Can you identify the pinout of a TrackPoint?
If you’re lucky, someone has already identified the pinout of the trackpoint you have (see pinouts ), or at least a similar one. If not, you’ll need to identify the pinout yourself, here are some tips: The largest tracer is most likely GND.
How to make a track point for a keyboard?
Trackpoint module (salvaged from old thinkpad or new tp keyboard). Veroboard (for reset circuit). Reset circuit components (4.7k resistors x2, 100k resistor, 2.2uF capacitor). Stem for trackpoint (labret cheek piercing 16G). Double sided tape (for testing stem lengths before gluing). Cutting knife (x-acto, nt-cutter, japanese knife, etc.).
Do you need a TrackPoint for a teensy keyboard?
As far as I know, USART is the recommended implementation, as it uses hardware for PS/2 signal receive. You will need to use D2 (data) and D5 (clock) on the teensy though. Keyboard with at least 6mm clearance between switch and base plates, depending on the trackpoint module height.
What are the pins on a teensy 2.0 keyboard?
Teensy 2.0 (pins D2 and D5 available for USART). Trackpoint module (salvaged from old thinkpad or new tp keyboard). Veroboard (for reset circuit). Reset circuit components (4.7k resistors x2, 100k resistor, 2.2uF capacitor). Stem for trackpoint (labret cheek piercing 16G).
What’s the best way to cut a track point?
Cutting knife (x-acto, nt-cutter, japanese knife, etc.) Using the cutting knife, perform 5-10 cuts on both sides. Using a little pressure, snap the board on the cut. Use sandpaper to smooth out the cut edges.
Where does the TrackPoint go on a Cherry MX switch?
My trackpoint pointer base sits flush under my 3mm switch plate, and with a cherry MX switch having a height 10.2mm above the switch plate, and about 1-2mm PBT cherry keycap on top, the 14mm stem with 3mm ball is kind of perfect. For extra friction on the ball, I used some sandpaper.
