I just found your channel. I am very interested in your diy lab stuff projescts (incubator, magnetic stirrer ec.t). Are you still sharing videos?

I bought a 40a ac-ac ssr. The brand is jingzheng. I plan on using it for a 3kw 220v floor grinder. It will have thermal pads and mounted to the chassis with a probe and live readout of the temperature. If it fails then i will request a refund and buy a reputable one. My only worry is how it fails? What temp might it fail at? How will i know its failing? And what is the risk of electrocution?

Very usefull video..i want to handle 1200 watts 220 ac but for 18 hours a day straight. You think theese fake relays could handle that? Should i get a heatsink too?

Thanks for explaining in detail all aspects. excellent video.

Great job, I liked your testing the various amps and times. Informative.

been lookin in to this player, but where can i find the refrens regarding what resister to use for specific tracks? i want 5 tracks to be played but cant find information in the documentation what resistor is needed for tracks.

where is the barking dog player?

Better to use contactor than these relay that have false amp rating on labels and until we take it apart we don't have anyway to know the difference.

Very good video. Where can one buy a real good solid state relay? I need one for a robotic project I am working on: a robotic boat: kzbin.info/www/bejne/rpK9fWBsqcSGiZI

Many thanks, had/have a couple of dfplayer boards and assumed both had blown because I couldn't get anything out of them, not even the LED. Video was extremely useful, now to integrate to Alexa!

i went with an 80A for 16A heating element off of mains.

What means “If used appropriately” here? The manufacturer says up to 25A, but the installed TRIAC is only rated up to 12A.

I got one with a heat sink. I set up a computer fan to run when my longmill cnc control board is on and it blows across the ssr and the heat sink. It switches my router and shop vac. Works just fine so far.

Thankyou, 🙏gracias me fue muy util tu video, lo usaré para un radio cibi, para tener la opcion de varios sonidos en un solo chip,saludos de México 🇲🇽 lindo y querido 👍

can this be use on electric tranaformer?

I have also got some of those fake ones from amazon that are clearly knockoffs with a similar branding . I am also a little nervous about using it, it weighs nothing in comparison to the original ones that finally failed.

I bought a couple of these for a little DIY wind turbine dump load circuit, I think it should be fine for that as it's only 12v and won't be running anything over 8amps. Just figured it would be more reliable than a traditional relay. I didn't know they sold fake ones but luckily I ordered much higher tolerance than I need lol

Is it possible to play one song without decreasing the volume?

Does the relay require a load to engage or will it engage before the load is present?

Been thinking about the bolt angle-changing issue with the clamp jaws... your solution is elegant and practical. Awesome work, with regard to both your engineering chops and video production. Hope you can find the time someday to continue this series/theme as outlined in the intro; I'd watch every single one! Keep up the great work.

Great design! I’m printing one out tonight and I will let you know how it works for me.

How does this channel not have 500k+ subs?

How can I change between folders? Thanks so much!

bro take a look at annealing to increase pla heat resistance from 60>170c just heat it to 100c and cool slowly, I'll try it for the clamps and keck clips, silver has the least deformation

Cool !

Very clear explanation, thanks. May i ask what is the best battery and speaker to use if i want to create a tiny mp3 for kids?

good ideas, good video, I´ll for sure print it... abo and like is there ;)

can this play a single file on power up somehow? or does it need a micrcontroller? -- thanks

Outstanding video. Do you think I can find a way to restart a sound quickly. I have a model train and need the Chuff sound. I trigger it by observing drive wheel rotation with iR and two white straps. At low speed the chuff sounds off loud the dies away. But at high speed the device can not react. I wanted a restart to here the Loud start. Retriever loud start at higher speed. Is there a way to rapid restart. Dennis in Virginia on Frankentrain Laboratories.

At 220 v you only breaking one leg? The other side is still energized. Does that not cause harm (110v on one side hot)

did you share the files?

what did you use as base?

Thanks. I was desperately searching for the 'loop' function when using as a standalone. Sorted!

Hey man, are you still planning on finishing this series? Would be interested in your other ideas.

I did a little searching and found very similar brands of SSRs. "FOTEK", "FOETK", "FOFEK", etc. Should I assume that all made in China are fake?

Great video , but can you answer me a question. I am making a sound generator for a model steam train. I only need to play one sound file that goes " Chuffff" and that only lasts about 1 second . I need to trigger it relative to the trains speed so when its running slow it may get triggered every 2 seconds ," Chuff silence Chuff " etc. when it speeds up a little perhaps 1 trigger a second I would get " ChuffChuffChuff" . All good so far but now we get quite fast and the triggers come faster than it takes to play the full sound sample , What I need is for the trigger to cut off the current playback and restart it from the beginning so I get " ChuChuChu or even ChChChCh. Is this possible and if so how ? I dont want it to have to wait untill each chuff has played out its full length . I had planned to use an optical interupt on the trains axle but I worried that if the train stopped with the optical trigger closed it would keep repeating but I suppose using an MCU I could get it to trigger an interrupt on a rising edge so if it stopped when interupting it couldnt play again until the trigger from the optical sensor dropped low and then high again. Sorry for the long post but if you could let me know if and how the sound can be stopped and restarted back at the beginning I would be grateful ..... Don

You are better off using a good quality triac, as these are very poor quality

Thank you for doing this video :)

Thanks for you video. Im trying to do something really simple with this.. So using the example blink project. I want a noise to play every time the led comes on.. However when I add player.play (1) it cases my led to flash like crazy. To put this in context this is for a halloween prop. Every 30 secs the arduino turns on a relay that triggers a motor, at which point I want it to play a scary sound. Thought it would be simple but i'm not getting anywhere fast. Would appreciate your help

But that SSR is not a Fotek, its a F Q TEK, I don't think it complies , try originals and pay the price of quality.

Nice and comprehensive review of the module. What are the 2 USB pins for? A thumb drive?

Great video! Quick question thought. If I use a SSR with an input voltage of 230v, will it instantly switch once the input voltage reach 230v?

Very helpfull i was strugeling with the file system but now it works thx

I own authentic and counterfiet Fotek relays, I will be doing a similar test under a 40A load very soon .

sure glad i watched your video first before using this amazon shit

I have managed to access 20 folders on a MicroSD card with a folder that even has over 300 songs in it, the other folders have various number of songs using Mega 2560 Pro and 20 buttons, each accessing a separate folder, lots of pins, buttons and wires, not using ADKey scheme of 2 pins. Now looking to add Leds to indicate which folder is in use

a Teardown of this relay shows it was only rated for 16A not 40A like it claims

Got one of these babies on my workbench a.t.m., glad to see that they should be totally fine for my 1800 Watt DIY homebrew system. Mine seems to be original though as you can't lift the front cover.

That was on point. Exactly what I needed. Great work, Thank you so much!
