No. But I wasn’t doing anything particularly complex, just a LAMP stack server for some game forums. Think I had a Dell desktop. Was a dishwasher at the time.

Took a few days fumbling through tutorials but I eventually got it up and running. Repeated that a few times over the years, once to host a blog, stuff like that.

Would like to get into it again but all I have now is a tablet.

Ah, a fellow controls guy out in the wild.

Probably Voltron, though I didn’t know what anime was at that time. Probably saw some Sailor Moon. Nickelodeon used to show some random stuff.

As a teen my first deliberate move towards finding more anime to watch was after seeing Ninja Scroll and Neo-Tokyo on VHS. Both of those blew my mind and I knew then there were much better shows out there than what was being produced in the States.

That’s great!

Going outside

Sorry for blowing up your thread but as for repairing it, might not hurt to draw up a schematic based on the board and try to ascertain exactly what the resistor is doing and why it is in the range it is in.

If it were me, I would separate out the pressure signaling system and see on which side the anomaly occurs. If you provide a solid signal and it still oscillates, the problem is probably in the main board. On the other hand, if a solid signal produces a one-off effect, the issue is in the pressure sensing module. Something is causing it to oscillate.

Personally? No. Mainly because while I have had to ID and work with resistors at work a few times, I am a hobbyist, and I haven’t worked on anything older than the 90s.

Again, from an amateur perspective, the color codes we’re familiar with wasn’t globally adopted until 1969. We don’t know where or when this resistor was made. It even looks different from the others. Considering that the reading is very close to one of the interpretations you have from the coding, I would guess it’s non standard but close and probably within the intended spec. Again, grain of salt, etc.

But check this out:

Color Code Exceptions

The color coded resistors are inserted in circuit boards, and the PCB assembly manufacturing is finished by thru-hole pin soldering.

Reliability band: 

Resistors that are produced according to military specifications, sometimes include an extra band to indicate reliability. This is specified in failure rate (%) per 1000 hours of service. This is rarely used in commercial electronics. Most often the reliability band can be found on four band resistors. More information about the reliability can be found in the US military handbook MIL-HDBK-199.

Single black band or zero-ohm resistor:

A resistor with a single black band is called a zero-ohm resistor. Principally, it is used as a wire link that functions to connect traces on a printed circuit board (PCB). Using the resistor package allows the same automated pick-and-place machines to place the components on a circuit board.

5 band resistor with a 4th band of gold or silver: 

Five band resistors with a fourth band of gold or silver form an exception and are used on specialized and older resistors. The first two bands represent the significant digits, the 3rd is the multiplication factor, the 4th is the tolerance, and the 5th is the temperature coefficient (ppm/˚C).

Deviating colors: 

For high voltage resistors, the colors gold and silver are often replaced with yellow and gray. This is to prevent having metal particles in the coating.

If I had to guess, 151 with silver being the tolerance range and blue the temperature coefficient.

I don’t know if I can handle another one
