I bought 2 RSM's from ebay just before christmas for a total price of £110 both in working order(one had a broken lcd scene which I have since replaced). I was just going to add a serial hack them both tonight and when I open the 1st up to my suprise it alreadt has the serial hack cable already solder. Below is a photo.
Am I luck or what? Well thats not the end of it. I then open the other RSM which I bought at the same time and guess what, Yes the serial hack wires have been added to that one already as well. below is the photo.
That's amazing, how luck is that, it's save me a lot of work. I think going on how well the soldering is done on the hack and that both cables are identical this must have been done at the wowwee factory. Has anyone else opened there robot up to find the serial hack wiring is already done for you?
I have already ugraded one of my RSM's to Firmware 2 and have added the serial hack with both wired and wireless connection. Tonight I did the same setup on another bot other than the firmware upgrade which I will do shortly. I have put the bluetooth chip above the media board to the back and as it has and led on it I can see when it is powered up frombehind the bot. As you can't use both the wired and wireless chips at the same time to comunicate to the robot I have added a switch to cut power to the bluetooth chip which then allows me to connect via the USB-TTL module and communicate with the robot that way. Below are some pictures to show the of the mod have done.
