You can also build the clock by using the latest versions of the required files by downloading the special package after a 10$ donation. The files can only be used for education-hobby – non commercial purposes.
The package includes:
1- Reciprocating clock source code together with compiled HEX and other supporting files.
2- Sliding clock source codes together with compiled HEX and other supporting files.
3- Labcenter Proteus 8.10 simulation project file that also includes the circuit schematic.
4- Improved STL files for the product case for 3d printing.
5- Wider digits for improved reading of the clock data.
Here is the puchase link for the file package.
Your contribution will be used for paying the hosting fees of our site. Thank you for your support. The standard code is freely available below.
