Re: 555 timer missing pin

Schematics like Art can be represented in a range of ways that are graphically quite different. Omission of unused pins on a device is common but can lead to confusion when thinking about construction. One style mimics the physical chip package and arrangement on a PCB and another style is more simp...

Re: off grid solar project

Thanks for the info, the link had some general perspective advice that was useful. I'm still collecting components, installation won't be for a month or two since I can only work on this during weekends (until daylight savings time at least when there is enough time after work). I've only just compl...

off grid solar project

I'm upgrading a shed to be a detached office thanks to working from home during the pandemic. One feature I would like to install is a small solar system mainly for lighting but maybe also for small AC loads depending on how much capacity I have left over after the lighting is selected and a run tim...

Re: Computer Photo Organizers

I'm not familiar with the photo sticks but it seems like one would need the power of a large computer on the cloud to do the kind of image recognition and sorting you crave. I think some cloud storage like facebook might do this. I expect its coming to PC but still will need a decent processor to do...

Re: HotSpot question

there are some Xfinity hotspots that are installed in public areas but the majority of hotspots are second channel WiFi from home and business account routers wherever there happens to be one. I was commenting based on the second case not knowing where your hotspot was emitted from. Rant on Cable pr...

Re: HotSpot question

My android phone in the Settings - About - Sim Card Status page, I can see the measured signal strength. (I used search in my settings to find it fast) He can look at that and log the strength over several days at fixed time intervals to figure out if signal strength is fading at any time of the day...

Re: Hacking an old TomTom

Any maps I have are over a dozen years old. Most people regard this as obsoleted by smart phones although they are useful when in poor reception areas and off road (though you can download offline maps on your phone too. If you want any files, I can send a link in PM but since I will take the materi...

Re: Help finding a replacement led display

I suspect Adafruit is not making those modules for the same reason you can't find the LED displays. There are other lower power displays now, you may need to substitute unless you can find some on Alibaba or something.

Re: Hacking an old TomTom

Not a TomTom but I did have fun way back then with a generic Windows CE device (V7 I think) and was able to jail break it and upload tomtom software to it. Its been over a decade, I'd have to take some time to review old folders on how I did it. It should be Windows CE OS and you should be able to l...

Re: Realistic specs

WD40 is a mixture of solvent and oil. while the solvent might work, it will leave lots of oil behind way worse than the lubricated contact cleaner. Isopropyl alcohol, the 90% stuff from the hardware store, not 70% rubbing alcohol which also may contain oil. Whatever you do, don't ultrasonic or the m...

Re: WAT IZZ IT?

sounds like the parts in the bag can make some kind of tesla coil or just a HV supply but how it interacts with the glass ball and whether that is some kind of insulator that acts like a handle or just a gee wiz toy that sparkles as you guessed, I can't say without a photo. Details about constructio...

Re: Yet another battery charger question...lol

Its not unreasonable that the charger you have has a resistor divider that sets a threshold for a comparator you can adjust but without a schematic or even a photo, its pure speculation. If you keep looking, I'm sure you can find a 120V version, sometimes the graphics in ebay ads don't match the vol...
