The maker movement is made up of some 135 million adults in the U.S., however, it’s more than just a U.S. movement. Maker faires that celebrate the movement have popped up in Japan, Italy, Norway, and Chile. Makers use their skills to craft items such as clothing, baked goods, jewelry, and art; contributing $29 billion to the U.S. economy annually.

From 3D printers to laser cutters—makers employ various tools to create their goods. Many gather at makerspaces where they share these resources. Makerspaces are havens for techies, artists, and entrepreneurs. Through crowdfunding, makers are able to facilitate small-scale funding for these gathering spaces.

A DIY dynamic electronic load by Jay_Diddy_B over at EEVblog Forum:

The dynamic load steps the load current so that the transient response of the power supply being tested can be observed.
Features:
0-5A maximum continuous current
0-5A pulsed current at 330Hz

edison_breakout

by Stephen Edward:

A Simple Breakout board for the edison. Does nothing special except breaks out the 70pin connector to 2.54mm Pins so you can start experimenting with the Edison.

Has an experimenters area so you can solder on things like a regulator or Level shifter.

It also has the bottom side through connectors so that you can daisy change multiple boards or other Edison shields

F7YSIM6HMEXSYX5-600x401

ajoyraman posted a tutorial on how to make a DIY USB-matchbox oscilloscope, an instructable here:

In order to economize on the cost of an enclosure while still providing an aesthetic unit the Aj_Scope2 is enclosed in a large size cardboard matchbox enclosure.
The USB connection to the PC is on one end while the Audio-Jack for the signals to be monitored is on the other.
A ‘Busy’ LED is provided on one corner at the top and a ‘Reset’ switch is provided diagonally opposite.
The ‘Reset’ switch provides a restart of the micro-controller is the worst-case of hang-up. This typically occurs when the operator selects a trigger threshold which is out of limits with respect to the waveform being observed. If the Aj_Scope2 is operated correctly this switch is seldom used.

makerspaces-001

by Morgana Matus:

Since the first wheels of mass production started turning during the Industrial Revolution, fine craftsmen and DIYers have found it more difficult to sustain their crafts. Until recently, those handmade-focused entrepreneurs who wanted or needed access to the latest technology would have to assemble a large amount of capital for items such as 3D printers or CNC machines. Those who couldn’t afford the high overhead were left to envy those wares and hope for a price decrease.

Gobo Stereo Audio Amplifier Kit (LM1875, 15W, Class-AB)

Gobo-LM1875-Stereo-Amplifier-Kit

by Giovanni Militano @ diyaudioprojects.com:

I’ve always enjoyed electronic kits of all kind and like many of you will credit them for the foray into DIY audio. Over time as my DIY skills matured I found myself taking the DIY route for projects far more often than relying on kits. While I will always enjoy electronic kits, I generally won’t try one out unless there is something really unique about the kit. When I saw the Gobo Stereo Audio Amplifier kit from boxedkitamps.com, I was immediately intrigued by the unique looking enclosures available with the amplifier kits. Shown in Photograph 1 below is the completed Gobo Stereo Audio Amplifier kit with a translucent blue acrylic enclosure. The choice of enclosure finishes for the Gobo stereo amplifier kit include blue, dark grey and orange acrylic and bamboo.

pulseoximeter

Pulse oximetry is a non-invasive method for monitoring if a patient’s oxygenation is unstable and Arduino user die_Diode sent us his version of a DIY Pulsoximter developed with two Arduino:

Arduino Mega for the oximetry electronics and Arduino Uno for the graph. The electronics includes LED Driver, Photo current transformation, patient-dependent calibration LED, Active filters, Nellcor SpO2 sensor. Adafruit OLED displays Vitalparamter. Noritake VFD display GUU-100 shows the PPG. The boards are connected to the electronics with a Protoshield.
