Yes, it can be done, that is one of examples - change speed of "1 second tick", in my example is how to get it faster, but the same is, to have it slower. But you will still have 12 rotations of minute hand will done 1 rotation of hour hand. That is not how 24 hour clock usually works, they have 24:1 ratio.

Hmm, I'm mostly playing with electronic, to have 24h clock you must change gearbox ratio. For example remove every 2nd tooth on one cogwheel :)

Hi audreyobscura,Not sure I understand what do you mean by "horizontal photos". I have lot of photos, then Iuploaded some "more ortogonal", as well as some "landscape" photos. I added "landscape" videos as well.Is it OK for you?Jindra

Thank you

Hi, your lucky day: https://www.instructables.com/Simple-Electronic-Speed-Controller-ESC-for-Infinit

BTW: the ESC is available in last number of this magazine page 23:

Hi, I did extra small and extra cheap ESC (electronic speed controller) for servo with removed electronics (no modification - remove all and connect directly to motor terminals). See picture. (the pin header is for programming only and it is no necessary to solder it). It have configurable speed curve, zero position, direction of movement etc.The only problem is, that I "sold" the know how to "Praktická elektronika" (http://www.aradio.cz) magazine, then I can not publish it for now.

Nice, Once you looking for new version of gcode plugin working well with last version of Inkscape, then: http://www.fucik.name/hw/laser/jfu_laser.php

It is very interesting way how are you working with PCB. Very "clean" work.BTW - you can have two enhances:1 - add serial port + arduino boot loader to be cool in those days2 - use charlieplexing to have more leds see: www.youtube.com/watch?v=E3LK-E9tigs (8 pins = 56 leds) :)But in principle it is very good project with excellent result.

Nice project, but look like this very old fashion description of charlieplexing. :)http://nekropolis.cz/CharPxYes, I understand, the old one not using any *uino, then it can not be cool. From the other hand, it have matrix 8*7 and using rotary encoder :) (and it is cool)
