A few boxes arrived this week, so I got started on the thrust measurement frame this weekend. I watched a number of videos on safe CFRP working procedures (since I'm cutting simple shapes myself at home), including the one in the previous post. I spent...
Switching platforms was a great call. I got back from a relaxing North Woods weekend and an Adafruit package was waiting; the Due hooked right up after getting my hands on Arduino 1.5.6-r2 (you need this version for Due support). I wired my 9DOF stick...
Lots of stuff shipped today (including the CFRP stock!!), so this evening I decided to dig into a few things on the list.Sensor dataI wrapped up the functions for pulling data out of the magnetometer and gyroscope. Other than the Y and Z gyro axis (which...
The ring box would feature four RGB LED’s and would be able to cycle through various colors. In addition to the RGB LED’s I put a bright white LED into the design to act as a spot light. Lastly, the box needed to be self powered and have a run-time of...
I finished assembling the Z carriage, I had to reduce the flange on the anti backlash nut for the Z axis to fit the space in the carriage. Mounted a temporary end stop for the Z axis, it limits the travel a little bit but it will work until I can...
I haven't had a lot of time to work on this, but yesterday while I was doing something else I put a piece of 1/4" aluminum on it to see what happens. I wasn't expecting it to work, I assumed it wasn't rigid enough to actually mill the aluminum, but it...
The following image shows one of the locations which are damaged by rust. We need to replace parts of the outer skin and support structure.To get better access to these locations, and wait with this until the welding and metal work skills got better,...
I've implemented all those coordinate conversions and added an "objects" widget that can be enabled in the on-screen menu. So far, this widget just displays the centroids of each sky patch as a little triangle. That a huge step forward, because the patches'...
Adds up to approximately $1000, for what I used. I intend to build another prototype using only 2 GPU's ($60), a mini ITX board($105), i5($160), 8-16 GB RAM($90-170), 1tb HDD($40), and an expandable mini ITX case ($95) that would not look out of...
I ordered two EcoPlus185 water pumps with an output of 158gal/hr and a head height of 4 feet. When they arrived, I placed one in the water trough and measured that I would need about two feet of vertical tubing. Across the top edge of the glass, I needed...
Found a very intresting chip.http://www.mouser.com/ds/2/149/FSAR001B-112572.pdfIt basically replaces the capacitor dropper. And based on my estimations it just enofe to handle the peak power draw of my curcit. Simpler and smaller board. I think i will...
THIS IS INCORRECT I was trying to find the cause of what seam like bad components. The irf640 were failing with no good reason i could point to. So i read the data sheet again... current fine, no one would pull 16 amps. Voltage possible the upper limit...
This project has the potential to be expanded upon quite a bit. Unfortunately, I just don't have the time to invest in exploring all the possibilities, but here's some ideas I had for things to look into:More apps: The current implementation of this...
Four way scrolling, all easily done with one finger. My first Arduino sketch attempt in the previous project log was awful, but a milestone for me. I really love the touch sensors now that I am more familiar with them. The Teensy 3.1 has twelve touch...
