A Bit Distracted

A Bit Distracted

It’s funny how life seems to get in the way of hobbies. It’s a damn shame I can’t have a life of only hobbies. In any case, my family and I moved cross-country and then I became a stay-at-home dad. Unfortunately, it seems I am doing more work now than when I worked full time!? It also requires more of my attention. Who knew a two year old was this much trouble… …err.. …I mean fun. In any case, I’m…

Reflashing the Bootloader

Reflashing the Bootloader

When I first set-up Eclipse on Mac to allow me to do some debugging on my Crazyflie 2.0, I built and flashed a debug version of the firmware for the first time. The “debug” target in Eclipse creates a build with the parameter “CLOAD=0.” This means that the debug firmware is flashed at the start of the Crazyflie 2.0’s STM32 flash memory. This where the radio bootloader is normally written so, if one existed before flashing debug firmware, it doesn’t…

Set Up Eclipse for Debugging on Mac OS X

Set Up Eclipse for Debugging on Mac OS X

I recently got an ST-LINK/V2 JTAG debugger from Mouser.com so I can play around with hardware debugging on Crazyflie 2.0. To do this more easily, I figured I’d use the Eclipse IDE like the guys at Bitcraze do. Of course, I could use the <a href=”http://files.bitcraze.se/dl/Bitcraze_VM_0.6.ova” title=”Bitcraze 0.6 VM” rel=”nofollow” target=_blank”>Bitcraze 0.6 VM and all would be well and good… But, if you’ve followed this blog, you know I’d much rather do it all in Mac OS X. So, I…

Qi Inductive Charger

Qi Inductive Charger

My last post mentioned the next few posts would be about add-ons. In that context, here’s a post about something that makes the Crazyflie 2.0 much easier to use. One of the more useful items Bitcraze released with the Crazyflie 2.0 is an inductive charger Flykit* (Flykit is the formal name for the Crazyflie expansion boards). This little expansion is simply an inductive charging receiver coil with the requisite circuitry to allow it to inject 5V into the Crazyflie’s charging…

Blade Guard

Blade Guard

The next few entries will detail some add-ons I use with my Crazyflies to make them safer, easier to use, and more enjoyable. To that end, this entry is about blade guards. For the Crazyflie 1.0*, members of the Crazyflie community created 3D printable propeller guards that worked out well for those who have ready access to 3D printers. I cannot, unfortunately (yet), count myself among those people. So, for the entirety of the last six months that I’ve been…

Compiling Crazyflie 2.0 Firmware on Mac OS X

Compiling Crazyflie 2.0 Firmware on Mac OS X

UPDATE 2015-Aug-01: Bitcraze has recently merged the Crazyflie Nano (1.0) and Crazyflie 2.0 firmware source code. As a result, it is even easier to build firmware for either model on Mac OS X. See my article on the merge for more information on building the firmware. About six months ago I wrote a entry on compiling Crazyflie firmware with Mac OS X. Since that time, the Crazyflie 2.0 has come out and, as a result, compilation of firmware for the…

Crazyflie 2.0 Unbox

Crazyflie 2.0 Unbox

It finally arrived! My Crazyfie 2.0. The one “Christmas present to myself” that I’ve been waiting three months to receive! I won’t be posting an assembly entry for this Crazyflie. Seriously. It was too easy. So, without further ado, here’s the unboxing ceremony (two days before Christmas)…

New Arrival

New Arrival

I was growing impatient. Why didn’t I opt for a faster shipping service!? I just had to check the tracking once more… …and there it was: departed the sorting facility in my home town! A confirmation that the Crazyflie 2 is finally on it’s way to me., possibly in time for the holiday break, barring any mishap (oh please don’t let anything happen to it). The past few days have been torture! Watching the forums — all those lucky souls…

NeoPixel Ring Mod – Part 4

NeoPixel Ring Mod – Part 4

My last entry on the NeoPixel ring modification detailed how I “permanently” mounted the ring and the post before that was about how I got the firmware working like I wanted it. Prior to that, my first entry explained what I wanted to do and elaborated on some testing I conducted prior to deciding on what ring to use. This entry wraps my NeoPixel Ring mod up by exposing how I hacked in some controller support. The controller support was…

Broken, Then Fixed, On/Off Button…

Broken, Then Fixed, On/Off Button…

I’m man enough to admit it. I broke the on/off switch on my first Crazyflie. There, I said it. In my defense though, it didn’t seem to be that easy to push in the first place. It was sticky and didn’t move smoothly. I probably applied too much pressure and finally, the little plastic bit broke off. I denied it for a while. I was able to dismantle the button enough that I could simply use a straight pin to…
