Site updates:
1 December Sales of ‘Pen Repair’ have been excellent. All copies sold from over 1000 printed. No more will be printed until April/May 2010.
09 December The repair queue is 4 months long. I am only accepting repairs that cannot be done elsewhere or from old customers sending not more than three pens at a time. I am reducing my repair activities to concentrate on the design and production of tools, writing, and repairing pens for sale on this site.
05 January Some more Visofils for sale. The PFM’s went like ‘hot cakes’, but I have another - a grey PFM mint!
Sudoku Solver
This will provide you with an assessment of how difficult the puzzle is, and it will solve all the 9 by 9 puzzles that I have tried. If you would like a copy of my solver (written in Fortran!) please drop me an e-mail and let me know the operating system you have.
