Hardware and Firmware Engineer
For a while now I have been using my custom ambient sensor board as well as my custom LED controller in combination with HomeAssistant (and ESPHome).
They are now available separately as OpenSENSE and OpenLED projects and are also available on the WebShop.
Leave a CommentCamera slider is a great tool that in the hands of a great video maker allows them to create amazing time-lapse videos, move the camera to follow the subject or move the camera around to highlight a fixed subject. Unfortunately, I am not a great video maker. However I am a maker and making my own camera slider sounds like a ton of fun! That is why I decided to make my own WiFi enabled camera slider. Using the 2020 Aluminium extrusion and few off-the-shelf components allows the camera slider to be as long or as short as we need it, while being very sturdy and also lightweight for carrying around or mounting on a tripod. We can then use built in WiFi connectivity to control and program the camera slider to have a very precise and repeatable camera movements.
80 CommentsIn the past, I’ve used several filament dry boxes, but none of them had all the features that I wanted or even what I thought every filament dry box should have by default. So I decided to make my own. As always all the source files are available in case you decide to build one for yourself. But either way, you can watch the video and maybe pickup few ideas and improve on them. So, let’s make an awesome controller for 3D printing filament dry box!

In the video above, you can see first a power up sequence where all four dials go from zero to 100% and back to zero after which they start showing real time CPU, Memory, Network and GPU usage. After that we run a internet speed test to show how the real-time information is displayed on the dials.
I am very pleased to announce that this project has turned into a product!
Thanks to collaboration with Streacom, you can now purchase VU Dials.
This one is a very simple but cool project, something that I would recommend to anyone who is interested into DIY electronics, gadgets and learning new stuff in general. It is definitely one of those projects that don’t require too much time but you can learn a lot by making it and also earn a lot of credit by sharing it with your friends and family.
Below you can see a final product. It’s a heart shaped, touch sensitive, keychain for your loved ones. On the front side there is a smiley face drawing that has eyes and mouth. Eyes have two red LEDs that will start to pulse once you touch the keychain or place you finger on the smiley face (see it in action below)
9 CommentsAnother weekend project that I’ve been working on is Wake-up light. Lately I’ve been doing more research on sleep phases and how to “hack” your brain to wake-up more refreshed and adjust your sleep cycle. There are many studies out there explaining this and providing scientific evidence, so if this is something you are interested in, I encourage you to go and get more detailed information on this subject. However I won’t go into too much detail, I’ll just try to give very simple explanation: When you sleep, you are either in REM or deep sleep (NREM) phase. When you wake up in REM phase you feel fresh, relaxed and full of energy. When you are woken up during the deep sleep phase, you feel like you’ve just been hit by a bus, and you take long time to actually wake up.

I’m working on a new weekend project that will be released as soon as I finish the Windows application and it will be released as open-source open-hardware project. The uber-cryptic title stands for “Power-supply Active Load tester”.
Recently I was in need for a simple device that will draw reasonably precise amount of current from my power supply unit under test and read the voltage and current draw. There are a lot of schematics and products that do just that, or you can do this just with two digital multimeters, op-amp, mosfet and potentiometer and that will probably work just fine, but I wanted to create my own version and try to improve it. 🙂
The idea behind PlusPon project is that you don’t have to visit hundreds of daily deal sites just to find what you are looking for, instead you can visit PlusPon.com that lets you search thousands of daily deal sites at once and lets you filter offers by region, category, price or any other way you want. All deals are displayed…
