Advice on wiring a direct power switched miniUSB plug

[deevergote]

Idk, Im not a fan of wiriing anything into a permanent power state.

I understand if you know what your doing it will work out, but it leaves the door open for a drain, and also for being stranded which im not a fan of.


BTW....that Rasberry pi is fucking sick.

How did you find that?

My buddy Dino posted about it on Facebook (dude races a built EvoX... really awesome guy). There are likely better options, but I love the fact that it's so small and simple. And cheap! It'd be a fun toy to wire into the Fit, hooked up to a small screen (that I could even velcro to the dash...) It'd be ideal for my work needs, as I really don't need a whole lot of power (I know I'd be using Linux, but I'd deal... just couldn't do All my work in-car.)
I think it'd also function well enough as a tuning computer in the CB7. Basic tuning programs don't need much. For $35 or so, you can't beat it!

I'm still thinking it'd be most useful to wire it directly to the battery with a fuse/resistor/whatever is necessary... have it on a switch. I think as long as I remember to turn the switch off, fully severing the connection, it won't drain the battery. Plus, how much power could that thing really take?

Honestly that is the perfect answer to your needs.

With some patience you should be able to get a Windows XP distro running on it.....anything is possible.

Heck the website says it plays HD video so it is quite powerful for it's size.

I want one but IDK what I would use it for.

And I bet if you used Linux(assuming youve never used it before) you would love it!

I know you like simple setups and it can't be more simple then Linux.

This site has several 12v to 5v converters. This one is 3amp max output. I assume you can run a switch in there on the output.
It looks like a two wire in and two wires out.

not sure about how to get that to mini usb, but I know somebody smarter does.

That's a start. Thanks!

not exactly what youre doing but along the same lines, I needed juice for a battery operated FM Modulator. 3 volts . found an old cd player power adapter (some are 5v @ ~500mA too) this one was 4.6 or so. Gutted it from the lighter adapter housing, soldered on new supply leads put a piece of 1" shrink wrap around the small PCB and hooked the output to the prongs for the battery's in the modulator. Now I do power it from the the remote turn on from the amp, but if I couldnt do it that way Id wire it to 12v fused switched or not, and definitely if using a switch put it on the ground side. =)

Found this on ebay while searching for a temp monitor.

It looks to have a USB plug built in. And it's cheap.

Not wanting to support hong kong but its an option

[deevergote]

Nice! That could be exactly what I need! Run wires to that, with a switch to disconnect the power when necessary...

It's unfortunate, but most cheap electronics are coming from Hong Kong now. I've bought a number of things from there already. While I'd prefer to support US sellers and manufacturers, the Chinese prices are a fraction of the cost (and the quality, but that's to be expected.) For things that are more "toys" than anything else, I'll go with cheap Chinese, and replace them with quality parts sourced elsewhere once I decide I'll use it. My in-car video camera, for example. It has already died... but I like and use it, so I'll be investing in a better one soon!

I bet it won't be long before the Chinese start reproducing the Raspberry Pi for like, $20 or less. The Pi's price is already quite low! I'll support the real deal there, though... because it's a charity, and the price is still reasonable.

My head unit has the USB plug and all I have to do is turn the key to Ignition I and it's active. So I got a working power source.

I agree and to be honest I don't know how they make any money on these things. Under $5 shipped from across the world.
Who knows

Our cost of living is real high compare to over there. Also the amount of profit might not be worth while to us but to them every profit amount into bigger profit. So their way of thinking vs ours is different.

This is different, though. Well, in a way. That plug COULD be used, I suppose...
Not applicable in the Fit at the moment, though. The stock head unit doesn't have that! The CB7 will be getting a new system once it's back on the road, and that's likely going to be a key point in buying one.

Computer bits really aren't all that expensive to make. The majority of the price you pay for new stuff is paying for the research needed to develop the advanced technology. Once something is developed, the Chinese can copy it for pennies.

I bet the Chinese are the first to fully clone a human being. The clone will be retarded, but it'll be a full human being!

cut the usb cable from the end and strip the black and red wire if you need it for power use only. step down the power and tap into cigarette lighter. remember to fuse. if you want it wired to be on all the time then throw a switch in there and route wire directly to battery

not hong kong, hong kong could be their distribution hub and most international mail gets routed through hong kong

the raspberry pi is made in taiwan. first few were prototype and contracted near their company, industry standard of doing things

i'm surprised they didn't put a heat shield to the cpu and the way they designed the board for the debug headers, not very efficient if you ask me

[cloudasc]

If your going to be installing something in your Fit, like maybe that unit from hong kong or whatever; in your Fit, to the left of the steering wheel on the dash, theres 3 switch plates, right below that is a place for you to slide your hand into. Grab that part of the dash and pull. There is a nice sized compartment area right behind that switch plate/panel. The panel comes off super easy, and easily snaps back into place (after lining up the bottom hook piece). You should check it out

[deevergote]

Nice! I was just looking at that area today, in fact!
That'd be a nice place to locate a power button as well.
