Hi Florian, Thanks you so much for your kind comments. Sure, I'll be adding more pictures and a video to show the RC in action, probably after I build some of the more advanced models. As for the TXT, to me it is a double-edged sword. I like the seamless mechanical integration, of course (although t...

Hi all, I was lucky enough to find an (almost) unused Super Trucks kit for a bargain. I added the standard motorization options to it which consist of a 8:1 power motor with differential as the main drive and a S-motor with a cogged track rod 38472 and a switch as a center stop for the steering, plu...

Hallo / Hi Rudi, I loved your Heron's turbine model, so I built a copy... just to find out the pressure from a single compressor (I only have one) was not enough to move anything: lots of air escapes between the fixed T-piece and the valve-hose connector. I solved the problem by adding a small piece...

Hi everyone, @ft-ninja, your solution worked brilliantly! I learned some "new" things in the process, among them a little bit about scp/ssh and how to run a Python command in the TXT4. WinSCP is not needed to upload the files anymore, I wrote a tasks.json to do it and run the code (with the help of ...

Hi ft-ninja,

Thanks a lot for your answer, looks promising! I'll try to find some leisure time this week, otherwise I'll certainly look into it during the weekend. I'll let you know via this thread.

Thanks again,

Rubem

Hello Holger + Vleeuwen, @Vleeuwen, I've already seen your post some days ago but it seems me that you are trying to run VSCode on the TXT (please correct me if I got it wrong), which should be quite interesting but it's not what I'm trying to accomplish. 260112_173538.png Here is a reduced screen o...

Hallo zusammen, Auch wenn ich mich hier wiederhole , bin ich immer noch der Meinung, dass fischertechnik keinen guten Workflow für Entwickler bietet. Grafische Programmierung ist zwar interessant, wird aber schnell umständlich und kann nicht alles. Deshalb versuche ich mich gerade an Python, aber RO...

(Deutsche Übersetzung im nächsten Beitrag) Hi everyone, At the risk of being ultra-repetitive , I still think that fischertechnik does not provide a good workflow for developers at all. Graphic programming is interesting, but starts to become cumbersome very quickly and cannot do everything. So I'm ...

Hi Stefan, Thanks for the compliments! About the ft-pedia article, I agree that the subject is interesting enough to warrant an article. Maybe I can find some time to write it after the holidays, let's see. I appreciate the invitation. I forgot one important detail: When a motor is de-energized, the...

Hi Florian, Exactly! The rotatable handles are kept in the middle position by default because of the springs inside the mini-switches. They are connected to horizontal plastic axles that rest on the switch buttons, one at each side. Here they are in their default position: IMG_20251221_175403.jpg Be...

Hi Florian, In essence you are right, whenever I turn two of the handles four motors are energized: two at the receiver, and two at the transmitter. The "trick" is that they turn just about 30° and stop (i.e. they don't rotate continuously), thanks to the connectors 15 with clips on each side that a...

Hi again, Here is a photo of the receiver (still on a plate 500) with the front panel removed. Harald, hopefully you can see that the connectors 15 with clips act as stops. And you added a good question: I don't hear any hum. Maybe because the switches are on just for short periods (less than a seco...

Hi Holger, Cheorl, Harald, Thanks for your answers and compliments. @Cheorl, you are right: The photograph seems to depict a model with an earth (or return) wire added, possibly to be able to rotate needles individually so that it can send additional codes. My model, however, uses just five wires li...

Hallo zusammen, Vor einiger Zeit stieß ich auf einen Wikipedia-Artikel über eine faszinierende Erfindung, die heute veraltet ist, aber in den 1830er-Jahren revolutionär war: den Cooke-Wheatstone-Telegrafen. Er funktionierte, indem Nadeln mithilfe elektromagnetischer Spulen so gedreht wurden, dass si...

Hi everyone, (Deutsche Übersetzung im nächsten Beitrag) Some time ago I came across a Wikipedia article describing a fascinating invention that is obsolete now but was revolutionary in the 1830s: the Cooke and Wheatstone Telegraph. It worked by rotating needles via electromagnetic coils so that they...

Hi Atzensepp, This is a very intriguing concept! I'd also like to see a video, if available. Alieson, Here's a video of my first version where you can see the chopper fly: https://youtu.be/Wk-IIUK-17I?si=Tkl7N9E5r7HPxMKy I still have to decide if I'll continue with the idea of the helicopter game or...

Hello bastizag, Maybe I can help. I'm currently working on a version of the old ft training robot . For this project I gave up on ROBO Pro Coding and graphical programming, it was becoming too complex. Now I'm using VS Code for development, plus WinSCP for auto-uploading the code to the TXT 4.0. Wor...

... 14) Also related to renaming / creating / deleting functions inside a lib: Sometimes all imports (from all libs) disappear from the UI. To continue, you have to close the RPC app and restart it. See example below. --------- Google Translate 14) Auch im Zusammenhang mit dem Umbenennen/Erstellen/L...

Hello/Hallo Holger and/und Horst, Some responses for you: I don't need to log in to GitLab all the time. Browser settings, perhaps? Yes, you are right. Fortunately, logging in is required only once. The annoyance is that even if we don't need to log in every time, the wizard step keeps appearing any...

Here is another bug, with graphical evidence: 13) If you rename lib files or functions, imported functions will appear grayed out, sometimes even after you import them again. Other functions may appear grayed out as well. ROBO_Pro_Coding_BxjVFoyXGM.png -------------------------------- Googe Translat...
