Nichrome and fuses melting at 1800x magnification – video
Recently I was asked by Joyalens to review their JL246MS digital microscope. I accepted in order to look at Nichrome and fuses up close. (Note I don’t receive any commissions for sales). Interestingly this microscope is USB 5v powered, so it’s easy to run even off of a battery pack if needed. Nichrome wire forms…

12V Toaster Oven! Build your own for about $25 DIY / HOW TO Video
12 volt toaster ovens should be very cheap and readily available – the world needs them. I’ve been working on a 12v DIY volt toaster oven prototype project for over a year in the solar workshop. Wouldn’t it be great if the DIY solar power enthusiast could build a portable 12 volt toaster oven in…

Direct Solar Electric Cooking vs. traditional methods – A Grid Down Scenario
It’s happened, The Grid Is Down. Roads are closed. No gas stations are open. Nothing works. Electrical power and communications are gone. Chaos is slowly breaking out. But the Off Gridder feels fairly secure; solar panels on the roof, 20kw of batteries, a wondrous integrated inverter with bluetooth, MPPT charger all crammed into one giant…

My 12 Volt Hotplate Cooktop Prototype – Cooking without an inverter
This project has the goal of the total conversion of a portable kitchen cooktop / hot plate to pure 12 volts DC operation – NO inverter! Second is to show and demonstrate that such an appliance should exist. I believe this type of 12 volt appliance should be common and affordable. With a 12 volt…

20 Watt Solar Panel Boils an Egg! My ultra efficient solar electric cooker prototype (Video Added)
Cooking food with only 10 watts of solar power sounds unattainable – but it’s not. This was recently proved in my solar workshop. I used a combination of an insulated food container with a diode chain solid state heating element to efficiently extract heat from a solar panel. The result is an ultra efficient mini…

Tiny 12V LiFePo4 Lithium Solar Powered Kitchen Setup – Emergency Preparedness Test
Cooking food from smaller solar power systems has always been one of my key interests. High tech survival and emergency preparedness too. But cooking with standard kitchen appliances often seems out of reach due to the high power draw required. And many people do not have large batteries and inverters to do the task. The…

Solar PV Solid-State heating elements (Diode Strings) explained
This post is mainly to address the lack of understanding about solar powered (PV-to-Load) solid-state heating elements – also called a diode string or chain. The Part 2 video presentation and this blog post should help fill in the blanks. The video itself is also posted here on this page. Watching Part 1 is also…

Boiling Diodes: a more efficient way to heat water and cook food using Solar Power
Why Solid State Solar Electric Heating Elements Matter Update: further research has been conducted into this topic, and it has been very fruitful. Videos showing some of the latest results are posted on this page. While continuing my research into solid-state solar electric PV-to-Load heating elements, I decided to try heating and if possible boiling…
