I’ve been fooling around with ESP32s and a bunch of sensors lately, as you may have seen from my previous posts. To actually provide something worthwhile, it occurred to me to try and build a system that could monitor the canteen queue, and tell the students what the situation is …
Some of you may have followed the saga of the 8mm scanner I built, using an Arduino and a Canon IXUS95 with 3D printed parts. It worked fine, and produced results that were entirely satisfactory, to a point. I first used a 10X macro lens intended for mobile phones to …
or, bumbling your way into IoT The Internet of Things is currently on everyone’s lips. It’s the facilitator par excellence, the solver of all problems, the liquidator of all costs and the divine messenger of communications to and from devices. Or, it is an extra sinkhole of money and effort, …
I got a roll of TPU Soft filament from our very good partner, Suomen 3D-Ratkaisut Oy. Thinking of uses for it (so far we had printed an insole for a shoe for an innovation course project) it occurred to me that maybe it is soft enough to use for creating …
It’s time to wrap up this year’s busy innovation & implementation projects. As you see from previous posts, my work has been more and more moving into 3D Printing instead of just modeling, and into Arduino-based robotics in the innovation area. Only last week we held the 12th International IT …
NEWS FLASH – this project is now on Instructables.com. Please go see it there and vote for it in the First Time Author contest 🙂 As a kid, I was very interested in Morse code. There were a few reasons for this – my father was in the Signal Corps …
Ooops, it’s been a while since I was last active here, sorry about that. But to offer someting in retribution, here’s a device that can count revolutions or any other event that closes a switch, and tell you how many times that happens in a minute. I have a need …
Hi all! It’s been slow here for a little while since the start of the school year, because my first period is always chock full of first year courses. Nevertheless I have had the coffee breaks and sundry moments to finally bring the 8mm scanner to a version I will …
As most of you know, I am not an engineer, despite my lofty ambitions of tinkering with all sorts of things. So, the other day Jouko Lehtomäki from Suomen 3D-ratkaisut, the partner company of my university Haaga-Helia, brought us a brand new CoLiDo DIY printer in a crate. He said it’d be …
I recently had the pleasure of visiting Thrinno, a Belgian company based in Ghent. Thrinno is working on a cloud-based system that enables companies with 3D metal printing needs to assess the print process virtually, find the best orientation for printing, and most importantly, get a quote on the price …
