The DIY kits do not require glue or additional tools. The components can be used with the tachometer, a mechanical model kit for learning. Model size: 24 x 10.3 x 12.3 cm. Package size: 20.5 x 18.8 x 6.3 cm. Number of components: 133. Assembly time: approx. 2.5 hours.

## Features

- The Tachometer 3D puzzle from UGEARS' STEM Lab collection is a fully operational DIY wooden model of a tachometer, ready for you to assemble. When the handle is rotated, movement is transmitted through a reducer, increasing the RPM and displacing twin weights in the centrifugal unit.
- A tachometer is a device designed to measure the rotational speed of various parts in engines and other mechanisms. It calculates revolutions per minute (RPM). The tachometer also measures and monitors load limits, in order to decrease or increase RPM so that the engine or mechanism runs within its optimal parameters.
- Connect the Tachometer to the Variator, creating a new mechanism The Variator-Tachometer system demonstrates the direct relationship between the transmission ratio of a gearbox, and rotational speed.
- Assemble the Tachometer and discover how it works. The model kit comes with a QR-code to the study guide about the mechanism, the principal of its working, the main characteristics, formulas. It also includes interesting assignments.
- Dive into augmented reality and look at how the Tachometer works. Interact with the model via a special AR application from Ugears. Point your tablet or mobile phone at a fully assembled STEM-lab model and the app will show you various applications of the mechanism you’ve just built.

## Questions & Answers

**Q: what does this do?**
A: The UGears STEM LAB Differential model features the updates made by Ferdinand Porsche in the 1930s to Onesiphore Pecqueur's 1825 design. The wheel, drive gear, side gear, locking clutch, and locking lever are all made to scale so that you can actually move the parts.

**Q: Can the Differential parts be painted and not interfere with the functionality?  Anyone painted theirs?**
A: Painting moving parts would most likely interfere with the smooth operation of the device.  You could possibly paint the stand or a stationary part.  Staining would be an option.

**Q: What kit attaches to this model in the instructions it shows another kit what kit is that?**
A: Curious ... I built (and love) the differential kit.  I did not purchase the variation.  But I do recommend you look into the STEM differential kit.  A very good product.

    Grandson loved it
  

*by E***N on Reviewed in the United States on July 19, 2024*

It taught us both a lot. Answered his many questions about manual transmissions. Well designed and sturdy. Everything needed is in the kit. Regarding complaints that you need strong hands/fingers to remove pieces, the "helper" tool (H) made piece removal easy, as well as assisting in many steps of assembly

    A Great Teaching Tool
  

*by N***O on Reviewed in the United States on June 28, 2024*

Love building these STEM kits from UGEARS. For myself its a great way to show my grandson how certain mechanical things work. The kit designs are very creative. The kits are instructive on the need to pay attention to details. The first kit I did taught me that. I've acquired certain tools since then to also help in building them. I went from constructing balsa wood airplanes to this and I love it!

    One of the best 3-D wooden puzzles I’ve  done
  

*by R***N on Reviewed in the United States on November 24, 2024*

3D wooden puzzles are my favorite hobby, I’ve assembled all different types from clocks to elastic guns and marble runs. This was definitely one of the funnest and neatest ones I’ve done, and the price was very inexpensive.
