My personal adventures in amateur experimental rocketry
Musings on addiction, games as an art form, and Finnish car culture.
I’m quite aware that its been a little while since I’ve posted here.
Suffice it to say that personal matters (together with old fashioned writers block) have not given me the opportunity to write about or even build anything (rocketry … Read More
A short writeup about the launch of Henk, mainly so I can share some of the awesome pictures and video’s it produced
The first successful test of MM-38.
And it only took 2 years.
I’m making a note here: HUGE SUCCESS.
GLaDOS, Portal
Almost 2 years ago, I stepped out into a field, attempting to test this brand new motor I received, and utterly failed.
Today, I succeeded not only in testing … Read More
Another year, another compilation
It’s that time of year again, and since I started this tradition two years ago, I feel obligated to deliver the third yearly rocketry compilation.
I am not as proud of the editing in this one as I was of … Read More
The troubled launch of Perigee-2, which chose to pursue its passion of skywriting instead of going up as planned.
Also the first launch which had been equipped with avionics (A simple altimeter)
It all looked so easy when you did it on paper

and rocket motors did not blow up in your face.
On the 14’th of this month, … Read More
A rather lengthy report detailing the fantastic launch of BTIR-2, which reached more than a 100 meters of altitude, and was recovered intact to boot!
Due to the complexities of launching a full rocket, I have split up this report into 4 sections:
R-15
Igniter, Type IIb, HQ
Launch Setup
The Launch
After years of development, and a month of preparation, the first fully successful … Read More
The design and philosophy of BTIR-2 ‘Perigee’
Featuring modular design, 3d printing, and cool looking blueprints.
After the eventful launch of BTIR-1, and some consultation with a very patient expert, it was decided that BTIR-1 had some stability issues.
BTIR-2 is here to try and rectify this, because learning from mistakes is how learning works.
First … Read More
A field report of R-14, which produced more than 1.5 kilograms (!!) of force, and was recorded in 4K from a drone!
The test results from R-13, which is the second rocket to break the 1kg barrier, and which set a personal record in strength!
After the rather disappointing results of R-12, the plans were altered to test R-13 with a Type II igniter, to see if it would help with the pressure build up.
After a week off on vacation, work was … Read More
A report detailing the test of R-12, and why it went so differently than planned.
