Given the purpose these cards will likely be used for, we doubt that either of these facts matters much to the thieves. No word as to the modus operandi of the thieves, so it’s not clear if the whole truck was stolen or if the cards “fell off the back.” Either way, EVGA took pains to note that receiving stolen goods is a crime under California law, and that warranties for the stolen cards will not be honored. The truck was moving the cards from San Francisco to the company’s southern California distribution center. What happened to the good old days, when truck hijackings were for things like cigarettes and booze? Now it’s graphics cards, at least according to a forum post that announced the theft of a shipment of EVGA GeForce RTX 30-series graphics cards from a delivery truck. In true hacker fashion, it looks like the fix will be to change the software to deal with the loss of sync messages. Putting NICMOS back into the loop allowed them to test for loss of synchronization messages without risking the other active instruments. Mission controller took an interesting approach to diagnosing the problem: the dusted off the NICMOS, or Near Infrared Camera and Multi-Object Spectrometer, an instrument that hasn’t been used since 1998. The issue appears to be different from the “payload computer glitch” that was so widely reported back in the summer, but does seem to involve hardware on the SI C&DH. The problems started back on October 25, when the Scientific Instrument Command and Data Handling Unit, or SI C&DH, detect a lack of synchronization messages from the scientific instruments - basically, the cameras and spectrometers that sit at the focus of the telescope. More trouble for Hubble this week as the space observatory’s scientific instruments package entered safe mode again. Posted in Microcontrollers Tagged accelerometer, float, geolocation, LoRa, LoRaWAN, pivot, sensors, stm32, water level Whatever the situation, we do appreciate hacking sensors into other types of sensors just as much as anything else. Whether there is a design requirement to use an esoteric sensor to measure something more common, or a personal hardware limitation brought about by a shallow parts drawer, there’s often a workaround like this one that can accomplish the job. It’s also paired with a LoRa radio, allowing it to operate off-grid. As the arm pivots, the microcontroller reports its position and some software converts the change in position to a water level. This particular unit, an STM-type device with a built-in accelerometer, is attached to a rotating arm with a float at one end. needed a way to monitor the level of a remote body of water but couldn’t use a pressure or surface-level sensor, so he used a sensor typically intended for geolocation instead. But if you don’t have the exact sensor you need, it’s sometimes possible to use one sensor as a proxy for another. Moisture, pH, humidity, temperature, location, light, and essentially every other physical phenomenon are readily measured with a matching sensor. When interfacing with the real world, there are all kinds of sensors available which will readily communicate with your microcontroller of choice.
