    DIY Auto Headlights with keyless entry

    This is a good suggestion and one I briefly stumbled across in my research, but I was hoping to do this with parts I had readily on hand, and I don't think I had the right diode. I may check again to see if I have any and if not, get some on order. I suspect that the weird issues I was seeing...

    DIY Auto Headlights with keyless entry

    Alright so it's been over a week with the hardware installed. The key takeaway is that it works but is quirky. Below are some of the things I noticed that can be fixed, and some that are outright weird. Unlocking the car from the interior unlock button on the door is the equivalent to...

    DIY Auto Headlights with keyless entry

    This is smart. I've done it before but didn't think to do it here. Might give it a try soon. My trunk light doesn't work so I'm going to have to check on that too at some point.

    2003 Protege5 FSZE Engine swap issues and options?

    Cool cool. Considering your JDM replacement engine stories, I was thinking you were the right person to answer this question.

    DIY Auto Headlights with keyless entry

    It works! This is a lame update but I did get the system working...mostly. I'll add more later. I was able to fix the immediate relocking issue by changing the values of the voltage divider resistors I was using to 10k and 20k instead of 1k and 2.2k. The logic behind this is that the higher...

    DIY Auto Headlights with keyless entry

    Slow progress... Progress has been slow but I haven't given up! After I made the last post, I quickly realized that my graph was incorrectly labeled...not that it matters much. The data was taken without the module plugged into the car and I was getting some really weird measurements that...

    Are you doing a rear or front bearing?

    Protege5 Side Mirrors from Mazda3?

    This is an appealing proposition. I just spent a lot of time trying to replace a mirror and it seems like a lot of P5 mirrors are brittle, old, and expensive. My initial thought is that a Mazda 3 mirror wouldn't fit, but I have nothing to go off on that, and if you saw something on it being...

    How difficult is a Wheel Bearing and Control Arm replacement?

    Rear wheel bearings are cake because you can just replace the hub. Haven't done front bearings but I imagine they're a lot harder. PCB seems to have given good advice above so I'll leave it at that. As for control arms, I did them for the first time on my P5 and have now done them a second...

    DIY Auto Headlights with keyless entry

    Progress! I soldered some test points to the connector's solder pads on the back of the keyless entry module . These wires will probably get snipped to the right length later and directly soldered to the Arduino. I soldered on wires for just the pins I needed at the moment. This included...

    DIY Auto Headlights with keyless entry

    Antenna modifications I'm certainly not an antenna expert, and as I look more into how antennas work, I am reminded of that even more. I realize that modifying this antenna might not be the best idea, and there definitely could be more to the seemingly arbitrary way it's designed that I might...
