Quote " Adding a variable boost board and a tiny LCD display to a device like the ego could add less than $5 to the manufacturing costs if done in high volume." Quote
The problem is that there is not enough demand to justify those startup costs , Ya a small LCD display like on a MP3 player is cheap @ 100,000 units , for 500 units it is NOT cheap , finding an OFF the Shelf LCD display is not easy .
I understand what you are saying but in qty's of 500-1000 units all this stuff adds up ( not to mention the engineering time and $$ )
A PWM design is easy and cheap to make , they will be here very soon IMO ( Just ask Cisco ! )
We are working on a design that requires custom molded enclosures , this takes a lot of time ( it has to be right the first time ) and a lot of $$ to design and bring to market . I dont know if you have ever done anything like this before but it is a difficult task and takes time and $
To design to a market that can absorb maybe 2,500 units it is a totally different process than to do 100,000 units.
Just saying , you have good points BUT need to be aware of the issues the MFG's face for small volume manufacturing. and YES these are small volume devices.
