Add VGA & audio interfaces to a Raspberry Pi Zero

Add VGA & audio interfaces to a Raspberry Pi Zero

Some people need a thousand words to say something simple and still you have no clue what they’re on about. Others manage to explain a complicated thing in only a few words. This project is probably the project with the shortest description at Elektor Labs, but then again, why use many words when it is all about images? True, there are some illustrations too.

Connect to a WPA/WPA2 enterprise network using an ESP32

Connect to a WPA/WPA2 enterprise network using an ESP32

Connecting custom hardware to Wi-Fi networks employing the WPA security protocol — as do most home networks — has become a routine operation for many electronics hobbyists; besides the network’s SSID and the pass phrase, no other knowledge is required to get online. But how do you go about when you want to connect to a WPA2 protected network as used by many companies and universities for instance? Here is how.

Build a digital music platform or use it for something else

Build a digital music platform or use it for something else

We start 2019 with an Elektor project that although almost five years old still is interesting for (music-making) microcontroller enthusiasts. Why? Because the J²B Synthesizer is a flexible open source and hardware platform with many features and possibilities that can easily be transformed in something other than a music synthesizer. It even comes with an enclosure.

Raspberry Pi Buffer Board ready for ordering on GroupGets

Raspberry Pi Buffer Board ready for ordering on GroupGets

The ElektorLabs-designed Raspberry Pi Buffer Board protects your Raspberry Pi’s extension connections against damage from hardware errors like overvoltages or overcurrent. The board comes in two shapes: rectangular and 'T'. The rectangular version (PCB no. 150719-1) is now available for ordering on the group buying platform GroupGets. If 100 boards or more are requested/ordered/funded, Elektor will launch a production run.

Build an Xmas Countdown Display with The Raspberry Pi Ruler Gadget

Build an Xmas Countdown Display with The Raspberry Pi Ruler Gadget

Inspiring people, that is what we try to do here at Elektor. It doesn’t always work, but when it happens, and we hear about it, we feel that warm glow of happiness grow inside our bodies; a glow quite similar to the one that appears when drinking mulled wine (a.k.a glühwein) in December (or any other alcoholic beverage any time of the year). This week’s project combines inspiration & creativity, Raspberry Pi and mulled wine into an original Christmas decoration.

Build a GPS tracker for ultra-endurance cyclists

Build a GPS tracker for ultra-endurance cyclists

Ultra-endurance cycling races with distances of several thousands of kilometres are becoming more and more popular. During such races cyclists ride for at least 16 hours a day. Some of these races require validation by a GPS track but how to keep it up and running all the time? The purpose of this project is to build a very low-power, simple GPS tracker that can run unattended for days at a time on a single battery charge.

Build a simple MCU prototyping system

Build a simple MCU prototyping system

Here is an idea that is not new, but that pops up every now and then, and always due to the observation that because microcontroller systems often have things in common — like a display or pushbuttons — wouldn’t it be possible to come up with one design that fits all? Probably not, but here is a new attempt anyway, this time based on 18-pin PIC devices.

Build your own (fitness) tracker

Build your own (fitness) tracker

OK, so the design of this fitness tracker isn't quite as sleek as that of commercial products, but unlike those gadgets with 3-digit price tags this one is highly customizable. Not only is it up to you to design a suitable enclosure (or not) for it, what you put inside is for you to decide too. The basic version comes with GPS and OLED display and it does track your movements.

Pollux, a Raspberry-Pi-based universal intercom front end

Pollux, a Raspberry-Pi-based universal intercom front end

What do ships, factories and security services have in common? Several different and incompatible communication systems to control and secure one site. Indeed, VHF radios, telephones, intercom systems and more are all used together to communicate with the different services, rooms and departments in a building or on a site. Pollux provides a single front-end for all these communication systems.

DALI: industry's best kept secret

DALI: industry's best kept secret

Many microcontrollers have application examples for the Digital Addressable Lighting Interface or DALI standard intended to make equipment from different manufacturers interoperate smoothly. However, DIY projects exploiting this lighting control protocol seem inexistent. The project highlighted this week is about DALI, but it is not complete, and maybe even abandoned. Can you help out?
