An update on product availability, August 28th, 2022

We are currently out of Eggtimer Quarks, Quantums, and Protons… we’re waiting for a part that’s due in mid-October.   If you’re looking for one of these, send us an email ( and we’ll put you on the waiting list.

We are also not taking orders for the Eggtimer TRS, we’re out of them and it 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. 

The remaining products (altimeters, switches, GPS trackers, telemetry products) are available to order, either in stock or with a short lead time.


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!”
