Alien Motorcycle made from Scrap Metal

at 5:14 am. Filed under Insane Equipment


This Recycled Alien Bike is certainly one that you will not find in your local bike dealership. It was made entirely from scrap metal by Bangkok artist Roongrojna Sangwongprisarn. It reminds me of the crazy Skull Bike we saw back in 2006.

Via: UniqueDaily

“Roongrojna Sangwongprisarn, 54, created it out of spare parts in his workshop in Thailand. He has four shops across the country – named the Ko Art Shop – and exports his creations to clients all over the world.”

Talking Robot Mouth

at 5:20 am. Filed under Educational, Insane Equipment, What Were They Thinking


This Talking Robot Mouth looks a bit creepy but works amazingly well. This robotic mouth is making sounds the same way we do. The mouth is made of various silicone materials blended together and the nose has the same function ours does when it comes to the creation of human vocals. The most impressive thing is that the robot learns as it talks, there is a microphone which allows the system to listen to hear the output so it can make modifications to future speech.

“We’ve given the robot the score for the song Kagome, kagome. It’s already learned how to make the sound “ka,” and it’ll retrieve that information from its brain. The robot’s also learned how to change a sound’s pitch by changing the air flow, so it’ll retrieve that data. In other words, it’ll use the information already in its brain to make sounds, while estimating speech movements based on the score. So all we are giving it is the words and the pitch.”

RobotGrrl makes an iPad app control RoboBrrd using a Redpark Serial Cable

at 10:49 pm. Filed under DIY Hacks, Electronic Hacks, Toy Hacks


RobotGrrl (Erin Kennedy) has been working on RoboBrrd for a long time, she has now made an iPad app which lets you feed the bird various fruits, the app communicates with the bird via a Redpark serial cable. The on-board Arduino deciphers the commands to perform the appropriate actions such as flapping its wings or chewing on the fruit. The Redpark cable comes with an iOS SDK which allows the developer to use the serial cable in no time. Erin shows us how she wrote the iPad and Arduino code in the second half of the video.

CNC Halftone Pictures

at 5:38 am. Filed under DIY Hacks


Metalfusion from Finland has developed an interesting method of creating CNC routed halftone images using a single v-bit router bit. Just like a news paper prints images using dots of ink this process produces dots of different sizes by plunging the v-bit to varying depths. He has developed the software which allows normal images to be converted into files that are ready to be cut on a CNC machine. It isn’t a quick process though for example the apple image is recreated with 3774 individual dots.

3D Color Printing

at 2:53 pm. Filed under Cool Gadgets

3D printing no longer seems to have the wow factor that it did a few years ago, I remember how crazy it seemed a year and a half ago when when Bradley Rigdon demonstrated how to print a 3D bearing. Most of us have now seen something that has been printed in a 3D printer. This is thanks in large part to the MakerBot which has brought inexpensive 3D printing to the masses. Ponoko who has sponsored one of our contests in the past is offering color 3D printing with some impressive results. They have featured an interesting video that was done for National Geographic which was produced to make the technology seem even more magical than it is. I am sure that you will catch the issues that are smoothed over in the apparent recreation of the wrench in the above video. I was thinking that the scanner was some magical creation or there was about 5 hours of time that lapsed between scanning and printing so they could make the scan work. Watch the video below for the truth in what happened in the creation of the tool. If you are curious what Bradley Rigdon from Print to 3D is up to have a look at the 3rd video where he demonstrates the 3D transmission he is making.

AM Broadcast Band Rejection Filter for Shortwave Reception

at 5:36 pm. Filed under DIY Hacks, Electronic Hacks


Greg from Electronicsnerd will be building some RF projects over the next few days. Today he presents an AM Broadcast Band Rejection Filter for Shortwave Reception which is based on the work of Joseph J. Carr. You can find the circuit in this article (PDF). With only 7 components it’s a simple circuit that could be built in a short time.

“With an eye toward proper RF construction techniques, I kept lead lengths short and the components in a line from input to output. The SparkFun board I used doesn’t have huge traces (which at RF tend to perform like little antennas) and I’m happy with the clean build. The best way to construct this would have been on a nice copper ground plane, but I wanted to pop this together in an hour and see if it worked. Next I’ll put the filter in a nice metal box with overlapping edges. The finished product will sit between a long-wire antenna and the G3′s external antenna input.”
