Re: [Emc-users] OT: PDA's and machine control

From my brief look at it, it looks ideal (34 GPIO pins, yea). I would be
mounting it, or the display at least, at the focal point of a lens of
the same size as the display area. This will project the image up to a
clear glass panel, tilted 45 degrees to the telescope view. The user
looks straight through the glass to see stars and also the reflection of
the screen.

Wow, Kirk, as a guy who never got past grinding a mediocre 6inch
reflector 50 years ago but still loves skywatching, I love your
application. It looks like a winner.
Were I in your shoes, I'd pilot this application by running the software
on a vanilla low-power motherboard (of which we've had several
discussions on this list) and lashing up a display out of whatever was
at hand. That way, I'd be sure I could run Kstars and anything else I
thought of along the way, I'd have the parallel port, and I could play
with display technologies to find what works best. Among other things,
this would allow me to keep some mass off the telescope tube.
If I decided to start with a PDA, I'd consider running a vnc client on
it (just like I'm trying to do on my Insignia Infocast) so I could do
the serious processing elsewhere. This was the approach I took some
years ago when I was using HP/Compaq iPAQs to prototype first-responder
applications at work.
Good hunting and please let us know how it works out!
Regards,
Kent

So, I'm considering something with Linux, a small display (monochrome okay, will change backlight to red) and TTL I/O, (and sub $50, used on eBay). You have to consider the needed computing power if you want to load something extra on, like Kstars. Aptitude says Kstars needs 197MB of space to install, and having a cpu 200MHz will improve how responsive it is, I'm sure. I'd recommend looking at old(ish) thin clients on ebay - in particular, there are ones made by Neoware, some with NatSemi Geode GX1 cpus, and some with Via C3 or C7, you can easily remove the NTe or XPe installed on the DOM (disk-on-module), and install a lightweight linux. I'm currently playing with a few of these, building custom OpenWRT images. I have one running at the house right now as a cellular modem router :) Look around, you can find something with parallel port, serial, ps/2, usb1.1, video, ethernet and audio, ram that can be upgraded, a usable-sized DOM (which can be upgraded by a compact flash - ide adapter), for $30 including shipping. -- Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

It can run debian for example and has a native usb host interface for external usb devices. When the case is opened there are also a few gpio pins and an I2C/SPI Interface available. I never hacked my own one to add more hardware but there are a few projects which did this with help of a few gpio pins for this device. The hardware and software are completely opensource and the schematics are available in the internet at [1] for downloading. Maybe you can find out in the schematics if there are enough interfaces for your purpose.
