BreadBooster: dual output breadboard power supply with built in voltmeter

[bbkris]

Hi I’m Kris and I’ve created a device called BreadBooster which is a dual output breadboard power supply with built in voltmeter and short-circuit management system.
Currently, BreadBooster is available through my Indiegogo campaign. Check it out ...

Hi bbkris, I'm interesting to see how successful campaign will be. I wish you luck and two things comes to my mind: how you got TM for BreadBooster and why 12.500 EUR? Sorry if such questions are inappropriate/indiscreet. Just ignore them if that is a case.

Hi Chris,

Do you have any NVRAM in the processor? Then it would make sense to replace the tactile switch with a switch + rotary encoder and store the set values.

Hi prasimix, thank you for your interest about BreadBooster.
TM – is just a sign for unregistraded trade mark so there is noting  special about it. A ™ serves as notice to the public that the words or symbols are an unregistered trademark. However ® sign is something much different. 12500 EUR is minimum amount of funds required for me to organize and start production of the BreadBooster-s.

Hi PAOPBZ, switch + rotary encoder consumes much more space than just a switch. With the current design tactile switch is only practical solution. Remember, BreadBooster voltage levels are set via trim pots, usage of rotary encoder needs some extra electronics to be added – maybe a project for the future

But why? To looks bigger, more serious then you are? Does that makes your product better, or it's just marketing trick to grab more attention?

Looks very optimistic for the first campaign (and product complexity), but let see what will be the "crowd" response to the product (and TM sign).

Hi prasimix, as I said previously a ™ signs serves as notice to the public that the words or symbols are an unregistered trademark - If however a ™ sign contained in a product name gives to your eyes some kind if product grandiosity that certainly was not my intention - be aware of your subjectiveness.

If your product could provide split +/- 15v supplies it'd be popular among the DIY audio dudes...



EDIT:  Your, not "you're".  How embarrassing.

Delta, thank you for the tip

+1 (if ripple and noise is acceptable for that people)

... and another suggestion that possibly could be fixed in this revision is making output reading more stable. If you cannot stabilize output to 10 mV then decrease the frequency of displaying measured value or employ some averaging. That instability of second digit does looks good in your video.

At full load current  ripple voltage is around 100mVpp. I need at least 10-20 BreadBooster samples in order to find a level of ripple voltage with statistical significance. An averaging algorithm will be added to stabilize the last digit. Current BreadBooster is a working proof of concept, however a production device will have a new PCB design with better EMI mitigation.
