There is more on the subject in issue 3/22 of Make.
It has something of magic: you circle an object with an ordinary camera or a special depth sensor and a digital twin is created in the computer in the form of a 3D file. You can reproduce them with a 3D printer or build them into computer games or virtual reality environments.
For the new Make issue 3/22, we tried out the latest 3D scanning technology in the form of the Revopoint Pop 2 and the OpenScan Mini, among others – and we are fascinated. Some of the test results can be inspected online live in 3D; in the magazine, on the other hand, you can read in detail how the scanners work and how they can be operated – and also how you can alternatively get 3D models of real objects without any special hardware.
Also in the issue: The coffee tabs empty warning
Everyone knows that: Exactly when you need the coffee the most, the pads are gone and you have twice the stress – namely no more coffee and worry about the refill. An intelligent solution is needed and there are detailed assembly instructions for it in Make issue 3/22: A load cell determines the weight of the remaining coffee tabs supply, an ESP8266 calculates the number of remaining tabs and sends the life-threatening fall below the minimum amount reminder emails to the people who have been sentenced to fill up. In addition, live data on the current status is transmitted on a separate channel via MQTT. In this way, the worried coffee junkie is always informed about the availability of his confidence stimulant.
