Voltlog #224 – InTheMail

Welcome to a new InTheMail, the series that will touch both your passion for electronics and your bank account at the same time. We’re gonna start with this small and modern looking remote control. I actually like how this feels, even though the cost was just $3 shipped it just feels well built, the quality of the plastic is nice, the buttons have a nice click and it comes pre-loaded with batteries.

You can then use this remote control to open the garage door or whatever you like to control. But do note that this will not work with all 433MHz remotes, because some remote controls employ some form of coding, to protect the signal from being easily cloned. Take for example the automotive key fobs, some of those work on 433MHz but you won’t be able to clone them with this remote. Nonetheless, useful for creating a copy of your garage door remote control or even better, you could hack this remove and integrate it into your car dash console on some of those unused button slots. That would be a cool project.

Welcome to a new voltlog, the series that will touch both your passion for electronics and your bank account at the same time. We’re gonna start the video with a battery charger from Liitokala, model number is Engineer Lii-500. It works with an external 12V power supply which I opted not to get because we all have a bunch of 12V adapter from old equipment.

Hello everyone and welcome to a new InTheMail the series that will touch both your passion for electronics and your bank account at the same time.

We’re gonna start with this interesting looking controller type module. So we got what looks like a big switching device here that probably needs a heatsink. Well this is a beefy triac, it can do 100A and can also withstand 1000A non repetitive peaks. We’ve kinda started from the wrong side, from the output but that’s what stands out from this module. We have an opto-isolator which has a triac output driver, separating the two sides of the board. Let’s check the clearance on the back, they have something like 3mm clearance in this area. If I were to design this, I would have done it with at least 5mm, I don’t see the point of extending this ground poor so close to this track which is on the hot side.

Links for all of the items can be found in the video description on the youtube page.
