I’ve finally added the power supply I’ve designed for the Thunderbolt. It’s a combined switching+linear design. It’s been running my own Thunderbolt for a while now. There’s a schematic on the store page and it can come with or without a 15W primary supply. https://www.tindie.com/products/nsayer/thunderbolt-power-board/
The second one will be up next week, and it’s a simple GPS clock. It has 7 seg LEDs for hour, minute, second and tenth of a second (the later is interpolated from the PPS). My educated guess is that the tenths are accurate to around 200 µs or so (the zeroeth is probably much better). It has support for +/- 12 hours of timezones, 12- or 24-hour time display (with AM and PM LEDs) and DST for US, EU or Australia (or off). It can come as a board-only “quick kit” (surface mount components all done and programmed, through-hole left for you to do), a “quick kit” with a laser cut wood and acrylic case and plug-in power supply, or assembled (in the case, with the power supply). It has an SMA jack for an external antenna (that is not included). 3.3V is supplied for active antennas. Board-only quick kit will be $59.99, assembled $99.99. I’m just waiting for the inventory of boards to come in before I activate that store listing. But for now, there’s the Hackaday project page: htt ps://hackaday.io/project/18501-gps-clock _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
