Date of Start: 2025-03-24
Date of Finish: 2025-03-24
Type: Software
Status: Closed

Summary: Project Rhenium is a set of low-weight java tools.

Characteristics: Rhenium consisted of a calculator, a password generator, a disk monitor and a cypher encryptor/decryptor. All four software were wroten with java AWT toolkit, promised its compatibility and simplicity.
Reminder: This software required Java enviroment to run, please install one from Oracle!

Project Title: Project Midland
Date of Start: 2025-03-24
Date of Finish: 2025-03-24
Type: Hardware-Chip
Status: Closed

Summary: Project Midland (TianGuang) is a PCB-Based ROM storge module. Capacity is 256-bit.
Schematic: Data were able to be stored on PCB board by On/Off of fuse circuit built into the board.

Fuse Structure:

Mod I: “I” shaped, parallel placed 200μm~150μm width fuse. Fuses were designed as thinner in the middle for a efficient and gentle meltdown. Capacity is 8-bit, size 20mm*17mm.

Mod II: “U” shaped, parallel placed 120μm width fuse. Capacity is 64-bit, size 20.75mm*12.5mm.

Mod III: Groups of eight 120μm~100μm width “S” shaped fuses, shared cathode pins along a longer and wider central power line. This design help to save space, and “S” shaped fuse can meltdown more efficient. Capacity is 256-bit, size 26.8mm*14.8mm.

Project Title: Project Espro
Date of Start: 2023-09-26
Date of Finish: 2025-02-07
Type: Hardware-Device
Status: Closed

Summary: Project Espro (JiGuang) is a nano board based on ATMega328P-AU.

Characteristics: Compare to a normal Ardrino Nano, the Espro board is equipped with an 3.3V power adapt module and improved 5V power supply. Espro also have two extra configurable power output ports, and an brighter programable LED light.

Project Title: Project Hydrogen
Date of Start: 2024-02-22
Date of Finish: 2025-03-05
Type: Hardware-Device
Status: Closed

Summary: Project Hydrogen (GuangMing) is an MicroDrive device, with maxium capacity of 8GB.

Characteristics: Hydrogen drive have size similar with an short PIP flash drive, but with an ultra-high edurance and better environment tolerance. MicroDrive have total life cycles of 70,000 P/E, and able to work under temperature of -25°~85° Celsius.

Project Title: Project Trident
Date of Start: 2023-12-21
Date of Finish: 2023-12-25
Type: Hardware-Device
Status: Closed

Summary: Project Trident (XingHe) is a port protection device.

Characteristics: Trident installed fuses and Zener diode for all four lines of an USB-A port, as most computer motherboards are lack of surge protection for data lines and older device used by my school may have none even on power lines. Switches installed on board were also able to physically turn On/Off data lines to prevent unauthorized use of flashdrive and possible BadUSB.
