Hey Angela, you have no idea how happy it makes me to see someone enjoy the design! Thanks for uploading the result, it looks amazing in plywood. Glad the ratios match with a properly calibrated machine as well :)

Thanks!

Hey Joseph, it seems the file was corrupted somehow - I tried downloading it and got a 38Mb file where my original upload was only 138Kb (it's just a few lines!). I've reuploaded it in different formats and they all seem to work fine now. Happy making!

Thanks! Let us know if you make one!

Hey Taran, I'll try to find the time to do that. Not sure I understand what you mean though - could you describe what exactly you'd like to achieve?

Very simple yet effective. Quite ingenius!

Arduino has a built in timer (although it's reset every time the power unplugs), not sure about the Pi but probably has it as well. You could reset the time once a day by connecting to the smartphone's clock to ensure accuracy.Alternatively you could use an RTC module to keep track of time.

Hehe, can't say I needed more than one diode either. For now.

Cool tutorial! Definitely a fun way to learn about new parts. I order electronic parts in bulk from AliExpress, it's unbelievably cheap and haven't had a single malfunctioning part. Recently bought 100 diodes for 0.65 euro, including shipping.

I agree that smoke machines are generally not kids toys and you should always put them out of reach (also because the smoke can be hot too close up). The main concern I have with what you built is that if some part gets loose while it is in use, it would start a fire. For example, you used hot glue which melts at 120-200 degrees (depending on the brand, some hot glues start to soften at a temperature of 60-80 degrees) to secure two irons that can easily heat up to 250-350 degrees celsius, in a tiny enclosure, and you are running it for hours. And what if someone bumps into it? Let's say it falls down from a table - will the plywood and adhesive hold? Maybe you used high temperature hot glue and maybe yours will hold, but I would still not advise anyone to try to replicate it this way for…

This is a nice explanation of how a smoke machine works, but I would advise against putting a hot soldering iron anywhere near a party. That seems incredibly dangerous and a bit unnecessary, given that smoke machines are barely more expensive than soldering irons.

This looks really cool, but you didn't actually describe what it does when you flip the switch. Is it just an on/off switch, meaning you're angry when the leds are on?

This must be one of the most extensive instructables in existence. The end result looks pretty awesome too, bravo!

Very simple and still good looking. Cool tutorial!

Thanks! It's amazing what you can do with waste products sometimes :)
