Top-level Weller soldering stations for even better prices

obr1252_5

Now even you can afford the best, what´s available on the field of soldering and service.

A fact, that we also try to transform better purchasing conditions on You – our customers, we´ve already mentioned to you few times in our articles. This time we have this pleasant occasion to make so at soldering equipment from company Weller. The biggest change happened at components, which are usually the most costly – at soldering (and desoldering) stations.

The result is lower price at all Weller stations, which are our standard stock items – in majority of cases in 15-20%, what makes up to 200-300 Eur discount at the most expensive types.

It´s still actual, that within 1-2 weeks we´re able to supply you practically any Weller component (which we don´t keep in stock). In our offer can also be found selected types of original soldering tips and any other types can be supplied to you in a short leadtime and at convenient conditions.

So where to start? Probably best by having a look at the Weller catalogue. Our previous articles may also give you an inspiration.

Unlock a Door with your Fingerprint

FGZ9JKTIFPOL0KL.MEDIUM

by Kinoma @ instructables.com:

We built a biometric fingerprint-controlled lock prototype. A fingerprint scanner is used to capture and store the fingerprints of authorized users. When the scanner recognizes a user, a solenoid plunger disengages and opens the lock.

How to program the ATtiny85 with the Arduino UNO board

FBKHKPPIFMTRL67.MEDIUM

by codebender_cc @ instructables.com:

In this tutorial we will use an Arduino board as an ATtiny programmer.

To do this we will use one Arduino UNO board as an ISP (programmer) and one ATtiny85 micro-controller.

We will use Codebender – online Arduino IDE.

With the following procedure you will be able to program easily the ATtiny45 and ATtiny85 micro-controllers.

Home automation with Telegram BOT

by lucadentella.it:

The project I’m going to describe today it’s a sort of proof of concept that will demonstrate the possibility to remote control sensors and actuators (for example a couple of relays) via Telegram.

Telegram is an instant messaging application, similar to the famous Whatsapp. Last June, the Telegram developers announced that a new set of APIs were available to develop bots.

Simple, Cheap Motor Controller

F14DG4NIFMVWEV9.MEDIUM

by TeamJaeger @ instructables.com:

I’ve used this simple circuit several times to drive motors (like in my Stair Climbing robot) as well as solenoids. I originally picked it up from this instructable which is focused on controlling a solenoid. I wanted to isolate this circuit in its own Instructable as a motor driver so I could easily reference it from other future instructables and also provide example code to show how to use it in this manner.

Arduino Thermometer With DS18B20

FKFWTTMIFMRO4GY.MEDIUM

by KonstantinDimitrov @ instructables.com

Hello, everyone !!! Today I’m going to show you how to make Arduino thermometer with DS18B20 digital temperature sensor, builded on breadboard and connected together with jumpers.

Info about the sensor – DS18B20 is 1-Wire digital temperature sensor from Maxim IC. Reports degrees C with 9 to 12-bit precision, -55C to 125C (+/-0.5C). Each sensor has a unique 64-Bit Serial number etched into it – allows for a huge number of sensors to be used on one data bus.

IP Time Clock using NTP protocol

FZPPJHVIFO94519.MEDIUM

by msuzuki777 @ www.instructables.com

So this Lazy Old Geek (LOG) has a couple of clocks in my bedroom. One of them loses time when the power is lost. The other is semi smart and automatically adjusts for Daylight Savings Time. Unfortunately, it does this using the old standard so I have to re-set the time four times a year. Well, I’m LAZY so I decided to make my own Clock. At first I was thinking Atomic clock as I have three in my living room (I’m a GEEK, remember?).

USB PIC Programmer

DSCF2014-1024x768Stefano Purchiaroni rebuild a USB PIC Programmer that he found online. He writes:

This page is dedicated to everybody needs to program a PIC (Microchip) device via USB port. Looking on the web for ready-to-use projects, I found a good one called Open Programmer, coming with several schematics, PCBs and Open Source code. The original link is http://openprog.altervista.org/OP_ita.html

What concerned me was the need to mount, on the mainboard, a specific socket board depending on the model of PIC being programmed. Moreover, the proposed layout did not meet my personal “compact look” ideas. So, I propose hereafter a small layout version of that circuit, adopting a single smart on-board ZIF socket. This version sacrifices many non-PIC microcontroller models. I will thank everybody proposing a larger range implementation, suitable to program Atmel and other devices. Anyway, if your goal is to program PIC devices, you are on the good site.

A small box, a USB connector, a ZIF socket, two leds. That’all in my compact proposal.

Large Current Relay Driver

I045A

This is a large current Relay module with single pole double throw switch which provides normally closed and normally open operations. The Relay is the most common used module in application such as home automation, industrial automation, and machine on/off. Sometimes you need to control large current such as the fans, lights, water heaters, room heaters, Air-conditioning, vacuum pumps That is what this Large Current Relay Module can be helpful to drive such high current load with just TTL signal. Easy interface with embedded systems and micro-controllers.

Features

  • Supply 12V DC
  • Current 190mA
  • Trigger Supply 3 to 8V DC
  • Optically isolated input for safety and noise immunity
  • 7 Pin Header for Inputs and 5V DC output
  • 3 Pin screw Terminals for Relay output
