If you have ever designed your own PCB with ESP12 module on it, probably you have left some kind of a connector to program the module. But what if you don’t want to have an extra connector or you don’t have enough space on a PCB? Then you could use an pogo addon for ESP-12 … Read more

Handful of older generation AVR MCUs needs ISP (In System Programming) connector to flash your own firmware. Usually if you design your own PCB, you will place somewhere 6 pin header (2×3 pins) as ISP connection. Most of the time it makes sense, unless PCB needs to be small especially in its height. In these … Read more

This tutorial is about an UV exposure method for making you own PCBs in home environment. This method allows you to etch boards suitable even for tiny SMD components (except maybe for BGA parts). Although it takes some effort, making PCBs at home allows you to design, make, solder and test prototypes faster than ordering … Read more

So, I have received the PCBs which were designed for the DIY portable signal generator. This post will be more about the PCBs and its manufacturing tutorial than a regular update on the project. So, it might be useful for those who wants to get their own PCBs manufactured, but don’t know how to do … Read more

This post is going to be about a graphical user interface for DIY generator’s display I have talked about earlier. Also, this post will be a short one.
