Hi Guys!
After some time, after I learned some other useful things like how to design the PCB's in KiCad and how to make vector images in InkScape for laser cutting, I have made the Vectre Lightpen with buttons 2.0. 🙂
The basic concept is the same (it is derived from old "version C") but since now I can use PCB's instead prototyping boards and laser cut acrylic sheets instead drilling into the generic project box, the assembling is a bit easier and faster.
The changes/improvements comparing to the old design are:
1. Most of the electronic component were moved from the pen into the connection box (the box where all the cables meet) so it allowed me to use the thinner cable (since less wires are needed) for the pen itself so it is more flexible and feels better when moving the pen around while drawing
2. Plastic joystick connector instead the metal one: metal connectors are often "shaving" the edges of the plastic connector when not inserted straight, and black connector looks more compatible with the vintage console
3. The connection box is made by laser cut acrylic sheet. Because I have used simple assembling with just bottom and top sheet, the inside of the box is exposed which some people might not like, but on the other hand the black acrylic is much more shiny and I could also laser engrave my logo into it. 🙂 The PCB in the box is black so it fits nicely visually.
I have used metal spacers and bolts to add some weight to the box so that it sits more nicely on the table.
I have to make slight changes in the PCB and box design based on the experience with assembling the first batch, after that I will publish on github all the files I have used to build it if somebody would like to build his own (you will still have to find the pen shell to fit into). For those who do not feel skilled to build their own I will sell a few either completely assembled, or probably also some cheaper partially assembled. Unlike with the old pen I will not anymore issue the certificate of authenticity or out serial numbers on it.
I will as with the old version make also few red coloured version of the lightpen.
