In this post I am going to do a deep dive into the electronics design for my simulated sunrise/sunset aquarium light project. If you have not read that post, I recommend starting with that. Disclosure: JLCPCB is sponsoring my projects, but I had already been a big fan of their …
Why? Silicone can be used to make all sorts of things, but perhaps the most popular application is sex toys. There are huge variations in personal preferences, and if you are designing your own, you can make it exactly how you like it. Have a really good toy that’s just …
TLDR: Click here. A Bit of History I remember when I first started making PCBs in ~2010, our low spec (8 mil min traces / 8 mil min spacing) 2-layer boards costed $133 for 4 copies. Special academic pricing. There were services like Sparkfun’s BatchPCB and OSH Park that were …
I am currently working on a tensile strength testing rig that will be detailed in a future post, but as part of that project, I need an Arduino shield that can drive a 12V/13A linear actuator. Electrically speaking, linear actuators are just DC motors. However, because I need to be …
I wouldn’t call myself a photographer or videographer, but I do have an action cam (Sony FDR-X3000), and often document my adventures with it. You can see some of my videos on my YouTube channel if you are so inclined (and I’d be honoured!) – it’s mostly flying, gliding, and …
