What a peaceful Chinese New Year! I flew back home two weeks before and had a valuable break – have dinner with my family, hang out with my best friends, and play Total War: Three Kingdoms. Now I’m ready to fly to Suzhou and be your eyes and ears again! I finally got a real camera (Lumix G95), which will undoubtedly lift the quality of pictures and videos I take in the future!
While the firmware team is hard at work to unlock more of Spectrum’s features, the hardware hasn’t been sitting around idle. Our development samples have been thoroughly tested as planned to ensure everything is reliable – not just when it comes out of the box but for years to come.
|Electrostatic discharge immunity||Passed||Electrostatic discharge is applied to multiple parts of the housing and each port when Spectrum is operating, stand by, and off.|
|Package vibration test||Passed||Spectrum is tested on a vibration table by fixture, where it’s packed in the box and loaded onto a carton; the box is wrapped by a PE bag and sealed by tapes the same as how it will be shipped in a container.|
|Package drop test||Passed||A machine drops Spectrum with the box from different angles at a maximum height of 1.8m.|
|Wall mount strength test||Passed||Spectrum is fixed with items two times its own weight, and the whole is mounted to a wall via the VESA interface and sustain 24 hours.|
|LCD monitor stability test||Passed||Part 1: An operator tilts Spectrum (on the stand) to +5º and release; it should not tip over. Part 2: Spectrum (on the stand) is placed on a 10º slope; it should not move.|
|Kensington test||Passed||The Kensington lock is activated, and 20kg force is applied in various directions of the key; the lock should not come off.|
|Rubber foot test||Passed||Slide Spectrum (on the stand) on a wooden table for 30cm; the rubber foot should neither detach nor leave colored marks on the table.|
|Stand base support strength||Passed||Push 3kg force from the front of Spectrum (on the stand) for 3 seconds; Spectrum should not tip over.|
|Hinge test||Passed||Spectrum (on the stand) is height-adjusted 3000 times.|
|All ports and stand detach test||Failed||All USB ports are plugged and re-plugged 5000 times; all non-USB ports get the same treatment 500 times. Color deformation on the USB ports is observed during testing, which will be improved in future development samples.|
|Power button||Passed||The power button is pressed 5000 times; it should look and feel the same after and before the test.|
|Joystick||Passed||The joystick is clicked 5000 times in each direction (left, right, up, down, enter); it should look and feel the same after and before the test.|
|All inner conjunction cable detach||Passed||Spectrum’s internal cables and connectors are plugged and un-plugged five times; they should still connect as usual.|
So far, Spectrum has passed about half of the planned reliability and endurance tests, but testing is still ongoing, and we will, of course, keep you in the loop.
Fun fact: All of the “5000”, “3000”, and “500” times of operation are conducted manually.
Introducing Spectrum’s Cashew paint, the “boilable” paint from Japan.
In Suzhou, a co-working engineer, his voice filled with awe, told us that this paint can be “boiled” for 4000 hours and still feels exactly the same as before. When we look deeper, according to Cashew, it can sustain an 85℃ environment with 95% relative humidity for 4000 hours with no touch-feeling change. This property of the paint can help Spectrum maintain its look and feel even in hot and humid climates.
We have been comparing it side-by-side with another paint suggested by our suppliers and found out that the slight glossiness in this paint helps bring out the correct amount of details and makes Spectrum’s housing more resilient to fingerprints. Additionally, testing shows that the paint has rubber elasticity, high tensile strength, as well as nail scratch, oil, and chemical resistance. All of these help Spectrum’s housing stay in shape and reduce maintenance in the long run.
We have been working on the OSD multi-language table during the past week. With the help of our customers and @senior_creators, we will soon complete Spectrum localizations in Chinese, French, German, Japanese, and Spanish.
Our firmware team has switched to merging new HDMI 2.1 code into Spectrum’s firmware that we just received from scalar supplier Mediatek. Recently, they have completed half the requirements for user-upgradable firmware, as one of the two chips involved can now be upgraded through USB. They will continue this task once HDMI 2.1 implementation is completed. As always, you’ll be the first to hear the news!
