Aachen Maker Meetup #165: Creative Projects and Collaborative Innovation

The 165th Maker Meetup at the i10 department of RWTH Aachen University brought together another exciting collection of projects, reflecting the diverse talents and creativity of the maker community.

Jan's Projects:
Jan showcased a set of innovative 1.5V Li-Ion batteries from XTAR, paired with the VX4 charger. These batteries prevent deep discharge with integrated electronics and deliver consistent 1.5V until their last 5% of capacity, at which point they drop to 1.1V to trigger a low-battery warning. This feature is ideal for devices like Eve thermostats. Jan highlighted that these batteries currently offer the highest capacity in their category and are available for 5–6 € each. Variants with USB-C charging are also available for added convenience:

Levin's Projects:
Levin presented an optical tracking system using retroreflective markers. The system is designed to create a DIY VR controller, demonstrating innovative approaches to motion-tracking technology.

Andreas' Projects:
Andreas displayed his laser-cut and printed programmable blocks, designed to simplify programming for beginners. The blocks are compatible with JavaScript and Python and are part of a project to control a small vehicle. This collaboration with Stella aims to provide an engaging introduction to coding and robotics.

Birgit's Projects:
Birgit showcased several creative and technical projects, including:

• A woven "fabric" made from 3D printer purge lines, creatively repurposing waste material.
  
• A 3D-printed emboss roller, using a design found on MakerWorld.
  
• A concert ticket holder, 3D-printed in 1-2 layers, with a TPU band serving as a closure mechanism.
  
• A laser-engraved depiction of the Aachen Cathedral. She used multiple passes with the laser cutter to prevent overheating and achieve intricate detail.
  

Martin's Projects:
Martin presented a diverse range of projects, including:

• Mario-themed refrigerator magnets created as a personalized gift.
  
• A 3D-printed acupressure platform designed for therapeutic standing exercises.
  

Fabio's Projects:
Fabio demonstrated a durable and functional soldering iron holder, 3D-printed using PLA CF (carbon fiber-reinforced PLA).

The 165th Maker Meetup highlighted the ingenuity and innovation of the Aachen maker community. From practical tools to artistic creations, the projects shared provided inspiration and insight, continuing the tradition of fostering collaboration and creativity.
