Simple Mosfet tester N-type

TehnikService — Sun, 29 Aug 2010 12:28:31 +0000

When you make MOSFET assemblies with especially when they are retrieved must be checked before assembly. This may seem very simple checker can check all N-type MOS-FET.

DIY TV-B-Gone Micro

TehnikService — Sun, 29 Aug 2010 12:21:35 +0000

The TV-B-Gone is a neat little device that can turn almost any TV on or off. It uses a microcontroller hooked up to IR LEDs to output a library of on/off codes. Adafruit sells a kit, and has the code as well as the schematic on their website.

Here’s a micro clone of the TV-B-Gone that runs on a coin cell battery, is slightly bigger than a quarter, and costs about $3.50 (compared to $20) to make!

iCircuit Simulator for iPhone

TehnikService — Tue, 17 Aug 2010 23:23:37 +0000

iCircuit is the premier iPad and iPhone app for designing and experimenting with circuits. Its advanced simulation engine can handle both analog and digital circuits and features realtime always-on analysis. It is the perfect companion to students, hobbyists, and engineers.

You use it as you would any CAD program: you add elements, connect them together, and set their properties.

But iCircuit is unlike other CAD programs because it is always simulating. It’s just like working with the real circuit. You do not stop to take a measurement or spend a lot of time configuring reports. Instead, you just play with the circuit as you normally would, with the power on!

There are over 30 elements you can use to build your circuits. The app has everything from simple resistors, to switches, to MOSFETS, to digital gates.

You use it as you would any CAD program: you add elements, connect them together, and set their properties.

Nursery Room Temperature Monitor

TehnikService — Mon, 02 Aug 2010 12:00:31 +0000

The idea was to utilize a diffused RGB LED, an analog temperature sensor (really wanted to expand my working knowledge of the ADC on AVRs) and a frosted glass sphere to create a highly visible temperature indicator. I quickly sorted through my parts bins and found most of what I would need. A quick search on eBay and a short drive to Lowe’s provided the rest.

Picture Frame with PIC 24HJ256GP206

TehnikService — Tue, 20 Jul 2010 21:58:33 +0000

This project is based on PIC 24HJ256GP206 processor and add a dash of knock-off touchscreen and a pinch of SD card compatibility for a DIY digital picture frame. [Daniel] wrote his own driver for the HX8347 controlled LCD that can achieve 15 FPS at 320×240 resolution with 16-bit color. As this was a gift for his wife, [Daniel] included a heart-shaped ring of LEDs that fade in and out like an electronic pulse.

Homemade PCB (Etching)

TehnikService — Thu, 15 Jul 2010 22:12:30 +0000

The goal of this tutorial is to teach you how to take a circuit drawn in a fabrication program like Altium or Eagle and make it a real-life PCB. To accomplish this we will need about $20-25 and a few hours of spare time.

Adding Custom Graphics to EAGLE PCB Layouts

TehnikService — Thu, 15 Jul 2010 20:31:38 +0000

The objective of this instructable is to show you how to add custom graphics to a PCB using EAGLE Layout Editor. You might want to add a logo or your website address to an electronics PCB that you have created. I found out that the process of adding images to a PCB was not trivial or obvious. In order to save everyone some time, I have listed out the process.
