In my previous blog ESP HomeKit SDK – Flash I showed you How to Use a ESP as a HomeKit device. Now there is a new version on the market. About In 2015 the ESP8266 took the embedded IoT world by storm. For less than a few bucks, you could …
When you are starting with KiCad you will soon be searching if there is a option to add custom parts. KiCad has all common parts in it’s standard libraries, but it can’t hold all parts that are on the market. SnapEDA solved the KiCad libraries “problem”, SnapEDA is a free …
In the past I wrote about HomeBridge and Homekit2MQTT. In the past wrote several blogs about sensors, lamps, etc. for both home-bridges. The bridges where installed on a Raspberry Pi®. I made a little summary for those that are new to my site. HomeBridge HomeBridge – Relays & Lights HomeBridge …
Remember the movie “Edge of Tomorrow“? (also known by its marketing tagline Live. Die. Repeat.) Cage is killed in combat, he finds himself in a time loop that sends him back to the day preceding the battle every time he dies. Kinda like the ESP8266 when it repeatedly resetting… Nothing …
Hand soldering Surface Mount Devices (SMD) scares a lot of Makers, but it is easier than what it looks like. Even sometimes, it’s easier than soldering Through Hole Components. Really! The Components are naturally held in place by their legs, while SMD are just sitting flat on the PCB, only …
In my previous blog I covered the hardware and software and part II here for my Raspberry Pi® – Powerunit® project. Now its time for the PCB Design. KiCad Although KiCad (pronounced ‘Kai-Cad’, not ‘Key-Cad’ like the thing that goes in a lock) is the new hotness when it comes to …
In my previous blog here, I have figured out the basic hardware & software setup for my Powerunit® project. Now Its time to fine tune the Software for my Powerunit® . Powerunit® Project – Software phase Now that the everything is working I want to fine tune the software a …
How to program a ATTiny I discussed in my previous blog here. But I want to go even smaller! In stead of using the “big” DIP IC housing I wan to use the smaller SOP IC housing. But then I realized how to program these tiny things, they don’t fit …
One thing that was still missing for me on the Raspberry Pi®, was the inclusion of some kind of power switch. Considering how many common Raspberry Pi® projects could make use of this functionality. Still, we’ve lived with this problem with the old version for a long time, and there …
For an upcoming project I need to improve the electrical characteristics of the PCB by increasing the width of the Ground and Vcc tracks. Let’s start with the track width. You can control the width of each track manually. The method involves creating custom track’s widths and then applying one …
