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im nächsten Beitrag) Some time ago I came across a Wikipedia article describing a fascinating invention that is obsolete now but was revolutionary in the 1830s: the Cooke and Wheatstone Telegraph.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...

Hi / Hallo Lutz,

I'm always interested about how to use remote controls to operate ft models. Great stuff, congratulations!

Mich interessiert immer, wie man ft-Modelle mit Fernbedienungen steuert. Tolle Sache, Glückwunsch!

Best regards / Viele Grüße,

Hi, I'm starting this thread as per Calliope's idea . Here are some easily reproducible ROBO Pro Coding (RPC) bugs: 1) Create a new code file in the lib folder, create one or two functions, go back to the main file, and create blocks for the functions from the imports menu. Then return to the lib an...

Hi again, Here is my latest version. This is my attempt to recreate the helicopter game. You can see most of the new additions: a TXT4, a potentiometer to control the propeller speed, three landing pads with light sensors, a reflective panel behind the chopper wheel, some obstacles, and LEDs to sign...

Hi, Some time ago I have recreated items 154521 and 154544, plus the soccer field, in vector format. They are available here , under folder Artwork. Hope this helps!

Hello Arnoud,

Wow, amazing. Again

Hi Florian,

It's great that you're trying to work on your concept. I'll be delighted to see your own helicopter model. I see the radius change as a big challenge, but you might as well start with a basic model like mine and proceed from there. Please keep us updated!

Thanks,

Rubem
