Spectrum Next LED inserts…..Big steps

I’ve been updating the Dev group on facebook more regularly than here

Progress has been slow but constant!, the new Jumper method of getting the LED inserts to connect to the controller works well, if a little fiddly. I think there’s some changes I can make to allow for an easier installation experience.

A big milestone also – The BETA hardware is at such a point now that i’m happy to send it to the core Dev team for actual installation inside a Next….err, except they can’t have the bottoms on as the USB cable doesn’t fit, D’oh!, another re-design needed!

AND – software – My Arduino code’s finally quite stable – Also, from the Next side of things – the i2c code is great – it runs well at 14MHZ, allowing for some interesting sequences on 8 segments…..I’ll start uploading BASIC programs in the next month or two.

Also, a kind of fork in the road….

Throughout this project, I’ve had an end goal of maybe 5-10% of Next owners owning a Blinkenator. at 3000 Nexts, that’d be maybe 150-300 devices sold over a year or two, making my beer money fund quite happy

Things recently changed……and have made me realise that I’ll probably need to step up my game a little…..

The Latest Kickstarter………. https://www.kickstarter.com/projects/spectrumnext/zx-spectrum-next-issue-2

Means that now, there’s over 8000 Nexts in the wild!.

Assuming the same targets, I’d now need to manufacture between 400 and 800 devices…

May not sound much – but at a top level, for just 800 units…….that means some big numbers…..

sourcing 3,200 Plastic inserts….

Sourcing 26,000 LED’s

and with big numbers comes Big Money….and long lead times.

IF someone landed me with an order for 800 Blinkenators tomorrow, at (say) 45 minutes per board, I’d need 600 hours to complete the order.

I have a day job that demands my attention for 160 hours a month. Wife and kids that demand me for a further 80 hours a month…then there’s the whole sleeping and eating thing..

It’d take me a year to be able to fulfil that order 😛

So, the fork in the road……….I may need to do my own Kickstarter!

I’m investigating larger scale manufacture – Full PCBA including through hole, better DFM and Plastic Injection moulding.

All that costs big up front ££…..hence the Kickstarter………is my 5-10% adoption figure massively optimistic. Is it woefully inadequate?

To have any chance at a successful Kickstarter, I need to turn this hobbyist , good quality (7/10, could do better) project into a slicker experience, a better presented finish and professionally produced, not at my dining room table package that would obtain a Crash Smash award, a solid 9.5/10 experience. I KNOW I’m capable of creating the hardware (i’ll learn the software). I’m genuinely uncertain at this time if I would be able to DELIVER that package.

Saying that, I know my limitations, I have a grasp of the fundamentals and i’m costed to the penny for small batches.

Extrapolating that upwards and figuring out where costs stand for different adoption rates is my focus now the BETA 1 boards are ready.

If 30% of Next owners buy this thing, that’s 1800 hours of ‘work’ to do. That’s a FULL TIME JOB!!

scary isn’t it. I have to create budgets that allow for an employee!!
