prefer not to go into that depth, because it's much easier to use an external SD card or, as you've mentioned, just solder an additional QSPI chip...

Hello, everyone. Let me announce that the Midbar (Teensy 4.1 Version) V2.0 is out. That version of Midbar combines in it the password vault, credit card vault, phone number vault, note vault, data encryptor/decryptor, and data hasher. Aside from the fact that this is the first version of Midbar...

There was no conflict between the "ILI9341_t3" and the "USBHost_t36" libraries. I didn't get a chance to use them together. I failed to make the display work with the PJRC ILI9341_t3 library. It's the "TFT_eSPI" library that conflicts with the "USBHost_t36" library. As for the flash chips, I...

Thanks. The "B" button is used as a back button when you're in the menu. But if you're entering a text in a tab, then five successive clicks on the encoder button serve as the "Esc" button, and the "B" button works as a backspace. As for the display library, I wasn't able to make my display...

Greetings, everyone. Allow me to introduce you to Midbar (Teensy 4.1 Version). Midbar is a data vault that can also function as a data encrypter/decrypter. You can use it to securely store your login credentials, credit cards, notes, and phone numbers. Midbar utilizes The "3DES + AES + Blowfish...
