past projects

For 8 years I have worked in Skriware as a Head of engineering, I have designed, prototyped and then manufactured 2 models of 3D printers. My duties covered mechanical design, some electronics design, procurment for off-the-shelf parts as well as procurement of custom parts from manufacturing subcontractors - sheet metal bending, thermoforming, metal cnc milling and PCB/PCBA. I applied and received R&D grant from NCBiR - Fast track. Grant was used for further development of 3D Printers as well as software and electronics for Skribot robotic platform. 

Skribot system was designed by me and my team at Skriware. I designed and verified manufacturability of parts both with 3D printers and injection molding. I also designed first few interations of control electronics and other PCBs used in the robot. Later in the process I managed a team that developed electronics and software to expand that system under R&D grant - Fast track. I am listed as an author of the issued patent for fastening system used in Skribot.

For the company Edustick I have developed a 3D pen - overall shape, mechanical design, injection mold manufacturability as well as electronics - PCB design. The task was to create a pen that can be manufactured without violating previous patents. I succeeded, I am listed as an author of the issued patent for this type of 3D pen. 

This is from my venture into industrial automation - I have designed and built a 3 phase control cabinet for a cable and cable harness spool winder. It controlled dual spool lift motors, variable speed spool spin motor and a spin motor disconnector system. Everything was controlled either by a remote or buttons on the device. Everything was managed by Siemens PLC. Whole device handled spools up to 2,5m in diameter and up to 2000 kg. 

I have designed and built a EV charger stand to be manufactured and used in Indonesia. It consisted of sheet metal frame, acrylic inserts and custom electronics. Whole device contained some animated LEDs that reacted to the charging process and was able to be controlled remotely via LTE connection. Later revisions reduced complexity and "flair" in favor of manufacturing cost reduction. 

One of my gearbox experiments, works like strain wave gearbox but there is no strain - just wave. Probably useless but looks cool. Photo is also a link to the video of it working.
