The IoT development platform that runs Python in real time, and features the perfect blend of power, friendliness and flexibility.
A small, super low power, inexpensive, and 100% Python programmable IoT development board. The WiPy takes the wireless freedom of WiFi and combines it with the power, flexibility, and ease of use of Python. We designed the WiPy from the ground up, with one goal in mind: “Let’s make IoT development fun both for beginners and professionals”.
- Inexpensive, small and breadboard friendly.
- Ultra low power (850uA with the WiFi connection active)
- 100% PYTHON PROGRAMMABLE.
- Lots of GPIOs, interfaces and peripherals.
- Powerful CPU and state of the art WiFi radio.

Moore’s Law, famous for predicting the exponential growth of computing power over 40 years, comes from a simple try-fail/succeed model of incremental improvement. The predictive success of Moore’s Law seems uncanny, so let’s take a closer look to get an idea of where it comes from.
Moore conceived his law for computational power but Moore’s-like growth laws permeate human endeavor—a fact that had never occurred to me until I went to a presentation by Lawrence Berkeley National Lab energy researcher, Robert van Buskirk. He showed several technologies that improve according to Moore’s law, but with different timescales than the original. You can read his paper here, notably co-authored by Nobel Laureate and former Secretary of the Department of Energy, Steven Chu.

Intel announced at CES 2015 the Broadwell family, its fifth-generation Core processors. The 14 new chips are essentially versions of the company’s 22nm Haswell architecture made in its new 14nm process, providing enhancements it hopes encourages PC and notebook users to upgrade.
Intel will offer dual and quad-core chips — 10 processors at 15W (both Core i5 and i7 chips) with Intel HD graphics, and four 28W products with Intel Iris Graphics spanning i3, i5, and i7 lines. The dual-core chips have 1.9 billion transistors, a 35% increase over the prior generation, and a 133 mm2 footprint that is approximately 50mm2 smaller than its predecessors. The 15W chips have data rates up to 3.1 GHz while 28W i7 cores hit up to 3.4 GHz.

Intel announced its 4004 processor and its chipset through an ad in Electronic News on November 15, 1971, making them the first complete CPU on one chip and the first commercially available microprocessor.
The building-block 4004 CPU held 2300 transistors. The microprocessor, the size of a little fingernail, delivered the same computing power as the first electronic computer built in 1946, which, in contrast, filled a room. Full technical details for the 4004 can be found in this January 1972 EDN story on the technology: One-Chip CPU available for low-cost dedicated computers.

Fujitsu Laboratories Ltd. today announced the development of a receiver circuit capable of receiving communications at 56 Gbps. This marks the world’s fastest data communications between CPUs equipped in next-generation servers. In recent years, raising data-processing speeds in servers has meant increasing CPU performance, together with boosting the speed of data communications between chips, such as CPUs. However, one obstacle to this has been improving the performance of the circuits that correct degraded waveforms in incoming signals. Fujitsu Laboratories has used a new “look-ahead” architecture in the circuit that compensates for quality degradation in incoming signals, parallelizing the processing and increasing the operating frequency for the circuit in order to double its speed. This technology holds the promise of increasing the performance of next-generation servers and supercomputers.

While working on an update for my CPU Usage LEDs project, I thought why not just make it into a universal RGB LED controller? The CPU Usage LEDs controller took a value between 0 and 255, worked out what colour it should be and then fade to that colour. This was very limiting; changing what colours it used and how it fades required a firmware update. With this universal RGB LED controller the host software does all the work and the controller is simply told what brightness the red, green and blue LEDs should be. To make it as easy as possible to interface with the controller I created a library which deals with all the LibUSB stuff.

This little device shows you the CPU-load, how much physical and virtual memory is used. It shows this data per 10% on 3 ledbars. To do so it uses a VCP (Virtual COM Port), so that it can be connected to a PC via a USB connection to receive the data. Collecting the data and sending it to the device is done by a Python script.

Ivan Creations made this ReCoMonB (Real Computer Monitoring Block) and wrote a detailed explanation on his blog describing the build:
I managed to de-virtualize the CPU/MEM/HDD/NET stats and now I have them physically represented on my desk. The device that does that is named ReCoMonB – Real Computer Monitoring Block. I have also made the device driverless and working on Liunx and Windows.

Now for something a little different. I was first exposed to computers back in the late 1970s and early 1980s. Suffice it to say, placing my hands on the keyboard of an Apple //+ was a watershed moment which pretty much set the course of my life from that point on. The heart of the Apple // was the 6502 microprocessor. I learned to program on that chip, along with millions of other people. It was the chip that brought computers and video games to hundreds of millions of homes and schools, and I think it’s safe to say that it sparked a revolution. The world was ready for personal computers, but all the contemporary CPU offerings (notably from Intel, AMD, and TI) were very expensive. The 6502 offered all the power of the others, for 1/10th of the price. You could find 6502s in the entire Apple // line (except the GS), the Commodore 64, the Vic-20, the Atari computers (except the ST), the BBC Micro & Acorn, the Atari 2600, the Nintendo Entertainment System, and many others. If you used a personal computer or played a videogame in the 1970s, 1980s, or early 1990s, there’s a very good chance it had a 6502 in it. It was arguably the first RISC chip, and the first to do pipelining. It has a clean, elegant instruction set and gets much more done with a clock cycle than anything else of the era.
