Sorry for the long absence. Life gets in the way of what I want to do way too often lately. I finished the revision to the intermittent wiper unit. I added a metal-foil resistor and polyester capacitor to each relay. This RC snubber prevents arcing that could occur whenever the relay opens. The uC side has a resettable fuse, reverse-polarity protection, and a TVS diode for transient voltage protection. The voltage regulator is designed for much larger loads and uses the ground plane as a heatsink so it produces virtually no heat. The 12V side has an 8A fuse and the wiper motor traces were increased to handle a sustained 8A with very little (10ºC) heat rise. According to Coolerman, the wiper motor can pull up to 3.5A under heavy load with a stall current maybe twice that. If you see over 8A, you have a real problem somewhere. I need to take time to modify some of the uC firmware. It works fine, but it takes more of the memory space than I want it to.
There is a two-pin header that I use for testing. With a USB to TTL cable you can see what the uC is doing. The screenshot below shows the ignition switched on, and the wiper switch pulled to slow and quickly back to off twice ~3 seconds apart. This put the wipers in intermittent mode sweeping with a ~3-second interval.
I just assembled one, tested it, and will mail it to Coolerman next week. When I get his feedback, I’ll press ahead with any necessary changes and a final version. I'll try not to disappear again...
Family first mate! Then some cruiser time!I'm just swamped with work and exasperated with my two teenagers in high school. Haven't had much brain power left by the end of the day but I'll get back on it soon.
Having had 7 of my own, I certainly understand. I patiently await. - MarcI'm just swamped with work and exasperated with my two teenagers in high school. Haven't had much brain power left by the end of the day but I'll get back on it soon.
I would love to try out a unit. For a wiper switch, I simulated the FJ40 OEM switch wiring into a DPDT Contura switch using Coolerman's wiring diagrams to operate my triple wiper setup. It was difficult, but I finally got it. It still has the hi/off/low position, and my washer is a momentary off/on right next to it, so it would be awesome to have that operate the wipers for a few seconds like you mentioned previously.
So, I don't even need the plugs on the unit, I just need a few inches of wire coming out of each side. Let me know if I'm able to get a naked setup like that.
Thanks!
