Toaster - Dual Output USB Step Up Breadboard Power Supply.

The Story

Toaster came about when I wanted a simple breadboard power supply that could power my standard 3.3V / 5V digital circuits such as a microcontroller, but would also be able to run some analog circuitry at the same time. Since most breadboards these days seem to have dual supply rails, I decided to make something to fit the need and so Toaster was born!

Toaster is simple to use, simply plug it into your breadboard and then into a USB port or charger. Toaster will then provide you with a selectable 3.3V / 5V power supply rail plus another supply rail which is variable from 5V all the way up to 16V. All from a single 5V source!

Output Voltage 1 - Selectable between 3.3 Volts or 5 Volts

Output Voltage 2 - Variable Between 5 Volts and 16 Volts

Standard Dual Rail Breadboard Connection 

Toaster uses a really neat piece of electronics called a DC to DC converter which allows a smaller voltage to be boosted up to a larger voltage. In this case, the 5V input from the USB port can be boosted anywhere up to 16V. Fantastic for powering all sorts of analog circuits! This voltage step up does come at a cost however, the higher the voltage that you want, the more current the Toaster needs to draw from the USB port to achieve that voltage. Check out the table below to see the maximum current for each voltage setting.

USB Cable

Each Toaster will come with a 25cm USB Cable for you to connect to a USB port or USB Charger. The shorter the cable is, the better the efficiency of the Toaster!

Specifications

  • Input Connection - USB Mini B
  • Input Voltage - 5Volts
  • Input Current (max) - 1Amp
  • Output Voltage 1 - Selectable 3.3 Volts or 5 Volts
  • Output Voltage 2 - Variable 5 Volts to 16 Volts
  • Protection - 1.1Amp Resettable Fuse
  • Output Connection - Standard Dual Rail Breadboard 2.54mm (0.1") Spacing.
  • Board Dimensions 50mm x 25mm

What has been completed?

Well, everything about the product is done! I have designed the circuit board, setup a bill of materials and have a working prototype (as seen in the photo's) that has been tested and tweaked. All that's left to do now is get backers so that I can get them massed produced!

Production Schedule

  • 9 March 16 to 30 March 16 - The Kickstarter campaign will be in progress. 
  • 01 April 16 to 15 April 16 - Kickstarter will be processing payments from backers. 
  • 16 April 16 - production will begin. 
  • Mid May - Rewards will be sent out to backers with the expectation of receiving them in June.

Shipping will be through Singapore or China post via the cheapest airmail option. This is to keep costs down as much as possible for backers. I have used this method for all of my successful Kickstarter campaigns and it has been a reliable service. However it can be a slow service depending on your location. I have had people from previous Kickstarter campaigns receive their backer reward in a about a week from shipment and I have others take up to a month from shipment even though they were sent on the same day, by the same shipping method.

Risks and challenges

I have run numerous successful Kickstarter campaigns over the past couple of years and have been able to fulfil the backer rewards with quite a minimum of fuss. The Toaster project is very similar to my previous campaigns and since I will be using the same suppliers and manufacturers, I am very confident that this campaign will run smoothly as well.

However challenges do arise such as delays with components and / or pcb manufacture etc... However since I have been working on projects like this since 2007 and have dealt extensively with component and pcb manufacturing companies, along with running numerous successful Kickstarter campaigns, I am confident that if any challenges do arise, I will certainly be able to overcome them to again make this a successful campaign.
