    Eggtimer Classic............issues

    Hey everyone, I bought and built an Eggtimer Classic as a backup to my telemetrum. I'm finally jumping in to the eggtimer (the telemetrum was pretty easy to setup) and I've had nothing but issues trying to get into the programing of this thing. What I can gather after about an hour of...

    I500 L1 (name TBD)

    I kind of live by the idea of sending it way too hard and hoping it works out, so I figured I'd go for my L1 as my first rocket and first flight, with an I500. The rocket is all 54mm cardboard LOC tube and a plastic nosecone. It'll be carrying an Eggtimer Quantum and an Eggtimer TX. I'm gonna...

    I couldn't find any models of the Eggtimer Quasar G3 so I decided to make my own for designing a 3d printed e-bay. Feel free to use it for yourself:

    Strange Behavior from EggFinder LCD LED

    I have been working on putting together an EggFinder system which is a very long story but I am finally getting everything together and working. I am using a Eggfinder TX with an LCD screen and everything is working fine. The TX transmits to the LCD accurate position and I can use it to track...

    EggTimer Classic Rev D Beep Code Error

    Hello, I recently built an Eggtimer classic, and after getting it all assembled it gives the beep code of one high then one low beep, which should be a battery error. However, with the board configured for variable voltage, and a good 2s lipo that read 7.4v, I am confused on how the battery...

    LiPo Batteries and Chargers for Eggtimer Products

    I've got two Apogees that are built and an Ion that is still in pieces. I haven't been doing any rocket stuff for about a year and can't locate the nifty charger for the 1s LiPo batteries for the Apogees(I think I got it from Cris) I'll be needing a larger battery for the Ion and was looking at...

    3D Printing EggTimer Receiver box

    Finished building most of the Back Friday sale order then had to build a field box for the rev B5 receiver along with GPS and Voice. Bluetooth can be there to but for the moment just double side tape it to the base. There is an SCAD file for modifications, I warn you though, the code needs...

    Interconnecting ground station software??

    Recently I ordered an Eggtimer Quark and the associated telemetry module as well as a USB Dongle receiver(also from eggtimer) I chose this receiver because the handheld receiver seemed a bit small for my needs and I would prefer that the data be sent to my laptop through the USB Reciever...

    Use of an Eggfinder TX and Eggtimer Quantum in MD flight.

    Hello everyone! I'm currently a 4th year engineering student attempting my L2 certification flight soon on a MD 54mm rocket utilizing a Loki Research K960 (or K690, have yet to decide) motor. My plan is to use the Eggfinder TX and Quantum I purchased last year for telemetry but have a few...

    I'm starting assembly on the Ion, but I'm having trouble identifying the capacitors. It's supposed to have this: __ 3 .1 uF 1206 ceramic multilayer capacitor (brown) (not marked, but they;re in a PAPER carrier) But I don't see anything with a paper carrier and I can't identify anything...

    Apogee Peregrine

    My latest high power rocket is the slightly modified Apogee Peregrine. I purchased the kit last summer with the intent of building it stock and using it for my L2 attempt. Later I decided I didn't want to build another 4" high power rocket with a 38 mm motor mount. I purchased the parts from...

    Twitch, cool photo.

    Here is a great shot of my Madcow Twitch. The rocket was launched with an AT I180. The Eggtimer Apogee reported an altitude of 2937 feet. We lost sight of the rocket till the chute release deployed the main at 500 feet. It was a great flight even though I didn't see most of it!

    Eggtimer GPS question

    I just finished building the “whole enchilada” Eggtimer starter pack. And I have to say I’m very impressed! What seemed intimidating in the beginning quickly became a rapid way to perfect my soldering skills and increase my confidence in building electronics! Thank you! I love the fact it gives...

    I can not get results, followed the instructions but I must be doing something wrong. To get the passkey, connect a USB-Serial cable (the same cable that’s used with all Eggtimer Rocketry products) to the 3-pin header as follows: BLACK wire – GND WHITE wire – TX GREEN wire – not used Using...
