In this episode I am putting together the complete Type-N-Text mobile BLE terminal. This TNT device is controlled using a BBC micro:bit. It has an SPI LCD to display 72 characters and a full QWERTY keyboard scanned by a PSoC4. The TNT device has taken an unexpectedly large amount of time. I did not anticipate just how much work it would be to design, print, build and program a device with 66 3D printed parts, 64 switches and 3 MCUs. Designing the 60 key caps and 60 LCD font characters in particular took much longer than anticipated. I don't have time to improve the device styling right now, but everything fits and works well.
I am still trying to complete a few more blogs, but time is fast running out and I have already been working to 4:00 am every night for the past week and almost that much in the previous few weeks.
Upcoming blogs:
- how Stirling engines work
- micro:bit BLE radio
- start connecting some sensors to the PSoC6
