  1. Hi, will you build and offer this for sale? I am not electronically literate enough to build it on my own, but would consider buying it.

    1. Thanks for your comment on the swim timer. I’ve made a few small improvements to the timer and have been using it continuously since I put the article up. I find it very helpful but I just don’t know if there are enough people that swim in the dark to justify turning the design into a product.

      Currently I have no plans build it and offer it for sale. If I had a better idea of the potential market I’d consider it.
