I remember the first CPU equipped car I saw. A 1980ish Datson. The CPU module used a Z80 and all the chips were milspec ceramic. I giggled and wished the owner "Good luck, it won't last till

OK this is as crude as it gets... https://www.hobby-circuits.com/circuits/led-and-light/led-driver/820/mains-operated-led-circuit-schematic For the less tech savvy..... The AC passes through the full

FWIW, wire in a conventional harness weighs a LOT, and connections are common sources of failure. Good connectors cost a lot of money; good connectors to carry significant current cost more. So -

I had lunch with my wife's mechanic cousin and a friend of his who works at the largest GM dealer in central Kentucky. GM uses CAN, LIN and have their own proprietary GMLAN. GMLAN is most often used

The car has a smart charging system, monitors energy out, energy in, to avoid overcharge and, supposedly, increase battery life. However the system is flawed and doesn't totally charge the battery,

Yeah, and it keeps on progressing, at an ever-accelerating pace... No, I didn't know that. Yeah it does. And a lot of the way things are going seems to involve getting rid of as many wires as

Actually, most manufacturers will have a version or another. I believe the idea was started when RV manufacturers started using roling chassis vs custom frames. That was back in late 60s. Or

I remember doing that ages ago, probably around the time I got one of my first scopes. What are you seeing? I know that what I saw wasn't even close to a sine wave... -- Member of the toughest,

Are those only available for GM? We don't have any of those around here... -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of space,

Ditto on the ick. :-) I too avoided a lot of that stuff, and thought about things like the z80 and 6502, which I have bunches of. But having to lash up several chips and burn an EPROM kind of put

Thank you for the fruits of your extensive research.? We have traveled down similar pathways and gotten very very close. I suppose I could have detailed my search when posting but thought e101 might

I think that your AC line signal is a lot cleaner than what you saw. The radiated signals are usually a lot worse. Bertho Sent: 16 December, 2024 9:54 To: [email protected] Subject: Re:

Those in the windshield antennas are really poor performers. Several years ago I was able to get a simple car antenna from my local electronics wholesaler, cost around $6-7 or so. I'd tell people

I looked at those, briefly. IIRC you had to rewire the fixture to remove the ballast from the circuit. Those fixtures I mentioned came with bulbs that were rather mediocre, so I went shopping and

" The Delco part number didn't show up in any net search I attempted, just like with my Toyota part number. "

I am NOT opposed to CAN, LIN, single ended or differential serial, etc. It's just a progression of technology. Did you know there are CAN lightbulbs? Yup. No switches. Switching element is in emitter

Just yesterday my 4 year old grandson and I were playing with my scope. He put his finger on the probe end and I adjusted the sweep and amplitude to get a presentable display. The 60 Hz pickup was

It was more of an example where to find additional information. As you have "12 Delco/GM Auto Radio", it is perfectly understandable that people are going to search for radios that came out of General

Sorry if my response was less then helpful, the "URT, burn in" on the label suggests the radio has network capabilities. I requested year, make, model because it is often possible to track pinout

Where are you looking at the amplitude and phase response? Have you simulated the entire PLL circuit? Andy
