Hey guys, can we meet up this wknd to figure out the mounting holes for the fuse box, circuit boards and other wiring needed for the electrical network

Hughzie commented 11 years ago

We're already planning on finalizing the CAD Saturday afternoon so that's a perfect time for you to pop in

Sorry about missing Saturday.....

Anyways, I'm working with Radd to have a suitable fuse bus (a lower amp version of this : http://www.powerwerx.com/fuses-circuit-protection/raised-ganged-6-circuit-atc-fuse-block.html#desc )

I think he will be back to me tomorrow, then you should be able to mark the holes. Also, I am still trying to figure out the power situation and have submitted the question to a few beagleboard forums so I'll see if anything pops up

Radd did not get back to me on this today, I will bump him

Received this from Maxon:

Please consider there is always a reason why the fuse has been broken. A suppressor transient diode protects the circuit. Make sure this component is still in full function. Original Fuse: Manufacturer part number 0467 03.5 NRHF Secound Sourse: part number USF0603 3412.0121 If ever possible send the unit for repairing. We will check the whole circuit.

So each EPOS is protected by 2 individual fuses. It may be overkill to then have another bank of 3A fuses in a central fusebox of the hexapod. However, we need a 6 pt bus anyway to distribute the battery power and making this a fusebus will not make it any larger (might add a trivial amount of weight), thus I think a fuse bus is still fine especially given the fact that I asked how to change out the fuses in case one blew and they said it was best to send the unit in for repairing. I'd much rather have a little more (redundant) external protection than have to deal with the EPOS itself (and especially their service department)

@Hughzie @towlett

Can you guys confirm that this 10 pt (Allow up to 10 individual circuits) fusebox will fit.

3.35" x 3.74" x 1.45" and weighs 14 grams

As soon as you say it is okay, I will order it

Hughzie commented 11 years ago

@PayneTrain @towlett

That will fit on the middle plate okay, 2 things with those dimensions could fit on the middle plate (1 to the front and back of the middle line) You mentioned needing a breadboard as well, right?

PayneTrain commented 11 years ago

Yeah just a 2 3/4" X 1 3/4" solder board which we will plug all the CAN networks into. it's ideal if this board is in the middle of the hexapod

Hughzie commented 11 years ago

Perfect: fuse box on one end of the middle plate, solder board on the other, motor controllers to the sides. None of that should interfere with the slots for adjusting the spring-joint fulcrum (4" apart)

PayneTrain commented 11 years ago

Purchased fusebox - looking into .250" connectors/ 3A fuses

PayneTrain commented 11 years ago

Re-opening because there might be an issue interfacing the fusebox and joint.

@Hughzie let's chat about this
