First of all, please watch the video below to find out how everything was done on my work bench. A recent project requires soldering 600+ tiny LEDs on long narrow…
I am working on a DIY PCB project that requires mounting three PICOR PI3301 Power regulators. Unfortunately, the PI3301 comes with a high density 123-pin LGA footprint in a 10mm…
Bootloader must be designed to be very reliable. In other word, bootloader is an unsung hero carrying out its job when necessary. It shouldn’t be replaced or destroyed at anytime.…
The “copper to drill hole” distance is an important rule for circuit board design, just like the “copper to copper” clearance. A PCB manufacturer usually announce their minimum allowable clearance…
Owning 3D printers with different nozzle diameters, I am able to give some first-hand experience on their advantage and disadvantage. Hope these could be helpful. FYI, my 0.4mm printer nozzle…
If you have read my previous post about how to extract useful data from INTE HEX32 format hex file, you are just one step away from being able to burn…
A big improvement of dsPIC33e series micro-controller from its predecessors is the re-mappable peripheral IO. This allows great flexibility for circuit board design, but also requires slightly more efforts to use…
First of all, let’s take a look at the video clip below (link) to find out how it is possible to reflow solder components without stencils. I talked about DIY your…
First of all, let’s check out how easy and sweet it is to remove the supportive raft from your 3D print. All you need to do is just to follow…
First of all, let’s see the video of the heated print bed in action! This table is built for Type A Machine 3D printer, but it should works for all…
