Why create yet another stylus?
My daughter is studying fine art at A Level in the UK and uses her iPad to record ideas and sketches. After trying a few different types of stylus it was clear that nothing available suited her fluid drawing style. I decided to create a stylus that met all of her requirements.
The PLiM in action
Getting it together
The first prototypes were created in one corner of my garage using fairly crude tools including hacksaws and wire cutters; the production versions are precision engineered on 6m long lathes turning the shaft and tiny stainless tip components. It is really satisfying to see an idea come to fruition especially when all development work is (literally) carried out in house.
Over 30 changes were made to the original design taking into account function, aesthetics, materials, mass, component manufacture, ergonomics and cost.
Sourcing materials and components is always a lengthy process especially for small batch production. The key to the affordability of the PLiM relies on the use of the stainless steel eyebrow piercing in the stylus tip; this was stumbled on by accident when watching TV. The use of nitrile (black) and silicone (red) o-rings for the grip also avoids over engineering the solution.
One dilemma remained; how to protect the the iPad touchscreen. All of the PLiM tips are hand polished and cleaned; but after reading huge amounts of feed back for other flat faced stylus I came to the conclusion that the only way to remove the risk would be to design the tip to work on a touch screen with a screen protector fitted at all times. As the whole stylus is constructed of metal it has no problem registering on a touch screen even with a screen protector fitted. The glass cloth tip protectors are to reduce marking of the screen protector to an absolute minimum and they do a really good job of this. They also allow the tip to glide on the screen protector by reducing friction.
Early Kickstarter backers will get a free laser cut hand buffed 3mm statinless steel keyring.
