Lasercut MyLittlePony CollectibleCardGame Action-Tokens

Recently I bought a 2-Player Starterdeck for the “My Litte Pony” CCG. One of the aspects of the game is managing you ActionsPoints.

The StarterBox did include some counters/tokens made from thin cartboard, but those are not easy to use. I also tried using dice to keep track of the actionpoints, but thats also not optimal.

Thats why I decided to create some tokens:

The material I used is Perspex (color-codes 2TL2 and 4TL1) in 3mm thickness.

 

The Design is based on My Little Pony Printable Cutie Marks which can be found on Thingiverse. I did some small modifications. The butterfly had some parts which were to small to lasercut; I enlarged those.

You can download the modified .eps files here: MLP.CCG.Tokens

Replace the battery of a Digital caliper with a supercap

I got the calipers off ebay (<10$) quite a while ago, but they kept draining the battery really fast. After i discovered this blogpost I decided to modify my calipers in a similar way.

Modified caliper with charging cable

The basic idea is the same:

  • replace the battery with a supercap
  • build a charging device

The only real difference compared to trevors project is the voltage used. I didnt have a 1.8V LDO around, so i decided to go with 3.3V.  An additional SI-Diode in the charging-path drops 0.7Volt, so the actual voltage for a charged cap is 2.6V which seems to be fine for the caliper (i did no long-time test yet). Also, with that diode one cant blow the cap by charging with reverse polarity.

I only used parts you can get from the german distributor Reichelt. The cap is a “SPK 1.0F”, the switch is called ‘T215″.

I did not much testing yet. But the cap kept enough power to work with the caliper even after 80 hours ‘standby’ 🙂
