- # Teardowns
-
- ## CyberPower 425VA
- Replacing a battery in a UPS. 2010's.
-
- ## Electronome
- A mains powered electronome from the mid 1900's. Susceptible to mains timing
- changes, and impractical. Neat mechanism inside. Vintage 1950's/60's.
-
- ## Epson Scanner Perfection V100
- Tearing down a scanner for parts. 2000's.
-
- ## Sharper Image Lantern
- LED Lanterns are a recent fad. See how a PCB is cut into four columns and
- soldered together to make the lantern light. This model failed due to the
- Potentiometer light adjustment mechanism. 2010's.
-
- ## Taylor Temperature and Humidity Sensor
- Cheapest of the cheap hygrometers. Reads up to 90% RH, then gives up, and just says
- HH. What a cop out. The board is single sided, blobbed, and consumer crap. Destined
- for a landfill, no doubt.
-
- ## Digiflam Flammable Gas Sensor
- Made in England Gas Sensor from the 1980's. Conformally coated board, and potted battery,
- make this difficult to repurpose. Simple 74 series logic construction.
- 7Seg displays for Gas Readout. Dial buttons for LEL configuration.
- Designed for portable usage.
-
- ## RKI Instruments PS2 Combustible Gas Sensor
- A simple flammable gas sensor built with a 30 foot long sensor cord to the electronics.
- This is how they manage the separation of flammable zones / divisions with this product.
- The device is not waterproof, or explosion proof. It takes 24V DC or 120V AC, and would
- be extremely light, if not for the rather large AC transformer. Heavier things are worth
- more right? No, that is a fallacy. Well built, and calibrated. Designed in such a way,
- that external sensors can most likely be plugged right into the screw terminals,
- should the original fail. Good modular design. Bigger and heavier than it should be, though.
-
- ## Dell Rack Power Distribution
- A couple of outlets, tacked onto a server rack compatible panel. Expects 240 3 phase AC.
-
- ## Eyoyo Mini VGA Screen
- Eyoyo yatto skimashita. Mini VGA computer screen. Built with connectors on board.
-
- ## WorkForce Flashlight
- An incandescent flashlight with a lead battery. From before the days of LEDs. Replacing the
- battery on this takes about 10 minutes more than it should, and is precarious due to plastic
- threaded screwholes, and awkward construction and battery access. Another product designed
- for a landfill.
