Just for fun, Eye Catching LCD Video Glasses


While you may think that the glasses shown below would be rather expensive, you can actually make them for less than $15.  It’s as simple as buying two small digital photo frames on eBay for $6 and sacrifice an old pair of glasses.  Of course, you can’t see out of them


The overall idea is pretty absurd and I can’t believe I’m posting something related to Lady Gaga on HacknMod.  Nonetheless, the use of cheap LCDs is still pretty unique. The project is simple enough – the only critical components are the cheap digital photo frames. Just be sure that the digital frames fit into the glasses frames.

Incredible DIY Daft Punk Helmet Project

We’ve covered some downright superb daft punk projects in the past, but this helmet is one of the best so far. It took 17 long months to build and was documented fairly well in the project’s build notes.  The video below is a great walkthrough of the build as well.

The helmet is shaped from resin, finished with chrome, and illuminated with LEDs. The rainbow illumination effect is a result of LEDs housed in a pattern around the shape of the helmet. An Arduino, AA batteries, and potentiometers help to control the lighting and are attached externally to the Daft Punk helmet.

17 months seems like an absurdly long time, but consider the entire build process including molding, casting, sculpting, painting, and electronic wizardry that went into it.  Worth it?  If you’re a die hard fan.  Otherwise, we’ll stick with some less time intensive daft punk projects.

Ramps 1.4 + A4988 + Mega2560 R3 + Endstop + Cooler Fan Kit For

RepRap 3D Printer

This is the new SainSmart 3D Printer  Starter Kit, developed specially for those beginners who are interested in 3D printer.  You will have a complete set of SainSmart’s most common and useful electronic components. What’s more. We will offer you a detailed tutorials including project introduction and their source codes.You may learn about Sainsmart through using these basic projects.


1.Sainsmart RAMPS 1.4
It is a Mega Pololu Shield, or RAMPS for short,designed to fit the entire electronics needed for a RepRap in one small package for low cost. RAMPS interfaces an Arduino Mega with the powerful Arduino MEGA platform and has plenty room for expansion. The modular design includes plug in stepper drivers and extruder control electronics on an Arduino MEGA shield for easy service, part replacement, upgrade-ability and expansion. Additionally, a number of Arduino expansion boards can be added to the system as long as the main RAMPS board is kept to the top of the stack. This board is mostly based on Adrian’s Pololu_Electronics and work by Tonok. Copper etch resists methods suggested by Vik. Also inspired by Vik’s work with EasyDrivers. circuit design based mostly on Adrian’s Pololu_Electronics Joaz at supplied initial pin definitions and many design improvements. Much inspiration, suggestions, and ideas from Prusajr, Kliment, Maxbots, Rick, and many others in the RepRap community.

2. Sainsmart Mega 2560 R3
Sainsmart Mega2560 R3 is an ATmega2560 as core microcontroller development board itself has 54 groups digital I / O input / output terminal (14 groups do PWM outputs), 16 sets of simulation than the input side, group 4 UARTs (hardware serial ports), using the 16 MHz crystal oscillator. With the bootloader, download the program directly via USB without having to go through other external writer. Supply part of the optional USB power, or as an external power using the AC-to-DC adapter and battery. Arduino development IDE interface is based on open-source principles, allows you to free download for use in project work, school teaching, motor control, interactive works.

3. Sainsmart A4988 driver
This product is a carrier board or breakout board for Allegro’s A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection by Pololu; we therefore recommend careful reading of the A4988 datasheet before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2 A output current per coil.


4.SainSmart Mechanical Endstop Switch

The mechanical endstop is a simple solution to a simple problem. We want to be able to detect when an X/Y/Z stage has reached its minimum or maximum. Instead of messing with flags or complicated light beam interruptors, we use a mechanical switch. If we place the switch in the path of the stage, then the stage itself will simply close the switch when it moves against it. Other than properly positioning the switch, we do not need to modify the stage at all. If you’re worried about reliability, you can sleep well at night. The switches we use are rated for 1 million operations before failure. Since we only use the switches once per print, that means you’ll be able to do one million prints before having to replace the switch.


5.SainSmart 2004 Smart Yellow LCD Controller With Adapter

This Smart Controller contains a SD-Card reader, an rotary encoder and a 20 Character x 4 Line Yellow LCD display. You can easy connect it to your Ramps board using the “smart adapter” included.
After connecting this panel to your Ramps you don’t need your pc any more, the Smart Controller supplies power for your SD card. Further more all actions like calibration, axes movements can be done by just using the rotary encoder on the Smart Controller. Print your 3D designs without PC, just with a g-code design stored on the SD card.

Project-SainSmart 3D printer built

The article is a person named Garrett Kendrick who used sainsmart 3D ptinter board to build his own 3D printer. Check out the process of this project.

Part 1

I have wanted a 3D printer for many years and done a lot of research. My first 3D printer was an Ord Bot Hadron that I purchased online for over $1500. While I love this printer design and high accuracy, I had a hard time shelling out that amount of money. I’m very happy with the printer, but wanted to find a way to make another (better) version for a much reduced price. That lead me to this build.


I received the SainSmart RAMPS 1.4+Mega 2560 R3 3D Print Kit. This kit includes the Arduino Mega 2560 microcontroller, Sainsmart A4988 driver board, 5 Sainsmart RAMPS 1.4, and plenty of interconnecting cables in a nice case. For the price, I was sceptical, but once it arrived (within 2 days of ordering) I was impressed.

I also received the SainSmart 1.75mm green ABS filament.

I found a good deal ($430) on an Ord Bot Hadron mechanical frame with orange accessories on eBay and bought it.

Part 2

I began printing the printable parts for my new printer with my old printer using the SainSmart green ABS. The parts came out beautifully!

Can a 3D printer print a 3D printer?


A starfish can reproduce without a partner. The creature loses an arm, and before you know it, you have another starfish. Think of the potential for the species to take over the world, if enough of them were willing to make that initial sacrifice of a limb.

Are 3D printers the starfish of the technology world? That is, can a 3D printer print a 3D printer? And if so, do we need to fear a runaway scenario? An attack of the killer 3D printers, if you will.

I did a little research (emphasis on word little) this morning, to see if I could find any examples of such self-replication; of an incipient master race of mechanical self-maters.

Nothing. Phew!

But surely, it must be happening. The hype of 3D printing has the things making just about everything else. We’ve all heard about the gun they can fabricate. And according to AskMen’s highly entertaining but somewhat questionable 3D Printers: 50 Things You Can Make, they can churn out meat, stem cells, jawbones, camera lenses, dishwasher parts, guitars, houses and even a Stradivarius violin.

So I return to my question. Can a 3D printer print a 3D printer? And what if one of these contraptions also started spawning not only more of itself, but starfish as well?

I’m frightened. I think I’m going to print a spaceship and flee to Mars. It might be a bleak existence – there’s no Twitter there that I know of. But at least there won’t be any 3D printers either. Not yet, anyway.

Hey! Catch up the Leaders Of The 3D Printing Revolution


How to Create a Dedicated Pandora Radio Streamer

Everyone loves Pandora, but let’s face it: it’s a shame to leave a PC on for the sole purpose of streaming music .  You can buy various devices which come “Pandora ready” such as AV receivers, Roku, and Xbox OR…you can have the satisfaction of building your own using a Raspberry Pi!

As you’re likely aware, the Raspberry Pi is a competent, credit-card sized Linux PC.  All you need to build your own “Pandora’s Box” is a Raspberry Pi, LCD, and a few switches (for controlling the music).  Ready to build your own?  Learn how using these step-by-step instructions.

Time to meet the 3D printing works

Amazing!! DIY Furniture from Recycled Circuit Boards

They may appear to be a monstrous mess from a distance, but look closely and you’ll see the extreme detail in this project.  The Binary furniture collection is as new age you can get; or as geeky.   All three were made from pieces of salvaged electronics: everything from ethernet cables and PCBs. For instance, the inner skeleton of the Binary Table (above) is made from computer case metal and the surface is motherboards, LCD screens, and hard drives.

  • The Binary Chairs have cushion cover weaved from wire (see below), typically stripped Ethernet cables, in a slightly random but colorful mosaic configuration. The hard drive disks can be spun, the telephone keys and other buttons can be pressed, and the antennae raised and adjusted.
