Well, it’s the holiday season! Which means two things. Long, sometimes uncomfortable gatherings with family, and our favorite — free time. So if you’re looking to catch up on some movies, [Rajesh Verma] has you covered. He’s compiled a database that aggregated data from both Rotten Tomatoes and IMDB!
That means you can very easily sort through based on critic’s favorite, audience favorite, IMDB favorite, underrated, overrated, year, etc. He started by dabbling with aggregation scripts with just Rotten Tomatoes, and after he released one showing both Audience and Critic scores, Rotten Tomatoes updated their site to include that sorting method! Coincidence? Maybe.
Either way, it broke his original script when the site was updated — so he’s come back with something even better — a list for both IMDB and Rotten Tomatoes.
He started the project thanks to [Michael] at Meta Film List, who had the idea of making movie databases more accessible. Without further ado, you can check out the list on Google Docs.
[Macaulay Culkin] err… [Kevin McCallister] pulled off some epic 1990 hacks to scare off a couple of bumbling burglars in the classic film Home Alone. Now celebrating its 25th Anniversary, it’s fun to see the tricks [Kevin] used to spoof a house party brought into this age of high-technology.
The trick in the original movie was all about silhouettes in the windows that made the house look full of people. [Michael Jordan’s] cardboard cutout taped to a model train is fairly believable. But really, who has a half-dozen mannequins just sitting in their attic? Creepy.
The marketing company RedPepper are behind the facelift of this pop culture icon. They outfitted their offices with some window dressings that are perfect for the silhouettes. In a delightful cyberpunk twist they went with projects and digital silhouettes. Embracing our current tech-heavy lives is the mobile aspect of it all. Of course there’s an app for that. It means [Kevin] doesn’t have to pull the strings. He can hide outside the building and decide which animations are played by the projectors within. Check it out after the break.

Liberty Games in the UK was looking for a fun way to support charity for the holidays, and we think they succeeded. They decided to set up an arcade crane machine to run over the internet, with each type of toy snagged earning a donation. Snag a bear, and they will donate £5 to St Mungos, a UK charity that works with homeless or at risk people. Snag one of the rarer Santa toys, and they will donate £20. It’s a great cause, and a nice hack. Behind the scenes, the Internet side of things runs on a Raspberry Pi connected to a PiRack and a couple of PiFace digital interface cards that are wired into the electronics of the crane machine so they could control the buttons on the machine from a Web interface. Unfortunately, it didn’t seem to be running when we tried it, but hopefully someone will give the machine a swift kick shortly to get it going until the Hackaday traffic invariably brings it down again.
One of the interesting thing that they discovered while working on these hacks: they have a pay-out ratio that is determined by the strength of the grabbing arm. The owner can tweak this so that the arm does not grab very firmly, which means a dropped bear. Want to torture your friends with hopes of snagging the best stuffed animals?. Follow the example of this claw machine build all from parts on hand.
[theKylenator] spent about a month building this brilliant Halloween costume for his son. We realize its almost the holidays, but this is just too darn awesome not to share, despite being a bit late for our standard Halloween hacks.
Made completely out of cardboard, it just goes to show you really can make some awesome hacks that aren’t expensive — or overly complicated.
While the baby appears rather indifferent in possessing a suit capable of mass destruction, the wife filming the video sounds ever so impressed too: “It’s pretty cool babe.”
[Kyle] on the other hand is having the time of his life. Just listen to the mechwarrior sound effects he makes.

When [hkdcsf] was a teenager, he made a Christmas star with an up counter driving decoder logic and using transistors to light LEDs in festive patterns. He’s revisited this project using modern techniques including a microcontroller, a DC/DC converter, and constant current LED drivers.
The project uses two AA batteries, and that’s what makes the DC/DC converter necessary. Blue LEDs have a forward voltage of just over 3V, and the LED driver chip requires about 0.6V of overhead. Two fresh AAs will run a tad above 3V, but as they discharge, or if he’s using rechargeables, there just won’t be enough potential. To make sure the star works even with whatever LEDs are chosen, the converter takes the nominal 3V from the batteries and converts it to 3.71V.

[Conor] wired up his 3D-printed coffin doorbell to an array of RGB LEDs, a screaming speaker, and a spinning skull on a cordless screw driver to make a “quick” Halloween scare. Along the way, he included half of the Adafruit module catalog, a relay circuit board, and ESP8266 WiFi module, a Banana Pi, and more Arduinos of varying shapes and sizes than you could shake a stick at.
Our head spins, not unlike [Conor]’s screaming skull, just reading through this Rube Goldbergy arrangement. (We’re sure that’s half the fun for the builder!) Smoke ’em if ya got ’em!
Start with the RGB LEDs; rather than control them directly, [Conor] connected them to a WiFi-enabled strip controller. Great, now he can control the strip over the airwaves. But the control protocol was closed, so he spent a week learning Wireshark to sniff the network data, and then wrote a Bash script to send the relevant UDP packets to turn on the lights. But that was not fancy-schmancy enough, so [Conor] re-wrote the script in Go.
Yes, that’s right — a Go routine on a Banana Pi sends out custom UDP packets over WiFi to a WiFi-to-LED-driver bridge. To make lights blink. Wait until you see the skull.
The plastic skull has Neopixels in each ping-pong ball eye, controlled by an Arduino Nano and battery taped to the skull’s head. The skull is cemented to a driver bit that’s chucked in a cordless drill. A relay board and another Arduino make it trigger for 10 seconds at a time when the doorbell rings. Finally (wait for it!) an Arduino connected to the doorbell gives the signal, and sets a wire high that all the other Arduini and the Banana Pi are connected to.
Gentle Hackaday reader, now is not the time for “I could do that with a 555 and some chewing gum.” Now is the time to revel in the sheer hackery of it all. Because Halloween’s over, and we’re sure that [Conor] has unplugged all of the breadboards and Arduini and put them to use in his next project. And now he knows a thing or two about sniffing UDP packets.

There’s something about lawn mowers and hackers. A desire to make them into smart, independent robots. Probably in preparation for the day when Skynet becomes self-aware or the Borg collective comes along to assimilate them into the hive. [Ostafichuk] wanted his to be ready when that happens, so he’s building a Raspberry-Pi powered, Dalek costumed Lawn Mower that is still a work in progress since starting on it in 2014. According to him, “commercial robot lawn mowers are too expensive and not nearly terrifying enough to be any fun, so I guess I will just have to build something myself…”
His first report describes the basic skeletal structure he built using scrap pieces of wood. Two large lawn tractor wheels and a third pivot wheel help with locomotion. The two large wheels are driven by geared motors originally meant for car seat height adjustments. A deep cycle 12V battery, and solar panels for charging would take care of power. A raspberry-pi provides the brain power for the Dalek-Mower and L298N based drivers help drive the motors. The body was built from some more planks of scrap wood that he had lying around. While waiting around for several parts to arrive – ultrasonic sensors, accelerometer, 5V power supply modules – he started to paint and decorate the wood work. Generous amounts of water repellent paint and duct tape were used to make it weather proof. His initial plan was to use python for the code, but he later switched to programming in c along with wiringPi library. Code for the project is available from his bitbucket git repository. Load testing revealed that the L298N drivers were not suitable for the high current drawn by the motors, so he changed over to relays to drive them.
