 | | What AC adapter to use for RIS 1.0? —David Buhl
|
| | | I just got a second RIS, this one is the RIS 1.0 with the power adapter input. I tried to find that AC adapter on S@H , but couldn't find it. There is not even any info about it in the RIS 1.0 itself. All the info I found was, that I need a 10V 7VA (...) (24 years ago, 22-Feb-01, to lugnet.robotics)

| | | | | Hi, Seven VA stands for 7 volt-ampere. To arrive at the ma/A rating divide 7 VA by 10 Volts. In this case it will be 700 ma ( 0.7 Amp). I do not have the mindstorm, neither have I tried the 9 Volt adapter but in general a 9 volt adapter should work. (...) (24 years ago, 22-Feb-01, to lugnet.robotics)

| | | | | There's usually somebody selling the original Lego adapters on eBay for about $18. I suppose that's highish compared to a Radio Shack 9v unit. He must have a case or so - I bought 2 and they've been on regularly for a couple months. While I haven't (...) (24 years ago, 22-Feb-01, to lugnet.robotics)

| | | | | In a pinch - and if you don't mind spending some extra money - you can always by a train set like 4561 "Railway Express" for $129.99 or 4548 "Speed Regulator" for $41.99. Both are in stock at S@H, and include a suitable AC adapter. The first is also (...) (24 years ago, 22-Feb-01, to lugnet.robotics)

| | | | | (...) Interesting point. I haven't run the RCX with an external adapter yet and hadn't even noticed that it didn't come with one. The documentation doesn't specify the input requirements, nor does the RCX itself. I was alway under the impression (...) (24 years ago, 23-Feb-01, to lugnet.robotics)

| | | | | Thanks a lot guys I guess Lego should have thought about this and sell power supplies for their units (or at least let people know what kind they need) What I really wonder is why nothing has been done, I just got this unit 2 days ago, but Lego (...)

| | | | | (...) This is a follow-up to your earlier questions about what adapter to buy. I took apart my RCX this evening and started poking around inside. The bulk of the electronics is powered through a National Semiconductor LM2936M SO (Small Outline) (...) (24 years ago, 1-Mar-01, to lugnet.robotics)

The part I've found is the MELEXIS MLX10402. This is also a 16 pin SOIC and, based on a pinout (...) (24 years ago, 3-Mar-01, to lugnet.robotics)

I made a comment that I was surprised that there were no instructions in the manual (...) (24 years ago, 11-Mar-01, to lugnet.robotics)

| | | | Hello everyone, I've just signed up to this mailing list and it looks like there's a lot of cool information being passed around here. Anyway, I have an RCX 1.0 with the power jack. Some time ago, I noticed the markings in the plastic above the (...) (24 years ago, 11-Mar-01, to lugnet.robotics)
