365 laser cut items in 365 days. I provide the files so you can make your own copies and if you don't have access to a laser then I sell most items too.

Inspired by the King of Randoms Micro crossbow on Instructables I decided to up the ante a little and laser cut a matching crossbow but this one has a trigger to launch the projectile. I'll be writing an instructable for it shortly but for now here is the file (svg here).

Clearly I'm in a festive mood this evening because I've made 2 more characters to go with the snowman.(svg here)
They're now available in my shops too
I made this light beacon for EMF camp (you can just about see it in this post). It sat on top of the laser and span round slowly shifting between 2 colours all weekend. People like Blinkenlights and I got a few compliments on it, especially as we left it running in the dark all night. Not bad for something slung together in a field. I never got round to posting it. I had a lot of fun with yesterdays alarm clock though so I thought I'd resurrect it and put a whole bunch of new patterns into it.
I didn't quite get as many done today as I hoped but I did have fun coding and I also got electrocuted by it (entirely my own fault). I have at least set up a framework for adding animations, so next EMF camp/Maker faire I can just add patterns as I think of them. Here is a short video of the 4 patterns it now cycles through. It's no LED cube but it's a start.

This item is nearly 12 months overdue but I'm really pleased I actually got round to finishing it. It's another small stellated dodecahedron but it is much better known as Gravitation by M.C. Escher. 12 Turtles sit amongst the shape, the turtles are not fixed down instead relying on the framework to hold them in place. When rotated the turtles rattle around which makes a pleasing noise. Each turtle outline was cut from ply and painted before it was returned to the laser cutter to have the details added to it.
Eli sleeps with a little Gro Clock in his bedroom, for those that don't know it's an alarm clock the switches between a day and a night image so children who can't tell the time know when it's acceptable to get up in the morning. I would recommend them. Sadly I left ours at Grannies after the weekend and Eli wasn't keen to sleep without it. So I rummaged round the garage, found some parts I knew were out there and knocked together this arduino based version of the same clock. Being Arduino relied on the existing libraries to write the code quickly.
- Power for the whole arrangement comes through the USB connection
5V, GND from both the RTC and the Neopixel Ring are connected to the Arduino.
- Data in from the Neopixel Ring connects to Digital input 2 on the Arduino
- SCL of the RTC goes to Analogue input 5 on the Arduino
- SDA of the RTC goes to Analogue input 4 on the Arduino
- Wire Library - for connecting to the RTC with I2C
- DS1307RTC Library - for understanding what the RTC says over I2C
- Time Library - lets the Arduino understand times
- TimeAlarms Library - executes functions at specific times/intervals
- FastLED Library - for communicating with the NeoPixel ring
Full source is available for download from here
- The first lines of the setup function define the time that the alarm will go off
- The RTC and Neopixel ring are initialised
- Two alarms are created, one at the time previously specified another an hour later
- The main loop of the program does nothing except create a delay that keeps the timer ticking
- LightsOn function, creates the short sunshine animation when the alarm goes off
- LightsOff function, switches the LED's back to night time colour

I'm heading to a local craft faire at the start of December and I wanted to make something Christmassy and pocket money priced. Given that the previous tessellations have gone down well I thought these Koch Snowflakes tick all the boxes will still being geeky and Mathemagical. I'll let you know if they sell well :)
After several requests these snowflakes are now up for sale in my webstores

I've had my Whitetooth laser cutter for about 6 weeks now, it was pretty much dumped in the middle of the garage, wired up and left to run. The extraction used 150mm pipe and the hole in the wall was 100mm so I've been opening the garage door whenever I wanted to laser cut. This week I finally got round to connecting it in properly and sorted out the tangled mess of wires. I still need to connect in the Blacknose to the extraction system and I'm waiting on a T piece to do that but it's starting to look pretty good out there. Oh and I do need to find a better way to keep the laptops on their precarious perches.
As the title says, it's a small stellated dodecahedron. 12 identical panels interweave to form this dodecahedron shape. The ends clip together and hold in place although my stuff gets handled quite a bit so I put some glue in there too. It's very much an assembly puzzle but not as complicated as the Frabjous. (svg here)
This was made from 1.5mm external ply which is nasty to cut and is proper black all the way round the edge. Thankfully I think I've worn most of the charcoal off with the assembly. I keep meaning to rant about how poor quality the 1.5mm ply is because everyone passes off external ply as laserable, but I think there may be a new supplier in town shortly with some better quality stuff so I'll wait for that to happen and then shout their praise from the rooftops (again)
