An update on product availability, August 7th, 2022

We are currently taking orders for all products EXCEPT for the Eggtimer TRS, which has very uncertain availability in the near future due to component supply issues.   If you’re looking for these, send us an email ( and we’ll put you on the waiting list.  It may be a long wait… just letting you know.

We expect to have the RF products (GPS trackers and telemetry) by late August, parts are on the way.   We have altimeters in stock, although some components may be out of stock with the distributors, which may affect future availability.   If you want a Quark, Quantum, or Proton altimeter, we recommend that you order them now, or you may have to wait until the end of the year.


Welcome to Eggtimer Rocketry!

If you’re looking for information and/or support for your Eggtimer altimeters,  Eggfinder GPS Trackers, or other Eggtimer Rocketry products then you’re at the right place!   All of our products are unique in that they are kits, we try our best to make them easy to assemble; we use through-hole parts or 0805-or-larger SMT parts to make assembly easier.   It’s really not that hard, if you’ve ever built a kit from Ramsey or SparkFun then you won’t have any trouble building an Eggtimer Rocketry kit.  We abide by the old Heathkit motto:  “We won’t let you fail!”
