CTRL, THE INDUSTRIAL ROBOT ON YOUR DESKTOP

CTRL the robot is a desktop-sized robot arm that can do a lot! It enables your computer to perform manipulation of real objects via software and gives you access to technology that has been locked away in large corporations factories. CTRL was launched on a Kickstarter campaign that unfortunately didn’t reach its goal of AU$ 215,000. The early bird product was sold for AU$ 699 (~ $540) and you were able to ...

Reverse-engineering the surprisingly advanced ALU of the 8008 microprocessor

A computer's arithmetic-logic unit (ALU) is the heart of the processor, performing arithmetic and logic operations on data. If you've studied digital logic, you've probably learned how to combine simple binary adder circuits to build an ALU. However, the 8008's ALU uses clever logic circuits that can perform multiple operations efficiently. And unlike most 1970's microprocessors, the 8008 uses a complex car ...

INCREASING BATTERY LIFE WITH UB20M VOLTAGE DETECTOR

Engineers at the University of Bristol have developed a three terminal pico-power chip that can cut standby drain in sensor nodes – even compared with today’s low-power microcontrollers. It does this by replacing the low duty-cycle sleep-wake-sleep pattern used on MCU-based sensor monitors, with ‘off’. A voltage detector powered by the sensor – there is no other power source –  starts the processor when the ...

Peaktech 6225A review

I got a Peaktech 6225A power supply to power some things, as it seemed like a good deal, going beyond what one might find normally in these types of supplies: more display resolution and supposedly, lower noise. For this price, this supply is a good deal compared to other similar ones on the market. Let’s see how it performs. You can even grab one on Amazon.de or Amazon.frthrough affiliate links which helps ...

PSU Burner

Intro What does one do when designing a power supply? Well, build a power supply tester, of course. One of the simplest things to build is a constant current load. This will allow for testing of the endurance of the power supply, as most of the designs out there are using slow components. However, I wanted to make a better one: one that I could hook up to my Analog Discovery and generate a test waveform to ...

Latching Relay Module

In electronics, a device is said to be a latching device if it maintains any particular fixed state even after removal of the input signal. The same also applies for electronic/electromechanical relays. Basically the electromechanical relays that are used today are of two types: 1. Non-Latching Relay : These relays are most widely used where energy consumption is basically not an issue.This type relay(s) co ...

Why did I build a power bank?

Why would anyone even try to build a power bank - i.e. an external battery for charging mobile devices - these days? These things are commodity, it's impossible to compete. Right? Well, that is until you find out that the type of power bank for your application, namely charging a higher-end tablet with 12V input, does not exist cheaply. Looking around for 12V power banks yields a lot of li-ion car jumpstart ...
