Yup, my bad :) lsusb it should have been. https://the-sz.com/products/usbid/index.php?v=0x2034&p=0x0105&n= iSoft Silicon, Inc.

Hmmm. The last reply from tech support was "... we don't quite understand what the question you are asking means". Maybe it's absurd, but it makes me wonder if the device is a Trojan. No....that's too clever.... Thanks for humoring me, bob prohaska |

Heat someting up and measure the temperature then touch the solder to it. Raise the temperature 10 deg F at a time . There are charts to tell the melting temperature of the mixes. Most plumbing solder is the 50/50 mix and usually too thick to do much electronic work. |
"Peter W." <peterwieck33@gmail.com>: May 13 03:48AM -0700 Standard plumbing solder is flux-free and 50:50 tin to lead. Then, there is Acid Flux plumbing solder that should not be allowed in the same county as electronic solder. You can determine which is which by cutting off the end. Acid flux solder will have a visible core containing the acid. Typical acid-core solder is 40:60. If the solder in question is either of those *DO NOT* use it for electronics under any circumstances. And if it is vintage tin/lead solder *DO NOT* even use it for plumbing. Peter Wieck Melrose Park, PA |

micky <NONONOmisc07@fmguy.com>: May 12 02:34PM -0400 I renamed the thread and moved it from its original location to the bottom of the list so I wouldn't have to hunt for it so much. >> I was out of the dealership by then, but a simple piece of duct tape >>over the sensor will turn the head lights on constantly when the >>engine is running. That SHOULD turn on the instrument lights. Okay, I tried that and it did turn on the headlights and taillights. BUT the ones in question** didn't go on. Yet up until the last time I drove in the dark, two nights ago, they do go on at night. I will try tonight and see if they still go on at night, but how that could be different from covering the photocell I don't know. FWIW there are actually two photocells but I covered both of them. When I first got the car I asked on ToyotaNation or the other one what the second one was for, and if I got an answer, I forget what it was. Each as a domed plastic cover but one is 1/4" high or more and the other much shorter. I wonder why. **(Most of the other lights are too dim to see during the daytime, but they work fine already.) > e-mail me the schematic / wiring diagram and I'll look at it It will take a bit of time to extract the relevant pages from my 390 page wiring diagram. I'll work on it. > Does it get dimmer when the headlights are on? It should. One thing only does dim and that's the little dot/light on the dash that shows what gear I'm in, and I think that's fair because the other lights are powered directly from 12v. I haven't tested when the headlights go on, but instead, I removed the Panel fuse and ran a jumper from the 12v-when-engine-on to one of the locations the Panel fuse powers**, and when I touch the jumper to that, the dot on the dash goes dimmer and when I remove it it goes back to full daytime brightness. That is reliable. Sometimes!!! when I do touch the jumper that way, the "clock" lights go on, but unreliably and rarely. It will work, then 3 minutes later, it doesn't. And this testing was done at night (they weren't on to begin with I used to think because the panel fuse was out, but later I think they went on without the panel fuse or the hot-wire. I have to do more testing tonight. Prior testing was very confusing, so I hoped you'd just know the answer already, although I suppose it's very unlikely people would complain about something like this and that your service department would try to rewire a car that was working according to the Toyota spec. In the daytime I've never gotten them to go on. Do you think there's any chance, once I have the current operation totally clear and written down, if I wrote to Toyota, they'd tell me why it works that way, or even how to change it? I figure they'd ignore me or tell me to go to a dealer. Most of the lights*** are powered directly from the battery when the Taillight relay is closed, via the Panel fuse, and they don't dim, but normally they only go on at night. I guess going on is the opposite of dimming. **From the 12v that powers the seat heater switch to the light for the seat heater switch, so the wires are only a half inch away from each other. I thought it would be such an elegant fix, except it doens't work for the "clock" lights. It does light up all the other lights below***. ***The speedo cluster, glovebox, the buttons for the radio, heater/ac, seat heater switches, and the gearshift indicator on the center console. And there is a light in the speedometer needle that changes in some way. I think it lights up at night. It's really all very nice except for my one complaint. I would have thought lots of people would complain and by 2006 they would have changed it. I have the digital version of 2006. It's harder to read than on paper, but I checked to the extent I could and haven't found any differences related to this. Maybe that they didn't change it would mean mine is broken, not misdesigned. But I still should be able to fix it. I'll do more testing when it gets dark, which seems to be different from having the photocells covered. >It should >DIM when the headlights are on and be brigher during the day I think. Yes, those gear indicator dots works that way. >Is this an orange/red light? or green? In the speedo cluster, there's a little light for each gear. Park is green. I think the others are different. 2005 Toyota Solara (similar to a Camry) |

I use and like a binocular headband magnifier, very similar to this: https://www.amazon.com/Headband-Magnifying-Magnifier-Head-Mounted-Electronics/dp/B085DRM3WL/ref=sr_1_25?dchild=1&keywords=headband+magnifier&qid=1620838872&sr=8-25 The one I got is a no-name brand that I picked up at a hamfest years ago. All the lenses are plastic. in addition to one fixed lens, there are two additional lenses that fold up out of the way into the visor. My magnifiers are 2x, 4x, 8x. IMHO, using tools with the 2x and 4x on, such as soldering, requires a little getting used to. I find the 8x almost impossible to use with tools and only comes in handy for inspection and for me, can't be worn for long. I found the external loop handy in a few situations. I am not a fan of the built in lighting system as they are not usually well directed to the workpiece and tend not to be very bright. I like that the visor portion folds up and out of the way when not needed. Given these are plastic lenses, the optical quality is not that great and may be a challenge if you wear them for a long period of time. If that is the case, I suggest looking at high grade optical lenses (perhaps glass?). The price will definitely go up. Good luck |
