Ever heard of the Indio Picaro doll? They are those kinda weird phallic statues, and they also happen to be a national joke in Chile. So hackers [Nathan] and [Pablo] decided to make use of its popularity for a hilarious drink serving robot (Translated) at this past weekends Santiago Mini Maker Faire.
Dubbed the PissCO, the bartending robot(s?) make use of eight Bartendro drink pumps, which is a system that was successfully funded on Kickstarter at the beginning of the year. Add some servos to make the little statues dance and swing around their… Anyway the whole system is probably one of the most unique cocktail mixing robots we’ve seen yet.
After all, who doesn’t want a drink served from a stainless steel basin that looks
vaguely like a urinal?
Stick around after the break to uh, see it in action.

Released in 1993, the Atari Jaguar suffered from a number of problems – it was difficult to program, had hardware idiosyncrasies, and with the CD drive was vastly overpriced compared to the Sega Saturn and Sony Playstation released one year later. Nevertheless, the Jaguar still has a rabid fanbase that counts [10p6] among them, and he’s created what Atari should have released 20 years ago.
In a few forum threads at jaguarsector (login required) and nexgam.de (no login, German), [10p6] goes over his changes to the classic Jaguar + CD combo. He’s stuffed everything inside a new case, cutting down on the amount of plastic from the old enclosure. A proper integrated power supply has been added, replacing the two power supplies used in the original. It’s also overclocked to 32 MHz, compared to the 26 MHz of the stock unit, making this a very powerful system that could have easily competed with the Saturn and Playstation.
[10p6] has an amazing piece of hardware on his hands here, and should he ever want to make a few molds of his new Jaguar, he could put together some sort of kit to replicate this build. He’s still working on finding a model maker and perfecting his case design, but a new, improved version of the Jaguar is something we’d love to see in a limited production.
[Damien George] just created Micro Python (Kickstarter alert!), a lean and fast implementation of the Python scripting language that is optimized to run on a microcontroller. It includes a complete parser, compiler, virtual machine, runtime system, garbage collector and was written from scratch. Micro Python currently supports 32-bit ARM processors like the STM32F405 (168MHz Cortex-M4, 1MB flash, 192KB ram) shown in the picture above and will be open source once the already successful campaign finishes. Running your python program is as simple as copying your file to the platform (detected as a mass storage device) and rebooting it. The official micro python board includes a micro SD card slot, 4 LEDs, a switch, a real-time clock, an accelerometer and has plenty of I/O pins to interface many peripherals. A nice video can be found on the campaign page and an interview with the project creator is embedded after the break.

Synth heads and electronic music aficionados the world over love a good rackmount synth. These days, though, synthesis tends more toward small, digital, and ‘retro’ rather than the monstrous hulking behemoths of the 60s and 70s. [gieskes] might be ahead of the curve, here, as he’s built a Game Boy module for his eurorack synthesizer.
The software running on [gieskes]’s Game Boy is the venerable Little Sound DJ (LSDJ), the last word in creating chiptunes on everyone’s favorite 8-bit handheld. As with any proper Game Boy used in chiptunes, there are a few modifications to the 1980s era hardware. [gieskes] tapped into the cartridge connector with a ‘repeat’ signal that provides slowed down, noisy signals for LSDJ. There’s also pitch control via CV, and the audio output is brought up to 10Vpp
In the video below, you can see [gieskes]’ euroboy in action with a few Doepfer synth modules. There’s also a very cool pulse generator made from an old hard drive in there, so it’s certainly worth the watch.

[Karl Lunt] has updated his Secure Digital Card locker to support password based locking. [Karl’s] original design only supported write locking via the TMP_WRITE_PROTECT bit. The new design gives the user an option: TMP_WRITE_PROTECT, or password protection. [Karl] goes into further detail this time around about the bit fields used with CMD42, and how they are set. The passwords in this case are up to 16 bytes. The bytes don’t necessarily have to be printable characters – any binary value can be used. Unfortunately, [Karl’s] locker doesn’t utilize a user interface beyond the buttons, so any password must be “baked in” to the SD Card locker firmware. We would love to see the option of even a basic serial interface for entering a password (most likely in hex).
[Karl] tried his device out with several different cards, and several computers. While not an exhaustive test, he did find that the computers always behaved the same: A locked SD card would not show up. In the case of windows, no beep, no drive, nothing. He goes into the security possibilities of using password locking: Financial data could be stored and physically transferred via SD or microSD, with the password sent separately (say in an email or SMS). Any unenlightened data thief attempting to use the card would think they have a broken device on their hands.
We don’t know how secure the password lock feature is – brute forcing a variable length 16 byte binary password would take some time. It all comes down to how quickly each password attempt takes. Some cursory web searching didn’t bring up any information about successful SD card password cracking. Sounds like a challenge for our readers!
From all the BSDs and Linuxes to extraordinarily odd operating systems, it seems just about every OS has been ported to the Raspberry Pi. All except Windows, that is, but a few people are working on it.
This build comes to us from [ideeman] who wanted to show off his Raspi running Windows Compact Embedded. It technically works, but there are still a few problems. In his own words:
Unfortunately, as it is now, I can’t really control it through anything else than via the kernel transport layer (through serial, directly to visual studio, and I still get lots of checksum errors, must me from the cheapo USB<==>TTL 3.3V adapter I’m using). The original developer (dboling) is still struggling with native USB drivers, but as you can see, he already got a (unaccelerated) running display driver.
If you’re interested, I can send you the compiled kernel image, but I don’t think you’ll do really much without the serial debugging provided through Visual Studio 2008 (+Platform builder 7.0)… I’m not sure it can be legally released to the public though.
While running Windows Compact Embedded isn’t as cool as running Windows RT on a Raspi, the latter will never happen. Windows RT requires 1 GB of RAM and a 1 GHz ARM v7 processor, neither of which the Pi has. Still, it’s a very impressive hack and with a few more devs on board, [dboling] and [ideeman] might end up with a truly functional system.
Below are pics of [ideeman]’s Raspi running WinCE. For [ideeman], feel free to link to a torrent in the comments.

[Ben], [David], [Drew], [Kayla], and [Peter] built a robotic artist as their senior design project. This mashes up a bunch of different project ideas, but the thing we like the most about it is that it works much like a photo booth that produces a painting. A Raspberry Pi uses a webcam to snap the picture, converts the image to three colors (plus the white background of the canvas) and sets the robot in motion. The team laments that initial testing of the completed project (seen in the clip below) worked out quite well but took hours to produce the painting. What do they expect? It’s art!
This is quite a bit different from the WaterColorBot (whose manufacturing process we just looked in on yesterday). WaterColorBot uses a flat canvas and a gantry system. This offering, which is called PICASSAU, uses an upright canvas with the paintbrush mounted in much the same way as a plotter robot. The biggest difference is that there is the ability to pivot the paint brush in order to pick up more paint, and for cleaning in between color changes.
