Well I cannot test it here now, but I see no reasons why it shouldn't work. From our LUG meetings I found that the last command sent from either controller will be prioritized.

I just wonder what would be the result in case your moc is, let's say, crawling, then you push on another controller to go full speed and then release the control. Would it return to crawling speed or stop?

It will be at least a week until I can get a regular IR remote to test how both controllers act, but I'll be sure to report here when I can, unless another enterprising builder can find some answers first.

Also, I am pretty impressed with the Rechargeable battery box. I suppose I shouldn't be surprised that it can still feed devices that are connected to an IR receiver even when the "speed dial" is in the "neutral" position, but I had some LED lights connected directly to the box, and noticed variable brightness depending on how far I turned the dial. Learning the quirks of the different configurations and control methods of PF seems to be pretty fun in itself.

Quote: Also, using the Speed Controller with a Servo Motor sort of defeats the nifty auto-centre thing it does, but oh well. I learn the hard way.

When using a servo with 7 step speed controller, to get back to CENTRE position quickly, no need to turn the speed dial, just press the RED stop button below the SPEED dial and it will self centre again.

Yah, it's not really intuitive though, and it actualty pisses me off how quickly the servo motor can re-centre compared to how slowly it turns via speed remote control. I'm looking forward to getting the "regular" controller more than ever, since quick "nudge" control for steering is more important than "fine" control.

• How long does the power unit last say if you hook up 1 large motor and let it run until it dies?
  
• Dont know depends on the load of the motor, batteries, etc... Probably hours
  

There is no way to answer that. The time it takes will depend on the capacity of you batteries and the amount of load being driven by the motor. If there is no load on the motor, it would probably run all day. If it was working at maximum and drawing an Amp, it might last less than an hour if you are using cheap batteries.

When i drive my motorised unimog (1XL for drive, 1L for stearing, 1M for PTO and pneumatic pump and 1M for 2speed gearbox) I can drive only 1 hour just driving in the lowergear on heavy offroad with rechargeble AA bateries 1.2V 2300mAh. So ifyou want to do some heavy offroading you should have a few battery boxes.

Also if you buy rechargeble batteries for your lego, BUY a batterycharger that has 6 or more slots for AA and/or AAA batteries. I have one of BaseTech which is a mark of Conrad.be (http://www.conrad.be/ce/nl/product/200112/Basetech-Oplader-BTL-12-voor-max-12-batterijen-gelijktijdig-9-V-blok-Potlood-AAA-Penlite-AA-BTL-12?ref=searchDetail), this one has 10 AA/AAA slots, a discharge function and a carcharge adapter to.

If you have less than 6 slots you will have to take days to charge your batteries.

Or maybe yes because Wedo sensors can be labeled by shift-click on it?

I my asking in this thread considered hijacking thread, if yes, sorry and will not do again. If no, hope to get an answer

Please keep in mind that 99.5% of Lego users will never have heard of Wedo, and of the 0.5% who have heard of it, most of them have never seen it. Wedo is a very obscure topic, even in a Lego forum. You probably aren't going to get any response asking these types of questions in these types of topics. Best to use a custom Wedo topic so those who actually know something will find it. You can probably use a single topic for all your Wedo questions.

I have every Technic set ever made and I've never seen a Wedo part.

Hi there

emilyan could I ask you for a copy of your word document based on the answers to this thread ?

I too am interested in getting some PF stuff however unsure what each of the components do.

regards Paul

There's an official Lego PF page:

And you can download the element specs and IR control protocol.
