This is just a rough documentation for this project of mine. Schematic: Not found on the schematic and picture but the latest one has 100nF and 10uF on the 5v pin. Board: D16 – SW1 (Use internal pull-up)D17 – SW2 (Use internal pull-up)D21 – SW3 (Use internal pull-up)D22 – SW4 (Use internal pull-up)D23 – SW5…
This is just a quick entry to my project for additional information. Underneath this green board, there is the header for the built-in Arduino Leonardo of the Lattepanda Alpha. This board is for the fans and fingerprint sensor. I made a simple Python script to communicate with the Arduino Leonardo using pySerial to adjust the…
Hello, world! It’s been so long since I last posted something but here I go. As the the title says, this trip was back in 2019. They were still constructing some things at that time. Not sure about the current state of the place right now. It’s been 2 years so there are probably new…
Do you need more keys in a keypad for your projects? You can use an Xbox chatpad. It is sort of a complete keyboard. I actually got the idea from The Ben Heck show(It is now called element14 presents): His chatpad has a PIC microcontroller on it that could be reprogrammed if you got a…
We went to the 2nd day of the Big Bad Wolf 2020 at around 12am. Compared to last time, the book selection, for me, is better even though the allotted space for the event is smaller. Before, the cashier counters were outside the book sale itself. I think even the number of food stalls outside…
So what’s a Pmod? Basically these are modules that you will just plug that follows the Pmod interface specifications. You can browse Pmods by Digilent here. You could plug these into microcontroller boards or FPGA boards that supports the standard. What I followed is the Pmod Interface Type 1A which utilizes all the GPIO on…
As I have written about my desktop and laptop. What about my phone? The most I have access to compared to the other two. My phone is a Xiaomi Mi A1. It has the same hardware with the Xiaomi Mi 5x. The only difference is the software. The Mi A1 is an Android One phone.…
I want to talk about a CPU that I designed way back in 2016. I implemented it in C as a VM. A friend of mine, Bjørn is the one who made an assembler for it which is written in F#. Periwinkle is an OISC as opposed to RISC and CISC. It also has no…
I’ve always wanted to have a 3D printer. What I got is the Ender 3 made by Creality. I actually bought it in September from Makerlab Electronics via Shopee for 9,999php. I was eyeing for this model for a long time. I didn’t only get the 3d printer itself but also purchased some PLA filaments(gray,…
This was when my family came to Metro Manila to see me last week. We decided to eat in Sambokojin at SM Megamall. I haven’t included all pictures that I took because some of them are blurry. Well, even some of the included ones are blurry. I just want to share some pictures that I…
