Half Bridge Driver based on IR2104

Half-Bridge-Driver-IMG_4772

This Half-bridge driver based on IR2104 gate driver IC and N channel Dpak MOSFET , The IR2104 is a high voltage, high speed power MOSFET driver with independent high and low side referenced output channels. HVIC and latch immune CMOS technologies enable ruggedized monolithic construction. The logic input is compatible with standard COMOS or LSTTL output, down to 3.3V logic. A gate IR2104 driver is a power amplifier that accepts a low-power input from a controller IC and produces a high-current drive input for the gate of a high-power transistor such as a power MOSFET. In essence, a gate driver consists of a level shifter in combination with an amplifier.

This drive has many application, ranging from DC-DC power supply for high power density and efficiency, This project simplifies the design of control systems for a wide range of motor applications such as home appliances, industrial drives, DC brushed motors , Brushless motors, fans, Tesla Coil driver, Induction coil driver, LED driver, Halogen Lamp driver.

UP/DOWN counter with memory using PIC16F88

counter39

Here is an up-down counter based on PIC16F88 and 7-segment display. The counter is using SMD components and features a RS-232 interface.

This is a simple digital counter with a serial rs-232 and a 7 segment display, i started this project to count items on some shelfs, but it can be used for anything, it is also, for the exception of the connectors, completely on SMD components.

SMD Soldering Reflow Oven

F2FAAMTIM53QPAP.MEDIUM

Here is a nice tutorial on how to build your own reflow soldering oven using ControLeo2 reflow oven controller.

This particular instructable is based on the ControLeo2 reflow oven controller by Peter Easton. This is by far the best I’ve come across and the software is fully open source. It can control up to 4 solid state relays (SSRs), a servo motor (to open the door for cooling at the end of reflow process) and a buzzer. Most impressive is that it is self-learning. That means, it can adapt to your oven heating elements and their behavior. Thanks Peter for putting this out there! The electronics hardware design is based off Brian Barrett’s design. He is super helpful and I suggest reading his build guide (multiple times). Thanks Brian! 🙂

ESP8266 Breadboard Adapter

Gerber_View

Markus has designed a single-sided ESP-12/ ESP-07 breadboard adapter that uses easy to find SMD parts and has on-board voltage regulator.

Features:

* Fits ESP-12 and ESP-07 module
* Single-sided self-etchable design
* Few, cheap parts in SMD
* Breadboard-style – one row on each side accessible
* Vin >4.5V (max. 7V) input possible with 3V3 onboard voltage regulator (with two capacitors 10µF)
* Power-indicator LED
* (Schottky-) Diode as reverse polarity input protection possible (solder 0 Ohm resistor or just connect the two pads for no protection)
* RST, CH_PD, GPIO0 with 4k7 pull-up resistors on board (resistors can be omitted if remote access of those GPIOs is needed)
* GPIO15 with 4k7 pull-down (see above)
* Tactile switch connected to GPIO0 to get into flash mode
* Single post for 3.3V output near voltage regulator

Surface-mount device prototyping in education

smd_parts

In this article Vassilis K. Papanikolaou explains how SMD prototyping practice can be used in learning environments using simple and wide available tools and equipment:

A feasibility study is herein attempted, towards the adaptation of modern surface-mount device (SMD) prototyping practice to learning environments. This necessity emerges not only from the profound advantages of the above technology (e.g. component size, availability, low cost etc.) but also from the fact that contemporary designs often require special board layout considerations, which may be incompatible with through-hole components. In addition, the long process between prototyping and product finalization can be greatly shortened. Nevertheless, the employment of surface-mount techniques in education may be discouraged by both the unappealing part sizes (i.e. handling difficulty) and the excessive cost of commercial supporting equipment. The main objective of this study is to suggest practical and low-cost solutions for all different SMD prototyping/manufacturing stages, which can demystify and render this procedure welcome and easily applicable in laboratory classes.

Making A SMD Reflow Oven

FNN6TOQICID5EAF.MEDIUM

by packetbob @ instructables.com:

I decided to put together a toaster oven and wanted something that could handle large boards and possibly do small production runs. Doing a web search, you will find many options for toaster oven reflow controllers. They range from one-off designs to DIY boards to full kits. A large number of them are Arduino based. Some controllers just allow the oven to plug in (so you don’t need to take the oven apart) while others integrate completely inside the oven (more work but a much better product in the end).

An SMD 4 digit 7 segment DIY display

I was designing an electronic clock to see time easier at night. And while at it, I came up with a nice idea:

Having used a lot of perfboards(dot pcb) to prototype my projects, I thought of a way to make a 7 segment display out of smd leds. Making a segment out of 2 common grounded leds..
I stumbled upon it while trying to determine a nice size for my clock. I drew a mask on perfboard with a marker. Later I redrew it and cut it out:
