Volterman, Your Personal Smart Wallet

With the rapid growth of technology, smartphones and e-payments are replacing cards, cash, and wallets. However, developers are still trying to keep wallets relevant in the 21st century, and Volterman is the newest attempts. Besides WiFi hotspot and power bank, Volterman also provides novel security features to protect your phone and wallet from loss.

Similar to other smart wallets, Volterman has a GPS tracking capability, so you can find it easily in case it lost. Through Bluetooth connectivity, it connects to the smartphone to ensure that you will not forget one of them. An alarm will start ringing to notify you and pick up what you have missed.

The new innovative idea on Volterman is a small built-in camera. It captures everyone trying to open the wallet while “lost mode” is running. The pictures are sent directly to the paired smartphone, meaning that you will know who is using your wallet and where is he. With an embedded SIM card, you are also able to track your wallet via the website.

Volterman’s Embedded System Specification

Inside the wallet, there is a full computing system to do all the stuff. The main components are:

  • CPU: ARM Cortex A9
  • Memory: 512MB RAM, and 32GB ROM
  • SD card: 64GB embedded card
  • Bluetooth: 5.0
  • Camera: 4MP
  • Mobile Network: Worldwide 2G, 3G
  • Wi-Fi: 802.11 BGN, Hotspot
  • GPS: A-GPS, GLONASS
  • Connector: magnetic connecter by Volterman
  • Power Bank: 2000mA, 2600mA, 5000mA, in addition to the capability of wireless charging.
  • Input voltage: 5V, 1A
  • Output voltage: 5V, 500mA

An interesting point is that the purchase price is covering the data charges for the GPS tracking and sending of photos to the Volterman server. According to the makers, Volterman will automatically connect to local networks in 98 countries, but at the moment the exact tariffs from country to country are unclear. However, it is offering up to 3 times cheaper internet cost than the regular price, with an early estimate of around $15 per 1 GB.

The Volterman comes in three different sizes: a small cardholder model $98 with 2,000-mAh power bank, a conventional bifold wallet $135 with 2,600-mAh power bank, or a larger travel size $157 designed to hold more cards, a passport and with a 5,000-mAh power bank.

After reaching more than one million dollars on IndieGoGo, Volterman is now ready for mass production and estimated to start shipping and the first quarter of 2018.

DIY USB 5V Solar Power Bank

Abdulgafur tipped us with his latest project, a 5V solar powered power bank. The circuit consists of two stages, the first stage is the battery charger stage based on MCP73831 and the second stage is the step up converter based on LT1302-5 which converts the battery voltage to 5V.

Solar energy is renewable, free, widely available and clean form of energy. It is considered as a serious source of energy for many years because of the vast amounts of energy that is made freely available, if harnessed by modern technology. Many people are familiar with so-called photovoltaic cells, or solar panels, found on things like spacecraft, rooftops, and handheld calculators. The cells are made of semiconductor materials like those found in computer chips. When sunlight hits the cells, it knocks electrons loose from their atoms. As the electrons flow through the cell, they generate electricity. In this project, we are building a power bank which harvests energy by using a solar panel.
