My friend and I collaborated to create a very simple open source project that allows you to control the Raspberry Pi's GPIO pins with a simple HTML page, some javascript, and a python script. You don't need to know how to code (the coding is done) and when I first started with my RPi I really wanted...

I'll have to check but I think on my h-bridge I needed to remove ENA and ENB jumpers so that I was individually powering the coils in the stepper. Without removing those jumpers those switches would always be on...let me check.

MorePiPlease

Ok so I found an unacceptable amount of help returned from the google query "raspberry pi easy stepper python" Therefore I bestow unto you (on behalf of rowboboat.com) the following python which will turn your stepper left and right very simply. :o :D :idea: 8-) #Step 0: Preamble #------------------...

It is working! I had to find the following wiring layout on the internet and perhaps this will help someone else.

I am using the raspberry pi b+ and these two components along with a bench-top 12v power supply. stepper motor part no: 42hs4013a4 L298N SainSmart http://www.sainsmart.com/sainsmart-l298n-dual-h-bridge-stepper-motor-driver-controller-board-module-for-arduino-robot.html I have taken the jumpers off t...

Good morning everyone, Im in need of some help, I am trying to find some documentation on the SainSmart l298n Dual H Bridge. I am unsure of where the VCC goes to on the Raspberry Pi, I have never used this type of bridge before and when searching for instructions ... they are short in coming Here i...

I am about to begin my quest to run a stepper motor with an h-bridge and I am using the info from this thread to do so...thank you for sharing and creating this information. I read the previous thread and know that you started without knowing how to do this and researched it in order to create this ...

MorePiPlease

never mind going to rshack tomorrow grabbing ULN2003 and another power supply...i want isolation.

MorePiPlease

Man I wish there was one thread for this module as it is all over the internet but not one simple howto is written with diagrams for the raspberry pi. Here is what i am thinking of doing... http://dl.dropbox.com/u/93105539/RPi_to_SainSmart4RelayModule.jpg I would obviously remove the jumper but i do...

MorePiPlease

Ok I edited the original photo from this threads opening post and so here is what I am considering: http://dl.dropbox.com/u/93105539/RPi_to_SainSmart4RelayModule.jpg I have read more than just this thread and I understand the risks...will this work? I actually will only be using one of the relays fo...

MorePiPlease

That aside. I just had a look at the schematics. If I had this device I would have connected it up as the OP indicated in the first post with one change. On the jumper VCC/JD-VCC I'd connect 5V to JD-VCC rather than VCC. I'd listen for the relays clicking before connecting to A/C though (and being ...

This is great! I am using LAMP to teach my students database this semester and am going to do an open source thermostat program as our final project. I started searching around and I found this HotPi project started by David. Will keep you updated on our progress.

Well I have the web streaming running with the defualt 352x288 resolution seems very stable...I'll tweak it and see what happens.

MorePiPlease

currently running @ 640x480 but only 2 FPS (defuault motion.conf setting)...I'll pump it up tonight.

MorePiPlease

Motion is running great now. I used to run servers that would only be bounced every six months so it is hard to say that 20 hours of uptime equates to rock solid but the performance is good and it seems solid now. I left it running today when I left this morning for work and will give you some perfo...

MorePiPlease

Performance of Motion is noticeably faster and appears stable (or at least is not crashing randomly after 3-15 seconds as it was)...I have had it running for 5 minutes which was unthinkable last night. Going to kill it and tweak it cause that is how we roll.

Removed the USB drive, set motion.conf to put put only snapshots to a folder on my desktop....let's see how it goes.

MorePiPlease

Honestly I did so much troubleshooting in last night's session I need to go back and look at what worked and what did not. Tonight I will try no usb thumb drive and just snapshots (no video) writing to the SD card. If that works, I'll add video back into the equation. in this google tech talk the US...

This thread is quite long and I have read most of it. I am glad you all were hacking your RPi last night, just as i was. I had an extreme bit of difficulty with my RPi using Motion and a QC usb webcam. I thought for hours it was my configuration. Finally it dawned on me that it was a performance iss...
