    Back up camera?

    SparkMoore, Good job! I'm curious as to why you didn't use the camera and routing technique earlier in this same thread, starting around page six: http://www.mychevysparkev.com/forum/viewtopic.php?p=12111#p12111

    Yes, it is definitely NTSC composite video.

    My longest roadtrip 1200 miles

    Reading some of the responses it looks like people are not using http://www.plugshare.com You really should use this. Not only is it free, it shows ALL power vendors including private homes willing to charge. The link is for planning your trip beforehand. There is an App for when your on the...

    Back up camera?

    Wow, sorry to hear that. I sent him a substantial pm January 27 and never heard back anything. Seemed out of character as he was always very courteous. Jeez, we were just starting to have some fun.

    Back up camera?

    The same only different. :? Nothing's ever simple these days. solder's Spark DD code ran on a Teensy using FlexCAN library and got data off the 2 wire high speed CAN bus. I ported it to run on an Arduino due running due_Can library. because thats what I had. This task gets data from the...

    Back up camera?

    Ya, thats the next step I haven't figured out, yet. You have to be a pretty handy nerd to do this as it stands. If you like reading schematics, programing Arduino's, figuring out and modifying other peoples software, soldering .05inch pitch parts, using an oscilloscope, splicing into perfectly...

    Back up camera?

    Finally got my little backup camera project finished ! I'd like to thank all on this thread for help and inspiration, especially solder. I learned a lot about how the CAN bus works. Here it is in operation: https://youtu.be/gQagP5NV2ZY The final and most difficult part was faking the head...

    Work on "SparkDD" status

    Finally got my Arduino due to do some CAN. Here's some output from solder's code on a 2014 Spark: Cell 1: 3.32 Cell 2: 3.32 Cell 3: 3.32 Cell 4: 3.32 Cell 5: 3.32 Cell 6: 3.32 Cell 7: 3.32 Cell 8: 3.32 Cell 9: 3.32 Cell 10: 3.32 Cell 11: 3.32 Cell 12: 3.32 Cell 13: 3.32...

    Work on "SparkDD" status

    solder Think I may have found an error toward the end of the voltages. 481 define_dpid(0x7e7, 0xfe, 0x0x424a, 0x424b, 0x424c);//was define_dpid(0x7e7, 0xfe, 0x423b, 0x423c, 0x423d); 482 define_dpid(0x7e7, 0xfd, 424d, 0x424e, 0x424f);//was define_dpid(0x7e7, 0xfd, 0x423e, 0x423f, 0x4240); 483...

    Regenerative braking in reverse down a steep driveway

    Yaa!, somebody finally tried it. I feel much safer using this technique than the non-linear brakes backing down steep hills. The great rearward visibility :? doesn't help.. Don't do that, at least the stall part. As the User Manual p.9-21 notes: "... holding the vehicle in one place on a...

    Regenerative braking in reverse down a steep driveway

    That creep is the fairly awesome control system faking you out. It makes creep because that what drivers are used to. However, as soon as you put on the brake enough + fraction of a second the torque is shut off. When you lift your foot off the brake the control system turns it back on. You...

    Regenerative braking in reverse down a steep driveway

    I don't think what I described is a software bug and I don't think it hurts anything. The 'transmission' is in name only. The motor rotor is always connected to the output shafts thru the planetary gear reducer/differential, no mater the gear, including neutral. The only conventional...

    Regenerative braking in reverse down a steep driveway

    Restating using words for the actual direction and letters fro the gear position: Regarding reverse (and R). Here's something fun to try. Put in R, grab your balls :o and head down that steep hill in reverse and without putting on the brakes slide the shifter into D. Whalla, regenerative...

    Regenerative braking in reverse down a steep driveway

    JackHickey, Boy I love this Spark! What a fun toy. Regarding reverse. Here's something fun to try. Put in reverse, grab your balls :o and head down that steep hill and without putting on the brakes slide the shifter into forward. Whalla, regenerative breaking in reverse ! Nice and...
