Nitrous Oxide Production

I am currently designing a device that makes racing nitro. For anybody that plays racing games, this is probably familiar. It is one of the fuels this engine is designed to burn. From the diagram, you can see that it heats ammonium nitrate to create water vapor and N20. I can get ammonium nitrate for about $.15 a gram, which is great compared to $200-300 per bottle of N20. More details to come.

Kickstarter


Yay! Our kickstarter project is going live this week! We have project descriptions, and other information about this project now available to the general public. The link to the project will be posted when the kickstarter goes live!

A DIY tutorial on custom BNC wires

A DIY tutorial on custom BNC wires 


 Here are the supplies you'll need for this project:








 1/4" ID spring (I found this in my stash of electronics so your going to have to work to find this one!)

 6-8 inch male to male breadboard wire (can be found on ebay or electronic goldmine)
 Standard BNC terminator (can also be found at Home Depot)
 1/4" OD plastic tubing (can be found at Home Depot)
 I'm going to start by cutting my tubing slightly shorter then the breadboard wire.
 I will then cut slits in the tubing about a half inch apart and about half the way through the tubing. This will allow the tube to bend easily.
 Take the breadboard wire and straighten it so it will slip easily into the BNC terminator.
 It will require very little force, and you can feel it slide into the connector. You can get a compression tool to fix it there but I didn't worry about it.
 Slip the plastic tubing over the wire, and into the BNC compression end.

 Now slip the spring over the tubing as seen here.

This provides for a protected from the environment and it is quite awesome! I use this to connect to my digital oscilloscope interface all the time!

Update - Hybrid Rocket Engine: Motor controller and servo mounting

I've designed a mounting plate system (which uses parts available from home depot as usual!) that allows for a cleaner setup and mounting away from the flame output nozzle. It uses Plexiglas main plates that screw right on to the main chassis. If I can get my budget coordinated, I should be able to build this portion in the next 2-3 weeks.

Update - Hybrid Rocket Engine

 Just a few updates have been made to the engine. They mostly enhance the automation of the system.
 I built some custom BNC cables that allow me to transfer custom built sensors to a digital oscilloscope interface.
 The custom cables link down to the main data transfer breadboard, where everything eventually meets and connects.
I bought some BNC connectors from Home Depot and wired a pinnned cable into it and covered it with some acrylic tubing. Very Simple!

Old Electron Guns

Here are some old designs I made about a year and a half ago. Inside there is a filament, and an accelerator grid. All the wires come out and move to the back to be hooked to a psu.


Hybrid Rocket Engine

I have recently been putting together a semi-autonomous hybrid rocket engine, this is a prototype edition, complete with plexi-glass mounting plates. It is run by an Arduino Mega 2560. It has three sensors, an accelerometer, a gyro, and a vibration sensor, all of which are protected and covered (see pictures). It burns a propane flame, mixed with a pvc solid fuel, and pure oxygen gas that is produced with a chemical reaction on the engine itself (see three silver chambers). Please comment!
