Nice Job!
That’s some good work, I’ve been kinda folowing this thread, it’s interesting
I like the milled tracks. Looks like it can handle lots of power. Will your mill take gerbers? Or do you export a DXF?
Thanks guys, but the pic’s a bit deceiving. It’s not a milled PCB, it’s plain old home-brew etching… We have a PCB router at work though, but I’m not allowed anywhere near it
Eddie, sounds like an interesting project! If you need some specific info on the board, gimme a shout, I’d be glad to help out.
Hrmpf… I hate how soldering parts to boards without solder mask makes them look crappy…
Anyway, I’ve started mounting some of the components, maybe, just maybe, I can have a working prototype by tonight… but i’m not making any promises
I wasn’t really meaning to pressure you into jumping on this if you were not ready ScuD. I noticed it had been a dormant thread for a couple weeks and wondered if it fell off the radar or you had made some progress and just not got around to posting. I am certainly capable of brewing my own if needed, but if you had something working that handled a bank of servos on an SSC-32 I wasn’t going to re-invent the wheel either.
Take your time man, it’s hobby not a job.
No worries, the only pressure i feel is self-inflicted
I just have a tendancy to start a project, then when it’s near completion some other project pops up and the previous one gets forgotten and gathers dust.
I’ve decided to get this one finished though, so a little nudge now and then won’t hurt
Just wondering btw… How much interest is there in a board like this?
For now I can only see it as being used in a johnny5-like robot…
I think a need for something like this goes well with ANY rover project. Rovers provide the option to do so many things since it can handle more weight than walker bots. The ability to safely power a variety of peripheral devices from a single board is ideal.
Personally I think it is a great idea if it can reliably run a whole side of a SSC-32 worth of servos in a full blown biped like Pete or Nick without dropping out. In theory it allows a 4S (16.8V) LiPO pack to run a biped, which makes a 2800mah 6V NiMH pack (about 17 watt-hours) at 9.4oz painful when compared with a 4S 1500mah LiPO or LiMn (about 23 watt-hours) at around 6oz. Since the peak and continuous output current rating of most r/c LiPO packs is way beyond what the input current would be in this configuration running two regulators, one for each side, off of the same pack should be a slam dunk. Add the third low-power pre-regulator for the VL inputs to the SSC-32 and ABB or WLAN board and you can easily get significantly more operating time per charge at less weight for the biped.
Oh They look like such deep tracks!
Very nice etching job.
Well I do agree on that one Best etch I made in years.
Forgot to change the pins though, they need bigger connectors so I drilled new holes to fit them, plus I only had a switch with smaller pitch so i snipped off a leg and drilled a new hole to fit it.
Now to dismantle the cnc router’s drivers for a shottky diode and some resistors and I can test the thing…
Only problem is, the inductor’s scrounged at work and I have no datasheet on it… I don’t think it can handle the full 5 amps
Oh voltage regulator threads!!
Yes, I agree, you make a board (or boards) that can provide qty 2 6V@10A rails, and one 6V@2A rail, from a 4S LiPo (especially if you make the LiPo portion cell aware), and I would gladly buy something like this! (Even if it cost $100, it would still be cheaper and more capable then 4 SportBEC regulators, which is what I am considering now.
I’m ordering in a new regulator. It’s designed specifically for providing a 6.0vdc output from a 2 cell Lipo input. The output is preset to 5.95vdc but can be adjusted from 5vdc to 6.5vdc.
Continuous current = 10 amp (7.4vdc in, 6vdc out, 74°)
Max current = 20 amp (1 minute, 7.4vdc in, 6vdc out, 74°)
Weight = 1.4oz.
Cost = $24.95
There are dual 22awg wires, which is sort of a cool way to connect it to the SSC-32.
Anyway I will be testing it with our Hexapods with a LiPo as the power source. I will let everyone know the results.

Edit: I updated the specs as my first purchase had the wrong specs listed on their spec sheets…
Let us know if it can be paralled too!!!
What! 8) Some of us want to run extreme bots
Was this custom built exclusively for Lynxmotion?
Naw, it’s just an RC thing.
From what I can tell, your existing regulator would be a better choice for 2S lipo since it can handle 10 amps continuous and 20 peak. Unless you are getting it because it has voltage cutoff circuitry. I’d rather have more amps.
I think the mfg is discontinuing the MX-05, so that one will be its replacement.
I found out that the spec sheet included with the regulator was incorrect.
Note the updated specs…
