With the holidays over I'm only able to work on this about an hour each evening. I was using the Universal Hacker Radio software last night to look at the signal. I was able to get some data that looked correct, but mixed with a lot of garbage. I just need to continue playing with it. I'm...

I just picked up a RTL-SDR dongle and I've been playing with various signals. I've also been a long time Eggtimer user. I have working LCD receivers but I wanted to play around with using the SDR dongle to pick up and decode the signals from the HM-TRP transmitter on the Eggtimer modules. Maybe...

I’ve also heard they have a +/- 100ft accuracy. I wouldn’t want to temp fate. I typically use 400’ for our site. 300’ on a windy day and a light rocket. I’d be nervous going lower.

So after using my stock Creality CR-10 v2 for years I decided it was time for an update. I added a Swiss Micro NG Direct Drive Extruder / hotend and installed Klipper with my raspberry pi. I also moved the filament from the side to above the printer. It took some time to get Klipper...

It is and there is a setting to record on power up. That is how I use it. Assuming the launch pad isn’t too far away I can turn it on from my phone right before the launch. That way I don’t have to worry about it overheating and shutting down while I wait my turn. I’ve only had one launch so...

It’s the runcam split 4. Pics from various prints. The battery is on the sled with the altimeters.

I didn't realize that was a video. Wow! I love the spring load. I was trying to figure out how I was going to get the camera flush in one of my applications.

I was looking at the runcam thumb for a nosecone cam in my 38mm minimum diameter rocket. But it would end up with a vertical video. It is made to record with the camera horizontal.

I have a camera mounted on the outside facing down but I wanted a horizontal facing camera mounted internally. This pic is from before I painted. Video from camera:

I have a Mobius Mini camera and based on the documentation it should able to be started with an external voltage applied. I've never mounted it internally so I haven't tried to see if that would work.

I used a little thermal paste for the contact but used a bit of epoxy on the edges to hold it in place. I know it’s a little permanent but I couldn’t think of any way to keep it in place during flight.

I added a small heat sink to mine and I use a eggtimer WiFi switch so I don’t turn it on until right before launch. In case it sits on the pad a while waiting. I’ve only launched it a couple times but it hasn’t shut off during the flight yet.

Houston weather can’t be counted on so I paint in the garage. Cheap drop cloth on the ground and I built a pvc frame that I can easily dismantle. Wrap plastic around it. Box fan with the cheapest 20” air filter I can buy to vent out of the garage. I have two jack stands with a broom handle to...

That was the eggtimer voice that comes from the altimeters. When using a gps transmitter you don’t get the “ready for flight” and altitude announcements. But you do get the same voice reading the compass direction and distance to the rocket after landing. I have both receivers with a single...

I keep my printer in the closet and do all of my printing through Octoprint from my computer. I'm not sure I need the user controls the Sonic Pad gives me. I'd rather spend that money on upgrading to a direct drive extruder and getting rid of the bowden tube. It looks like more effort but I...

Oooh... This is my first time hearing about this. I haven't touched my setup in a long time but I would love a faster print. I have a Creality CR-10 v2, using Octoprint on a Rasberry Pi 4. Looks like I have a weekend project in my future.

I used the Oracle vinyl on my rocket because of TRF recommendations and I agree. It worked way better than the samples and other ones I bought to test. I’ve only launched it once without a clear coat. We’ll see how it holds up. The transfer tape makes a difference too. This was recommended...

That is brilliant! We have a large cutting mat and we haven’t done anything with it yet.

We recently purchased a Brother Scan-n-Cut. It cuts vinyl and fabric. It has the advantage that it will scan any image and create a cut-out for it. I've made vinyl letters and stencils for painting. The software will use any Windows font. My wife is a quilter so it was the perfect "share" toy...

On-Board video of my flight.
