Damogran Labs is a young group of people who are into developing cool stuff. Our projects are sometimes very demanding and high tech but others may be just a reinvention of the wheel – we do it just because we can and/or want to…
We are located in Europe, Slovenia. Damogran Labs consists of an electrical and a mechanical engineer – two brothers that love either creating or destroying useful things. Sometimes a designer and other people get involved which makes us pretty much a self-sufficient team for whatever tech task we’re up to!
Investors (updated 10.3.2018)
Chaotic-Tock is not just a clock gone cuckoo. It is a clock gone cuckoo with style.
This is a designer clock made to make you rethink things we take for granted. It’s called Chaotic-Tock.
It is a completed project ready to go directly to production and it has also been featured in an Indiegogo campaign but failed due to lack of funding and marketing skills. We are willing to sell to an entrepreneur everything needed to start production, that is technical documentation, 3D models, technical drawings, electrical circuits, software, source code, manuals and other documentation. We can also provide training and support to investors.
Force sensors with unlimited possibilities.
This is a custom force sensor/load cell developed for a specific purpose with very demanding requirements:
- force sensing in both directions
- overload protection in push direction
- very compact, thin shape
- simple design and cheap production
- no creep or hysteresis
- digital communication of measurement results
Slight modifications of design allows measurements of a wide range of forces (1N to 10 kN). The measurement is not done with classical strain gauges that need to be installed manually so the production is very cheap, quick and simple.
The sensors were developed up to a point of a working prototype and were also incorporated in a working prototype of a force-based power meter. The development took around 3 years during which about 50 prototypes were made.
As with the Chaotic-Tock we can provide all the research and knowledge we acquired during development, including calculations and analysis, 3D models, drawings, electronics and source code. Unlike Chaotic-Tock, this is not a finished project – it is more of a platform to be used in design of more complex products that include force sensing. Therefore we will provide any help and support to a team that will incorporate them in their products.
Damogran Labs has developed a complete control solution for unique interactive game called Labyrinth Ljubljana in Slovenia. We created control electronic, PC software, controlled flashlights and other smart hardware (drivers, sensors, clues, …). Technical aspect of this project doesn’t need any investment. It is ready to use and be tailored to a customer ideas and games.
Check out this awesome project!
Old projects
Cycling power meter for everyone.
One of uses for Knof (force sensor) is in a cycling power meter. That is our ex project called TriPO. Its aim is to be the cheapest power meter on the market and because of its design it also has a number of other advantages over other power meters. The project was suspended on 2016 due lack of investment and team interest.
We have been doing something all the time, since childhood, and here’s something of what we’ve done so far.
It all began years ago – as soon as Lego bricks were not enough, we started to tamper with real tools from our home workshop. As kids, we tore apart every working device and reworked it to a non-working or different-working device.
However, some of those things are still in use and still work well!
Audio Compressor And Preamplifier
Guitar/bass speaker
Redesigned powerful Hi-Fi speakers into a single 250W RMS bass/guitar speaker. Really nice, clean deep tight sound.

Inside power amplifier
A bunch of new knitting techniques was invented while developing preamplifier.

Power amplifier
As custom as it can get. Line input, mic input, compressor attack and release setup, headphones output.

Compressor LED and LDR assembly
First LED and light dependent resistor assembly. LED surely is fast enough, but LDRs are slow. That's why this was just another try for the compressor.
At the end of the high school Domen earned a trip to Italy with his audio compressor and preamplifier. As with all other things, audio compressor in theory looks simple, something like voltage controlled signal divider. Well, it is far from that. We know quite a lot about compressors now, LDRs, attack and release times, … and other pure analog electronics.
Compressed Air Motor
This was Nejc‘s mechanical engineering diploma project. A compressed air motor with multi-stage expansion, each stage having variable geometry and heating before and after, it was very sound in theory, but in reality the complicated design lead to huge sealing losses. However, the theory still holds and in the future, an update will be made, switching to cylinders with somewhat more sophisticated electronic control and no sealing problems.
Instrument Condenser Microphone
Another audio project. It is quite hard to satisfy instrument audiophiles with low budget products. Its cardioid pattern sufficiently eliminated surrounding noise and its phantom powered preamplifier had features like “low cut” and “mute”. This was the first product that was actually sold online.
Software
I (Nejc) started fiddling with programming when I was 14. At the time I wanted to be as hardcore as possible so I stage-dove into vanilla C and WinAPI windows programming.
I quickly (-ish…) regained my senses and started to learn more engineering-friendly languages, Matlab, Python/numpy/scipy, C, C++/Arduino and so on. We used some in school and some for hobby.
Meanwhile, I tinkered a bit with web technologies and got a job at Blocklogic. I contributed to projects like Sellout, Timebits and PricePilot.
I don’t call myself a programmer anymore, but not many things can be made without some programming at least. When it’s that task’s turn, I rename myself to programmer, write the code, and then rename myself back to mechanical engineer.
The Not-So-Serious projects – mostly harmless… but always fun!

Camera slider
Battery powered. Adjustable speed, limit switches. Heavy duty metal chassis. Not entirely our project, but exists because of us. 🙂

Bike shifting lever
A 3D printed replacement bike shifting lever. Drawn in FreeCAD for a friend, it's been used for more than 3 years and it's still working very well!
Beer coaster
A light-up beer coaster. Only lights up when there's a glass on it and provides an insight into internals of your beer.

A gift for a friend from electronic engineer.
Polished brass and bicycle spare parts can be a great gift if prepared in correct way.

First prototype of clip-on instrument microphone
Clip-on microphone with gooseneck and shockmount, great for live performance.

Test instrument microphone
In is not the most beautiful microphone around, but it is the first one of it's kind. And the last.

Bathmobile 2
Custom truncated steering wheel was the most expensive part of this Bathmobile (besides white color).

Acoustic guitar preamplifier
Still in plan. Rack acoustic guitar preamplifier with dual channel (direct and microphone), advanced equalizer and limiter.

Bathman
This was a fun project. Build a car for competitive downhill racing. We built Bathman's Bathmobile. Bathtub is also a perfect shape in case wheels fall off. Which is exactly what happened.

Image processing
Another project involving Python, three USB cameras and transparent foil. Coming soon!
Joysticks and stepper motors
Two things were being researched here: connecting a joystick to Arduino and controlling a stepper motor. Both worked, but none was used in a particular project...
A wooden wind turbine.
A wind turbine made from spruce wood and aluminium sheets. It worked for two years, had one very thorough rebuild but was weakened by the Sun eventually. A new, plexiglass-aluminium version is on being made!

Roll bender
A DIY roll bender machine. Used for making many sheet metal parts that would otherwise be very hard to make by hand.

Creepy Clock
A creepy clock. A real-time-clock IC, an Arduino and a bunch of other components all knitted together into a very believable imitation of a brain. Programmed to flicker to simulate bad connections and power outages
PCB illuminator
We made quite a few PCBs at home at almost no cost. This was a simple \"illuminator\".
Lego car, front wheel drive.
Some build lego houses. Here is a macro shot of lego four wheel drive car made with most common LEGO bricks.
