Production of the case for the robot with a limited budget. Vacuum forming

Production of the case for the robot with a limited budget. Vacuum formingHow to show investors a beautiful robot? Develop a beautiful body. How to do it while there is no investment? I tried to briefly describe my path. We develop Golf Ball Robot at the driving range . 3r3208. Without a beautiful body is very difficult to explain how the robot will look. [/b] In this article I will tell you how for 24000 rub. get a case of 1000mm x 800mm x 250mm, as well as what kind of rake we collected along the way. Perhaps this will help you avoid our mistakes.

In the EU, require the right to repair major household appliances

In the EU, require the right to repair major household appliances  
Source: Schraube locker !?
And not only them, but also other household appliances, but activists of the “right to repair” movement decided to start with refrigerators. They managed to collect more than 100 thousand signatures under the relevant document and even get a vote in Brussels on the change of 3-3313. Legislation 3r3356. related to the repair of household appliances.
The main task of European activists now is to achieve such changes so that home appliances can be repaired on their own, using parts provided by manufacturers. The traditional practice of manufacturers not only household appliances...

Xiaomi wireless devices in the smart home ioBroker

Xiaomi wireless devices in the smart home ioBrokerGreetings to all home automation lovers. I decided to share the experience of using Xiaomi wireless devices with ZigBee interface. I, frankly, oppose the use of any wireless devices in any automation, from serious large-scale process control systems to small automation systems like fire alarm systems or smart homes, but Xiaomi solutions bribed with low cost, availability, excellent design and many positive reviews from users, I decided to try.
 3r33655. This post should be taken as step-by-step instructions for integrating ZigBee devices into the infrastructure of a smart home. Described ...

The article by Mitch Altman, the inventor who invented the universal remote control for turning off the TV-B-Gone TVs, and the organizer of hacker conferences 3r395. 3r3114.  3r3114.  As a child, I was drawn to the music, and I was amazed at the sounds of the synthesizer 3r317. Moog 3r3117. from the 1968 album Switched-On Bach . I needed to learn how to extract such sounds! Thus began the training and production of synthesizers with a lifelong parallel to my ...

Flamethrowers, Santa Claus on the tank, Bigfoot, Baba Yaga on Endurik (and, possibly, Jetpack) - all for the kids for the new year

I found a training ground in the center of Moscow, check it out.

Site requirements were: 3r3785.

Development of buck-converter on STM32F334: principle of operation, calculations, prototyping

Development of buck-converter on STM32F334: principle of operation, calculations, prototypingIn my last two articles, I talked about the power module and the control board based on the STM32F334R8T6 microcontroller, which were created specifically for implementing control systems for power converters and electric drives. An example of a DC /AC converter was also considered, which was a demonstration, not a complete construction. Now it's time to do something simple, but useful, and most importantly complete. 3r31196.  
Most of the issues related to the project and power electronics are related to specific topologies: someone is interested in knowing the PFC control algorithm...

We study nitrogen lasers - part 2. Longitudinal discharge lasers

We study nitrogen lasers - part 2. Longitudinal discharge lasersIn the last part of We looked at examples of home-made and factory designs of nitrogen lasers with a transverse discharge, and it was this topology that became the most popular for replicating home-craftsmen. And here are its advantages:
Simplicity. As mentioned above, in many cases even the design of an improvised simplest nitrogen laser operating in atmospheric air is fully applicable, even with quite serious scientific work in the laboratory. 3r388.  
A rather serious output pulse energy is tens of millijoules at large installations. 3r388.  
A very short pulse duration, in some ...
