Pastures (grass fields) are not always connected to a house or an electrical circuit. Installing a 12V battery is a common solution to this problem. This comes with the risk that the battery runs out with further damaging. To solve this, I installed a microcontroller with a cellular connection next to the battery. This sends data readings to the custom API. The app consumes this API to visualize a chart. It also receives push notifications when the battery percentage is critically low.
Blockchain technology known from its cryptocurrencies is an unknown territory for most of us. Since the rise of the Bitcoin a lot of capital found it's way into cryptocurrencies. As a proof of concept, I created a lottery web app in Angular. This web app integrates with MetaMask, a cryptocurrency wallet plugin attached to the browser. In this web app participants of the lottery buy tickets and gamble on a number. The code that performs these crypto currency transfers is written in Solidity, a language made for the Etherium blockchain. Picking the winning number is real challenge, since blockchain technology relies on a network of nodes that execute the same code. Random is never truly random.
Users can't be asked what they want. That is why other techniques like, scenarios, prototyping and user testing exists. This design was made for researchers of sensory odor testing labs. Their job is to visualize differences in taste and smells of different products. The platform assists these researchers and avoids repetitive work.
Summaries of courses are thrown away every year in the summer, yet most courses rarely change. This platform was built to upload student written documents in PDF format. This enables all students to study with the summaries from the girl with the best handwriting in class. This platform was built using Laravel and Bootstrap for a faster delivery of the concept.
Creating a website is easy. Doing it right is harder. The international community that develops web standards provides a couple of validators. Every developer can use these validators to check if their HTML and CSS code is complied with the standards. In this project, 4 pages of an existing webshop were rebuilt from scratch and wrapped in a new design. All the code was validated to ensure better accessibility.
Local organizations usually have terrible websites, although their target audience requires the most user friendly website. KVLV Welden reached out to me and received a custom website. Together with Wordpress as a CMS and the Advanced Custom Fields plugin, the administrators can now easily add, edit and remove content. This allows the users to effortlessly register for activities every month.
