Hello everyone,
I've improved upon the tide-to-go pressure pen.
I'm assuming that you've already read about it, so if you haven't you should have a quick glance at the post:
http://www.wiimoteproject.com/ir-pens/idea-for-a-pressure-sensitive-ir-pen/The old pen was a bit fiddly with the assembly - the wires would interfere with the spring mechanism.
Now the wire IS the spring mechanism. The pen also now uses the entire tide-to-go pen and an AAA battery.
I've included some photos of the pen and a short video of the spring mechanism and the working pen.
I'll try to post a video of the pen in actual action soon, so you can get a sense of how well it writes.
I hope the video shows how sensitive the pen is - others pens that I've seen look like you have to push down really hard.
