Hi uffi, Your calculations make sense, although the coil resistance of the JF-0530B is not so low, my multimeter shows 5.5 Ω. I actually didn't measure the voltage drop, but I suppose my power supply can handle short peaks of higher current anyway because the solenoids remain powerful even when both...

Hello Uffi, I will also try to build a pinball similar to yours. Thanks again, uffi That's wonderful! I'll be glad to share some of my project files with you if you want me to, including the part layers (as shown here ) and the Arduino code (partially still under development, though). The TAU-0530T ...

Hello uffi,

The model I used is called JF-0530B, rated at 6 V. I posted more details about it here, just when I gave up on pneumatics for this project. At the time I measured the coil resistance, it's around 5.5 Ω. juh included a link to this solenoid on eBay above ↑.

I hope this helps!

Very cool rubem, you built it well, my compliment. :D Since I built one myself years ago, I know how much time you put in there.

And if electronics that have been announced within the last 6 months are involved, then we slowly move in the area of complex numbers and the box value gets an imaginary part.

Hi Arnoud,

Great! My first tests to the ft pinball did not look much different from your photos, with an external breadboard and lots of jumper wires... And I loved our "Nostalphone" and the video (I already knew the Zauberling, of course!)

Thanks for the photos!

Hi Arnoud, Great job! I was stumbling on it just now, and I have to read in more detail ASAP! :D Looking forward to some video and an article in the ft:pedia! Cheers, Arnoud Thanks for the compliments. I'm still working on the software part, there are some problems that need solving. The video will ...

Hi Peter,

Thanks for the compliments! I'm really flattered by all your kind comments

Best regards,

Hi Dirk,

Thanks for the invitation! I think this is a great idea, I'll be glad to share the details with the community. I'll PM you so I can have more info.

Cheers,

Hi, I found out the Neopixels don't work well as control LEDs. They often display the wrong color, light up when not asked to, turn off at wrong times. I made several tests but could not figure out a solution. So I've replaced them with regular white LEDs, I still had free ports in the child Nano. L...

Hi MoG,

If the micro:bit supports BLE why not? Just give it a try!

Yes, the specs say "Bluetooth 5.1 with Bluetooth Low Energy(BLE)", so it will probably work. I hope it's not too difficult!

Thanks,

Rubem

Hi, I already had similar code under https://github.com/harbaum/WebBTSmart. Here, too, you can see how to address the ft controllers directly from the browser. Great code! It doesn't even need a server, everything is done in JavaScript. Brilliant. Wouldn't it be easy to adapt it to run on MakeCode f...

Hi Frans, Looks great! it's always a pleasure to follow your posts and see your progress. Will you post a video at some point? <OT>I'd love to see what others model makers are doing too. I wish there were more posts at this subforum, after all making models is what fischertechnik is all about!</OT> ...

Nice photos! I wonder if it would be possible to share them in the picture pool along with descriptions (and name of model builders) if possible. I'm curious about the details on several of the models depicted. I have to confess that in some cases I'm not aware of what I'm looking at :D Best regards...

Here's a simplified animation showing some of the layers used for the pinball machine design, I believe you're gonna like it. Everything was done in Figma with custom ft and non-ft components.


Best,

Rubem

@Juh, I have some photos from intermediate steps that will hopefully clarify how the QRE1113 sensors were mounted: Outlane sensors.jpg Upper lanes sensors.jpg In the end I've replaced the upper lane LEDs with more powerful ones, but the general assembly remained the same. Best regards, Rubem

Hi, Thanks also to Karl, Frans and Stefan for your nice compliments! @Juh: Yes, that's exactly the solenoid model I used, which was designed for 6 V. It gets very hot when driven continuously at 18-19 V so PWM is a must. In my experiments I've arrived to 50 ms and 40/255 (~15%) as optimal values. 50...

Hi Jan, A - ma - zing, rubem! Wonderfully designed and executed, your description makes my fingers itch for a round or two... I hope we'll get to see a video of the pinball machine in action, soon? Jan Thanks for the compliments! I certainly will make a video at some point, but "soon" is a bit optim...
