An Arduino-compatible smart outlet designed to instantly turn your toaster oven into a reflow soldering station.

Advances in technology continue to shrink the size of components. Hobbyists, who have traditionally worked with through-hole parts, are finding these parts harder and harder to come by as more parts become unavailable in through-hole variants.

Soldering surface mount components with a soldering iron, while possible, can be a rather tedious task. In particular, when you’re working with densely packed pins like those of a microcontroller, hand soldering a board quickly becomes a daunting task.

The Si7005 is a digital relative humidity and temperature sensor from Silicon Labs. It integrates fully factory-calibrated humidity and temperature sensor elements with an analog to digital converter, signal processing and an I2C host interface in a single monolithic CMOS sensor IC. The Si7005 is available in a “non hand-assembly-friendly” 4×4 mm QFN package, which requires reflow soldering to mount it on a PCB

Hi, I recently built a reflow toaster oven using an Arduino. I know it’s pretty standard stuff, but my version has an automatic oven door opener (using a servo) and circulation fan to speed up the cooling time, and remote notification using an RF transmitter

HP Pavilion DV9000 – DV9500 Series GPU Reflow FIX. This video shows how to repair Nvidia GPU issue on HP Pavilion DV9000 series laptop. In this video you see a DV9500 motherboard, this laptop had a completely black screen that fixed using this method.

Other common symptoms are:

- Black Screen
- Vertical – Horizontal lines
- Color flashes
- image distortion
- Laptop power off
- RGB lines

They say you are only as good as your tools. This is a statement I can vouch for, as better tools can make the difference between a sleek and well designed prototype and a rats nest covered breadboard. Unfortunately as an electronic hobbyist you don’t always have the budget of a big tech company at your disposal. But hey, that’s what DIY projects are for!

Starting off as a hobbyist or even small tech company designing and building electronics you will soon learn that most of the fun IC or MCU chips are either cheaper in, or only available in, surface mount form, and fancy reflow ovens are expensive.  But a soldering oven isn’t much different from a toaster oven–  the only difference is the accuracy and temperature settings.

That is why I’m going to show you how to build your very own Soldering Reflow Oven for under $100 from an old/new standard toaster oven, thermocouple and a microcontroller.

Sorry for the lack of photos in this article, but we didn’t think about it being worth reporting until after it had all happened. Infact, we were concerned about retaining any evidence of the events. Inspired by the many toaster-oven reflow projects floating around the Internet, we set out to acquire the power to solder all those tiny SMD components ourselves. Toaster ovens aren’t that common in the UK and we were aiming for the lowest cost possible, so we hit ebay in search of a bargain. A very cheap Black and Decker Toast-R-Oven was on offer. The description was “only used a few times”, and the grainy photos showed an indeterminate “foreign” plug with an adaptor. Now, we aren’t generally in the habit of assuming that “some bloke on ebay” must know what he’s doing with electricals, but with the auction starting at £5 (and not going up a huge amount from there by the end) it seemed like a good idea.
