If you are into audio electronic projects have a look at this ECC802S Shunt Regulated Push-Pull Tube Preamplifier. One thing about these tube amp builds is that the housing looks just as nice as the circuit construction.

Thanks Gio.

“After the success with the various Odd Block amplifiers that used a SRPP (shunt-regulated PP) driver stage I started to do some research and modeling on a SRPP. The advantages of such a line stage are much the same as those when a SRPP is used as a driver. Good linearity, low distortion, low impedance output, good power supply noise rejection and modest gain.”

If you have one of these View-Masters you might want to bring it into the modern day, have a look at this LCD Screen Hacked View-Master by Hackerconsortium.

Thanks Tuttle

“Long gone are the days of light shining through celluloid images on a disk… Long gone! Why this little feller here has Two, count them, 2 Colby 1.5 inch digital key chain picture frames lined up with each lens to create a digital stereoscope. Wait there’s more don’t go. What more you ask? Well this little device actually comes pretty damn close to doing stereoscope really well. It even surprised me!”

Propeller Clock Build

at 6:50 pm. Filed under Complex Hacks, Computer Hacks, Electronic Hacks


This is one very cool looking Propeller Clock Build! It is based on the ATmega324P and was programmed in BASCOM-AVR. There is more information in this forum post (translator needed). Unlike my Spinning Display project this one does not have wire connections to power the rotating section instead it uses induction to power the spinning section.

Thanks for the tip Muris.

High Voltage Washer Launcher

at 6:12 pm. Filed under Complex Hacks, Crazy Hacks, DIY Hacks, Electronic Hacks, Insane Equipment, What Were They Thinking


Our good friend Bob Davis has been doing some more high voltage tinkering. He has been working on another High Voltage Washer Launcher, this is a new and improved version of some of his past high voltage projects. If you are just looking for some explosive fun have a look at 4:35 and 5:45. I love the use of the safety broom. 🙂

“My old 8 capacitor power supply is back in action!  This time it has 10 capacitors, and delivers 2000 volts at 1600 amps from 1,600 uF of capacitors in a series/parallel combination.  The old 5 watt resistor was replaced with a 50 watt resistor!  It still smoked when it was powered on likely from grease from my fingers.”

How to take good Pictures of Electronic Projects

Funny that Johngineer comes out with his tutorial about How to take Pictures of Electronic Projects now. I just got my photo cube in the mail yesterday. I will be setting it up in a somewhat permanent photography location soon, I can’t wait to use some of these tips to see how I can make my pictures look better. I have been talking with our friend Daniel Garcia from Protostack who has always taken fantastic looking pictures of his projects! He uses a cube and normally shoots outside in natural light. I have already purchased some Daylight compact florescent bulbs so we will see how good they look. I am looking forward to the long learning curve.

“A cyclorama is a surface that provides you with a uniform background. A cyclorama (also called a cyc, rhymes with “bike”) can vary in size from a tabletop (such as this one) to a warehouse (used for cars and other large objects). It’s really nothing more than a concave surface of uniform texture — it’s horizontally flat in the front and curves up to vertical in the background. The one we’re going to build here uses a lightweight frame of PVC pipe and a sheet of poster board, along with a few thin panels of MDF for extra rigidity. It costs about $20 in parts. If you are using a table that sits up against a wall, you can skip the PVC frame and simply tape the poster board to the wall and table in the appropriate shape. However, you may find the PVC frame gives you more flexibility because you can move around it.”

SixthSense – Gesture Controlled Computing Device

Amit Pate, a graduate of Computer Science from Vishveshwarya Technological University developed SixthSense which is a Gesture Controlled Computing Device. We have seen similar Gesture Controlled Devices before, with the cost being only around $300 this could be something we see commercialized in the near future.

Via: HG Comments

“In a simple way, a gesture-controlled wearable computing device that feeds you relevant information and turns any surface into an interactive display. Called the Sixth Sense.

Basically, this is a mini-projector coupled with a camera and a cellphone—which acts as the computer and your connection to the Cloud, all the information stored on the web. There are four different coloured caps that act as cursors to the system. The camera recognizes objects around us instantly, with the micro-projector overlaying the information on any surface, including the object itself or your hand.

The software program processes the video stream data captured by the camera and tracks the locations of the colored markers at the tip of the user’s fingers using simple computer-vision techniques. Then, you can access or manipulate the information using your fingers. It also supports multi touch and multi user interaction.”

Zippo Burglar Alarm

pocket-burglar-alarm


Ever wanted to have a alarm system that could fit into your pocket? Well have a look at this Zippo Burglar Alarm, it’s pocket sized since all the electronics are stuffed into a Zippo lighter. It is based around a Picaxe microcontroller which controls a few IR LEDs and monitors an IR Receiver module. The alarm is a piezo buzzer which is also mounted in the tiny case.

“It works by sending out a modulated infrared signal. The detector then senses any of the reflected signal, this is how it knows if anyone has passed by. The main board contains a pickaxe chip. There is a mode select button which allows you to cycle through the different detection methods and alerts. It runs off of 3 x AG-13 button cells and can sense up to 15cm+ in good conditions.”
