DIY & Hobby Projects: Parts, Components & Tools Must Have’s

Most people who visit to this site are either DIY’ers, Makers, Hackers, or Robotics / RC enthusiast.  For the most part, we all do the same thing – we build or mod stuff for our projects or hobbies.  Over the years, experience and repetition has given we wisdom as to what works, what doesn’t, and key components that I want to have on hand.  I wanted to share a list of parts/components I have found useful...

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...

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...

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...

Prop Storage Using LEGO Technic Axles

I have a variety of 5040 and 5030 spare props.  The need for both CW and CCW props, makes for a mess when trying to find a replacement when you crash and need a new prop. Given I break at least 1 prop per flight (I’m learning flips these days!), I wanted a quick way to access either size or direction of prop.   Look no further to your LEGO Technic collection for axles...

CubCadet CC500 Electric Mower – LiPo Battery Conversion

I decide to go the electric mower route about 5 years ago.  I was hesitant as the 12V lead-acid batteries most electric mowers come with suck – and they are heavy.  At that time, the only better technology was Lithium Ion battery-based mowers, but they were very expensive.  I decided on the CubCadet CC500, which was a good balance of quality and price. It was a 48 Volt lead-acid unit.

Quads: Why you need Failsafe and a LOMA

I finally got my 250-sized quad ready to fly.    The last 2 things I did were to add a LMOA (Lost Model Alarm) and configure failsafe in Cleanflight.  Luck was on my side yesterday as Murphy’s Law kicked in when I took the quad out for it’s first full flight test in a nearby field.   Admittedly, I still consider myself a noob with much to learn…  That said, I was flying FPV...

IoT Garage Door Monitor/Opener with Finger Print Scanner

I’ve got a lot of stuff in my garage, and having 3 kids (one of them being me!) with forgetful minds, the garage door is sometimes left open over night.  I don’t really like that sinking feeling after waking up the next day to find the door was left open.  Between loosing valuables and critters that make a mess of garbage, I finally decided it’s time to take a stance!  I have an IP Cam mounted inside...
