The author is undertaking a project to develop "Bridgetris," a game for the vintage 1985 BBC Bridge Companion console originally intended to teach bridge via television. To achieve this, the creator must master Z80 assembly language, reverse-engineer the system BIOS to allow custom code execution from cartridges, and perform hardware modifications like composite video integration.
- The device uses the TMS9129 VDP which features 16kB of VRAM.
- Original retail price was approximately £200 in 1985.
- Hardware was originally designed by a company named Heber Ltd.
- A composite video mod was implemented to improve visual quality on modern displays compared to the original RF output.

PWNSAT Team & Electronic Cats Research writes that PwnSat is an open-source, vulnerable-by-design cybersecurity platform bridging the gap between traditional IT security and specialized Space Mission Operations. It replicates a complete end-to-end space mission ecosystem comprising the Space Segment (CubeSat hardware), Ground Segment (RF Gateway), and C3 Segment (mission control integration).
- Employs Rockchip RV1106 Cortex-A7 with RISC-V coprocessors for flight logic.
- Vulnerabilities are mapped to the SPARTA framework for research relevance.
- Supports GNSS spoofing attacks against Attitude and Orbit Control Systems (AOCS).

This page details how to control shopping cart wheels using audio signals from a phone, exploiting the 7.8 kHz signal used for locking/unlocking. It provides audio files to lock, unlock, arm, and perform purchase checks on Gatekeeper Systems and Rocateq wheels.
This article discusses the MIT Artificial Intelligence (AI) Lab's 'Tourist Policy' and how it impacted students' access to its resources. As a high school student in Maryland, the author shares their experience of using the lab's PDP-10s over the ARPANET and how it inspired them to learn and contribute to the MIT community.

Introduction of Quansheng's UV-K5 handheld ham radio
- UV-K5's firmware stored in flash memory, allowing rewrites using USB programming cable
A growing community of hams adding software-based improvements and features
Examples of mods include graphical spectrum analyzer, text messaging between K5s, improved AM signal reception, and custom start-up messages
Web-based patcher/flasher allows easy installation of mods without exceeding memory limit
Potential risks of abuse and reliance on ham radio's honor system
Future possibilities of increased in-radio processing capabilities and app-like functions
