What commenters say

  • The clock's design is impressive, but the price of over 250 GBP may be prohibitively expensive for some buyers.
  • The use of a high multiplexing rate may help avoid flicker and ensure a clear display, but some commenters express concern about potential issues with photosensitive epilepsy.
  • The clock's automatic timezone setting feature is a notable achievement, given the complexity of determining timezone from GPS coordinates without an internet connection.
  • Some commenters question the clock's electromagnetic compatibility and suggest that it may not meet relevant standards, while others argue that the design is sufficient to minimize EMI issues.
  • The discussion highlights the trade-offs between design complexity, cost, and functionality in developing a precision clock.
  • The lack of a CE marking on the board raises concerns about the product's compliance with relevant regulations and the potential need for further testing.
