Also I would like to meet and talk with the people who became friends of mine through the past Maker Faires in Czech Republic. I [16] => We will show mini balancing robots that have only two wheels and try to keep standing by moving the body back and forth. Some of the robots can be maneuvered by the wireless remote control. We will set up a small soccer field and visitors can try to shoot a ball to the goal. We will also show mini line-following robots. We will show another project of mechanical clock auto tuner. The device synchronizes an old pendulum clock with the internet time (NTP) by adjusting the pendulum cycle time.

[77] => Pro svůj projekt potřebuji wifi [74] => No. I just need it for my PC, USB power adapter, and battery charger.

He loves early music, and plays cello in a local orchestra. Projects include mechanical clock auto tuners, 2-wheeled inverted pendulums, small moving gadgets, etc. [320] => robotika [321.3] => arduino [321.13] => elektronika [321.14] => robotika [321.19] => hacky-a-vychytavky [287] => I did not throw away an old spring-driven pendulum clock that I found in an attic. But the clock was gaining or losing time too much, and adjusting the pendulum was a headache. I thought there had to be some way to adjust the pendulum automatically. I first thought about moving the pendulum bob up and down but it was not easy. Next I tried to use magnetic force and it worked well. I am working on adjusting other types of mechanical clocks such as torsion pendulum clocks, foliot clocks, balance-wheel clocks, etc. With regard to the balancing robots, algorithm is based on control theory, but in the real world it requires a lot of cut-and-tries. I really like the feel of accomplishment once it gets to be able to stand. [134] => In the past few years, I was not able to travel to Czech Republic due to COVID19. This year, I really hope to be there and present my projects. By the way, Czech baseball team came to Japan for the WBC games. It was a very nice game!
