Project 136: Thermal Imager Project Update 6: 2.2″ FLIR Lepton + Arduino Integration
I have received my FLIR lepton module, an dam currently trying to integrate it into my project. This is proving to be more difficult than I thought. Even though I have enough RAM on the nano to do this, the clock speed (16MHZ) may not be fast enough to grab the data from the Lepton […]
Project 136: Thermal Imager Project Update 5: 2.2″ Multiple Slaves on SPI Bus
SPI stands for Serial Periphral Interface, and it used with devices like microcontrollers to connect RAM, displays, sensors, etc. A very useful primer from Sparkfun is located HERE. This link provides a lot of theory on how SPI works, and on the two main ways of connecting multiple devices to the same SPI bus. SPI uses […]
Project 136: Thermal Imager Project Update 4: 2.2″ TFT LCD Screen and Multiple Slaves on SPI Bus
I have received and connected my 2.2″ Adafruit TFTLCD display. Unlike my previous display, I had no issues connecting this one. In additon to the Adafruit Core GFX library, I had to include the specific driver library for this display, which was ILI9340. I was able to run through all of the basic “Hello World” […]
P-152: Virtual World Concept Update 50: Chunked Levels of Detail Using Quad Trees Part 18
I have implemented and tested the Quad Tree Parsing System. I am not yet rendering the terrain from it yet, I have just tested the actual functionality of the code. The system works by comparing the players position in 3D Space to the position of the center of each node in the current tier, then, […]
Project 136: Thermal Imager Project Update 3: RAM Addon
I have added some additional RAM to my arduino board. I need at least 4.8KB’s of RAM, and the Arduino Nano (and Atmel Atmega 328 chip) has only 2KB. I have added a Microchip 23k256 chip using a 3.3v/v logic level converter. I am running the chip off of the Nano’s 3.3v line, and using the […]
P-102: Remote Drone: Project Update 2
I have completed the assembly of the first of the rear wheels and mountings. I bought a 12mm pillow block to insert the axle into, however, I had to file quite a bit off the axle to allow the 12mm axle to actually fit into the 12mm pillow block. I then cut the excess off […]
Project 136: Thermal Imager Project Update 2
I have spent the last few days attempting to connect the screen I purchases for this product to my Arduino Nano. It turns out that it is more complex that I thought. The screen I bought is a generic 2.4″ TFT LCD screen, which supports both 3.3V and 5V logic, so it should work fine […]
P-160: Metalworking Forge Update 7
I have completed another forging session. I have mostly finished smoothing and narrowing the blade, which was the last big task. I now need to straighten the blade (it is quite warped after the work I did to narrow its edge) and straighten the spine of the knife. I also need to finish the finger […]
