Neat project from Instructables user OmA17:

The constant need to wave at the sensor to keep the light on became frustrating. Instead of discarding these lights and upgrading to expensive smart LEDs, I decided to save some money and modify their trigger circuits to extend their on-time.

For most motion-activated lights, this can be done by changing one resistor! So instead of throwing out your old motion lights, bring them back to life with this easy fix!

The write-up includes a nod to lady ada’s PIR Motion Sensor guide.

Ever worry about your bike getting stolen? The StealthTag is the perfect solution!

How it works: Simply insert the StealthTag into the stem of your bike’s front fork. The adjustable diameter (editable in Fusion 360) ensures a snug fit for most bike models. Once inserted, secure the two parts with a M4 screw and nut, compressing the bottom ring for a tight grip. With the AirTag tucked away inside, you can track your bike’s location in real-time using the Find My app.

This pencil case features two compartments to help you keep your pens, pencils, and other small items organized.

You can optionally use 8×2 mm or 10×2 mm magnets to keep it securely closed, so you don’t have to worry about it opening on its own.

It has been designed to be printed without supports.

It comes in two sizes:

Small: 185.5×63.5×50

Medium: 228.5×78.5×60

This is a 3D design of a Duplo-compatible window with shutters.

The window features a central frame with four square fix panes or two separate opening panes, flanked by two detailed shutters that can open and close, adding a realistic touch to any Duplo build.

The design is optimized for easy attachment to Duplo blocks, providing a sturdy and functional addition to custom creations, ideal for those looking to expand the architectural possibilities in their Duplo projects.

The CircuitPython community reached a big milestone together! There are 503 CircuitPython Libraries!

The CircuitPython Library Bundle and Community Library Bundle contain all the current libraries available for CircuitPython. CircuitPython libraries are separate files designed to work with CircuitPython code. CircuitPython programs require a lot of information to run.

CircuitPython is so simple to use because most of this information is processed in the background and stored in libraries. Some libraries are built into CircuitPython. Others are downloaded and stored on your CIRCUITPY drive in a folder called lib.

The full list of all the CircuitPython libraries contained in the library bundle can be found on the circuitpython.org libraries page.

Previous Milestones:

• 400 Libraries – January 23, 2023
• 300 Libraries – February 22, 2021
• 200 Libraries – December 10, 2019
• 104 Libraries – October 25, 2018

xsk8rat shared this project on Thingiverse!

The intention was to have a quiet sensor array in all the rooms to track the performance of the house’s environment over the internal interwebs.
The sensors (BME680 and RTC) go up in the hump on the top. They float around there, as mounting gets fiddly.
Run the fans off the 3.3V and not the USB rail as they can be a bit noisy at 5V. Or you can leave out the fan and adjust for the warming of the interior in the code.

NEW PRODUCT – Adafruit VCNL4200 Long Distance IR Proximity and Light Sensor – STEMMA QT

We’ve all been there. That thing is close but how close? When you need to measure a meter-or-so distance with reasonable accuracy, the VCNL4200 Long Distance Proximity Sensor from Vishay can do that for you. It’s excellent for robotic or motion-detection situations. And. if perchance you also needed to measure the amount of light at the same time, you’re in luck! The VCNL4200 can do that too, with it’s built in ambient light sensor (ALS)

The VCNL4200 is a powerful two-in-one sensor, with a proximity sensor that works from 0 to 1.5m (59 inches) and light sensor with range of 0.003 to 1570 lux. It’s the longest-range IR distance sensor we’ve seen other than the Sharp Analog distance sensors, and at a great price with I2C interface. Note that while the chip itself is specced for 1.5 meter distance measurements, that depends a bit on optimal lighting situations and high power configuration. We’ve found that 50-100cm is a good range to expect, and you won’t get a lot of accuracy/precision as the detection object gets farther away. We normally suggest ToF sensors for long precision measurements, but sometimes you want the low cost and simplicity of infrared. Also, you get a ‘free’ light sensor which ToF sensors don’t contain.

When Radio Shack sold electronics kits, they would include two documents. The kit step-by-step instructions and a Construction Hints document. The latter is a small four page guide showing:

• Tools needed
• Electronic parts identification
• Soldering tips for both through hole and PCBs

It also listed Radio Shack’s guarantee for possible part defects.

You can see a scanned copy of this useful guide below.
