Long time ago QVC sold a shakeable Flashlight that had no batteries just a shakeable generator and a super capacitor. This flashlight uses a 5vdc 1.5a wall wart to charge the capacitors. To figure out how long it will take to charge the flashlight you use this equation $$T=5R_{currentlimit}C$$ And for total discharge time $$T=5R_{LED}C$$ …
In this blog post a crt TV a part and turn it into a oscilloscope. I am going to try to use a TL082 op amp to buffer and amplify the signal. It uses the deflection yoke to draw the picture on the tube. More pictures and videos will be posted here when it is …
This wrist strap prevents electrostatic discharge to whatever you touch What you need: 1 meg ohm resistor(any wattage or tolerance will do Copper tape or foil a piece of wire(you can use all of the wires from a btoken cord if you like0 bracelet(This should allow the copper tape to stick) one alligator clip Step …
This is a very simple esd mat that anyone can build. All you need is Small nail Cardboard box A three prong cord(must be three prong so that it functions correctly) Copper foil sheets that stick(i got mine from eBay, it is used for guitars) 1 meg ohm resistor any wattage should do. Hot glue …
In this post I will show you how to make a analog computer using just resistors, switches and a 100 micro ammeter. Here’s the schematic of it: You can see the idea on how this analog computer works, it uses ohms law to get current from resistors in the circuits. Each current is limited in …
This screensaver does exactly what the name says. It looks for icons and have them bounce around the screen and leaving a trail behind them. They are randomly chosen from windows, system and cursors directory. It uses ExtractIcon function from shell32.dll to get the icon and number of icons.
This screensaver randomly chooses screensavers when it starts. You can choose which folders to use, how long of a delay between screensavers and which ones you don’t want running.
I wanted soundtap to keep recording after a song was done playing on YouTube so thus AutoRecord tool was made
This tool allows you to convert text files from one to another, making them compatible with different programs and operating systems. Linux most likely uses UTF-8 and Windows uses ANSI
This tool allows you to force safe search on Google, Bing,DuckDuckGo and YouTube. It even has a website blocker. It should even work on linux systems via wine. You can set it up through the network via network drive. Export ALSO MAKE SURE TO RUN AS ADMINISTRATOR.
