Re: Fischertechnik wire supports.

And obviously you didn't party too much last night... Thanks Peter! No, there's not a lot of partying going on here. I have to live on a strict diet, heavy partying is out of the question. I always go to sleep early. I usually have new ideas in the morning. They're developed at night. But this chan...

Thanks Jan!

Yeah, that's a good idea. I'll adjust the opening.

Fischertechnik wire supports.

Fischertechnik wire supports. With many designs you have a lot of wires. To combine them together I made a series of wire supports that are 7.5mm wide. The internal diameters are: 5, 7, 9 and 11mm. I also made some adapted pins to mount the supports on all possible FT blocks. https://live.staticflic...

Re: Fischertechnik matching pins.

I haven't done a real force measurement but with the regular PLA they break down while with the PolyMax they have never broken down. The .stl files need to be placed in the right position with the printer software. Now they are vertical which is not good. I don't use supports here. The print tempera...

Re: Fischertechnik matching pins.

No PETG I haven't used yet, it has to be printed at a higher temperature. PolyMaker PolyMax is 9X stronger than the regular PLA and even stronger than ABS. My FlashForge Finder printer does not have a heated bed. I don't have any pins breaking off yet. All my FT parts are always printed with this Po...

Fischertechnik matching pins.

Fischertechnik matching pins. With these pins you can build almost all Fischer parts together. I use PolyMaker PolyMax PLA filament because it is very strong. The strength can be compared to the original FT pins. 3D printfiles on ThingIverse: https://www.thingiverse.com/thing:4074749 https://live.st...

Re: Two-way selector modules with servo.

Thank you, Peter. You can use the original screws that come with the small servos. This setup is quite simple and stable. With the extra detector in front you get even more control and counting possibilities. I use selective supports for 3D printing. In the two small holes at the bottom you may not ...

Two-way selector modules with servo.

Two-way selector modules with servo. The dimensions fit Fischertechnik. The servo setup is made in such a way that it cannot get stuck with a powerup. Sometimes this small servo goes out of position when applying the power supply voltage. There is extra space here. The flipper arm can easily be plac...

Re: IR detector for marble track.

Is ambient light really a problem in your application? Jan No, I haven't had a problem with that yet. The shielding is only a precaution in case there are problems with direct sunlight. For the time being, I don't mount the lids. Some precautions have been taken: - The IR photodiode contains an amb...

IR detector for marble track. This detector can be inserted anywhere on the existing marble track. It has the dimensions for the Fischertechnik blocks. The detector works with an IR led and a photodiode as receiver. The 3D print housing is made in such a way that it shields the ambient light as much...

Re: Multiple 3D print new marble run module

Thank you, Jan! I have a pro account at Flickr, so everyone can look at my photos and videos without any advertising in between. The neo leds are now built in a string up to 64 leds, but that can be expanded if necessary. The big advantage is that you only need a 3 wire strip to go from one to the o...

Multiple 3D print new marble run module

I made a new module for my big marble run. It's a double chain unit with super fast descent inside the 3D blocks. Because you can hardly see the marbles descending due to the limited opening between the blocks, a neopixel led string module has been added. Once the marbles are upstairs, they go down ...

I saw a question in the forum about the features of the power control. I just measured the signal myself: Result of a scope measurement on the 505283 Plus Power set from Fischertechnik. The intention was to measure the PWM signal. As a load I took a 44 ohm resistor which corresponds to a current of ...

Re: 3 to 1 flex rail 3D print

By mounting 3 blocks one after the other you get up to 7 flex lanes to 1 output. This way you can guide the many rails back to a central point. https://live.staticflickr.com/65535/48941531736_2cb869fd29_b.jpg Flickr: https://www.flickr.com/photos/fotoopa_hs/48941531736 3D file available on Thingiver...
