  • Nice bright display

    posted byKmoer on 03/03/2018

    Nice bright and good-sized display, fairly easy to control once you have the right driver (TM1637Display for Arduino). Used it to upgrade a control box for a ceramic oven I revived, to show temperature and to handle UI for programming. Pros: good... Read more

  • Convenient module for small IoT projects with external antenna input

    posted byKmoer on 03/03/2018

    Made an IoT energy indicator of it; it connects to my Raspberry MQTT server and smart electricity meter. The color indicates my home's power consumption on that moment, at 10 seconds intervals. Build it into a small box, together with a LED power... Read more

    Impression: Nice and compact,easy to program,Good for small IoT projects;

  • Good for very flat ceiling light

    posted byKmoer on 12/27/2015

    Wanted an ultra-flat light for my utility room, as the headroom is low. Used two of these rings connected in parallel to a single 300 mA power source, so they effectively run at half power, reducing heat. Mounted with heat paste on aluminium also... Read more

  • Good regulator for power LEDs

    posted byKmoer on 03/23/2015

    Used this as a constant current source for an 3 Watt IR LED, regulating 5V/600 mA down to 1.6V/1.75A; way more efficient than resistor-based approaches of others. Runs fairly cool, indicating good efficiency. Pros: Good efficiency, compact form, a... Read more

  • Nice bright LED strip

    posted byKmoer on 01/15/2014

    Nice bright light strip, easy to split (needed to go around corners, you can strip the plastic relative easily and resolder wires on it). Seems to have some kind of thermal protection: at too much currents LED sections switch temporarily off see I... Read more
