  • News - Fluke Responds to Tradema… | last month

    Excellent handling by Fluke. Very rare for a company to take that sort of action when all that happened was they were protected by the rights previously granted to them. Also, excellent handling by Sparkfun in donating the units rather than selling them. Good will spawns good will. Can’t get much better than that!

    As for Fluke’s products….. When I need to care about the results I get from a meter, I only use Fluke. Period.

    “Black Shoelace” (may not make any sense, but hey, the arrow is pointing to it, so it must be the correct answer…..)

    I got as far as this one and decided not to enter. This is a shoe-in! +∞

    The office ergonomics initiative took an odd turn when they hired the new guy unfortunately named “Ergo”.

    This picture would make a lot more sense you could see the unicycle he is sitting on……

    Nice write-up and thanks for sharing your experience. At work, we manufactured a product for a customer that had the SHT11 and the customer was unaware of the rehydration notes. I actually discovered it while reviewing the datasheet for other reasons. Keep in mind though that Sensirion does not declare it as a requirement and the risk of offset readings can be minimal in some cases. Per the additional comments in the datasheet and from my experience, finished goods that were stored in a typical warehouse in normal packaging for several weeks, would not show any signs of offset readings. The polymer rehydrated from the natural environment which had a typical humidity of 35-45%. Even though the customer did not follow the procedure for close to a year, they never had any issues with the ~3,000 units that were manufactured. (every single unit was validated for accuracy during deployment of the product at an install site)

    The implementation was driven by the company’s field tech(s), but a lot of leg work was done by our internal staff as well. The system runs on a foundation of Cogiscan’s hardware/software…(cogiscan.com). As for MRP, we are using Infor LN (http://www.infor.com/product_summary/erp/ln/) and with the right set of skilled people, it works well. It is really not designed for a CM like us, but should be much better for a small OEM like Sparkfun. Much cheaper than SAP (which I loved at my last employer, Jabil). I don’t recall the system we had at HP when I was there in the early 90s.

    I am glad that I never worked at a company small enough to not have a cycle count team as part of the inventory control group. Been through several MRP systems that manage inventory in multiple ways that make basic parts management a walk in the park. At my current employer, we recently implemented a module that tracks our SMT parts down to the feeder, reel, and location on the machines. The machines communicate in real time as they are consuming parts and update the inventory. Each feeder has an RFID tag so when a reel is associated by barcode to the feeder, we know where that part is when it is on any machine.

    Actually, the UART version uses all 6 pins. The pinout chart for the UART version is inadvertently split across the two columns of the data sheet due to poor document formatting.

    I’d like to know the current draw for the backup power that maintains fix data for quicker startup.

No public wish lists :(
