Making Devices
Open Source projects where we struggle with engineering, electronics, coding and who knows what else... In this case, Bytes Counter is a very simple digital tally counter, so hopefully you may find it interesting ;)
Table of Contents
About The Project
Bytes Counter is a simple Tally Counter for counting people in places, helping you in inventories, practising soldering or just counting things at work! The project was chosen to test some PCB manufacturer capabilities and experiment with both the XLP (Extreme Low-Power Technology) and the pic18LF14k50 itself
The PCB does not have any power button, since the project's approach is to use the XLP technology of the PIC. It only has two buttons: increase/decrease the count.
A buzzer helps you count anything without needing to read the display every time so that you can focus on your work.
Even after weeks or months, the count is kept while in deep sleep mode.
Built With
Build one
- Get the gerber files for the latest version: V1
- Send them to a PCB manufacturer (Our Sponsor is PCBWAY)
- Buy all the components from the Bill Of Materials
- Solder everything with the help of the schematic
- Burn the latest firmware
- Give us a Star to the respository ;)
Here it is an assembly video:
Usage
Instructions of use:
- Pressing "+" or "-" will increase/decrease the count.
- Long press "+" : Sound Event -> Activate/Deactivate buzzer sounds.
- Long press "-" : Reset event -> Reset the count.
- 60s without pressing any button: Deep Sleep Mode -> Display off.
- Any button pulsation will exit Deep Sleep Mode.
Roadmap
- Count up/down and show it on screen
- enable/disable sound when pressing buttons
- Low Power Consumption
- Lower the frequency of the microcontroller at minimum
- Enter deep sleep mode automatically
See the open issues for a full list of proposed features (and known issues).

Questions
How big is the BytesCounter PCB?
It measures 40 × 65 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BytesCounter use?
36 parts, built around the CC56-12EWA, ZLLS410TA, LTST-C171GKT and TMB12A05. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the BytesCounter KiCad files?
From the makingdevices/Bytes-Counter repository on GitHub, at the commit this page was made from: the board is v1/Kicad/BytesCounter/BytesCounter.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the BytesCounter design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
