holux 240 charge and use

Hi all,

Is it possible to wire the holux 240 so tat i can charge and use it at the same time??

i'm not a electrical person, can someone tell me how the wire works? especially if the ground connecting to the PSP will cause any problem if i charge and use at the same time?

thanks!

*edit sorry one more question

issit possible to wire the psp remote control to control the directional pad of the psp?

thanks once again!

Not from the remote/headphone port unless you put in place a step-up converter for one. The Holux240 requires +5V from the USB, the controller only has 2.5V available. On top of that, we have no idea what load that 2.5V is designed to bear. So, theoretically it is possible ( with a current limiter added to the step-up )... But again, we'd have to know the load bearing capacity on that little port. I am not sure on the upper USB port... OR, we could separate it out and use the 3.6V from the PSP... Somebody who actually knows this stuff might answer more correctly...

Not without some excessive cutting and soldering... ;-) From software it is possible to assign the remote control keys to certain actions though, I have done it before. However, this could not co-exist with the 236/240 GPS devices, as they are using the same data port...

hi MIB.42,

i think u mistaken my first point. i wanna charge it thru USB not drawin power from PSP. sorry for not mentioning tat. so basically there will be two wire running out from the mini-b, one to psp and the other to a USB for charging

It is possible.
You just need to make a splitter cable.

i was thinking of connecting the remainding unused wires to a USB. i'm only afraid of frying my PSP..

*edit

ok.. now i've found out which wire is the one for chargin my question is do i need to connect 2 grounds? 1 for the PSP data and the other for the charging cable?

Thanks alot!

For the PSP, you need to connect rx and ground which goes to the holux tx and ground.
To charge holux, you need to connect v+ and ground on the holux.
Yes 2 wires go the the same ground.

- Charging what? ( PSP or the Holux )?
- "Thru USB" ( on what the Holux or the PSP or some other external USB device or USB charger )?

Charge the holux.
That was what I understood what the OP wanted.

Ok, so far we are on the same page.
Next question : where does OP want to charge the holux from if "not drawin power from PSP" ?

Charge from a separate power supply.
Holux cannot take power from PSP anyway.
PSP can also be powered from a separate power source so this is not the issue.

I think what the OP wanted is a way to power/charge the holux while it is connect to PSP, thus occcupying the USB port which is also used to power the holux.

What the power souce is is another matter. He/she wanted to know how he/she can connect power to Holux while it is connected to PSP.

That is what I understood.

May be you interpreted it differently?
