| Jeff Urban <jurb6006@gmail.com>: Feb 04 12:05PM -0800 I could do that in a half hour. I should show you the regulator board in my bench receiver, it is twice as busted up as that. Send it over and I'll do it for, umm, forty bucks. First, get a scraper. I got a special tool to remove the soldermask. (the green shit)Then bridge most of the bigger foils with solder - only. Then take cyanoacryilate (super glue) and glue it together from the top. Then go to each connection you bridged, of course to made it to the right position, I have had to use a hammer to pound them back together at times, and that is why you do not want the extra thick glue, you want low viscosity. And at each connection reflow the solder blob and embed used solder wick in it. It will lend some strength and therefore longevity. After that get to the smaller connections, any which way. The short distance makes it easy. Some you can do with the cutoffs from the leads of components you have installed in other stuff. (that is REALLY what the tray on your soldering station is for :-) Shit, the one you got is so easy, if you can get to Cleveland bring it over with a case of Bud and I will just do it right in front of you. |
| J-J <none@none.non>: Feb 05 11:32AM -0500 My prior post inquired as to a cheap ink and paper that could be used to test out my recently acquired barograph from an estate sale. After some trial and error and with the group's help, I have managed to get some accurate traces: https://imgur.com/a/kKWKhQh However, at least one issue still remains: the large ink spot you see occurs within an hour of me refilling the tiny ink well on the device arm. Once all that ink "hemorrhages", the trace then proceeds as you see with no more spots. Any idea what could be causing this? Am I adding too much ink each time? One other thing I'd like to ask about is paper. For the chart, I had printed them out on a piece of Georgia Pacific standard 20 lb weight 8.5x11 multipurpose paper and backed it with a couple of strips of packing tape in the event a bleed-through occurred (and good thing I did!). Suggestions for maybe a thicker paper I could try would be welcome, with the idea to increase absorbency and still keep cost low. In a pinch, I've been thinking of just doubling up the sheets I have except the new thickness would not be uniform and glue would decrease absorbency. Thanks in advance. JJ |

I use LPS-1, which is very similar to WD-40. it smells the same, and seems to leave less of the sticky coating on things. I use it mostly for eliminating water on metal parts, and also for preventing rust on tools. I got it in a 20 Oz pump spray bottle, but I believe that spray bottle is no longer sold. My original one had lasted for many refills from a 1 Gal bottle. Jon |
