Will it Fly? - 4' X 8' X 2" Foam Board Airplane

by Evan-inc. 26. September 2016 16:39

On Friday afternoons, the UAS Club hosts and event called “Foamy Fridays” on the lower intermural field. Club members often bring small and large home built airplanes modeled after the plans found on FliteTest.com.

Not to be outdone, my friends and I took a 4 foot by 8 foot piece of 2 in think foam board, attached a power 60 E-flight (lent to us from the university), and 2 very nice Hi-Tech servos (donated by Hi-Tech) to it and made it fly.

Using X2 6 cell 5,000mah batteries in parallel we could power the plane for about 10 minutes of mayhem and fun.

Here is a video.

Basketball Hexacopter Drop

by Evan-inc. 5. April 2016 17:58

The University has added a men’s and a women’s basketball team in the last year. For the opening game of each team the University asked me to use my custom build DJI 550 Frame Wheel to drop the game ball at the beginning of the game.

Here are some photos and videos.

Adding FPV to a Blade 350 Qx 3

by Evan-inc. 16. April 2015 16:14

Note this could be easily modified to work a QX 1 or QX 2

Flying with FPV is fun however Blade does not offer any turnkey options for doing so. Here is a quick guide to add FPV in a semi DIY manner.

First a shopping list (these items can be mixed and matched, and not all are necessary, just give a good assortment of items; also these items can be had for cheaper, just do some searching on eBay)

Second; the 350 QX3 has a cable that comes out from the body with ground; 12V; and a PWM signal on it. (Hint, the PWM could be used for a servo that adjusts tilt using the gimbal controls on your controller) Looking at the connector from the front, the top being the side with the latching point  (top is facing us in the picture below; starting from the left the pin order is as follows; Ground; 12V; No Connect; PWM. For this project we only need Ground and 12V. (I recommend checking these pins with a Multimeter)




Real life;

Now Use these pins to run ground and 12V to their respective pins on the FPV Transmitter


Next connect the GoPro cable to the mini USB port on your GoPro; it acts as a video out for our purposes.


Next, connect the other end to the FPV transmitter.


Tape and Zip-Tie your cable and transmitter to look something like this.


When complete;

Keep in mind FPV works on 5.8 GHz not 2.4 (this is what the blade transmitter/receiver uses) thus you should not notice any interference. Tune in your FPV goggles and transmitter per the documentation they came with.


GO Out and FLY!

Christmas Light controller

by Evan-inc. 22. December 2013 20:24

Typical store bought controllers are garbage…. And professional ones are expensive… so I made my own.

Seen here: a bank of relays and an Arduino

Close up of the relays, this board can be purchased on amazon for around $20, I got mine at a local store called vetco, link here: http://www.vetco.net/catalog/product_info.php?cPath=640&products_id=12829

Close up of Arduino and RTC module, they can both be purchased on amazon, or at vetco

Arduino:  http://www.vetco.net/catalog/product_info.php?cPath=640&products_id=13665

Rtc:   http://www.vetco.net/catalog/product_info.php?cPath=640&products_id=12866

Overview of the entire device, please note that due to the amount of plugs I used, if every one were to be used I would recommend switching to 240 V instead of 110V. When using 240 you can use 1 leg for half the light and the other for the rest, this will ensure you do not over tax the breaker. Please keep in mind that I used a WatStop to verify I was not pulling to many amps with this system.



Below is a link to a zip files containing all the code I have to the light, please not he code is rough and does need refinement, this code is open source, so use it however you wish.

Pc Mods

by Evan-inc. 22. December 2013 19:40

Mods I made to my pc, to add water cooling.

Where the radiator needed to go

Roughing out alignment

Making reference marks for later  

Hole that was created by the water jet, see below for link to the file.

Radiated and fan installed

Link to file mentioned above.

DXF Here: http://evan-inc.com//Evan-inc_data/Pictues/12.22.2013/fan%20mounting.DXF

Solid Works File Here: http://evan-inc.com//Evan-inc_data/Pictues/12.22.2013/fan%20mounting.SLDPRT

Note: the screws I used are #6 – 32 (length varies) and thus the model is tailored as such, take the SW file and modify the clearance hole to change it to match your scenario.

President's Clock

by Evan-inc. 1. November 2013 16:52

Seen here are some pictures of a clock driver board that I made to track the pulse coming off a clock module and then relay it back to an Arduino.

this is what the board looked like inside the clock

Here is the finished clock module

Here is a picture of the schematic I made that was sent out to a PCB house that made the board and retuned them to us for assembly.


Below is a help doc that I made to document the operation of the clock, it also has many good descriptive images.

Seattle Power Tool Races

by Evan-inc. 30. October 2013 20:42

For the past 2 years, during my time in IV many of my co-workers and I have participated in an event called the Seattle power tool races.

You can find information here: http://hazardfactory.org/ 

You can also read an article that IV put out about the races here: http://intellectualventureslab.com/?p=9699

The power tool race is a wonderful time to utilize and test your engineering capabilities and push them to the max. In this event you are your own client and as a result you can put as much or as little effort into your racer as you want. As it turns out the amount of planning that goes into these racers is minimal and as a result you are able to try things that you normally would not do. In my case, reversing the direction of an angle grinder, and then welding 2 of them together.

Below you can see the racers that our IV team entered into the races, along with a description.


The racer (above), humbly called “Fork You” is the racer that I mentioned in the previous paragraph, it consist of 2 angle grinders and a pitch fork, all purchased at Harbor Freight.

"Fork You" was awarded the "best in show" award seen here below:


This racer named, "The Scoop", was made by a co-worker of mine, Chris, his racer showcases one 7 inch angle grinder geared up with 2 6 in waterweed saw blades for wheels. Unfortunately Chris's racer did not race many times due to break downs.

This racer, “One Trick Pony”, won many awards and was a crowd favorite.

This racer, modeled after a drag race car and was probably the most well engineered racer to have ever entered into the running. Unfortunately it was beat by other racers that were faster than it.

This racer, The “Rat Racer”, was the first motorcycle racer to be entered into the races, and performed quite nicely.

These were the awards we received for our victories that day.

Welding Table

by Evan-inc. 24. June 2013 16:32
Here: my culminating project for my welding class was a new welding table for the class. It was made out of a one inch think steal plate, and other various materials we had at our disposal.

Here: I am welding end caps onto the legs with a 250 Flux core welder.
