Control Station

Finished up on my control station, this will allow me to test the rocket up to 500 ft away. I am using an older I7 laptop with windows 7 loaded with Arduino software for the Mega control board and some cool switches that turn everything on. Little pouch on the side that holds a wireless mouse and underneath the laptop is a 12v power supply, power strip and a switching board that I made. The wire harness on the right will connect the rocket to its power supply. Below is the energy station that will be separated from the rocket for added safety. That is still a work in progress as I slowly acquire the needed fittings and wire up the connections.

Just started building the test frame, I don’t have a facility to test so I will create a stand and weight it down with sandbags. I still need to put the strengthening supports on but just getting it on the stand is pretty exciting. Still need to finish the control board, finish wiring and hooking up fuel and oxidizer tanks. I am also building a control station with a 500 foot line so I can stay far enough away to stay safe. Little by little I am making progress, I just have to take my time and not rush the finishing steps to make everything as safe as possible.

Continue the build of Rocket Engine

Rocket_Engine_Build_01_2019.jpg

Main engine is finally assembled, need to build a test stand, hook up ignition power source, fuel lines and Nitrous Oxide canister, and I still need to finish the build of the control board. A little at a time, seems like time is my most valuable resource. Had a good but busy holiday season, not going to make any estimates this time, just going to keep on working whenever i get the time. I am very excited with my progress, actually having the main assembly together is a big motivator. This should be an exciting year, lots more to do.

Rocket Engine Assembly

It has been a long time coming, the parts are made and I have begun putting the main sections of the engine together. I will be using an Ardruino MEGA board along with some MOSFETS to control fuel and ignition. I will get a few days off for Christmas and that should give me the time to finish assembly and then it will be time for testing. Hoping to get my hands on a few GoPros to record it. Have a great holiday season.

3D Printing in Space

Just playing around with an idea for 3D printing in Orbit. This idea would print out structural beams for large structures. When the print is done the robotic arm places the beam on a Space barge and using something like multiple VASMIR drives to move itself to a nearby construction site. Printing material will be refilled by replacing the tanks on the end, This idea might be a little to open and proned to losing a beam now and then. I will continue to contemplate something better, still pretting cool though. 

Regolith

Came up with an idea for collecting regolith on the Moon.

The rover will ride across the surface with the sweeper spinning fast and moving the material to a fast moving conveyor that will accelerate the moon dust and slide it up the U-ramp and over the containment box. It will make quite the mess but be a very simple design. As long as most of the parts are sealed or covered with a non-degrading rubber like boot to keep the regolith from penetrating any joints or bushings it should last a long time with very little maintenance. The rover will have sensors and connectors on the front bumper to know where it is going and to connect to a terminal to recharge and deposit its cargo. The terminal will remove the cargo box much like a ground based garbage truck.
