Electric paint brush loads itself with paint

Meet [Jahangir Ahmad]. He’s a 19-year-old from India who recently won third place in a contest put on by the National Innovation Foundation. Here he’s posing with the electric paint brush which he developed after seeing some local painters struggling with brushes and buckets at the top of a ladder.

His system uses a 1 hp motor to pump paint from the bucket directly into the brush. Once it enters the handle a distributor splits the flow into four parts so that it reaches the bristles evenly. The pump of the paint is actuated by a controller which can be worn on the painter’s belt. When you get a little low on paint, just hit the button and you’ll get boost. Since the base of the bristles is meant to hold a small reservoir of paint, this has the potential to be better than dipping in a bucket.

Android 4.0 on Raspberry Pi

The folks over at the Raspberry Pi foundation are showing off their latest wares. This time around it’s Android 4.0 running on the Raspberry Pi. Although this is a pre-release announcement, it sounds like the work is rather far along. Hardware acceleration for video playback is in place, but there are still some audio issues that need to be fixed before it will be ready.

We know the foundation isn’t the first one to pull this kind of thing off. Look around and you can see some other proof-of-concept videos which show Ice Cream Sandwich running on the board in one stage or another. But the demo from the video after the break gives us hope that rock solid support is just around the corner. After all, Netflix runs on Android and so does XBMC. Both running on the RPi brings the device one step closer to the holy grail of dirt cheap and mostly-open set top boxes. The one thing we haven’t seen yet is the killer control method for the device. If you’ve got one up your sleeve you should post some details and send us the link.

Never miss a roadside photo-op with an easy camera hack.

When you’re driving for days on the highway, you see some interesting things. If you’re like me, you usually don’t have the time to get your camera out and snap a picture. Especially if it is just a goofy looking car, or an interesting tree or something. This hack will make it really easy to get pictures of sights on the highway by allowing you to snap a picture at the press of a button.

Hacking the computer interface of a Ford Focus Mk2

You can do some neat stuff to the way your Ford Focus Mk2 works, but first you have to gain access to the data system. If you know some Russian, and don’t mind a bit of dongle rewiring, this guide will have you hacking the car’s CAN bus in no time. It was written by [Preee] and he has already added Radio RDS and CD Track information to the speedometer display panel, implemented hands free control for his cellphone, disabled the sounds the car makes when he goes into reverse, changed the door locking speed from 5mph to 10mph, and much more.

To gain access to the system you need hardware to bridge from a computer to the CAN bus. He hit eBay and bought an ELM327 cable which plugs into the On-Board Diagnostics port (ODBII). There are two different ways these dongles can be configured and since this isn’t the right one for the Focus he had to alter it. His hardware changes are illustrated in the second post of the forum thread. Instead of just switching over to the other configuration, he wired up a toggle switch to select between the two.

With hardware in place he grabbed some software and started hacking away. But as we hinted above, it’s not as simple as you might think. The software is in Russian. [Preee] did his best to add translations to a few screenshots, but it’s still going to be a bit of a bother trying to find your way around the GUI.

Digital TV converter reverse engineering

Back when broadcast television was first switching over from analog to digital most people needed to get a converter box to watch DTV broadcasts. Remember that abomination that was “HD-Ready”? Those TVs could display an HD signal, but didn’t actually have a digital tuner in them. Nowadays all TVs come with one, so [Craig] found his old converter box was just gathering dust. So he cracked it open and reverse engineered how the DTV hardware works.

The hardware includes a Thompson TV tuner, IR receiver for the remote control, and the supporting components for an LGDT1111 SoC. This is an LG chip and after a little searching [Craig] got his hands on a block diagram that gave him a starting place for his exploration. The maker of the converter box was also nice enough to include a pin header for the UART. It’s populated and even has the pins labeled on the silk screen. We wish all hardware producers could be so kind. He proceeds to pull all the information he can through the terminal. This includes a dump of the bootloader, readout of the IR codes, and much more.

Hackaday has won 1st place in the RedBull Creation contest!

The people have spoken. Hackaday has won the Redbull creation challenge by popular vote.  Despite a few bumpy spots in the voting process, our project, the Minotaur’s Revenge (gameplay footage around the 2min mark in the video), got the most votes from the public winning us $5000 for our hackerspace and a trip to the World MakerFaire in New York.

Thanks to everyone who was able to actually vote, and we totally understand about those who didn’t.

OLinuXino booting Android

We can’t say the name rolls off the tongue, but it is beginning to look like the OlinuXino is going to happen. Here you can see the prototype hardware booting Android. If this is the first time you’re seeing the hardware you can think of it in the same category as the Raspberry Pi. It’s a butt-kicking ARM platform that comes as a bare-board with which you can do what you please.

Olimex Ltd. put together the offering, which seems to be part of the name mash-up (Olimex + Linux + Arduino?). The board hosts an ARM Cortex-A8 processor which runs at 1 GHz. There’s a half a gigabyte of ram, four USB and one USB-OTG ports, and a big array of breakout pins. One eyebrow-raising choice was not to include an HDMI connector. Instead the board offers VGA and Audio outputs. There is a pin header meant for an LCD screen, as seen in the image above, so it could be that the intention here is for smaller or more portable applications. But like we said, the form factor really lets you do what you want.

Possibly the best part is the price. The target for the top-of-the-line board is 55 Euros (about $68) and that comes with WiFi and 4 GB of NAND storage on the board. There’s a bunch of posts on the project, including a look at the PCB routing work. This link to the A13 tag will give you the widest overview of the work so far.
