# JérΩ > Half robot, half g33k. ## Posts - [Why Add a Polarizing Lens to a Microscope](https://grey-capybara-178405.hostingersite.com/2025/09/why-add-a-polarizing-lens-to-a-microscope/): When I first started designing and assembling my own PCBs with SMD components, I invested in an optical microscope. It wasn’t cheap ~$700 but it was worth every penny. (There’s one detail I wish I had known before buying it, but that’s a story for another day.) I’ve used this scope for years, but recently I came across a video from Engineer Bo that showed how adding a simple polarizing lens can eliminate the harsh reflections from shiny components. That instantly caught my attention. I managed to grab a 52 mm circular polarizer for just $8 off Facebook Marketplace Building […] - [X-Wing Airhogs from Spin Master](https://grey-capybara-178405.hostingersite.com/2025/09/x-wing-airhogs-from-spin-master/): Before we start, check out the 21-second homemade commercial I created to showcase a toy concept I designed. I’m really proud of this one, we got green screen, real flight and 3D animation (done in Solidworks). It took a lot of planning and effort, but it was worth it. https://www.youtube.com/watch?v=e52JjScBScQ How It All Started This story begins during my time at Solarbotics, where I did two internships. Dave, the owner, had connections with some Canadians working at a toy company in Hong Kong called Spin Master. Thanks to that connection, I ended up landing an internship with Spin Master in […] - [Learning in 2025 - NotebookLM](https://grey-capybara-178405.hostingersite.com/2025/08/learning-in-2025-notebooklm/): My wife and I made a pretty drastic move, we packed up the whole family and left Canada for Silicon Valley. Why? I landed a job in what many consider the mecca of engineering. I work in aviation, designing, building, and debugging manufacturing machines that test equipment before it goes on an airplane. It’s a blast. Every project is different, with different technology inside. It pushes me out of my comfort zone almost daily, and sometimes I find myself solving problems with tech I’ve never touched before. Recently, I’ve been working with pneumatics. I thought I had a decent grasp […] - [SolidWorks to Bambu Studio in One Click: Create a Time-Saving Macro](https://grey-capybara-178405.hostingersite.com/2025/08/solidworks-to-bambu-studio-in-one-click-create-a-time-saving-macro/): If you use SolidWorks and 3D print with Bambu Studio or PrusaSlicer, this tip will save you a ton of time! This guide will walk you through creating a macro that exports your active SolidWorks part as a STEP file and automatically opens it in Bambu Studio with one click. I’ll also share another macro that generates both STEP and STL files at the push of a button! Here are the steps to create new macro. Here is the code below: – change line 14 with your path– line 38/39 is if you want STEP or STL– line 48 is […] - [Outdoor repair](https://grey-capybara-178405.hostingersite.com/2025/07/outdoor-repair/): This weekend at the park I notice the table wasn’t straight. It was simply a screw that came loose. I didn’t have the correct screwdriver bit on my knife but turns out the other side which is 1/4” hex bits was the correct size! I can now eat my sandwich in peace. - [Wordpress image link to file by default](https://grey-capybara-178405.hostingersite.com/2025/07/wordpress-image-link-to-file-by-default/): As I setup my wordpress blog, I start to find problem that are like déjà vu. Everytime you add an image in a blog post, by default its not clickable. You can not click it to see it bigger. I have to manually do it for every picture. This is how you have to do it I always forget to link all my images. It’s after I post the article that I notice. I knew there was this settings and after few minutes on google, I found it. Here is the 14y old answer after you save, create new post […] - [USB C Repair](https://grey-capybara-178405.hostingersite.com/2025/07/usb-c-repair/): My daughter ask for help when her nail polish machine stop working. The UV curing led was turning off really fast. I thought it was my USB powerbank turning off until I turn it over and notice the USB cable was plug but wobbling in place. I unplug the USB and lost the USB inside the device. Took it apart and it was very obvious! It turn out it’s not just the usb connector that got rip off but 2 traces. Since the PCB is single layer and very pale took me a second to figure it out. Thanks to […] - [New Beginning](https://grey-capybara-178405.hostingersite.com/2025/06/new-beginning/): Welcome to the Jerome Demers.com! After losing my old website (long story for another day), I decided to start fresh — cleaner, simpler, and more focused. This space will grow as I share my projects, experiments, and thoughts along the way. It feels good to build from scratch again. Sometimes losing something is the best excuse to make it better. Stay tuned. ## Pages - [Portfolio](https://grey-capybara-178405.hostingersite.com/portfolio/) - [About](https://grey-capybara-178405.hostingersite.com/about/): Hi, I’m Jérôme Demers, an engineer, builder, and problem-solver.
