Electronic enthusiasts may be interested in a new high voltage step-up converter offering from 5V to 900V maximum outputs, which are selectable using the provided jumpers or via 4 pin parallel interface. And optional oh LED module is also available allowing you to create a wide variety of different applications and projects. It’s creator Papadopol Lucian Ioan based in Gradara, Italy explains a little more about the inspiration design and features of the step-up converter module.
“In the first prototype I’ve easily reached 1650V of output but into the second (current) production prototype I could not exced 900V because of the insufficent spacing between HV multiplier and the MCU. This is not an issue because mostly all geiger tubes works with less than 900V.”
“The board is thought to be used as a module of a bigger project or stand alone. As module of a bigger project, you can simply omit the OLED display and connect the 8 pin connector to your project. The 4 bit parallel interface selects voltage output and the ACK pin goes HIGH when the output voltage selected is reached/stabilised.”
“If you wish to use the module as stand alone, you can connect the OLED and a geiger on the + and OUT pins, 5V supply from a battery (voltage regulator NOT included) and you can see the voltage, pulses per minute (CPM) and last minute reading on the display. The output voltage is selected by make a soldering bridge on voltage selection jumpers. It permit you to made a pocket size geiger counter with very low effort.
The step-up converter module and companion OLED module have this week been launched via Kickstarter with the aim of raising just €625 to make the jump into production.
