Welcome to a new InTheMail, the series that will touch both your passion for electronics and your bank account at the same time. We’re gonna start with this kit of silicone hook-up wire, I was running out of thin silicone wire so I thought it would be a good idea to try one of these kits. The one I got is 26AWG, 6 different colors, each about 9m in length.

Voltlog #230 – Guidelines For Board Level Temperature Sensor Layout & Placement
Welcome to a new Voltlog, today I’m gonna show you some techniques that you can use when doing temperature measurements. Typically you will want to measure either the ambient temperature or the system or component temperature. Depending on one of these goals you are going to follow different design rules to achieve that. And to better illustrate the problems, I have these 3 pcbs which have exactly the same electrical circuit but with different layouts on the pcb.
The boards consist of an esp8266 and a digital temperature sensor and you might expect that since all 3 boards are placed so close together, they should all indicate the same temperature but that is not the case as we can see on this graph we are getting 3 different temperatures and only one of them is close to the actual ambient temperature measured with another thermometer, so why is that happening? Well the answer lies in the layout of the PCB and that includes component placement, copper planes and various other elements on the PCB.
Voltlog #219 – InTheMail
Welcome to a new InTheMail, the series that will touch both your passion for electronics and your bank account at the same time. We’re gonna start with a set of 3 prying tools from Best which is kinda of known in the mobile phone repair business, it’s a Chinese brand that sells this kind of tools. I like these because they have a nice rubber handle which provides a good grip for when you’re trying to pry open an enclosure.
