Hey Steve, Enjoy everything you do to help us that don't have the knowledge. Thanks
My pleasure! I'm glad I can help.
This kind of stuff is what Makes electronics fun for those of us that aren’t engineers.
I'm glad it was helpful and thanks for watching!
I was thinking of buying that same black box on Amazon and hacking it like you did. You proved it can be done...Thanks very much!!!
This video shows a board that makes it even easier to do. th-cam.com/video/ms_yqQ7_NSs/w-d-xo.html
This is exactly what Ive wanted to do for So Long! Thank you, Thank you!
Thanks for watching! You may want to take a look at this board, it does everything that the Amazon one does but without having to do a hack, and it a smaller footprint. There's a video about it on the product page.

Steve..i still think you are incredible!!! Great Hack idea!!
Love to show people how they need to look at something and think "how can I change that to work for me?" Sure, there might already be a solution, but it isn't as fun to do :)
Hi Steve! Thanks for another great video full of useful information. I'm really enjoying this series and looking forward to the next installment. Hoping to see you do something with Arduino in the future.
Thanks for watching, I really appreciate it. An Arduino project is up next
I can see some interesting Halloween applications for this . . . but . . . wire it for a wall wort instead of batteries, use the HD relay to switch several large floodlights, disconnect the speaker and send the audio to a PA System, and for the MP3, sample a clip from an old war movie - one where POWs are escaping {sirens, dogs barking, guards yelling, machine gun fire, etc}. Then set it up in my garden for the next time one of the neighborhood teenagers sneaks over my back fence to steal my watermelons! 😁
I get quite a few security companies interested in our sound cards for just that purpose, mostly verbal warnings.
Great video. Here are a suggestion to make it even more useful. You could tap the positive for the relay board off of the power switch's on terminal instead of the battery connection. This would eliminate the need to remove the batteries when you are not using it. Another thing in the future may also be to add a barrel jack to the board to allow it to run from a 5V wall wart instead of the batteries. This would give you the power to run your larger relay board or multiple relays as you suggested at the end of your video for multiple light control. If you use a 3 pin barrel jack wired correctly, then the device would work on either the batteries or the wall wart again, without the need to remove the batteries.
Those are all good ideas, I was going to do a more extensive video with some power mods but then I found this board which is now our best seller that incorporates all those abilities.

Hi Steve, thanks for the awesome content!
I wanted to ask, is there an easy way you could add a wire to the motion detector to allow the motion to be captured a distance away from the location you want the sound to play from? For example, I am thinking of putting the motion sensor at the beginning of a hallway with a prop at the other end that I want to make a noise when someone first enters the hallway.
How would I go about this?
Hi! With that particular all in one unit the easiest way is probably just what you said. Open up hte unit, cut the speaker wires, and run a length of speaker cable to where you want the sound. Although it doesn't help you right now, I'm going to be doing a video on a wireless motion activated sound project.
Thank you for the video. I am trying a similar setup but I am using a dc motor off the relay. My question is where or what do I use to power the motor? Thank you.
You would have to use separate power supply for whatever you want to run when the sound plays. The relay is just a "switch" and doesn't provide any power. I state this because a lot of people think it does.
The led should have a flat spot.The flat spot side is your negative(cathode).
The shorter of the two leads is another way to tell which is negative.
@@TheMakersCave unless they are cut off flush on the circuit board.
Thank you for the video!
Can a louder/better quality speaker be installed?
Also, could multiple units be wired to one motion detector?
Hi, thanks for watching! You may want to check out this video as it allows for both a speaker and allows you to use powered computer speakers. It’s an all-in-one board that you don’t have to hack. All In One MP3 Relay Motion Sensor Board

could you also use the leads from the speaker and remove the sound part of it basically and have it just be a cheap motion trigger and let the prop make its noise. I've done this with the driveway alarms from harbor freight and just used the leads to the speaker.
Sure could. Just snip one of the speaker wires and put an mp3 file that plays the length you want the action for.
There are much cheaper ways of achieving motion sensing capabilities
Would this work to be able to wire to a wiper motor for my prop so the motion activator would turn the motor on with sound at the same time?
You may want to watch this video. This board does exactly what you are asking. We just got them back in stock today, they were extremely popular. You can buy the components to do it yourself or you can buy the kit completely assembled and ready to go. th-cam.com/video/ms_yqQ7_NSs/w-d-xo.html&lc=Ugz_LfDEVF1BL0J9bhl4AaABAg
Hi Steve! Questions about this hack. If you used the USB power block instead of batteries and wanted to trigger it with an external switch to the power (so the power is either on or off, triggering the sound when it’s on). How do you bypass the motion sensor? Unsolder it from the board? Would this option work? Similarly, if I use the updated board instead of this boxed board, and wanted to take the motion sensor out of the circuit and trigger it with an external switch, would that work?
let me take a look at the one i have here and I'll let you know, there may be a simpler solution.
I have the newer card and relay you used in the two videos with the grey zombie doll/prop. I wired your setup to a corpsed child skeleton last year in her rocking chair and it was very successful. I ordered the card/relay/motion sensor from you after our haunt last year, but haven’t tried putting it on the new prop yet. We decided to make all the electric props powered from a manual button control box this year, so only one prop at a time is getting powered. We were worried the electrical system in the historic lighthouse might not carry everything at once, since we’ve added some new props.
Can you also use the wires from the speakers to turn on a relay?
The speaker wirers don't carry the type of current you need to activate a relay. Not sure if you saw the video of another board I reviewed, but here's the link. It might be better for what you want. th-cam.com/video/ms_yqQ7_NSs/w-d-xo.html
Hi Steve, I want to make a little project with maybe about 4 to 8 servos with a pca9685 and a nano. They each need a power source. I just want one wire coming out of this project and plug in a wall. I cannot find the solution to this. Something I can buy?
What voltage do you want for the servos. I know the Nano and the servo board need 5V.
how long would this last being the batteries are in constant use?
Sadly I don't know that. I've never ran it off batteries and not long after I did this hack I found a sound card that does the same thing and works better.
How would you hard wire this to be able to use a power cord vs batteries?
Very simple actually. Use a USB pig tail. Solder the red to the battery compartment red and black to the bat comp black. Then use a phone charger brick to power. That’s the cable I show briefly in the video. gravedecor.com/product/usb-type-a-male-4-conductor-cable
Thank you so much!!
23:45 shouldn't see any smoke..lol.But ALL electronics run on smoke because when you let the smoke out, they stop working!!!
I was real young at a car garage and one of the mechanics made the "smoke" joke about a wiring harness. I thought it was really funny because earlier in the day I "smoked" an LED from a toy I took apart. My first lessen in current and power (P = I x E)
Do you have an amazon link?
No, I don't have an Amazon link, but I do have a website for the Halloween items. gravedecor.com
instead of the lamp is there a way you can do this with a strobe light?
Sure, is the strobe DC or AC?
@@TheMakersCave which do you recommend?
@@anthonygodinez8514 Now you have me eager for a project :) Are you just trying to get a strobe effect or lightning effect?
@@TheMakersCave good idea! I was thinking a strobe effect Like in haunts for a jump scare. Maybe it can play a scary loud sound with strobe lighting effects. Hope that makes sense.
Please there are lots who want a similar mp4 player so we can make haunted mirror
Thanks for watching, have one coming out today
@@TheMakersCave please let me know ASAP please
