New MetaClockClock V3 finished with 60 Clocks

The holiday break at the end of the year is always a good time to finish projects started during the year. This one is about my ‘MetaClockClock’ Version 3.

Building a DIY High Density Philips Hue LED Stripe

Philips Hue Smart LED stripes are great, but they have a disadvantage: the LED density is rather low: one LED cluster (WW, RGB, CW) every 55 mm. This leads to the problem that individual dots might be visible if the LED stripe is directly visible. Even if the LED stripe is used for indirect ambient light it means that individual dots might still be visible on the wall or ceiling. The solution is to create a ‘high density’ Hue smart LED stripe:

DIY ‘Meta Clock’ with 24 Analog Clocks

Human since 1982 claims

“Human since 1982 have the copyright to works displaying digital time using a grid arrangement of analog clocks…”

I’m not a lawyer, but without obligations (imho) I have removed the content.

DIY Wireless Magnetic Levitating Moon Lamp

If your child is making a special wish, you will do everything to make it happen, right? So my daughter’s wish was a ‘moon lamp’. And here is it: a magnetic levitating (MagLev) wireless moon light:

3D Printed SMT Cut Tape Holder

If you follow me on Twitter, then you are aware that I’m working on a larger project building an SMT pick and place machine :-). The fun with this project is that it includes electronics, mechanics and all kind of 3D printing and laser cutting. That machine picks SMD components and places them on a PCB. One sub-project is to build a SMD cut tape holder:

Custom 3D Printed Magnetic Encoder Disks for Robotics Projects

I’m making great progress with the firmware for the new Mini Sumo Robot (see “New Concept for 2018 Mini Sumo Roboter“). The goal is a versatile and low-cost Mini Sumo robot, and the robot comes with the feature of magnetic position encoders. In a previous article I have explained how to mold custom tires for robots (see “Making Perfect Sticky DIY Sumo Robot Tires“), this article is about how to make DIY Magnetic disk encoders.

SQUIX ESP8266 based E-Paper WiFi Weather Station

I’m a fan of all kind of weather stations. When Daniel Eichhorn twittered about his new version using an E-Paper display module, I immediately preordered one. I decided to build a station with a custom enclosure, so here is my version of a 3D printed version, featuring magnets so it can be attached to the fridge:

Custom 3D Printed Enclosure for NXP LPC-Link2 Debug Probes

I love 3D printing as it enables me to create custom enclosures for all kind of projects. The NXP LPC-Link2 probe is great, but it lacks a protective enclosure. So I decided to create a custom enclosure. And as 3D filaments are available in different colors, I experimented with red and black and custom painting:

3D Printed Sumo ToF Blade

ToF (Time-of-Flight, see “Tutorial: STMicroelectronics VL6180X Time-of-Flight LIDAR Sensor“) sensors are fun: they measure the time the light takes to travel to an object and back again. That way they can measure the distance to object with a millimeter accuracy. An ideal sensor for a battle robot: πŸ™‚
