The idea of an exoskeleton, a worn mechanical device that augments human ability, isn’t new. Patents dating back to the 1800’s demonstrate concerted effort to meld man and machine. Sci-fi is littered with them, but until recently, they were mostly the stuff of imagination. Slowly, real, practical exoskeletons have been called into use in manufacturing, warehouses, search and rescue, and even the battlefield. Are we entering the age of the exoskeleton? Ildar Farkhatdinov writing for the conversation thinks so:
Devices like these are called human exoskeletons. They attach to parts of the body to create an external – or “exo” – mechanical structure. This powered frame enhances the wearer’s physical capabilities.
In physically demanding fields, workers are increasingly using these devices during strenuous tasks. IKEA has used SuitX exoskeletons for several years now. These assist warehouse workers with handling heavy materials. Ford, Boeing and Mazda Toyota have also all adopted the tech on some of their assembly lines.
Do you ever feel like someone or something is watching you? In the case of this project, it is! You can use a Fruit Jam running CircuitPython with a USB webcam to display monster eyes that gaze in the direction of motion captured by the webcam. The CircuitPython code utilizes Turbo helper modules to speed up tasks like drawing the monster eyes and checking for new motion in the camera frames.

Three different spooky tombstone tea-light holders, with an alternative version available without crosses. Accommodates round tea lights up to 40mm diameter. Two-piece construction with fuzzy skin texture. Stones print at 45° angle for optimal surface quality. Base plates use 150% flowrate with Hilbert curve pattern for the fuzzy top layer; lower stone portions must print without fuzzy skin for proper assembly fit. Pre-configured profiles with custom fuzzy skin settings and manual supports provided. Commercial license available via Patreon. By Maxx Design

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

Zed (@M-Abozaid) published a DNS ad-blocker on GitHub that runs on a $2 ESP32-C3 with no PSRAM. Most ESP32 DNS sinkholes load blocklist domain strings into RAM, which is why they need PSRAM. This one stores each domain as a sorted 40-bit FNV-1a hash in flash and binary-searches it. Over 140,000 domains fit in about 0.7 MB of flash, match in roughly 10 ms, and use about 50 KB of RAM.
The 40-bit width is a deliberate pick. At 141k domains collisions are near zero, and at 537k there is about one over-blocked domain. A 32-bit hash would save 20% of the flash but produce around seven collisions at 250k domains.
There is a UDP DNS sinkhole, a web dashboard at c3adblock.local, WiFi captive portal setup, and OTA updates for both firmware and blocklist. On a 4 MB board, firmware OTA needs two app slots, leaving about 1.3 MB for the list, so roughly 250k domains. The 537k “ultimate” list requires the single-app partition table. A printable case for the C3 SuperMini is included.
