Make an ATTiny85 Laser LED Sign

- Today we are going to make a Laser LED Sign with a custom ATTiny85 PCB and laser cut base.
I go step by step through the PCB construction, all the way to programming the ATTiny85 chip.
Why did I use a custom ATTiny85 PCB instead of an Arduino nano? Well I wanted something super small and I only needed 1 GPIO + I had a bunch sitting in a drawer and they were getting lonely ;)
You can find a circuit schematic and laser and 3D printer design files in my hackster.io project...

The hardware I use to program the ATTiny85 chip is based on Brian Lough's ATTiny85 DIY Programer video...

love the blue tack idea for holding the board.
Thanks for the emphasizing the extra bit of code to the sketch regarding the 8000000 prescale. My sketch didn't work until I added the snippet of code. Well done!
That is a YES from me. Brilliant design and implementation.
Thanks Michael :-)
Really nifty tricks you mention (for assembling/soldering)
Awesome,your representation and explanation is superb,keep it up and thanks for sharing.
Your welcome!
Great project video Seon - I like these kind of instructional project videos, was awesome to watch, and makes me want to make a little ATTiny perf board project too!
Thanks Stephen - ATTiny85 is a pretty cool chip - lots of fun to play with :-)
Thanks for the instructional video from start to finish. I have a few projects in mind now.
I just discover your awesome channel Seon! Love it. Pretty cool projects with useful steps explained. Thanks a lot.
Thanks Jean, and welcome!
Not bad. I should show off my programing shield for uno. I have did this project as a workshop. I used the high density neopixels.
Looks awesome! Makes me want to get a laser cutter even more.
You should... they are great for soooo many things ;)
Great video with very clear explanations! If only I had a laser cutter...
You should get one... even just a small cheap one. So much fun and possibilities!
Wow, very nice project/tutorial!
Thanks Trent :-)
This makes complicated things look easy!! gives me hope haha :D
Hey Jon! Great to see you here! You going to start making stuff? :D
Nice one really nice they are. Take it these are for your children.
Thanks Gary! Yeah, for the kids, but they turned out a little bright to go in their room... I might have to add an LDR so I can reduce the brightness when it's in the dark.
Unexpected Maker that'll work they do look really good though. My daughter is well jealous lol
Top job pal!
Thanks mate!
Awesome, thank you 🙏
Glad you liked it Ivo :-)
Can you upload a tutorial, How make a acrylic led lamp with attiny and control remote?
WHAT IS THE BLACK BOX LIKE THING CALLED THAT YOU PASTED THE LED STRIP,IS IT AVAILABLE FOR BUYING ,THNKS
Perfect
Great video!
Thanks Stephen!
Hello, this is really interesting project. However I have a question: Why did you put capacitor in the circuit? (I don't have good background in electronics...)
It's a decoupling capacitor, to filter out potential voltage noise.
Nice. I wanna build one for my daughter. I have all the electronic parts in my lab. But how on earth do I get the name engraved in the acrylic?
I have a video planned on how to go about making the vertical signs - you can def do it without a laser cutter! Not sure when it's going to come out though - I have soooo many thing on the go right now, my head is spinning!
Unexpected Maker Seon for the rescue. Nice. So I’ll sit back and wait for it. Thanks.
i got the same question after finishing the vid :)
Nicely detailed project assembly video. Great stuff! But where do you get the acrylic signs from? Is this a project just for those who have their own laser engraver (to make the signs), although I guess you'd need a high power laser for etching transparent acrylic? Sorry for being clueless, but I haven't seen these acrylic signs before. :)
I have a follow-up video planned that goes over both laser cutting the vertical acrylic - and hand making them... You definitely don't need a laser cutter to make them... but a laser cutter allows for more detailed designs :-)
Awesome. I look forward to it. Perhaps a cheap CNC engraver could also do the job, instead of a more expensive (& dangerous) laser, if needed for a detailed / professional result? I was looking at one of those cheap (~$200+) 3 axis CNC engravers, but haven't yet decided if I can justify it / if worth spending the $200+ on it. I don't even have a 3D printer yet, but the one I want is the new Prusa i3 MK3, but that's looking like around NZ$1500 by the time I pay NZ customs. So that's also a hard justify! LOL :(
A cheap CNC is def worth looking into - It could be useful for all sorts of things. I also want to get a CNC, but I want something that can CNC aluminium ;) My MK3 Kit arrives tomorrow! I think I might be too impatient to do a build video...
OMG! You have a MK3 Kit arriving tomorrow!!! I'm sooo jealous! I'm guessing you must have ordered back in Feb? How much did AU customs add to the cost? I'm really looking forward to your YT review of your MK3 build and your initial use thoughts / experience. You might even encourage me to finally pushing the order now button. Unfortunately a big decision for those of us on a tight budget.
I *JUST* got notified it's now arriving today :-) No customs fees... DHL delivery is inclusive of customs from my experience. I ordered Feb 12th, after a month of indecision... but the second I pushed the "buy button" I've been 100000% impatient for it to arrive!
Hey! I have a question! I made the cicuit using a 1K resistance and a 220 microF capacitor, should the circuit work the same?
Just came across this video, very nice but you neglected to advise/show that you'll need to burn the bootloader onto the attiny85 first !
That's because you deport need to burn a bootloader first. You can just flash them directly in the Arduino IDE.
I like it
Suppose I wanted to power 3 or 4 1 watt 300ma leds with this chip, would it work?
Nope. Not directly from the IO pins. No micro-controller IO can do that. Most are rated for 20mA max. That's what Transistors and Mosfets are for :)
It is possible 100 neopixel with WS2812B and ATtiny85
Great sir
Can we use this ic for chanting mantra for (Jesus ) religious purpose pls kindly tell me
Sir I also study making vedio from you
