(...) Hi Dustin, I am an EE. Before I give you some advice, I need a bit more information about 9750 (I have never seen one in person): - I see a power jack: I assume this powers the electronic circuit, not the loads, right? What voltage is applied (...) (20 years ago, 8-Apr-06, to lugnet.robotics, lugnet.technic)

(...) Wow - I remember those, we used them at school. Now why is it that Peeron do not have an entry for it under 9750? Those are also some big old capacitors, I would be inclined to check out their ESR (a rating of their health if you like) before (...) (20 years ago, 8-Apr-06, to lugnet.robotics, lugnet.technic)

| | Help with converting voltage on circuit board
|
|
I'd like to try to convert the output of the voltage on a 9750 from 4V to 12V (to control 12V trains :). I've taken a photo of the internal circuit board - my rudimentary EE knowledge leads me to be believe I need to swap out the transistors that (...)

Does anyone have a copy of or know of a good link to download the LEGO Engineer software - all the links that point to NASA sites don't seem to be valid anymore. Dustin (20 years ago, 7-Apr-06, to lugnet.robotics)

How about a biped that mimics human walking, i.e. uses its own inertia to catch itself? (URL) I recommend (URL) the videos from this mirror site>. This one's simple enough it might be possible to build it in LEGO. (20 years ago, 6-Apr-06, to lugnet.robotics, FTX)

Good news for anyone that already has the transformer for the AC powered RCX. Looks like NXT rechargable battery will use the same one! From the product page: "Use the 979833 Transformer to charge the battery " -Tim (20 years ago, 1-Apr-06, to lugnet.robotics)
