| | | Hiyall. I just got my Lugnet posting access working again, so I thought I'd post a here's-my-Lego-webpage link. Ignore as you see fit :-) One of my areas of interest is building solar-powered robots (and the necessary custom mindstorms parts to make (...) (19 years ago, 7-Feb-06, to lugnet.robotics) !

| | | | | (...) Whooaaa!!! very neat stuff here, very good documentation of your projects. I especially like the solar powered RCX with auto-shutdown/resume... Any chance to get the schematics of you Geiger counter interface? Congratulations, Philo (19 years ago, 7-Feb-06, to lugnet.robotics)

| | | | | | (...) Thank you :) I don't have a schematic (more like a few pages of illegible notes :) and the gieger counter sensor isn't something that's easy to make a useful schematic for anyway because of unusual parts that vary in key properties, and the (...)

| | | | | | (...) I fear all I can do is gawk in astonishment. Getting a HV sensor to work off the RCX is truly an amazing acomplishment. But you've gone well beyond that, with the solar panel (I'd seen the earlier one on eBay), the powercan... and the (...) (19 years ago, 8-Feb-06, to lugnet.robotics)

This would not be difficult - if you scroll down to the bottom schematic, it is colour-coded into sections according to function, with the last third of the circuit being all that you need to make a switch to activate and run the RCX from some (...)

You've done some really nice work, that the rest of us would now like to copy :-). (...) That's (...) (19 years ago, 10-Feb-06, to lugnet.robotics)

| | | | | (...) Very, very impressive !!! As Philo, I also would like to see more details of your designs. There is one question that is tacking me: When we were working over our "Mars"-project, we tried to use the LEGO solar panels, but we could not extract (...)

The difference in energy you get from sunlight compared to artificial light is massive. Running solar from (...) (19 years ago, 8-Feb-06, to lugnet.robotics)

This is quite difficult, because if powered down, the RCX not only shuts down all its peripherical devices, but also sends the H8 micro-controller to (...)
