DIY Mechanical Bionic Hand

▲ Source: Twitter

A prosthetic hand controlled by myoelectric signals based on Arduino and a series of sensors, capable of holding cups and glasses without issue.

The prices of such myoelectric bionic hands are generally very high (some abroad cost hundreds of thousands), and we also have companies in China focusing on this area (such as Shanghai Aoyi Information Technology Co., Ltd.), but the prices are still relatively high.

If we could produce such myoelectric bionic hands at a lower cost, it would be fantastic for families of people with disabilities or stroke patients to use.

I hope technology can help more disabled individuals live normally.

VR Haptic Gloves

A functional glove that allows you to feel the shape and resistance of objects in virtual reality!

Currently, most VR haptic glove products are very expensive and are aimed at commercial use.

The intention of this project is to create an affordable yet functional VR haptic and finger-tracking glove that everyone can afford, and can be used in actual VR games. Source^[1]

DIY FPC at Home

Since developing my own bio-impedance measurement system requires flexible printed circuit boards (FPC) as sensors, I found that the prices online were not cheap, so I tried to make flexible printed circuit boards using materials available at nearby stores. Source^[2]

LattePanda Computer – LATTEintosh

A personal computer based on LattePanda 3 Delta, themed after the Macintosh 128K, which the author named “LATTEintosh”.

Cyberdeck

A heavy Cyberdeck, also an experimental sensor and hacking platform, is still under construction.

Mainly uses Raspberry Pi 4B, 10-inch TFT HD display, Logitech wireless keyboard, running Kali Linux.

Supports 4G LTE, Wi-Fi, 7 USB 3.0 ports, and 5 Gigabit Ethernet ports, and can connect various sensors due to the GPIO of the Raspberry Pi. Source^[3]

NASA Launches Lunar Orbiter “Orion”

According to the plan, NASA launched the new generation heavy rocket “Artemis 1”, which will send the “Orion” spacecraft into the designated orbit during this flight mission.

Of course, there will not be a real manned return to the moon during this flight, as the spacecraft will carry 3 human models equipped with detection instruments, executing a lunar flyby mission and then returning to Earth. If all goes well, NASA will conduct a manned flight mission on “Artemis 2” in the future.

The picture shows NASA’s “Artemis 1” lunar rocket standing on launch pad 39B at Kennedy Space Center, waiting for launch after multiple delays.

A Startup Plans to Send Robots into Space to “Clean Up Trash”

Rogue Space Systems, a space startup based in New Hampshire, plans to launch orbital robots using SpaceX and ULA (United Launch Alliance) rockets next year.

The company currently has 4 robots in production, designed to perform different tasks in orbit to support satellites and clean up space debris.

Orbital debris has become a significant issue for the aerospace industry, with some spare rocket parts and defunct satellites floating in space, posing a threat to rockets and satellites that will be launched later. Some objects even re-enter the Earth’s atmosphere and fall to the ground. Rogue founder Jeromy Grimmett stated that they have signed two launch contracts with launch service provider Exolaunch, with two robots on each launch.

Later, launches will be conducted on ULA and SpaceX’s spacecraft, both carrying one robot.
