Is it okay if I use chronodot v2.0 instead of chronodot v2.1?

Good job. BUT how many schools have the laser cut machine?

Man that was a freaking awesome video. Gonna learn some video making skills from you. By the way congrats for winning rainbow contest. Well done.
Looks like Inkscape decided to go against the 72 ppi standard, and everything you've exported is in 90ppi, which means that I cut a 20 inch clock. Oops. If i were to do some formatting for .ai and .cdr, and forcing all the line widths to 'hairline'/.001 where many lasers expect, would you be interested in adding those to the laser files in your repo? I'd be happy to submit a pull request.
What a fantastic project. I have just bought a laser cutter and this will demo its benefits so well. My neo-pixels arrived today can't wait to start making - I didn't know that these existed before seeing this, really exciting!
Aha, I only said that it was doable, not that it is easy but there are ways to make it easier. You could increase the width between the segments to stiffen them and if you glue the acrylic pieces to the back of the front board then you that will reinforce the segment cutout panel further. I have tried cutting out those segments on my home made cnc router and the pieces between the segments broke when I was using mdf and even with ply .However, if you make the front\ really only as a facia and the build the rest of the enclosure but you should end up with a the look that you want.See ifn you can get hold of some jig saw blade that are thin, mostly used for cutting veneers and such. As you have probably deduced, I am changing the way that the AUTHOR built his project but only because I understand more about cutting stuff out of various materials than I will ever understand about coding and pixie wrangling so perhaps look at the instructable like a student essay, read and correct perhaps, make your changes as if notes in the margin/
I forgot to say that MDF ( or HDF if you can get it ) is better for cutting as it sands easier than play and doesn't leave a furry edge or tear out on cross grain but the MDF needs to be sealed all around with shellac or similar, pay close attention to the edges, to keep it from warping and swelling with time.
Hi glennorp, I find your posts a little puzzling because being a teacher you already know that very little knowledge is known, it is all the result of learning. . Soldering a basic joint takes about 2 minutes to learn ( most people who say that they can't solder have either never tried or never read a "how to " on the subject) A lazer cutter will just do the same job as a jigsaw but a bit faster. For a template you could import a picture of the seven segments into inkscape, export and print them full size that you want and glue them onto the board you choose and cut them out with your jigsaw and clean up the edges with some sandpaper.By the comments that you have made it seems to me that you want to have a go so perhaps, just start with cutting out the seven segment pieces first before buying the rest of the parts, 6mm (1/4inch) is easy to cut using a metal cutting blade and is easy to sand straight and smooth and is only a couple of dollars and when you are happy with that then consider buying the rest of the parts. I have 2 autistic grandkids and am going to build some of these for them and their school to replace the ones that I made that just have different colours for different events ( I hadn't thought of making an actual clock so thanks AUTHOR ) and I have just ordered all the electronic parts for $A18 delivered from our Asian friends and the perspex I get from a plastics factory from their off cuts bin for a case of Fosters for a boot full: you don't need a full sheet, just enough to cover the holes. Good luck with your project as being a teacher I believe that you already have all the skills required to achieve your goal.
Thanks for posting this great idea and for all the work involved to bring it to us. I am going to have a go but change a few things and include a wifi NRF24L01+ 2.4GHz Wireless RF Transceiver Module and addressable led strips as well as cheaper parts, hopefully your code will still work with MINOR mods as getting my head around coding is causing the rest of my hair to fall out.
i would definitely buy this kit for less than 100 dollars
I think maybe even some service bureaus allow you to upload plans and put together all the (laser cut) parts in a BOM so others can purchase as a kit. That would be great as well... - tastewar
great idea, beatiful design and amazing videotutorial!How could we connect the "clasroom clock" w/a mobile? Is ti possible? To control some of its features via wifi? - lucasrib1
