| | How to fix a failing touch sensor on Spybotics
|
|
Hi all, I recently got hold of a - previously ignored - Spybotics model (I never really considered them to be of interest until I got one cheap and found the kids like it). Yes, they are fairly outdated, however they hook up to my Mac just fine over (...) (14 years ago, 10-Mar-11, to lugnet.robotics.spybotics)

Hi all, yes I know, this group has been dormant for quite a while - however when digging through my older Mindstorms items last weekend, I also found two cybermaster units and became curious if they were still operational. The software is of course (...) (14 years ago, 10-Mar-11, to lugnet.robotics.cybermaster)

(...) I have come across some industrial heater controls. To get the heaters at part power (to run them in a closed-loop temperature control), a method of burst firing is used. The circuit measures the zero crossings of the AC supply and turns the (...) (14 years ago, 25-Feb-11, to lugnet.robotics)

| | Anyone else tried the Firgelli actuators?

I decided to spring for one of the expensive Firgelli actuators, and just gave it a quick try. I either got a broken unit, or it is the worst piece of junk anyone has ever made for NXT. First of all, you command it to move a distance, not command it (...) (14 years ago, 25-Jan-11, to lugnet.robotics)

Dear Brahm, We know we are not supposed to do this on this forum, but we shall do it anyways because our gratitude towards you is more intense than just a 5 star rating.

(...) No, purely resistive. Although it does have a "boot up" time, I think it's just due to heating up the element. I'm not completely sure if the element will respond better to a "dimmer" type set-up (running it at less than normal voltage) or a (...)

I'm not an expert on power circuits, but a google search turned up this web site with a number of interesting power supply circuits (there is a search option).
