    Raspberry Pi photo booth controller

    Hi MikalV. I'm trying to change the script to print in landscape mode, like you have done here. Can you give me some pointers please as I'm really struggling to get it to work.Many thanks, Steve.

  • Make a High-Altitude Balloon Tracker (Arduino)

    Hi again Ugi,Pretty early on I realised I'd accidentally ordered a 4mhz xtal and changed it for an 8mhz one, so I can rule that out :-)I'm using Arduino IDE 1.0.3, as per your 'ible recommendation. I have the 3 libraries you included in my 'libraries' folder and they are showing as 'contributed' libraries in the IDE. I'm going to send the output of your uBlox test script via PM, because I'm happy to say that it includes my GPS location :-)It looks like the GPS module is working, but as you correctly worked out, isn't interfacing with the sketch correctly. I'll continue to investigate :-)One step closer to getting a balloon in the air.Cheers,Steve

  • Make a High-Altitude Balloon Tracker (Arduino)

    Hi Ugi, Thanks for the continued support, much appreciated. I've been doing a bit of work investigating the problems on my board but I'm no closer to making it work. 1) I ran an I2C scanner on my 328 and got the following :Scanning...I2C device found at address 0x42 !doneI've removed the other I2C devices and can confirm that this is the GPS card reporting.2) The two temperature sensors don't seem to be reporting on the I2C at all.3) There's no change in the output data on the RTTY, even after leaving the board outside for nearly an hour. Is the LED on D13 supposed to illuminate to report GPS lock? I'm sure I read that somewhere :-)I'm at the point now where I'm considering ordering a new 328 and populating a new board, just to rule out and track damage etc. It's frustrating, but hopef...

    *UPDATE* Turns out the sketch hadn't loaded properly, but seems to have now. How long did it normally take to get an initial lock on the GPS? I'm now getting my callsign though but still not getting any GPS coordinates or a valid time. It's either not getting a valid lock or there's no comms with the GPS card.$$DARWIN,0,198:96:72,99.99999,99.99999,0,99,99.99,88.88,9999,7.19,C3p0119*BF38$$DARWIN,0,24:59:58,9999.99999,-8888.88888,0,0,99.99,88.88,9999,9.99,82pFFFF*4201

    Hi Ugi,I now have adequate carrier shift (you're right, had to play around with the voltage divider (I'm guessing the reference voltage has changed in this version of the NTX). I'm getting a readable RTTY TX, but with no useful data:$$-*/,0,24:59:58,9999.99999,-8888.88888,0,0,99.99,88.88,9999,9.99,82pFFFF*60EE$$-*/,0,198:96:72,99.99999,99.99999,0,99,99.99,88.88,9999,7.02,C3p010F*61A6CRCs complete ok but as you can see, I'm not even getting a valid callsign (should be DARWIN). I'm going to go through the code and see if I can work out what's going on, but in the meantime I'd appreciate any input from the master :-)Many thanks,Steve

    Damn it, I'm getting a "stk500_getsync(): not in sync: resp=0x00" as well :-( Going to try it on a linux machine.

    Well, I wait for the compilation to finish then press the reset button. Managed to get the code programmed by choosing a different programmer option. One of my LEDs now flashes away nicely. Tested it with a receiver and am getting what looks like RTTY, but seem to have a frequency shift of over 2kHz! I've checked the value of the resistors and they are what they're supposed to be so a bit of investigation is required.

    Build complete (bar the pressure sensor, which may or may not follow). She's all ready for her sketch, which can wait for another day. This is the best instructable ever ☺

    FYI: I bought a micro SD Card breakout and the pin configuration was different the the tracker board. Saved some weight using a smaller board, gained it all back with the green wiring needed to connect it ?

    Starting the build :-) #veryexcitedSteve

    Hey Ugi. I used DirtyPCB.com. Cheap and cheerful but seems good enough for the job at hand. I actually bought a chip with the 8Mhz bootloader already installed. It was just another job I didn't have to do. This is the one I bought http://www.hobbytronics.co.uk/atmega328-arduino-8m... . Thanks for the pro membership, much appreciated. I have no doubt that I will be in touch with more questions soon :-)Cheers,Steve
