[time-nuts] Re: 1 pps / Gerber files
DaveM is absolutely right -- JLCPCB is crazy cheap (and great quality) for small runs of PCBs, esp. in the default config (green soldermask PCBs, simple HASL (leaded) finish, 0.062" thick, et.). When I do PCBs I often choose alternate soldermask colors (there's a madness to the method :-) ), and I pretty much always go with ENIG (gold finish), to avoid any corrosion issues, etc. But that adds an easy $20-$40/board. If you want the absolute cheapest way to go, follow DaveM's instructions! It's a great way for folks who are not yet experienced with PCBs to get into handling PCBs, esp. if someone else is providing the Gerbers (the source files for making the PCBs). (At this point in my life I have designed around well over 500 PCBs). --Andrew Andrew E.

[time-nuts] Re: 1 pps / Gerber files
To all who are interested in Gerhard's boards; If you just send a zip file of the Gerber files that Gerhard has provided to JLCPCB, you can get 5 boards, including shipping to your address (I'm in the USA; I can't say what shipping would be to other countries) for a grand total of $5.90 USD. The board manufacturing cost is $2.00 for all 5 boards, shipping is a measly $3.90. PCB build time is 1-2 days. Shipping is fast and reliable. I've used DHL for previous orders, usually arriving within a week. They accept Paypal for payment. By ordering boards yourself, you get 5 boards, for less money than having to go through a 3rd party, and avoiding USPO costs and delays.

[time-nuts] Deep Space Atomic Clock : Poster
A creative team of visual strategists at JPL, known as "The Studio," created a poster series, which is titled "Visions of the Future." Nine artists, designers, and illustrators were involved in designing the 14 posters, which are the result of many brainstorming sessions with JPL scientists, engineers, and expert communicators. https://www.jpl.nasa.gov/galleries/visions-of-the-future Included in this JPL Poster Gallery is a “Time-Nuts” poster (3) about the NASA Deep Space Atomic Clock (red, orange, and blue with different highlights). JPL permits the downloading of these posters (20” x 30”). You can work with local printer resources (personal or professional) for mounting or framing. Details on JPL web pages.
