  • Neue Spiele sind eh doof. Hab neulich Teufel darf weinen 5 wieder zurückgegeben, weil es im Jahre unseres Herren 2019 zu viel verlangt war, dass man Zwischensequenzen dieses Spiels pausieren kann. 🙄

    Lieber die Wii-Version von Pikmin mit Bewegungssteuerung auf dem Steam-Deck mit Delphin. Richtig tolles Retro-Nintendospiel (und nicht das 1000ste mal Zelda… das kam vorher im PC-Port mit HD-Texturen und moderner Steuerung…)






  • I haven’t tested it yet in the field, but according to my USB-measurement device, a heltec t114 used less than a milliwatt (about 50uA at 5V => 0.25mW).

    According to a web search I did, the worst you can expect for a cheap solar module is about 10W/m^2. For a small panel with 3cm x 5cm, that’s 161mW.

    So, I think it should suffice. But maybe I should solder a bit and actually test my solar-node.

    Put I’m hardly the first one to try this.

    Edit: So, apparently, 50uA is a bit too optimisic. But some guy on youtube measured it at at 20mA worst case on 3.7V. That’s still 74mW.


  • Some people buy a cheap solar-powered led-spotlight for the garden. I got one for arount 8€ from aliexpress. Already water-thight, with a solar module and a battery.

    Then, add something similar to a heltec t114. It’s a bit more expensive than a heltec v3, but can actually be driven with a puny solar module from the garden light.

    You’ll also need to drill a hole for the antenna into the enclosure and seal it with silicone.
