Mobile electronic workbench
Some news about one of my last projects.
It all started when i read an article on the blog “Rhaaa” . We happen to share the same difficulties when it comes to make my wife accepting the invasion of the kitchen table with all my electronics stuffs.
Typically, when I start working on a project, I need the soldering iron, a power supply, a mountain of little boxes with diverse components, wire spindles, various tools, etc … It takes a lots of place, is quite long time to install, and even longer to store when finished. The ideal would be to have a way to “roll out” all the stuff on the current project, and be able to pick it up quickly before going to bed.
Organization of the component stock
For storage and transportation of components, I’ve made a “portable closet” by assembling together two component storage cabinent of 48 drawers.
Each lockers cost me less than 20 euros at Brico Depot . The pair of handles and piano hinge only cost a few euros. For the lock, I used a security door lock for baby. The storage place available in this cabinet is plenty enough to store all my stock of electronic parts. When closed, the racks are snugly facing each other and there is no risk of the whole mix.
My main regret is that these lockers are not provided with small wall needed to divide the drawers into 2 or 3 sections. I am using cardboard in place, but it is not really rigid enough and components slip below … if anyone with a good idea, let me know!
The purpose of this arrangement was to bring together in one box all I need to work on an electronic project: 12V and 5V, soldering iron, …
I scavenged a PC power supply to provide 12V, and 5V. The assembly has already been described many times. Here , for example. The tension outputs both on banana plug and speaker connectors .The latter can not pass high current, but they have the advantage of allowing quick plug on wires. On the 5V line, I also installed a USB connector as a bonus. Practical to supply an arduino. The transformer of the soldering iron is also inside the box. The iron can be plugged in the jack plug. Finally I also added a small 12V buzer that I use as a continuity tester to control circuits (white plug right). 230V outputs are also present. To avoid accidentally connecting a low voltage banana plug into the 230V circuit in, I placed a mobile plexiglass panel in front of these jacks.
On the front shelf, 4 breadboard, and the little drawer underneath the basket allows me to store all the small items. And for lighting the workplace, I use this snake led light plugged on the front USB plug.
