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.
Recently I have been in need for a proper power supply as I have been tired of using the LM317 power supply that I first made. After a lot of research and searching I have finally made the decision to buy a cheap power supply just for the moment, while I am still trying out very simple circuits which do not require a specialised power supply for them. My choice of power supply finished at the Atten 3003S. Since I already have another Atten product – The 858D+ hot air rework station (as seen in the background of the image below) and I because I was very pleased with the construction and the quality I decided to go along and order the power supply. The price for the 3003S is just under $100 which is a perfect price for an electronics hobbyist. The power supply took about 3 days to order since it was coming from an Australian seller (eBay seller “carmates”) and not from overseas. Upon receiving the product I was very surprised that they shipped it in the original box instead of putting in into another box for protection. Luckily the power supply survived the journey and was received in excellent condition.
