Repair / Re: Power Over Ethernet camera repair

These were all indoor. The Axis 206 was a high end IP camera in its day, IIRC they were over $300 each in 2005.

'robots' replacing humans isn't a maybe proposition, its happening everywhere on a large scale. People are too smart and too expensive to have them do 99% of what is done in factories. The emergence of deep learning and associated technologies has the potential to soon eliminate the expensive programming staff and make teaching 'robots' as easy as doing the thing yourself a few times, poof, they will have learned how to do it.

Humans aren't kept around for sentimental reasons, they have been utilized solely because until recently they were the only and then the cheapest way to do things. But those days are almost over. It is happening very quickly.

I don't really think that robots will replace humans in factories, I think it's more like a cooperation between machines and humans rather than a fully automated factory made of robots, but to implement that kind of system will take 50 years or so... Mostly Because it's true that technology change quite rapidly, but not many factories want to make an investment on that sense.

Moreover, in automation if you want to change something, things can be quite challenging. Not to mention you need someone reprogramming the software.

Robots are made to make the hard work, but their comprehension about "how the work is done" is rather limited, thus, in order to weld or other peculiar work, you need a good welder, period.
And this does apply to a lot of other works in a production environment in both heavy and light industry.

In my modest opinion the production world is heading in one direction : 0 waste.

I can see why people really want to believe this. But its not true. Automation is oftentimes much better at jobs than humans because of our large brains. We let our minds drift away and get off track (like I am doing right now)

Just like the camshaft or ignition timing in a gasoline engine, the timing is only ideal for one specific set of circumstances, for all others it's a compromise.

Repair / Re: How do you measure the power going into an AC induction motor?
« Last post by IanB on Today at 11:45:15 am »
Something doesn't seem right. If it is truly an AC induction motor running approximately at a fixed speed, then the current with no load should be far less than the current when driving the fan. Regardless of power factor, the current should be less with no load.

As to your main question, the best option would be to use a device like a Kill-A-Watt. That will tell you voltage, current, power and power factor, accurately and without fuss. A DMM is not the right tool for this job.

Dodgy Technology / Re: Stupid Indian noobie youtubers.

I worry that people are becoming too conditioned to things being safe, relying on protective measures and warnings on everything to warn against any possible hazard. It's more useful IMO to hammer in at an early age that certain things are dangerous and how to recognize risks and reduce the chance of becoming a statistic. Electricity can electrocute you, water can drown you. Sharp objects can cut you, power tools can slice bits of you off, hot objects can burn you, falling  from high places can kill you. Learning early on how to recognize and avoid dangers on a larger scale is better than trying to shield everybody from everything on a case by case basis.

Test Equipment / Re: Mid-level bench multimeter
« Last post by Neomys Sapiens on Today at 11:43:31 am »
With those meters, one can assume that they perform according to their specs.

so it is in the details, such as:
- rate selection (preferably not the same function as resolution)
- Filtering in HW or Sw or both or none?
- diode test voltage range
- AC only vs. AC+DC
- support for accessories, like probe factors

and of course, your display preference and the size/weight.

Do you refer to the HMC8012 from Hameg or the module HM8012?
The latter is quite below the other instruments in all aspects, while the HMC8012 might be the most advanced one.
Personally, I'd say the HMC or the Keithley.

80186 featured in desktop machines from RM here in the UK. Probably cheaper :)

Nice collection BTW. Worst CPU ever but worth collecting.

There was a strange time of 1983-1985 when companies piled into the desktop PC market and practically every entry made the same two mistakes. First they tried to compete at close to IBM price levels, when beige box XT clones had just started showing up from Taiwan at half price. Second they would dick around and make it not quite binary compatible with IBM, like  designing in a 186, again the beige box units were full exact  clones.

Technix really needs to get a hold of one or 2 NEC v20's. Socket compatible with an 8088, slightly faster with string moves and includes the capability to run 8080a code natively, so you could run a copy of CPM-80 and CPM-80 applications at full speed. And then switch back to MS-dos.

Beginners / Re: I can’t compensate my probe
« Last post by chris_leyson on Today at 11:42:47 am »
The P6137 is designed for the 2400 series and the P6137 manual states 12pF to 18pF compensation range. Input capacitance for the 2465B is 15pF +/- 2pF so the probe compensation range is spot on for the scope. You may have to take the cover off the "compensation block" at the scope and adjust the LF compensation trimmer. The TEK documentation, link below, leaves a lot to be desired though.

RF, Microwave, HAM Radio / Re: ICOM Rc-28
« Last post by cncjerry on Today at 11:39:03 am »
I found the data structure where the VID and PID are coded and I am going to recompile and test.  There could be some secret sauce I'm missing but one step at a time.  Worst case is I hook up the logic analyzer and decode the stream.

The RC-28 adds a ton of function to both the 7610 as well as the RS-BA1 software.  Having a low cost version is clearly worth the effort.
