Cyber Gp32

[Tobriand]

I've thought of way to turn the GP32's unpowered USB into a powered one, with just two AA batteries (Can be rechargables, or not, whatever you like), and a few easily obtainable components.

​

Wow... good luck; that' a mod I'd gladly do myself, bar tiny close-range soldering being necessary. Which hopefully it won't be

It won't be, only thing is, that you'll need some skills in making PCBs. You could ofcourse let a company do it. And if you're really good, you could make it a floating one. The circuitry is centered around a MAX641. Which is a step-up converter based on induction. This little device turns 1.2v to 3.6v (abouts, I don't have the datasheet handy, I'll look it up later) into 5v, stable. The external component count is minimal. It's basically an inductor, capacitor, and a transistor. The PCB will therefor be very small. Also, the MAX641 is available in DIL package. (The chip with the large pins, you solder it through the PCB, instead of surface mounted stuff).

wooaah so if you can setup a webserver on it can you surf the web also?

 

[Tristan]

k, I just went and got myself the components (aside from the chip, which is coming by mail), so I should be able to make this thing in a few days time.

​

No, I lack a web browser. But I could use a text browser like lynx

 

[aapje89]

Do you have any files on the gp32 which are downloadeble? LOL

​

Yes: a picture of my secret lab
I will also put tonight the zImage, initrd ans usr.sqf binaries of my gp32.
And some music if you want B)

Would you mind upping your compiled web server somewhere? Saves me the trouble of compiling it myself. And what options did you set under USB Ethernet, just the one driver, or all of the drivers? If you did all of the drivers, mind upping that along with it? Else I'll just build the kernel myself. (Now that I know how, it's quite fun actually )

 

[kknd_cf]

that's cool

 

[toholl]

The GP32 server is online now.

 

[Vimacs]

wow, is that cgi? say me it is cgi. impressing. will move my website over to gp when my network card si supportet

 

[excess]

ikebana sounds great

Very impressive n_n

​

Yes, system info is a simple cgi.
People who want to get the web server stuff can download usr.sqf on the gp32 server.

 

[Steve-O]

So Im surfing a site that your GP32 is hosting?? MAD

​

We need to provide a zImage + filesystem with auto loading of needed usb drivers modules. Now, you need to choose the right usb devices you have to compile them into the kernel.

damn
dont tell me theres no linux web browser?

check my old releases
there is a graphical web browser, but slow
i have to work on a new one , a fast one
anyhelp welcome
[cross compiling problems, browser a little old]

​

Be carefull: max641 can only deliver 50mA. Many USB devices are consuming more than 50mA.
Normally, USB port must support as much as 500mA.

for the ones
not following and not reading all the topics

This is SO COOL soon we will be seeing gp32s with gplinux running all web servers!
Well Done on a great Achievement!
