In this post, I’ll show you how to program the ESP32 Camera board to live stream the video feed to your browser.
In this post, I’ll show the portable 100W LED torch floodlight I made. I originally bought the 100W LED and lens kit many years ago but have just recently decided I would finally make an LED flashlight out of it. A lot of the flashlights online usually don’t have a very large battery capacity and need to be recharged quite often if you use them for an extended period. The problem is a lot of those flashlights also use 16850 batteries that have to be taken out of the flashlight to be recharged with a charger. This prompted me to create my own flashlight with a large battery capacity that is also easily rechargeable without having to take out the batteries every time.
In this post, I’ll show you a Raspberry Pi microscope I made for soldering and inspecting PCBs. The great thing about it is that it has a long working distance. This enables the microscope to be mounted on the shelf above my workbench so it doesn’t get in the way. An additional benefit is that the image doesn’t shake if you bump the table when working.
In this post I will document some of my smaller projects that don’t deserve a whole blog post of their own.
In this post, I’ll show you how to make a cheap portable spectrum analyzer from a TV receiver dongle. The dongle gets sold as a TV (DVB-T) however its an SDR(software defined radio) which means that it can be used to receive pretty much any RF signal(depending on the chip used up to 1-2 GHz) and turn it into a digital one to be later processed by software.
In this post, I’ll show you my DIY FPV goggles. These obviously aren’t as good as proper FPV goggles but they are cheap, they work and I was able to make them out of things I already had at home.
In this post, I’ll show you a handheld induction heater I made. I bought the ZVS driver circuit board and coil quite some time ago but I just recently saw someone made a very neat 3d printed case for it on thingiverse and decided to make a handheld induction heater out of it. This one is smaller and much less bulky than the other one I made wrote about in this post.
In this post, I’ll show you the induction heater I made. I bought board and coil as it’s easier and quicker than making it on your own. It’s rated for 2000W but the maximum power I can get out of it is 1200W because that’s as much as the power supply I’m using can supply.
In this post, I’ll show you how to make a signal generator and oscilloscope from a PC soundcard. I used a cheap USB soundcard so in case the input voltage gets too high, I don’t damage my PC. This signal generator and oscilloscope obviously don’t have the best specs and are very limited. They can produce/measure a very narrow range of voltages and frequencies(0-20KHz).
Recently I decided to clean up my project backlog by either finishing or scraping the projects. A lot of times when I start something it eventually ends up being sidelined for months(or even years) for a multitude of reasons (being busy with other stuff, waiting for parts, forgetting about them, not feeling like it). In this post, I will document some of the ones that I decided to cancel/scrap, how far along I got and the reason I started the project in the first place and why scrapped it.
