So recently I’ve been playing with LTSpice (sparingly of course since I have standardized tests coming up) and this is actually my first time doing any circuit simulation with a SPICE program. The circuit you see above is a buck-boost regulator using the LTC3114-1 from Linear Technology, honestly though their chips are really expensive… Read More
Here we now begin with a new project: The lightsaber
Of course it won’t be a real one, otherwise I would be winning a Nobel Prize right now. It’ll be one that uses those Polycarbonate Pipes and probably a aluminium or steel hilt. It will contain custom electronics brewed up by me also! Anyways here is some concept art on the design.
Well all of you know that the Divergence Meter runs on Magic Smoke right? Well somehow today for some reason it has let it out…. After running for 3 months or so continuously on a plug-in Power Supply, I wanted to change the batteries and bring it outside for someone to see. And so I did. After leaving from a show and tell session in which it ran somewhat perfectly, the voltage regulator namely the TPS62160 5V DC-DC converter IC turned red hot and poof…..*insert poker face* well I don’t know the cause but all I know is that it broke and I have to fix it….or remake the main circuit board altogether. Thank god I designed it with a somewhat modular design or else I would have to replace the whole freaking thing =___=
On the bright side, I have a chance to video record the assembly of the the new board if I choose to remake it. But still *poker face x1000* -______________-
Well if you look closely you can see the molten blob of metal where it burned red hot 🙈 and wow I really didn’t notice the amount of flux still on the board :/ I’m pretty sure I washed it all off with alcohol and water after baking…well anyways I definitely can conclude this is the organizations doing….
