I have not really done a lot since the last one. Except move the supports for the long front arm slots so that they face forward(ish) as opposed from the centre point. This will enable the use of arms coming out to the front instead of the side. Someone mentioned it somewhere and it was a "Oh yeah!" moment. Also James from the UK R2 Builders mentioned that he has had to strengthen his shoulders so this has been done also.
Even though the dome is untouched, I wanted to get the displays working so I have been soldereing the components on. In line with everyone else I put some LEDs in to make sure it all worked and only 1 set of them worked!!!!! After about 18+ hours of investigating, swapping bits over, resoldering, testing with a multimeter and writing down what IC pin went where all with a X10 magnifying glass stuck to the eye, it transpires that there is a small break between pins joining the first IC to the 2nd (and thus the 3rd). A small jumper wire soldered on and hey presto! we're in business. Now all I have to do is file the flange on the 135 LED's down so the bezel will fit.

So far about 50 done.
I have been wondering about the centre wheel and found a site on fleabay which was based a few miles away. Deciding to pop in the way home from work I managed to get a centre swivel 100mm castor for £6. It did look like I was going to have a smaller 75mm wheel for a time though. Bigger is better - especially when I get the suspension on it.

Time to go and file another few LED's.
