This is going to be the last part of DIY USB-C adapter and micro amplifier post series. Today, I will show, how the amplifier was fully assembled to a fully finished device. Table of contents Previous parts for this topic Device’s construction The ALC4042 USB-C DAC The INA1620 amplifier board Whole assembly and final thoughts … Read more
Yet another step towards DIY signal generator’s design finish line. This time it is a battery charging circuit based on a Texas Instruments BQ24295 chip. In previous parts I have mentioned that the generator needs to be powered from a battery. So, this circuit is going to be the one responsible for making it possible. … Read more
Today I am going to continue with the DIY signal generator based on the AD9833 IC where I have left in the second part. Earlier, I have talked about how I had built second analog signal generator’s stage – offset adding circuit. Because the generator is going to be digital, potentiometers should be replaced by … Read more
In this post I am going to continue with the DIY signal generator based on the AD9833 IC where I have left in the previous part. Earlier, I have talked how I had built my first analog signal generator’s stage – variable gain amplification circuit. Usually, a generator needs to have an ability to change … Read more
As the name suggests, I am going to write about a self-made signal generator based on an AD9833 IC. Also, this is going to be a multi part post, as it is impossible to design and make a fully functional device within a short period of time and even write a single huge blog post. … Read more
A regular camera stand is always handy when you need to shoot still photos. But three-legged stand is not very convenient if you want to make some top-view photos of an object placed on a table. For this reason, I have 3D printed a desk stand. Part List 25mm (~1 inch) outer diameter stainless steel … Read more
