 | | Re: RCX 2.0 Power Supply
|
| (...) Indeed, the input capacitor of the RCX is rated 10V, so I would not do that for a too long time. This 1000µF capacitor, used to keep memory during battery exchange, is directly connected to RCX board supply input. By the way, this capacitor is (...)

| (...) You need to check the voltage while the PS is under load. Pretty much every power supply puts out more when the load is low or nothing. Has to do with loads of factors, but mostly quality of the PS (and (thus) internal resistance of the PS) (...) (20 years ago, 15-Sep-04, to lugnet.robotics, lugnet.trains)

| (...) On a marginally related note, does someone out there have the equipment to accurately test the output voltage of some typical dc power supplies like the one used for this external ps? I tested every ps I could find in my house (probably 20 or (...) (20 years ago, 15-Sep-04, to lugnet.robotics, lugnet.trains)
| | | | | RCX 2.0 Power Supply
|
| I've crossposted to .trains because this will be useful for those wanting to run LDCC with an RCX 2. Hi All, I've posted some photos on Brickshelf of an external power supply for the RCX 2. The nice part about the design is that program memory is (...) (20 years ago, 15-Sep-04, to lugnet.robotics, lugnet.trains, FTX)

|
| (...) Tim, I believe the practice with such systems is to cross the chains, which would reduce the sag on curves somewhat. (20 years ago, 13-Sep-04, to lugnet.trains)
| | | | | Re: Couplings for long overhang 4 wheeled vehicles
|
| Mind you, having had a look at my prototype again, it seems it used a centre buffer and side chains, the problem with that of course, is that for Lego 'corners' the chains would have to be so long they would drag on the track! Tim (20 years ago, 12-Sep-04, to lugnet.trains)
| | | | | Re: Couplings for long overhang 4 wheeled vehicles
|
| (...) I had considered the problem of relying on the friction of the axles/pegs. My thoughts were that the magnet to magnet join would actually be the weak link, although the coupling assembly might pull apart a little at a time with use. Presumably (...)

| | | | | Re: Couplings for long overhang 4 wheeled vehicles
|
| (...) That's right. The problem with that is you're relying on the strength of the axle and peg friction in order not to pull the couplings apart. With 12-wide stock there's some serious weight to pull! Also, your magnet holder is likely to rotate, (...) (20 years ago, 12-Sep-04, to lugnet.trains, FTX)
