Remember that $4 multimeter that I took apart? Well, I still have it. And its not very reliable nor useful. So, I have decided to make it useful! How you may ask? Well, I am going to make it display temperature so I can estimate the temperatures of different components and heatsinks. This is based on a tutorial by Embedded Lab, so I take no credit for the idea of this build. Here is the link to the project: http://embedded-lab.com/blog/?p=4951. I was thinking about doing a tutorial, but it’s already on Embedded Lab and I don’t want to plagiarise so I am just going to go through how I built this and a few modifications that I have made to the original circuit.
You know those really cheap $4 multimeters that you see on eBay and Amazon all the time?
Being myself, I couldn’t resist and I had to buy one! So just a few days ago it came in from the post and I gotta admit that it took it an awful long amount of time to get here, almost 3 weeks! Besides that the thing came in a padded envelope and even with that the box was still a bit crunched up, but the multimeter was safe!
My impressions will this whole thing was a big roller coaster, but lets start from the beginning. First impressions, the packaging was fairly cheap and the box looked like it had been through a big journey. The instruction manual was surprisingly well written for such a cheap multimeter and the multimeter and probes felt very solid and quality.
