This is update to AVR programmer. The schematics is a little changed now to include a ISP header, pin header for breadboarding with two GND/VCC so that power problems cant […]
PCB making process update: Easy PCB at home
The process in which I used to make PCBs at home has changed a lot in these recent months. Now I use Eagle CAD program to draw the board designs. […]
Making SMD PCBs at home: Quick PSoC3 board built
Few months ago, I've showed how to make PCBs. The process is unchanged just I've started using inkjet photo papers for best transfers especially in case of SMD designs. One […]
Homemade DC Soldering iron driver
There are a nice type of soldering iron in the market. It's a DC one. The iron rated at 12V/8W works fine in 9~15V range and gives adjusted temperature. There […]
NAND, OR and XOR device detection through gate test
The following gallery is of Gate test of logic ICs.I was given three ICs that were NAND, OR and XOR IC. And I had to identify them on basis of […]
Atmega8 based Voltmeter Ampmeter v2
This is V2 update of Atmega8 Volt-Ammeter. This new version features the following upgrades, Low power consumption Better Amperes display resolution while using low value drop resistor. Much smaller PCB […]
Yet another regulated power supply board
This is just a basic demo board of 78XX IC and LM317. LM 7805 and LM7812 are used here as 5V and 12V regulators. The supply for this board is […]
PCB update: Atmega8 Volt-Ammeter and USB AVR programmer
This is PCB update time. Few days ago I shared two projects made on veroboard. In these days, I have developed PCBs for those. Atmega8 based Voltmeter Ammeter for solar […]
Atmega8 based Voltmeter Ammeter for solar application
This project uses the ADC feature of a popular AVR, Atmega8. Atmega8 based Voltmeter Ammeter used Component List: 1x Atmega8- Programmed microcontroller 1x 1×16 LCD with Green Backlight 1x High quality […]
Simplest USB AVR programmer
I don’t have desktop with legacy ports and don’t like going to friend’s home every time I need to download something to an AVR. I asked myself “how can i […]
