Seven segment LED displays are brighter, more attractive and provide a far viewing distance as well as a wider viewing angle as compared to LCD displays. The major drawback of using seven segment LEDs is they are resource-hungry. Time-division multiplexing is the most common technique of interfacing 7-segment LEDs to microcontrollers. With this technique, an 8-digit seven segment LED display with the decimal point requires at list 16 I/O pins of the microcontroller, which is quite a lot. Consequently, their use with low pin-count microcontrollers (such as PIC12F series) is not practically feasible. SPI7SEGDISP8.56 is our latest version of the MAX7219 based serial seven segment LED display module that will allow you to add 8 digits of seven segment LED displays to your project using only 3 I/O pins, and provides full control of all the digit segments including decimal points. You can even cascade two or more of these modules together without sacrificing any extra I/O pin.

Uses only 5 pins and SPI.

Welcome to N1ghtw1re, a sanctuary for the seekers, the rebels, and the dreamers navigating the labyrinth of the modern digital world. We are an anonymous collective dedicated to empowering individuals to reclaim their privacy, autonomy, and freedom in an age dominated by surveillance, algorithms, and corporate control. N1ghtw1re is more than a website—it's a living hypersigil, a digital beacon for those ready to challenge the status quo and embrace the tools of liberation. Through shared knowledge, subversive creativity, and intentional action, we aim to dismantle the systems that seek to exploit us and rebuild a future where technology serves humanity, not the other way around. Join us in forging a new path. Together, we’ll uncover hidden truths, defy expectations, and reimagine what it means to be free in the digital age.

Simple minimodem BBS with a 3d printed acoustic coupler case. The acoustic coupler was designed to hold a USB speaker and microphone, which you can buy from Adafruit.

Requires Linux. PJSUA and minimodem must be installed. The BBS uses shell scripts and javascript to relay messages via minimodem over VoIP. On the server side, start PJSUA then start the phoneMonitor.sh script. Minimodem is set to run at 100bps. Edit the shell scripts if you want to change the baud. You will need to edit the clientSide.sh script, minimodem -A alsa option should match your USB microphone and speaker. Use arecord -l and aplay -l linux commands to find their card numbers.

An acoustic coupler is a useful tool for dialing up to the internet when you have a phone available, but no phone jack to plug into. I "built" my own acoustic coupler out of a phone and a 9 volt battery. I say 'built', but really, there was almost no building involved. Here is a crude drawing of the acoustic coupler hooked up to a laptop and ready to connect to the internet through a phone booth.

Departure Mono is a monospaced pixel font with a lo-fi technical vibe inspired by the visual constraints of early command-line and text mode user interfaces. Think 80's dot matrix printers, ancient documents, airline tickets, and receipts.

Excels with tabular data. Includes characters for drawing in text mode. Seems to cover the classic IBM 256 character set. Includes .woff and .woff2 versions for web design.
