Well, Rubbee X has done some more miles now on our rather rough cycle ways & some roads. And it has a problem!
I put it down to bad design of the bottom of the case where the brass inserts fit into circular bosses, and the battery base cover.
Details:
After working well all day I went to switch it off, but no amount of holding in the power button made it go off. Its red rear light array shimmered and was unresponsive to me using the apps power adjust or any other buttons, it was in a trance!
The app gave a message about 'too many pixies' and that was all it told me.
On attempting to undo the 6x battery compartment screws I discovered that some had bent under force and others had become undoable because the brass inserts were no longer held in place due to the boss they were screwed into had cracked open.
Clearly the batteries were not held in place by the flimsiness of the design of the battery cover and side panel bosses.
My guess is that the bouncing batteries had allowed the voltage to the control board to fluctuate so badly, the board had gotten into a lock up. This was proved when the batteries finally came out and the board reset to normal.
So what to do? Rubbee.co.uk website is now just a single page that gives an email address,
[email protected]. The rubbee.com website isn't yet uploaded and is in Lithuanian! So nothing useful is there.
I have asked by email if they have any modifications or developments to the casing to offer me, but that was only yesterday & no reply yet.
So I'm 'going offroad' on this, at least in planning my own ideas. I want my Rubbee to work because its a clever little thing & I like it!
First Idea.
Base - Have a 3D printed base made that also has an external flange that stretches over the underside all round to keep out water & muck. The current cover leaves a gap all round that asks for trouble.
Allen Screws - dump them! getting them in & out is horrible & they + brass inserts aren't up to the job of holding the batteries properly in position.
Add straps or Zip Ties that wrap around the top of the Rubbee body (under the piston and also behind it) to keep the new & stronger base in position when batteries try to break their way out as terrains get rough!
We'll see what happens!
