LulzBot Mini: LED Lighting Controller

Update: Check out the more recent mod – camera mount and better lighting. So, I just got my LulzBot Mini this week and have to say I love this thing.  It’s my 2nd 3D printer (I Kickstarted the M3D – but it was not a reliable machine).  Anyway, like any guy with a new toy, I had to do something to make it my own!   ..and why not print some parts for it!...

250 Carbon Fibre Quad Build

I recently downsized from my 450 quad to a ZMR 250 unit.   The purpose of this post is not so much of a step-by-step but rather a collection of tips, suggestions and lesson’s learned to help should you go down a similar avenue to build your own quad.   There are plenty of video’s and how-to’s out there once you know what set-up you want to go with.  I will reference mine as well...

Micro MinimOSD – D4R-II RSSI using RC Filter

I’m running a Flip32+ using a D4R-II receiver and wanted to get RSSI into the Micro MinimOSD.   Googling yielded other results that did not work for me.  After digging deeper, I found this worked for my set-up.  The solution is an analog RC filter consisting of a cap and few resistors.  The idea is to convert the PWM signal to an analog signal so it can be interpreted correctly.  Analog will provide an...

10 Minute Project – Glowy Pumpkin

Here’s a quick project to get some funky flashing / colour changing LEDs into your pumpkin. Just grab a set of addressable WS2812‘s and some Arduino code and your’re done.    The 2812’s are pretty easy to wire up.  Essentially, +5v, GND and data signal get daisy changed through the set of LEDs.  Each LED has 3 pins for IN and 3 pins out.  Wire from the Arduino to the first IN set, then...

Micro MinimOSD – Gray Screen – A Fix

Symptom Summary: With the camera plugged in, the OSD would not display the telemetry overlay and only show the camera view. Then, when the camera is disconnected (power), the OSD would show telemtry, but no camera view. This is a repeatable activity.  I also verified that my RXTX were connected correctly (was able to see the OSD change when moving the quad so I knew this was working). Solution: Fix:  Although this may have...

Quadcopter: 3D Printed Leveling Workstand

I often mess around with my quad configuration.   Sometimes I re-flash the firmware which requires the re-calibration of the accelerometer and magnetometer.    To calibrating the accelerometer, the quad has to be on a level surface.  I have a 4-in-1 Quattro ESC mounted to the bottom, which makes an excellent platform to mount to.  After tinkering on TinkerCAD (see what I did there?) for a few minutes, a base was born.  I also...

In-Flight Rate Profile Changes – Cleanflight

As I gain more experience flying, I want to have the ability to swap rate profiles while in flight.  Some days I want easy flying, while others I want things a little more aggressive so I can do flips etc.  Cleanflight has the ability to set profiles in the PID Tuning tab.  You can set different PID values as well as RC Rate etc and save them to 1 of 3 profiles.   Values...

Configuring Lost Model Alarm – Flip 32 and Cleanflight

Earlier, I created an enhanced lost model alarm using an ATTiny85 and some Arduino code.  I wanted to have different alarm modes that could be triggered depending on the position of the pitch trim pot.  I’ve since ditched that config for simplicity.   The hardware and Arduino Sketch are still valid, so you can use those if you want to build one.  These instructions will show how to connect the hardware to a Flip32+...

How To: Install FrSky DHT 8CH DIY Kit into Turnigy 9x

Given the help provided by others, I thought I’ pay it forward with my spin on the installation of the FRSky DHT 8Ch DIY transmitter in my Turnigy 9x Transmitter.   Before getting into the details, I’d like to credit RCModelReviews for Bruce’s how-to video  as well as for details on how to update the firmware of the D4R-II (to solve the PPM framerate issue).   Although this is primarily about the DHT DIY module...
