We managed to get 72 Modules running - a new Australian record! although it did take a couple of days before everything settled in, and was running smoothly Oh, and in case anyone's interested... I had a RCX-powered ball counter running - 22k balls went past the counter, at a rate of between 1/4 and 1/2 ball per second. Once I saw it up around 3/4 bps, but most of the time it sat about 1/3.

Lasse D Posted January 28, 2017 Posted January 28, 2017 The pump mechanism I posted in my last message turns out to suffer from a lot of jamming in real life applications. I will look into ways to counter these jams. Quote
dr_spock Posted January 28, 2017 Posted January 28, 2017 I made something kind of like that for a Xmas gift exchange a few years ago. I made it 1x1 plate lower step at the input. It seems to help a bit with the jamming a bit. I like how you are using curved slopes. I am going to try that. Wonder Woman Invisible GBC by dr_spock_888, on Flickr Quote
Courbet Posted January 30, 2017 Posted January 30, 2017 Hello everyone, I have made instructions for Finn’s Steering Cup GBC module which is also seen in Akiyuki’s 2016 Brickfest video. I took the liberty to greatly modify the input and output parts of the module by building them according to Akiyuki’s standard to allow full compatibility with the others modules from the Akiyuki Project. As a matter of fact, you will find the PDF and MPD files in the same Akiyuki Project folder on Bricksafe with my others instructions files:http://bricksafe.com/files/Courbet/akiyuki-project/GBC_Steering_Cup_par_Superfin619.mpd http://bricksafe.com/files/Courbet/akiyuki-project/GBC_Steering_Cup_par_Superfin619.pdf Quote

He has a number of innovations on this piston pump mechanism, but the use of a wheel as the "head" of the piston may be the most important. I haven't tried it myself.

I timed a large Maico Arts contraption a few years ago and also got about 1/3 bps. Since a GBC will only go as fast as its slowest module, it follows that the slowest module on most GBCs averages 1/3 bps. I suppose the reason is that any module slower than 1/3 bps gets removed from the GBC. Quote

I suppose the reason is that any module slower than 1/3 bps gets removed from the GBC. I feel that the threshold for removal of a module is somewhat higher than 1/3. I'd be inclined to drop any module that couldn't do at least 2/3 bps (especially if it doesn't deal well with a buildup of balls). I think the discrepancy between slowest module and observed ball rate is down to ball spillage. Quote

I have had some trouble using brickshelf these last couple of days, so my work on showing the mechanism has fallen behind. I will post a new video this week detailling the mechanism using a more transparent module. Quote

kieran Posted February 10, 2017 Posted February 10, 2017 That's great, would love to see the 180 rotation in pneumatic as well Quote
lcvisser Posted February 10, 2017 Posted February 10, 2017 Wonderful Works very smoothly. A few non-lego springs in the bigger robot; I wonder if there's more, and what kind of pump is used... Quote

Pretty solid builds. Quote

BrianGT Posted February 13, 2017 Posted February 13, 2017 Anyone figure out a way to easily disable reverse on the 9V train controller module? I have been using it for my Ball Factory V2, but my daughter threw it in reverse yesterday, breaking the chains and messing up timing in a few other areas. I was thinking of putting nail polish over the reversing contacts on the PCB, but wondering what others have possibly done. -Brian Quote

That will protect the GBC even if someone attaches a different 9V controller to it. Useful if you take your GBC modules to shows. Quote
BrianGT Posted February 13, 2017 Posted February 13, 2017 I thought about a diode, but wasn't sure if the diode loss would cause issues with lower speeds. Quote

How about adding a mechanical one-way mechanism like a simple clicker? I use such a mechanism in my helicopter trailer and it works really well: http://c-mt.dk/instructions/instructions.php?model=HelicopterTrailer&page=1 See the next page of the link for how the mechanism is completed.

Requires a #1 Phillips screwdriver and a 1 x 6 brick. That's probably enough information for most people on this thread. :-) Or you could watch this amateur video.

Though it does mean that you can't, say, run something backwards for a second to deal with a bind. Maybe something with a shock absorber could be used to have a spring-loaded return-to-zero. Quote

doug72 Posted February 20, 2017 Posted February 20, 2017 (edited) GBC query:- I have come across a video of of a Mechanical chain module by Nxtstep101 and just what I am looking for for a mini GBC loop I am putting together. Would this work at an angle or even vertically ? Are there any instructions available ? How do you set the gears and levers? Edited February 20, 2017 by Doug72 Quote
