Air Flow Meters are also known as Air Mass Senors, Air Flow Sensor, Air Mass Meter, Mass Flow Meter and Mass Air Meter. Air Flow Meters (AFM) measures the air mass that flows through the air filter to the engine. This information is then sent to the control unit in order to specify the fuel injection rate.
Common symptoms for an AFM that needs replacement include:
Erratic Engine Operation
Reduced Performance
Engine Stalling or Cutout
Increased Fuel Consumption

Today I explored a side of Birmingham that I've yet to head to, Aston University and the surrounding area, and found it to be a very pleasant place to spend a sunny Saturday morning. There were few people around, students not being up at that time of day, and with this week's theme in mind I spent time hunting out that which I'd usually pass by.
I also primarily used the Sigma today; whilst the Canon pancake is rather enjoyable on account of being so compact and sharp compared to the Sigma, there's something about the 30mm focal length on a cropped sensor that just feels so... right.
i know... eewwww.
after i did a long exposure of a fountain near my house last thursday eve, i've noticed that there was these big obvious black dots on the screen. i checked the lens, blew on it and tried again, it was still there. so when i got home, i called Jon and asked on what to do. he told me about the Mirror Lock-Up and blew on it... it was still there. the saturday that i was supposed to meet up with fellow Flickrmates, we passed by Samy's Camera in Fairfax and i tried blowing it out using Jon's Rocket Blower thingy. i did a test... went fine.
so i was ok when we got to Santa Monica. then when i was looking at some of the photos that we were taking that night by the beach (long exposures), i started to notice it again, those circles everywhere, color white this time.
seriously, this is beginning to piss me off.
This is a picture of a white sheet taken with my D70. The black spots are dust. As you can see the sensor is full of it :(
Opened the failed speed sensor. Good to dry it, fill with epoxy, and see if it could be a spare.

If we learned anything at CES this past January, it’s that sensors are pervasive in every new cool tech getting to market these days. And health is definitely leading the way in this sensor proliferation. Constant tracking and monitoring through interconnected devices opens up unlimited possibilities for disease management and prevention leading up to new and remarkable business opportunities. Get the ins-and-outs of how these sensors can play to both individuals and enterprises and what companies are now doing with all of this data.

This is what the whole thing is about this week. Velidating a new hyperspectral sensor package that is deloyable on small planes. It should allow us to more rapidly characterize and assess terrestrial and optically shallow marine habitats.
Continuing to explore B&W imaging along the cote d'Azur.
Technically I've found that moving Zone 6 as Sony sensors record it and creating an input correction curve post-demosaic that lowers it to Zone 5 sets the kind of deep tones I'm looking for.
As a side note: Sony sensors are very very quiet in the shadow regions. There is so much usable information deep into the -EV range.
When "testers" and commenters across the internet make claims about dynamic range I see what they report to be 1 to 2 stops narrower dynamic range than what I see. The difference is that I rise the mid-tones in my Digital Zone System luminosity curves to match 0EV to Zone 5, which, it turns out, usefully raises the shadows down to 020202hex - where I take things to be pure black (I can't see any difference between 000000hex and 0202020hex on my displays).
My Sony A7 can record 14.5EV to 15EV of usable f-stop range. Yes. It's true. Same with an A6300 that I have. The A6000, NEX-7, NEX-5T, and A5000 all record just about 14EV dynamic range.
The A7RII I recently picked up looks like it's good for between 14EV and 14.5EV. This surprised me as I thought backside illumination might set a more solid base noise level. Perhaps it's all those pixels or the way they set the analog to digital converters?
In any event, I would really like to try a Sony A7S (original model) to see how it does. Anyone have one and have a few minutes to record some RAW data for me? Or loan me for 10 minutes so I could run my input correction curve calculations? These cameras are getting cheap enough that I might even be able to buy a used copy myself. I'll be keeping my eyes peeled for one.
Finished the temperature sensors which I now have around the house. Used a #protoshield for the #Wemos D1 mini with the #DS18B20 digital temperature sensor. Power is supplied via a #powerbank which has two 18650 Li-ion batteries recovered from an old laptop battery. With the Wemos in sleep mode most of the time and waking every 10 minutes to do the measurement and then going back to sleep, I get about 18 days battery life. I originally tried a Xiaomi powerbank, but because the current draw of the Wemos was so low when in sleep mode, the powerbank would think there was no load and turn off, therefore not allowing the Wemos to wake up! Ended up getting some battery holder/charger from eBay and they work a treat. Also needed to solder a resistor between D0 and the reset pin to enable the waking from sleep.
For the reporting/graphing, you can see the graph works for one channel, but I couldn't work out how to get multiple channels on one chart. Did some googling and came across a solution that uses HTML, JS and the Highstock charts, which after updating a couple of details to use my #thingspeak channels, it was running!
Many thanks to the following people for sharing their code to make this project possible for me.
