Hi use Glycerin on rubber tyres to bring them back to life.

Hi grum64 Oh I don't know what about "Grum's Shed - Where No Project Is Too Hard"Regards.

Hi The round axle end is 3mm

Cracked U joints, I put small rubber O rings on my U joint collars it stops them cracking but allows enough flex to push on an axle.

That's OK I am glad it worked it took me awhile to find it out if I remember brixcc will still upload the firm ware even if it shows an error.

Hi nxtstep101 use brixcc to download the firmware, use an earlier firmware version then when you have it up and running you can upgrade to a later version. I have done this with two of my NXT bricks. that went into SAMBA mode

Hi I have that serial adapter and it does not work with my RCX that is another reason I use an old laptop with a serial port.

Hi Have you any Arduino software installed on your PC if so this is clashing with the RCX software. It took me ages to find this out on my PC in the end I installed RCXCC on an old laptop and that installed the firmware OK.

Hi I had the same problem, do you have the Arduino IDE installed on your PC if so this is why the NXT is seen as a Bossa port the Arduino IDE takes over the NXT drivers. I uninstalled the Arduino IDE but would still not work. I put an older hard drive in my laptop with XP on and installed the NXT software I was then able to re-flash the NXT brick using Bricx command centre.

Hi I have not used my RCX for years but looking at it yesterday I tried to download the firmware using a USB to serial adapter on a Windows 7 laptop and three other computers no good. I loaded Bricc onto an old Windows XP PC with a serial port and re-flashed the firmware no problem. It looks like the RCX is not found with a USB to serial adapter. Paul.

Hi grum regards No it is my Mother in law I agree with an earlier post it should jump forward it would scare the kids to death Ha Ha

Hi DaveI had exactly the same problem it was the Arduino IDE interfering with the the firmware update in the end I installed BrickCC on an old laptop and that downloaded the firmware OK. I had even tried to uninstall the Arduino IDE on my desk top PC still would not work.

A Clam shell grab would have been better it could then be rope operated.
