The Little Charger That Could

The Little Charger That Could

I happened to be browsing Seeed Studio‘s site the other day after buying a cable and found a new product from Bitcraze that I hadn’t known about. It’s a tiny battery charger for spare Crazyflie batteries! This little gem is a 500mA charger based on the MCP73832 single-cell LiPo charge controller. It’s exceptionally small and works with the stock Crazyflie 2 batteries. One of the cool added features are the connection points you can use to solder multiple chargers together…

Decks

Decks

Deck is the official name of Crazyflie 2.0 expansion boards and now the variety of them is growing! At first, Bitcraze had only released a few decks, which I covered here on the Crazyflier blog. The LED ring is the most vibrant and flashy of them, followed by the functional and convenient Qi Charging deck. I didn’t write about the breakout deck for use with breadboards nor the prototype deck, which is perfect for modding projects. These two decks are…

Using Docker for Bitcraze Fun on Mac OS X

Using Docker for Bitcraze Fun on Mac OS X

Docker is the new hotness for Crazyflie development. The Bitcraze boys have a number of Docker VM images that can be used for everything from firmware builds to website editing! Pretty cool stuff. It takes a little setup though, and this is how to do it… Install the Docker Environment The easiest way to do this is to download the Docker Toolbox installer and run it. Keep in mind, you need to be running OS X 10.8 or later for…

Walkera Devo 7e Modding

Walkera Devo 7e Modding

Bitcraze did a great job when they implemented the Crazyflie system. With a Crazyflie and Crazyradio, a PC, and a game controller, anyone can get a mini-quadcopter flying. It’s an extensible system made of ubiquitous pieces. For what it’s worth, flying with a game controller is pretty good. Control is comfortable and easy to learn and the fidelity is high. But… What does a Crazyflier do when she wants more control or less system overhead or both? The answer is…

Stable Flight with an iPhone

Stable Flight with an iPhone

Some Crazyfliers seem to have trouble learning how to fly with the iPhone mobile client. I hope this entry can ease the learning curve for those people just new to the Crazyflie 2 who are using only a mobile client. This guide is written for iPhone (because that’s what I have and use) but most of it is probably applicable to Android as well. If you find it a little hard to learn how to control your Crazyflie 2 with…

FAA Drone Registration Requirement

FAA Drone Registration Requirement

As of tomorrow (21-Dec-2015), if you live in the United States and have a drone, you have to register it. The Federal Aviation Administration has created new statues governing private drone registration, likely to curb problems stemming from reckless drone pilots. Fortunately for us Crazyflie enthusiasts, the Crazyflie is exempt because the new law only requires registration if your drone weighs 250 grams or more (up to 55 pounds – then it is a different category). Of course, if you’re…

Crazyflie 2 Bundle on Massdrop

Crazyflie 2 Bundle on Massdrop

Massdrop has the Crazyflie 2 bundle available for the next 7 days. It’s a really good price for the quad and a few accessories. I’m going to pick up another Crazyflie 2 just for fun and hope Massdrop gets enough purchasers to make the $99 price! Even at the $109 price for 10 purchasers it’s a steal. I’d really like to see 20 purchasers though because $99 is an even sweeter bargain! It’s only available on Massdrop for another 7…

Flying on a Mac

Flying on a Mac

I’ve been out of the Crazyflie scene for a few months due to newfound (overwhelming) responsibilities as a dad and homeowner, but recently I came back because I had a few moments to spare. I’ve almost finished setting up my “workshop” in my new house and once I get my shop stool and soldering station put together, I’ll have more entries to make. But for now, I thought I should just get up and flying again.

Unified Firmware Source Code

Unified Firmware Source Code

In my last post on compiling Crazyflie firmware on Mac OS X, I mentioned that the band at Bitcraze had plans to eventually merge the Crazyflie 2.0 firmware source with the Crazyflie Nano (1.0) source on the master branch and now they have done it! Crazyflie Nano (1.0) and Crazyflie 2.0 firmware source code is now unified in the Bitcraze crazyflie-firmware GitHub repository on the “master” branch. This is really great news because it makes building for either (or both)…

Bitcraze LED Ring

Bitcraze LED Ring

A couple posts back I wrote a little about the Qi Inductive Charger as part of my posts on things that make the Crazyflie 2.0 safer, easier to use, and more enjoyable. This post is about an expansion deck that makes the Crazyflie 2.0 more enjoyable (if that’s even a possibility). One of the coolest, most attention getting, and fun expansion decks you can get for the Crazyflie 2 is the Bitcraze LED ring. This little device is a bottom…
