Traditionally, getting into the hobby of flying model aircraft required spending some serious coin, not to mention hours and hours of building and learning. All of that leading up to a white-knuckled, hair raising maiden flight. If you were extremely lucky, you’d head home with only a slightly damaged plane – but many of us did a nice death spiral straight into the ground – all just so we could go home, and then start all over. Perhaps one of the reasons we’re seeing so many (negative) drone related news stories recently is that the price of admission to join the club of flying machines has never been so low. That, and there always seems to be one kid in the class that wants to ruin it for the rest of us.
This year the FAA expects about a million people to wake up Christmas morning with a drone under the tree. And that’s a lot of chances for people to mess up. So if you’re planning on taking a drone up this year, you might want to watch the video after the break; Or just forward it to those that you think need to see it. If you’re into any sort of flying models you should already have [FliteTest] in your YouTube subscriptions – they have some really informative video, especially for the beginner wanting to get into the hobby.
This video guide is meant to be just a short introduction of what not to do. Obviously it doesn’t cover everything. And we wouldn’t be looking out for our readers if we didn’t say that your local laws may vary – so do your homework, stay safe, and don’t be a drone noob.

[JoshBaker] wanted to make something special for his brother this past Christmas. He decided on making a wooden game board version of the Settlers of Catan game. [Josh] used CorelDraw to construct the vector images needed for the board. Then, he set out cutting the base, engraving and cutting out the many wooden pieces with a laser cutter. All the pieces were stained and then sealed with polyurethane. He assembled the base so that the removable hex tiles, ports, and resource numbers sit nicely in the recessed parts and don’t shift during gameplay. He complemented the board with tokens and game pieces that he hand-painted. [Josh] also created a new set of cards to fit with the board’s aesthetic.
The board is done incredibly well, not to mention beautiful to look at. The hex tiles’ designs are very detailed. The stained and engraved wood really adds to the atmosphere of the game. We featured a coffee table that would be perfect to play it on. [Josh] has listed all of the vector files for the version he gave his brother, as well as additional ones for the Cities and Knights Expansion. We wish we could have seen the look on his brother’s face when he got such an awesome Christmas gift!
Have we seen any Christmas village hacks before? None come to mind and our Google-fu didn’t turn up any either. No matter, even if there were a handful this would rank quite high. [Kyle Anderson] built models of the homes each of his loved-ones inhabit. Each model lights up when its occupant is at home.
This reminds us of the Weasley Clock, itself a popular concept to hack on. The idea is that each family member’s location is shown with a unique clock hand and a set of whimsical locations on the clock face.
The Etherhouse, as [Kyle] calls it, performs a similar action. The WiFi access point in each loved one’s home is monitored for their smart phone. When it is detected, the light for their home model is illuminated. Since each person has their own copy of the village, everyone knows who is home and who is away.

We’ve seen capacitive touch organs manifest in pumpkin form. Though they are a neat idea, there’s something about groping a bunch of gourds that stirs a feeling of mild discomfort every time I play one. [mcreed] probably felt the same way and thus created this light-up Jello organ, so he can jiggle-slap Christmas carols, removing any sense of doubt that touching food to play music is weird…
This take on the capacitive tone producing instrument makes clever use of the transparent properties of Jello as well as its trademark wiggling. [mcreed] fills several small mold forms with festively colored strawberry and lime mix. One end of a wire connection is submerged in the liquid of each cup before it has a chance to solidify along with a bright LED. Once chilled and hardened, the gelatinous mass acts as a giant light emitting contact pad. An Arduino is the micro-controller used for the brain, assigning each Jello shape with a corresponding note. By holding onto a grounding wire and completing the acting circuit, one can play songs on the Jello by poking, spanking, or grazing the mounds.
Though I’m not entirely sure if the video is Jello propaganda or not, the idea is applaudable. I prompt anyone to come up with a more absurd item to use for a capacitive organ (zucchinis have already been done).

It’s that time of the year again, and the halls are being decked with trees, the trees covered in lights, and everyone working in retail is slowly going insane from Christmas songs piped over the PA. [Dan] has a tree and a bunch of programmable LEDs, but merely pumping jollity down that strip of LEDs wouldn’t be enough. The Nerd Quotient must be raised even higher with a tree that displays a Unix timestamp.
This build was inspired by an earlier, non-tree-based build that displays Unix time on a 32 LED array. That build used an ATMega328p for toggling LEDs on and off. This time around, [Dan] is using a dedicated LED controller – the AllPixel – that just wrapped up a very successful Kickstarter campaign. The AllPixel is, in turn, controlled by a Raspberry Pi running the BiblioPixel library,
The tree displays the current time stamp in binary across 32 spaces, with green representing a ‘one’ and a red representing ‘zero’. The top of the tree is the least significant bit, but in case [Dan] gets tired of the bottom of the tree staying completely still for the rest of this holiday season, he can switch the order making the base of the tree the LSB.

Thanksgiving was last week, and Christmas has been invading department stores for two or three months now, and that can only mean one thing: it’s time to kill a tree, set it up in your living room, and put a few hundred watts of lights on it. All those lights, though; it’s as if Christmas lights were specifically invented as fodder for standup comedians for two months out of the year. Why can’t someone invent wireless Christmas lights?
We don’t know if it’s been invented, but here’s a Kickstarter campaign that’s selling that same idea. It’s called Aura, and it’s exactly what it says on the tin: wireless Christmas lights, controllable with a smartphone. If it works, it’s a brilliant idea.

You know the holiday season is getting close when the Christmas light projects start rolling in! [Osprey22] is getting a jump on his holiday decorations with his Christmas Tree light show controlled by a Raspberry Pi. Yes, we know he could have done it with an Arduino, or a 555, but the Raspi makes for a convenient platform. With a WiFi module, code changes can be made remotely. The Raspberry Pi’s built-in audio interface also makes it easy to sync music to flashing lights, though we’d probably drop in a higher quality USB audio interface.
[Osprey22’s] Raspberry Pi is running his own custom python sequencer software. It takes an mp3 file and a sequence file as inputs, then runs the entire show. When the music isn’t playing, the Pi loops through a set of pre-defined scenes, changing once per minute.
The hardware itself is pretty straightforward. The Raspberry Pi controls 8 solid state relays through its GPIO interface. 8 strings of lights are more than enough for the average tree. [Osprey22] topped the tree off with a star made of wood and illuminated by a string of 25 WS2801 RGB LED pixels.
