Hi John, I read your countdown hard hat article and love it. Could you please post a “how to” for the electronics and programming, I’d like to make a countdown timer with my arduino duemilanove. Thanks

Could you do a post on how the actual violet wand circuitry work with schematics explained. I have been searching the internet like crazy to no avail. Can’t find anyone else with hands on technological experience.

Hello John, thank you for nice article regarding TX20. Iam currentlu using it with my Atmel chip and getting readings nicely. My CRC error rate is around 2 %, is this reasonable value for TX20 data packets ??

Just found an amazing aerial shot of yours of Piha/Lion Rock. As a fundraiser the Piha SLSC are doing a calendar this year and I would really really love to include that photo as one of the “Month” shots. Wasnt sure how to get in contact and ask permission so hopefully this gets to you in time as we are putting what photos we have together but we have nothing like that aerial shot.Amazing.
Tks Debi
