So far, I’ve documented the original FPGA-based project and the framework used to turn it into an actual Application Specific Integrated Circuit (ASIC), along with its functional description in Part 1. In Part 2, I covered a few key design considerations I learnt as a beginner when transitioning from FPGA to ASIC, specifically related to … Continue reading RGBW Controller ASIC Part 3 – Design for silicon, colour space conversion algorithm and final block diagram
Things must come to an end. I decided to make a new library experiment, putting an ending mark to the DS1307 Real Time Clock hacking project, because the project was born as an encapsulation of a real RTC in a PIC microcontroller, wrapping an RTC hardware engine to emulate the DS1307; then a subsequent development on … Continue reading DS1307 RTC Emulator – The Arduino library
I have spent a lot of time on playing and later working on the I2C buses. I almost always used self developed libraries, both for learning and job requirement purposes. Then, when experimenting with a portability of a project in the Arduino environment, I started to trying the official Wire library, discovering some incompatibilities for my … Continue reading HardWire, the enhanced Arduino Wire library
It has been a while since the last LED related article. Was experimented the linear current source, its pros and cons and the field of application. Now arises the need of a small version, handling the same high power, things that are contrapposed in the linear regulator. I need something that I can bring with … Continue reading Tiny, robust, low cost, fail-safe LED driver: the Glighter-S project
Maybe some of you knows well the so called GertDuino, an expansion board of the RaspberryPi. It is like an Arduino which can communicate with the Rasp, and moreover it also mount an Atmega48 which can be used to emulate an RTC. Yes, I'm going to talk about this. The challenge: proof-of-concept of commercial real … Continue reading DS1307 Real Time Clock hacking: the emulation
If you like playing with lab instruments, enjoy to make things and design electronic stuff, you are probably attracted from the idea of create a new powerful (with some limitations) bench power supply by using an old ATX supply. Moreover, I need an high power supply to test my motors. For sure, building your own … Continue reading The classic hardware hacking: ATX power supply
