This is a relatively inexpensive and easy to build project that will help you test out all of your Arduino projects and prototypes. Since it has a plug-in power source, it eliminates frequent battery use and leaves the breadboard free of voltage regulators and capacitors providing more room for projects. However, if you need battery power instead, the Prototyping Center also has the option of switching to 9 volts of battery power. Additionally, this prototyping center will have room for a soldering iron and "Third Hand" soldering tool so everything you need will be at your fingertips. The Prototyping Center will give you access to chose from 9 volts, 5 volts (perfect for Arduino prototyping), and 3.3 volts. 

A soldering Iron, cordless drill, coping saw, wood glue, hot glue gun, X-Acto knife, and wire cutters are needed.

Step 1: Materials

I bought most of the components from Jameco and Tayda Electronics. Tayda is a good choice when buying resistors, LEDs, chrystals, switches and other small, cheap components. I always purchase the more expensive parts from Jameco such as breadboards, integrated circuits, and power supplies. I purchased the wood needed for the base of the project and the acrylic sheet from Lowe's. Altogether, the cost of the electronic parts should be under $100. The wood and acrylic should be under $15.

1. Plenty of Resistors: Any from 100-500 Ohms should be sufficient. (I bought most of mine from Tayda)
2. Large Breadboard:

3. Small Breadboard:
4. LED's: (At least one red, one blue, and one clear.) http://www.taydaelectronics.com/leds/led-5mm-blue-water-clear-ultra-bright.html
5. Wire: (I bought wire from Jameco)
6. 7-segment LED Display: (6 are needed for this project) http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_24782_-1
7. 2.1mm Wall Adapter: DCU090050E2961: JAMECO RELIAPRO: Power Supplies & Wall Adapters
8. Breadboard Power Supply: DFR0140: DFROBOT: Education & Hobby Kits
9. 9V Battery Connector: http://www.taydaelectronics.com/9v-9-volt-battery-clip-connector.html
10. Connectors: Cable mount: 08-65-0805: MOLEX INC.: Interconnects Headers: 22-29-2021: MOLEX INC.: Interconnects Housing:  22-01-2027: MOLEX INC.: Interconnects
11. Magnet Reed Sensor: MP201701: CHERRY CORPORATION: Electromechanical
12. Switches: Mini Toggle Switch SPDT On-Off-On
13. Wood (Bottom: 1x3x8): Shop 1 x 3 x 8 Kiln-Dried Whitewood Softwood Board at Lowes.com
14. Wood (Top: 1/4x2x2): Shop 1/4 x 2 x 2 Birch Plywood at Lowes.com
15. Acrylic Sheet:  Shop OPTIX 10-in x 8-in Clear Acrylic Sheet at Lowes.com
16. Glue: Both wood glue and hot glue. 
17. Rubber Feet: BS01RCL10X20RP: JAMECO VALUEPRO: Electromechanical
18. Small Magnet: I just found one lying around but here's a link to some small rare earth magnets from Jameco: http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_2181319_-1

<p>This gave me a great start for my personal soldering/micro electronics play area. I made some modifications to suit my needs for model railroading and plastic modeling, with a bit more leaning towards soldering. My power is fed from a 12v power supply so I can get 3.3, 5, and 12 volts which is more common in my hobby. Really have no need for 9v. I also added two PC case fans to pull the solder fumes away and added additional helping hands. I added switches to toggle the different voltages with indicator lights at the connectors and a switch for the fans. I still need to add some labels at the connectors to indicate voltage. </p>
<p>hello guys n girls , i m new user of arduino. can ny1 help here??</p><p><br>i have to actuate a SHAPE MEMORY ALLOY (SMA) . it needs a voltage of 12 volt and 1 ampere of current .It cannot be supplied by usb port of laptop . so i am giving it supply through REGULATED POWER SUPPLY . ias soon as i will switch the power supply the SMA will be actuated. But i want to pass electric current in the circuit after 10 minutes i will give power supply. so i want some sort of control or triggering via aurdino. kindly help....and ny1 has any fruitful ,mail me at pushparoy7150@gmail.com. </p>
Very nice work ! I think a neat work area helps keep the magic smoke inside the electronic components where it belongs . Thumbs up ! <br>Build_it_Bob
Yeah, I can't disagree... But I still have to say... I'm sorry, but I can't figure out why did you use 6 digit displays to display always the same thing (3V 5V and 9V)... =)
= )
Hello, my compliments for the job. That sounds good. <br>I wanted to know exactly what kind of old LCD used for the LED lamp. thanks
I had one that looked kind of like that I pulled it out if an old cash register but I have seen smaller ones behind the LCD screens on coffee makers. They were separate pieces just sandwiched behind the screen. held on by plastic mounting clips.
Do you have any pictures? thanks
i'll see if i can find them in my shop i'm pretty sure i know which box they are in. It wont be till later tonight, that whole work thing gets in the way.......
I bought an lcd screen from Jameco a couple years ago and blew part of the circuit so that it wouldn't display anything. But since the back light still worked I tore it out and used that. I would suggest that you go to Tayda and order their cheapest LCD screen (about $6) and use that back light.
awesome good idea for us hackers and circuit benders.. keep it secret, keep it safe!
this is awesome im gonna build it!!! I think i might use a thicker piece of acrylic and gorilla tape it and sand blast the icons in it. sand blasted acrylic looks awesome with led backlighting <br>
Great Idea. Hand carving the shapes was almost harder then it was worth.
I am so very jealous. That would fit perfectly on the right side of my L-desk. One day.
Awesome project brother! Will surely try it when I have time.! <br>You got my vote.
Love the use of acrylic and LED back-light.... keep up the good work... <br> <br>Voted!!
Thanks, really appreciate that
That acrylic display is mind blowing! Good job overall! You got my votes! =)
Sure thing. Thanks
I like this project ... and the acrylic light makes it real special! <br> <br>Thanks for posting!
