content: Thanks, I enjoyed watching that.Those tiny CRT tubes you show at the end, are quite amazing.I was very impressed with the build quality of the camera. Which is no real surprise, given that it is a professional, broadcast camera, and might be expected to take the odd knock, here and there, since it is portable.I'm surprised that there was so much electronics, squeezed into that device. I guess it all has its purposes, and they wanted the picture quality, to be of the highest standard. Since it is not a mass consumer item, it would not be worth getting custom parts made up (except some things which were best made as custom parts, anyway, such as the switch labeling etc), such as custom ICs, as they would never get the development money back.Which is probably part of the reason. But there may have been some custom parts.Electronics was not that compact, then either, especially before surface mount technology and overuse of microcontrollers, further made things much, much smaller.I could see a number of tiles in it. I wonder why it has got those ?Maybe it is because they can have custom resistor values and maybe other stuff, built into it. Or could it be to save space, as it may be more compact, until surface mount technology comes out. It may even have surface mount parts on it, hence saving space.The tiles could also be different, for different countries TV standards, if applicable. I'm not sure if that changes the camera, but the frame rates (50 Hz vs 60 Hz) may change.

So avoiding high density SMD parts would have been a selling point i would imagine. Makes the servicing much easier and cheaper.

content: Quote from: dexters_lab on August 02, 2016, 06:50:04 amYes designing them for serviceability, and avoiding SMD parts (even if available) makes a lot of sense.Proper SMD reworking techniques and equipment, was probably in its infancy then as well.I guess that if they did use SMD in something like that (in that older time zone), they could use tiles. Which would then mean that the SMD parts are potted/epoxy or similarly sealed for life, and can just be changed as a complete unit. So no worries about SMD reworking skills/equipment, as the tiles can have standard SIL pins, coming out of them. Hence the SMD work can be done in a specialist factory, with the right skills and equipment, then creating a small throwaway, easily replaced unit.

Later saw the white tiled floor with black splotches. Looked at my lap and tons of ink stained my shirt, shorts, hands and knees.Spent the next 30min cleaning up the mess and put the opened printer in running tap water in the garden to flush out all the ink. Dried it up and it worked without fixing anything else.

content: have you tried contacting Sick about how to reset a password? I would imagine their support teams have to deal with lost / forgotten passwords quite often.i wonder if the main rom code would be contained within the PSD302 device as it has a much larger memory size and has a sticker with a date on it. That might indicate the user definable parameters & password could be stored in the smaller X28HC64 device.could take some effort to read out the data though

timestamp: July 18, 2016, 09:02:18 pm
content: These are not the passwords you are looking for. Not settable in the scanner or recoverable. These are for SICK staff (well depends on the level of authorization, lower privileged ones might be for support) to enable more settings/tuning options when configuring and calibrating the device. Also, thanks to that, some random guy on the factory floor cannot reconfigure the scanner. I cannot say much more, but maybe you'll be able to recover them by disassembling/reverse engineering the software.The lowest privileged one, at least for LMS200 (PLS might be different because it is a completely different design) is described here, should be good enough for basic (safe) settings:http://www.pages.drexel.edu/~kws23/tutorials/sick/sick.htmlHigher privileged passwords are of not much use anyway and messing up the internal settings is highly likely.

Just had a third stage which allowed you to rotate some of the slides in the ring as you wanted, so you could rotate the image. Did have a series of microswitches running on the outside of the gobo rings to sense a home position and to stop when it had reached each pattern. Light was a 8VAC lamp in a nice little SRBP holder.

I also bought some Martin Roboscan 918's which have rotating gobos, prisms, frost filters and all kinds of nice effects. There's a striking difference though in that Clay Paky lights are clearly designed for maintenance and repair, even with non-standard parts, the Martin lights are not even that well designed for repair.

They added DMX with a software patch, but could not fix the polarity.Regards, Dan.

content: Don't go too far in your teardown, as you may ruin the optical setup. Each laser scanner is calibrated in the factory to adjust for mechanical position of optical components, the exact length of the delay line etc. IR leds and sensors are to detect dust on the cover.Also, this is PLS series (yellow), a safety device, not very long range or accurate, but manufactured with all the life critical standards in mind and is used to, for example, turn off big industrial robot when you step in its operating area.If you need measurement accuracy rather than safety there are blue series lasers, LMS200, LMS500 and new cool small TIM5xx.

It should not be necessary to put it in with the notch in the correct position, after inserting the ring the wheel motor should make a few fast turns so it locks.The correction tape is of the type Lift-Off, it is just sticky tape used with carbon printing tape, it lifts the carbon off the paper (or it should if it was still fresh, I guess it is not sticky anymore).The cover-up tape with the white stuff is used when you have a nylon (inked) print ribbon, this can not be lifted off the paper and has to be covered.The red piece of plastic at the rear of the hammer is to indicate the position of the carriage, you can see a scale for the 3 pitches on the clear plastic of the cover.

content: It reminds me of something said to me when I was a VERY junior engineer and the ink on my degree was still wet. "Always check that a circuit is not live before you start working on it, then check again. Cooking in your own juices is a bad way to die".I wonder if the ballistics gel got the information that they wanted? I would be tempted to mix various items in with the gel in an effort to improve conductivity but then there might be problems with it setting.

content: Not bad at all. The advertising is a bit annoying - but that's an understandable concession.Just tried an 'impossible' parallel resistor calculation - and while it DID object in a controlled way, there were a couple of things I was not keen on...1. The 'calculated' field still held the previous figure. It should be cleared, otherwise there is the risk of an incorrect figure being used.2. The notification of the 'impossible' status appears in a demure little text box at the top of the screen - far removed from the calculation area. Such a notification needs to be far more obvious AND right at the area being looked at. Perhaps add a thick red border around the box of the result that cannot be calculated.

Because of some timing constraints and my inexperience it is hard to add something more to the synthesis because even small change will break the functionality.I'm not exactly sure whether this LVDS series will continue, but I have also other electronic videos on my channel.Suggestions, feedback and subscribing helps.

60W Electronic Dummy Load Mod 20mA to 999mA - Page 1
Forum section: electronics / general

author: voltlog
author_rank: Regular Contributor
timestamp: April 02, 2016, 02:04:50 pm
content: A viewer asked on youtube if this electronic dummy load could be hacked to work lower than 0.2A. In a previous video I explained the limitation is probably given by the low value 10mohm shunt resistor. The dummy load is rated up to 10A so it has to use a small value shunt but that 10 mohm resistor cannot generate a high enough voltage drop for currents less than 0.2A so that is probably why the load is software limited to 0.2A minimum. After reading the comment on youtube I immediately thought about experimented with a 0.1 ohm resistor and it works perfectly, the whole range is shifted by an order of magnitude and I can now adjust between 20mA and 999mA instead of the original 0.2A to 9.99A. Now I can test even low current power supplies or batteries. Enjoy the video and let me know what you think.

author: voltlog
author_rank: Regular Contributor
timestamp: April 02, 2016, 04:15:26 pm
content: That is indeed a good point, the shunt resistor would be better mounter on the other side touching directly the high current path. In my case I am relying on the big plate through holes, filled with solder for the high current path which in this case is 1A maximum and will work just fine but if a higher current was used I would have to solder it on the back side as suggested.Thank you.

I have seen the fakes where the same board is used, but the USB sockets are simply connected in parallel along the line, with the black blob, and the 2 small mystery SMD caps and the fake 12MHZ crystal flapping around in the breeze, simply being there to fool you. Looking at the top of the ultra thin board you see there is no die attach point, and the USB lines simply are going through the blob and splitting there under the blob, with the crystal connections stopping right at the edge of the blob.I just cut the PCB traces after the first outlet, and use it as a simple USB extension cable, as all I wanted it for was as an extension for a short lead behind the case in any case, so it did the job for that low current low rate job. Mouse works fine over it, though I have my doubts if it would actually support full speed use, as the thin cabling is totally lacking in both impedance matching, twisted pair construction or shielding.
