TP223 Touch Modules Offer Low-Power Switching Through Nonmetal Panels
A Hackaday report describes using inexpensive TP223 capacitive-touch modules as alternatives to mechanical switches in project enclosures. The sensors can detect touch through plastic, glass, or wood, although increasing the panel thickness reduces sensitivity; a smaller touch pad or an external capacitor can also shorten the sensing range. The report says the modules draw less than 2 microamps at rest. Two initially unsoldered jumpers provide four output configurations: the default output goes high while touched, jumper A inverts that behavior, jumper B toggles the output with each press, and using both combines toggling with the opposite default state. A small capacitor on the power supply is suggested to address false triggers. The article notes possible use in 3D-printed designs and as a power switch, but gives no independent measurements or detailed implementation results.
The article provides practical configuration and power details for a touch-sensor module, but offers no independent testing or demonstrated project beyond the described use.
A DIY Guide to Mirror-Finish Nickel Plating for Tools
The article describes [Kovancapol]’s process for applying a mirror-finish nickel coating to tools. It notes that the setup involves nickel sulfate and nickel chloride, glassware, nickel anodes, and a power supply, and points to a video in which the plated results appear visually polished. The piece presents electroplating as a process that may become more approachable once the equipment and materials are assembled, but it does not provide quantified coating performance, durability testing, or detailed operating parameters in the supplied text. It also raises possible applications, such as coating conductive 3D prints, as speculation rather than demonstrated results. Using nickel on PCB traces may be impractical because oxidized nickel is difficult to solder. The article mentions combining plating finishes but offers no specific tested examples.
This is a practical hardware-related plating demonstration with visible results, but the supplied text gives no measured performance or detailed procedure, and some applications are speculative.

Maker Builds a Retro Bluetooth Handset to Reduce Smartphone Distractions
Kevin Noki has built a retro-styled Bluetooth handset as an alternative way to handle calls without picking up a smartphone. The device is not a standalone cellular phone: it pairs with a separate, professionally approved phone, since the build has no cellular modem and custom hardware access to VoLTE is difficult in many places. Noki initially used an ESP32, but switched to a dedicated Bluetooth Hands Free Profile module after finding the audio quality too poor. The project video shows a case-design process that uses XPS foam and a hand-operated hot-wire cutter for quick form iterations, followed by a single 3D-printed final case; a simple jig is used to bend the dark acrylic covering the display. The design is offered on Noki’s website, while the article says the on-screen details may be enough for others to reproduce it without purchasing the design. The handset can reduce the need to interact directly with a phone, but does not replace one.
The project demonstrates a concrete Bluetooth handset build and practical fabrication choices, but it depends on a separate phone and does not provide cellular service or independently verified performance.
Three 3D-Printable Tombstone Tea-Light Holders Use a Fuzzy-Skin Finish
Maxx_Design has shared a set of three tombstone-shaped tea-light holders intended for 3D printing, with an alternative design that omits crosses. The holders are described as fitting round tea lights up to 40 mm in diameter and use a two-piece construction.
