Ok, so now I know that I need a bridge rectifier, but what is it exactly? Just remember that it's part of the AC wiring. I won't talk about it either in the following steps. If you dig a bit deeper, you can find a micro switch that cuts power to the unit if the bin is removed. Note : the actual voltage from the outlets in your home may vary. We now also know that we need a way to convert 120V AC to 120V DC.Įnter the magical world of rectifier bridges! The fact that this is a 120V motor can be considered a good thing, since no transformer will be needed in the new circuit. The other two are blue, and from what I can tell, they are probably from a sensor of sorts, since there was an overload LED on the cover. In this case it's a 120V DC motor. Note that there are 4 wires coming out of the motor,and two of those are obviously the DC power wires since they are black and red.
When taking out the motor, check for a sticker with the specs. correct me if I'm wrong, but nonetheless.
I have my doubts about reversible AC motors. I of course kept the board for any salvageable components in a future project.Īpparently, this shredder came in a version with an AC motor, and a version with a DC motor. In my case, I had no clue as to what was broken, so I just removed the circuit board and cut the wires as close to the board as possible, in order to give me some room to move later on. Soldering iron and solder - recommended, but it's possible to do without.ĭremel - again, recommended, but it's possible to use other cutting tools Insulator for some connections - heat shrink, electrical tape, marettes.Ĭrazy long philips screwdriver - I used an 8 inch #2, but it was tight, so maybe a #1 would work better On-off switch - optional if your DPDT switch has an off position let's say that I hadn't quite grasped the mindset of photographing for instructables yet. The downside is that this project was done way back in February 2010, and the first steps were not documented with photos. This is my first published instructable, yay! The simple fix is to make a basic circuit that will run the motor forwards and backwards. I always wanted to get a shredder to dispose of sensitive documents, so when I stumbled on an ad for a broken shredder to give away, I jumped on the occasion!īasically, the electronics inside were shot, but the motor was in perfect working order. Fabricated with durable materials, it makes a tasteful, long-lasting addition to any business setting.Here is one way to inexpensively bring a shredder into your home office! Measuring 12 by 12.7 by 10.3 (LxWxD), the Staples Mailmate M7 Shredder is impressively compact and runs at a low 65 decibels. A handy 1.62-gallon bin keeps shreds tidy and pulls out, allowing you to quickly and cleanly dispose of material in one step.
The Staples Mailmate Shredder features an auto-reverse jam-protection function, automatically reversing jams to keep operation running smoothly, while built-in thermal overload protection adds safety. Additionally, the shredder's advanced V-Track blades are powerful enough to take on heavy-duty items like staples, credit cards, and CDs/DVDs, so you can securely dispose of several formats of sensitive information with one unit.Īuto-Reverse Jam Protection for Smooth Performance Featuring Cross-Cut Technology, this efficient shredder can shred up to 12 sheets of paper per pass, amounting to 380 sheets during its five-minute continuous runtime. The Staples Mailmate M7 Shredder is ideal for anyone looking for a streamlined shredder that takes up minimal space, but gets the job done.
