  • [Firecracker Analyzer] Testing the Texas Instruments BQ25504 - Success?

    My Question to TI

    Does the VSTOR Pin provide output voltage in the absence of the VIN BUT in the presence of a Storage element.? NOT!



    I finally got around to testing the BQ25504 and it was not what I expected but I am stupid so its all good…

  • [Firecracker Analyzer] Successful QFN Assembly

    Not a very complicated post just a few pics of the assembly.


    I use some flux and copper wire strands and used it to sweep the extra solder out... The above is the result and I check with the DMM to see if any pins were bridged. They weren't  .


    I then…

  • [Firecracker Analyzer]Brief update

    Its been a hectic couple of weeks and progress has been slow. I will be posting a series of smaller posts to cover work done and my "evil plans". One of the factors that contributed to my slow progress was sensor selection and I am still a bit stuck on…

  • [Firecracker Analyzer] [week 1] System Design and ReDesign

    I had already proposed a design but it was a bit rough and after talking to some sensor vendors, I found that not only are gas sensors expensive but most of them might not be suitable for outdoor use at all. Hence I have cut down on the sensors and added…

  • [Firecracker Analyser] [week 0] Sensor Research


    In order to make the system work, the first thing we need are sensor. I did some search and this is what I came up with. I need to fit sensors, parts and possibly some smd equipment into budget and that has made me fiddle with the design a…

  • Sensor procurement

    Hi everyone,

    This challenge involves the air to be sampled and sensed. I was wondering if anyone would like to share sensor information and their vendor info because the element14 catalog falls a tad bit short on that side. Ravi has pointed out some vendors…
