Adding 6 panels to my garage roof—€1,350 total, with 3.5 years projected ROI. Since I already have a hybrid inverter and home battery, taking advantage of the empty roof space right above it was a no-brainer. That price covers all materials (optimizers, DC/PE wiring, etc) and I will install myself

I added undervoltage and over current protection to my linear solar harvesting into lithium ion capacitor board. www.tindie.com/products/jas...

My Solar Linear Lithium-Ion Capacitor Charger Board is now available on SmallRun. Designed for efficiently charging LICs from a solar panel using a simple linear approach. This board is ideal for low-cost outdoor applications. smallrun.net/shop/jaspers...
I designed and ordered 100 pcs of the V2 revision of my linear solar charging circuit for lithium-ion capacitors from JLCPCB. The new version adds 2.5V undervoltage and 3A over current protection. www.tindie.com/products/jas...
Outdoors this linear lithium ion capacitor charge board outperforms switching alternatives. When combined with a 5V solar panel, the efficiency is actually higher. I need to add under voltage protection to make it better. www.tindie.com/products/jas...

DIT is waar Kamerleden zich mee bezig horen te houden: Wetgeving. (Niet met uiterlijke schijngevechten, elkaar vliegen afvangen en voortdurende campagne.) ‘Lisa Vliegenthart (PRO) dient initiatiefwetsvoorstel in om abortus uit het strafrecht te halen.’ 👏
Oppositiepartij Pro wil abortus uit Wetboek van Strafrecht halen

Goede uitleg over de kamerthermostaat terwijl je ook een stooklijn hebt. youtu.be/lPV0fv4wgxQ?...
Wat een stomme titel. Een warmtepomp is wel het goedkoopst en het meest duurzaam. Energierekening stijgt de komende jaren, vooral voor mensen met warmtepomp - nos.nl/l/2630491

New study finds the social cost of driving a car 1 km—including pollution, crashes, infrastructure, and noise—is more than *triple* the private cost paid by the car owner. doi.org/10.1016/j.tr...
