This question is important, because due to the age of the device, it may be impossible to open it without incurring some small damage to parts (most notably the bottom foot and internal fan). Having said that, it's also completely possible to perform the repair without causing any permanent...
Stethoscopes are simple, low-tech devices that still offer healthcare professionals a wealth of information. Creatas/Thinkstock Sound has been used as a diagnostic tool for millennia [source: NPR]. You can learn a lot with an ear — or the bell of a stethoscope — to a person's ches...
as well as on the vinyl door gaskets. the solution to this problem is to insert tiny heating elements in the front of the refrigerator, just large enough to slightly warm those front surfaces to the point that condensation no longer forms. while the heaters don't draw a large amount of ...
Back home, I did some troubleshooting and hooked up a straight key to the QMX and it worked: I was able to finish a few CW QSOS without a problem, so the finals were definitely OK. I then set up the system again for FT8, and sure enough, I was able to make a contact. Because...
Often, you will see a large number of capacitors on an ESC board. These are for noise filtering generated by the motors and FETs. However, regardless of the amount of filtration available on the ESC, you should always solder an additional capacitor to the power pads of your ESC. This will...
The plastic nature of the SD card and its tiny parts make it easy to break. On the side of most SD cards, you can see a ‘Read-Only’ lock that is used to protect the drive from reading and writing data. This switch is the most implicated when it comes to physical SD card damages...
Motor manufacturers are constantly experimenting with different designs and levels of hardware integration, which has led to advances in cooling and even integrating ESC inside the motor. Personally I think solder tabs on the motor can come in handy, it allows you to use a lighter gauge wire to...
Hook up the S-350-27 unit in series and then tune it down as low as it will go which should render the assembly down to about 63V; it is a tiny bit high for 15S LiPo but good enough for use with a BMS. Shopping thoughts: Though the -48 units are easy to find, the -27 ...
Tiny ampoules already had been used as objects in some kaleidoscopes. Bush's patent specified ampules with "two or more liquids of different densities or character, or a liquid with a solid or solids." Bush wrote that the liquids within the ampoules should be unable to mix and each would...
