Sorry but you will have to check with someone else. My experience is only with small Li-ion batteries, and it is very limited. Would not want to give out bad info since Li-ion can go bang if done improperly.

Getting it with the discharge protection is the way to go.

I like the idea of adding electro magnets, then something like a 555 to give it a pulsing eye look. (-:

(-:

I would recommend a Plasma Globe before the Plasma disk. The globes are just so much fun, just don't get your cell phone too close to the globe (-: And I think the same thought went through my mind when I first saw the disk (-:

@@retireeelectronics2649 Good idea. I have a couple of plasma balls I bought years ago. One of them is a Gandalf statuette where Gandalf has his hands hovering over a plasma ball. Pretty cool. The plasma disk may be a failed attempt to digitize them. Clearly some things are just better left alone. I don't own a cell phone, never will, but I'll keep it in mind when friends visit.

Not yet, still working on the best solution without mounting anything to walls or ceiling. Have a good day

I am going to have to look for a metal one. The weak spot on this one looks like the nut insert to the plastic. Have a good day

waste only money stupid order this plasma trash, totally not need anywere. maybe if home have 3-4 year childrens have good toy.

You can't do this by using a lot of LEDs, because LEDs are dots, the plasma thing, do lines 😉

It is the same idea as the plasma globes. High voltage and neon or argon or some combination of gases. The light/discharge is between the dots. Will do a closeup video of the display as a short within a day. Gentle teardown later. Have a good day.

The benefits of being retired, can buy toys that never had when being a kid. Guess you don't like the Dunking birds, plasma balls, Lava lamps, either. Have a good day

Just started playing with it and it does react similar to a plasma globe. From a distance it looks like LEDs but it is discharge paths through the gas. I should have included a close up. Have a good day

No specific project yet. Needed to fill order for free shipping, so looked at some possible projects and picked up the specified Mosfets.

Components are much nicer, but I still needed some enclosures (-:

I have a long list of things I want to make, now I have to get at it. Have a good day

I might, but I have some breakout boards for these that I bought a long time ago.

Yes it sure does. I have not followed who merges with whom or who buys up other companies. Newark = Farnell but did they buy up (or merge) MCM at some point. Other than colour the logos look identical

@ not sure if it was a merger or a buy out but I do think it was a merger, MCM was a subsidiary of Newark which is the American company of Farnell.

Some of the old stock would feel at home with my supplies. Still have unopen Active Components ICs in their original packaging +20 years old. Don't believe these go up in value like an unopened comic book (-: Too bad about the desiccant that is shoddy on their part.

Yes, the enclosures will go into a tub, but that was a lot of parts.

Nope. Sadly they just ignore it. One Telus contractor came back 3 times, even after being told to leave and questioned if they could read. It was fun making the sign. Just print the message on white paper then varnish it onto the wood. The paper goes clear when the varnish is applied.

I have done it to many times. Since I use a Samsung A51 sometime it orients 90 off.

Have a good holiday, every day (-:

Cheap is fine since it will probably be outside and high fidelity would be wasted on me. Have a Happy New Year

@@retireeelectronics2649 Happy New Year to you too! And you said what I meant! Cheers

Currently I use my smart phone Samsung A51. The big advantage is easy to zoom and resolution. Problems are it only records for 10 minutes at maximum resolution then the stops. Also since the camera is mounted relatively flat it will switch from landscape to portrait, hence if not paying attention, the resolution comes out wrong. Mostly user error

Thank You, and Have a Happy New Year

Thank You, have a good new year

Agree, need to stock pile a few. Have a happy New Year

Other than the plastic housing, saved the rest. Have a Happy New Year

@@retireeelectronics2649 Good one! All the best in 2025!

Thank You, Guess most people like seeing Oops (-: Have a happy New year

Not sure, but I already have some from AliExpress. Have a Happy New Year

We have two thrift stores in town and both tend to be pricy compared to the one in Ladysmith. The Ladysmith Thrift store is small but i suspect they go through lots of volume. Have a Happy New Year

Yes, but why did it bulge in the first place, is there an issue with the charge circuit. Anyway I need Li-ion batteries for other projects. Have a Happy New Year

Sadly I did crack the display and I was not using much force. I will keep it for experimenting.

So far it has been both, built in internal and SD card for the kid cameras loaded with pictures. Also picked up 3 more advanced cameras and theses all had the SD cards removed. I suspect the parents just think it is a toy then stop thinking about it.

I went back and bought the second one they had at a price of $2.00 with charging cable and manual. Now that I know how I should have taken it apart, might do a couple minute video doing it properly and non-destructively. But I still want the Li-ion batteries which are $$ in Canada due to shipping. As for planned obsolescence that is our battle to keep stuff working and out of the waste disposal system. And I also have an Amstrad PPC512, no blue screen of death that one (-: (-: and it works

Only cost a Cariboo. Plan on reusing the Li-ion batteries and possibly the printer portion. Didn't find any teardown videos on that model and I need the Li-ion batteries which are expensive in Canada. Added later - And as a bonus I deleted all the pictures of the kids that were still in storage.

I splurged and bought the $2 one from the thrift store. Looks in perfect condition and even has a paper roll. Real photography can get very expensive fast (-:

Just got back from the thrift store that had the more expensive one, $2.00 Canadian. The thrift store had a 14 mega pixel Samsung 21X camera for $1 and it works fine. The Ladysmith Health Care Auxiliary Thrift Store usually has fantastic buys. Have a good day

No markings so i will have to test the capacity later. Have a good day

I agree. The cost of a large printer toner cartridge is usually close to the cost of a printer. And for toys, if it uses AA or AAA or worse button cells the cost of running it is ridiculous. Have a good day

They are stretching the term robot but it does cover the part of automated machine that can execute a specific task with little or no human intervention (walking). If it had a remote control it definitely would not be a robot.

😁

Tried something slightly different. Not sure I will do it like that again. Have a good day

It would have been about 30 minutes long at regular speed. Normally I would would have done it at regular speed and chopped it up, but have a minor cold and didn't feel like doing audio. Neat kit and good instructions with it Have a good day

Ok, I do have a 5 lb dry chemical fire extinguisher by the door (-: Hope I never have to use it, very messy.

It needs to oscillate to generate the first step of high voltage through the transformer. On the diode/capacitor side it charges the capacitors on 1/2 the cycle then the other on the other side of the cycle. The end were the bug gets zapped is high voltage DC.

@@retireeelectronics2649 Yes, but I don't see anything in the primary ckt to cause oscilations. What am I missing?

(-: Thanks, it was just not much in the electronics way. Have a happy holiday

(-: Neat thing is the possibilities are endless. The 4mm crystal clear glue sticks probably would make good light pipes. Have a good day

@@retireeelectronics2649 and they can be cut lengthwise, rotate, merge...

Cutting lengthwise might be a bit tricky using a razor, good gloves would be a must. Heating the two halves to merge probably would be messy if trying to keep it as a cylinder. Have a good day

I will be adding to these and I have a large selection of RGB LEDs (4 pin type). Originally these were to go outside as garden lights but still waiting on some little enclosures to arrive. Will probably have another video that will skip the making part and concentrate on creative electronics. Have a good day

Theremin appear very temperamental for construction, definitely don't like stray capacitance in the circuit. Have a good day

@@retireeelectronics2649 I had one, and it was very cool to play! I hope when yours is done, you feel the same!

@@retireeelectronics2649 I.m sorry, that is something you have to live with :)

True the scale is centigrade and the unit of measurement is Celsius. Then there is Fahrenheit where the scale is Fahrenheit and the unit is Fahrenheit, English sucks, sadly it is the only one that I kind of speak and write, both poorly. So far in the comments, several people have indicated it last for a fair amount of time, and since this is a hobby not a business, that is fine with me since this mostly will be used for heat shrink and maybe ripping components off of boards. If this was for a business, you would never see the word AliExpress or eBay 😊😊in my mailbags. In my parts database, I actually tag all parts from Digikey and Newark separate colour since the parts have a pedigree. Have a good day

You are not the only one to cringe. Even if I had picked it up properly first try I suspect it was deep fried. If I try it again I will probably use aluminium foil under it and attach a temperature probe to the surface of the plate. Chemistry heating stir plates are not very accurate, especially cheap ones.

@@retireeelectronics2649 Please don't use aluminum foil ... buy a small fry pan. I have a hot plate that I purchased on amazon for around $70 (search 'Electric Hot Plate 850W') which works very nicely, however your magnetic stirrer looks to be more than adequate for purpose. The temperature is not really that critical, but for sure you shouldn't have it so hot that the solder melts instantly. It should take a minute or more to melt. Setting it at around 250°c will give you lots of time to tweak the parts if they tombstone, while at the same time not catching your PCBs on fire.
