ShackNet: 7 months, 1 week ago · ViewAnother great meeting on Monday night, My Machine is nearing completion. The mechanics and Electronics are complete, The Teacup firmware is installed and it sort of prints, just adjustment left to go. (Watch out for some more pictures and a brief write up on both my blog and the RepRap builders Blog, when I get to them)
Keith brought along his Prussa Mendel (Same model as the User Groups shared machine) which looks to be coming along great. Keith is onto his electronics the mechanics are looking largely complete.
The Arduino guys who came along brought along some interesting projects, Both Midi to CV and CV to Midi as well as fledgling robotics projects. There was also discusion around a members project tobuild some torque measuring instrumentation. Thanks to John, Chris and everyone else who shared their Arduino Projects and Aspirations with us.
Whilst Keith and my own machines are not realy Arduino projects, i guess these could be comfortably described as such as both use an Arduino Mega as the ontroler for the machinery.
I guess I can’t stress enough how much synergy there is between the Arduino and Reprap groups. With many oportunities for each group to do their own thing as well as contribute making to each persons projects on an as needed/available basis. There is no pressure to go either way and some members whilst having principle interest in one area often come along and do or share somethng completely different with the area.
in summary it was a great evening, looking formward to many more of the same.

ShackNet: 7 months, 3 weeks ago · updated 7 months, 2 weeks ago · ViewGreat, found this group. Heard about Arduino for a few years, only recently got an ’excuse’ to play with it: building a (bipolar) stepper motor controller for telescope drive. My background is a programmer, I knew some electronics from my teenage days.
Here’s the question: I am in the process of acquiring Arduino Uno and the Motor Drive Shield, the one that mentions it can drive two stepper motors.
Is this all I need at the minimum? Later on might needs some buttons and lights/interface but for now can I skip the buttons and just do the commands programmatically?
I’ve not had much experience with motor controllers yet, all I know is that the Arduino’s pins alone don’t provide enough current to drive them, so they require some indirect control (eg. via a transistor). Sounds like the shield you have should take care of that though, so I can only recommend breadboarding something and seeing what happens. You can probably find relevant code through Google

ShackNet: 8 months, 2 weeks ago · updated 8 months ago · ViewJust found this Javascript Arduino Uno interface. Not played with it yet though, will have to wait until I get home http://www.schillmania.com/projects/arduino-js/
Actually, scratch that it also uses Flash, which I don’t allow on my machines
HI, I’ve been looking for something like this as well and so looked at that site and found this mentioned at the top https://github.com/voodootikigod/node-arduino
that is a library for the Node.js javascript webserver for talking to arduino.
Ooo very nice, thanks for this
For my current project I’ve been trying to send JSON back and forth over serial, eg. send ’{”digitalread”:5, ”digitalread”:2, ”analoguewrite”: {”pin”:3, ”value”:512}}’, get back ’{”digitalvalue”:{”pin”:5, ”value”:1}, ”digitalvalue”:{”pin”:2, ”value”:0}}’. This quite a high-level thing to be doing though, which means I’m getting caught up in annoyances like dynamic memory management (we don’t know how long the input will be as we read it in, so we need to keep realloc’ing as our pointers run out of space). I think I’ve been vastly overcomplicating things this way, as the simple const defining and switching done by node-arduino seems to be exactly what I’m after (although I’m working with C++, but it’s simple enough to port). Cheers!

ShackNet: 8 months ago · ViewThought I should announce that I am working on an arduino related project.
http://stretch.deedah.org/waterbear/ is my attempt to make a scratch type graphical programming environment for writing arduino code.It is no where near ready yet but John Mosley reports he can write the blink script in it already.
The project is based on the graphical javascript editor http://waterbearlang.com/
My github for the arduino code is here https://github.com/stretchyboy/waterbear come and join in or just post issues when you find them.
