The Factors That Determine PCB Assembly Pricing

This is a sponsored post discussing about PCB assembly costs factors on Bittele Electronics. Bittele Electronics has developed its pricing schedule based on various factors that determine PCB assembly costs. Some of our customers call us to better understand the factors involved assembly pricing. In general, the factors that cause pricing differences include PCB dimensions, part types and quantities, solder ...

DIY USB to TTL Converter

Now that the PC’s com port or Serial port is almost obsolete there is quite a lot of requirement for USB to TTL or USB to RS232 converter. USB to TTL converters are required for interfacing microcontrollers to PC it is also required for loading code in Arduino Mini, setting/modifying ESP8266 firmware. Over here we are going to make a do it yourself (DIY) USB to TTL Module on a breadboard. Lots of USB to TTL ...

Smart LED Flashlight

How it works: The flashlight turns on automatic for 60 seconds when it senses that the room is dark enough. To turn on manual light for additional 60 seconds you need to push the RST button. The Light sensing LED Flashlight is invaluable for emergencies such as power failures or blackouts. Step 1: ​The Flashlight Is Invaluable for Emergencies Such As Power Failures or Blackouts. I have assembly several Flas ...

DIY 1GHz Active Probe For Under 20$

So, you're an electronics hobbyist and want a 1GHz* active probe, or a professional and tired of blowing your 2000$+ active probe in sketchy circuits when all you wanted to know are the whereabouts of some RF-signal? Then stay with me!! This Instructable will show you how to build a 1GHz* Fet-based Active Probe, the Fetprobe, for about 10$*, provided you have access to an electronics lab. It is based on an ...

Polyphonic Synth Cable

This is the fourth synthesizer cable I've built, the first three being based on the ATtiny85. I have been looking into ARM chips but haven't gotten to grips with them just yet. Instead, I decided go back to the ATtiny2313, which has a quarter of the memories of the tiny85, but a hardware UART port and more pins. It's quite a simple idea really - generate square waves by toggling the digital outputs on many ...

Making A SMD Reflow Oven

I have been an electronics hobbyist for many years and have always stuck with through-hole components when making a project. However as time goes by, not only are more and more components are becoming available only in SMD (surface mount device) but also more interesting projects are also SMD based. There are several options for doing your own SMD soldering: Hand Soldering - Using a fine-tipped soldering ir ...

The SMD beak

I ordered this awesome N|Watch kit the other day, which requires some serious SMD hand-soldering skills. There's always the easy alternative to use a reflow oven, but guess what, there is no stencil included (and no, I don't have a paste dispenser). In a desperate need of a third hand (!) in order do a neat job, I saw some similar DIY solutions (thumbs up for Google images) and managed to build my own versi ...

Print Your Own Circuit Boards and Reflow SMD Components with the Voltera V-One

Typically when electrical engineers wants to make a new circuitboard, they need to send their design files to a manufacturer and wait for it to be produced and mailed back. Hardware startup Voltera aims to expedite this process by putting it in on your desk with its V-One consumer circuit board printer. Winners of the $50,000 TechCrunch “Hardware Battlefield” at CES 2015, the Haxlr8r alumnus Canadian team h ...
