Re: New controller
it get's warmed up by our hands around it.. ie not very! they're rated at 30A, so we're not even close to it's max power rating |

Re: New controller
So no thermal paste and heatsink is really required?? |

Re: New controller
That's my instructions for you as clear as mud.  No wonder I get them confused.  I think I was thinking about turning brakes off and coast on, or was that the VCR...

Re: New controller
Richard, Great stuff here. Shawnster, check it out! They even have an Electronic Thumb Controller for you so you wont have to worry about playing with your Cox. |

Re: New controller
Is there an updated circuit diagram? Cheers Richard |

Re: New controller
Ok, got my vero-board, PCB type connectors, 100 1/4 watt resistors and 50 1/2 watt resistors, the only bits I'm missing are the values for the potentiometers ... ? |

Re: New controller
I am using 1K Log pots with a resistor across them. It does depend on the value and number of the other resistors you are using as it is all about balance. I have 9 resistors in my wiper each 33 ohm as is the R1 and R3. I do not have an R2 but this is where I put the choke if I have one. Across the sensitivity pot is 100 ohm resistor. Across the choke I am using a 330 ohm resistor. I am loosing interest in having a powered coast/brake controller as I just haven't found a car that needs it. So instead of attacking a pot I am using just a 1K log pot. It seems to give me good control of the brakes but more testing is needed. I have also been looking at using diodes for a brake controller. I like the theory so I will probably build one and test it out. Anyone know a free easy to use software for drawing circuits and I will lay out what I am doing. |

Re: New controller
Dia will do the trick: http://dia-installer.de/index_en.html There is a standard "circuit" installed, but there are extended sets here: http://dia-installer.de/shapes.html It also does flow charts, logic circuits, etc Can output in PNG or JPG format

Re: New controller
Hello Found this topic via Richard's post on auslot. I have 2 Parma controllers that the resistors have died in and this looks like a really good option for making new controllers - are there any of the transistors still available? I would appreciate another diagram - I am electronically challenged but willing to have a go I would appreciate any assistance that is available - diagrams, parts lists, etc thanks David |

Re: New controller
David I should be able to help you out with all three requests. I will pm you (in the next few days) re a couple of transistors. I am working on a diagram, parts list and some instructions which should sort out the build issues for you. Geoff |

This is another controller mod - converting an AFX type to a 100 Ohm resistor ... Enjoy! Richard [Attachment: Aurora_100Ohm_Controller.PDF (1.29Mb)] |
