Let us know when you get some more in, I have a customer that asked about it a few days ago and might be needing one or two.

Noted. Will do. Given the interest again, the priority just went up.

Sean,
I have one if you need it I can send it to you and you can replace it later.

Thank you for the response, sorry I took so long in replying to it. I definitely want one so please keep us updated as to availability. If it works as well as I expect it to I can see myself wanting a few more in the future. *grins*

Status update: I got the new (slightly updated, now at rev. 1B) PCBs in a couple of weeks ago. I finally got around to building one a few days ago (needed to make sure this PCB revision didn't have any flaws), and it worked just fine, so I'll be starting another batch here within the next few days. Should have more to sell within a week.

Didn't want y'all to think that I forgot about this.

Ed, put an assembled kit aside for me. I missed out on the last order....

Thanks!

Aloha Ed!

Coincidentally accelerating my whole-car LED upgrade, so...

Please put me down for (1) AILD-1 Main Unit (Assembled) & (1) AILD-1 connection kit for '78-'89 Porsche 928.

Mahalo & sending identical PM!

I too have done the LED change over, and Sean says I need one of these...so...I'll need one as well. Let me know.

Any updates on availability? Just found this and I'd like to use one for an Audi project I'm working on currently.

Hi Ed, very satisfied w/the 2 units I have.

Please put me down for an additional two assembled units.
When can we start ordering them from your Website please?

Thank you,

Dave K

Ed - I would be interested in one too.

Question - how easy would it be to modify your design to control interior lighting LED's as a soft fade out and relatively quick fade up module. Concept would be to have the device fed by the existing delay relay - for the main delay function then trigger the LED fade functions Quick on and slow fade off.

Approx specs: <0.5 sec fade-up (variable?), Variable (pot) Fade-down in range ~1 sec - ~5 sec.

Challenges are your existing module is a supply side device while we need a ground side device for the interior lights - however generally this is even easier (just different). And you do need a variable ~linear fade option Vs. an adjustable level - But still a very similar circuit. Depending on config this likely needs a very low quiescent current if it's always supplied or a self-powered mode (for the fade time) if it's supplied by the interior light switching circuit...

Thoughts?

I developed a purely linear circuit years ago to do exactly this for the stock incandescents - but of course it's no good for LED's.

Yes... I'm happy to report that I just finished up a batch of ten units last night. I'll be reviewing my various e-mails, Rennlist PMs, Rennlist posts in this thread, etc., and contacting people who were on the "informal waiting list" in the order of those requests, and then providing instructions on how to order. Expect to hear more Thursday evening when I get some more time to sort that out.

I expect to start another batch right away, then, as I suspect the current batch won't last long.

My apologies for how long this has taken; I've been dealing with some family problems over the last year that have consumed an unbelievable amount of time and energy. Perhaps I'll share that story over in Rennlist OT sometime.

Sounds quite doable. And would probably be an enjoyable challenge. But... it's unlikely that I'd be able to work on it for quite a while, given how little time I have had lately and am likely to have in the near future.

Great project, let me know when you have built some more please?

I faced similar challenges when designing a replacement for the acceleration sensor under the seat on PSD equipped cars, not taking all the credit though as JDS is my partner for them. Far lower demand though so still all hand made.
Love the desktop milling machine, does it also cut aluminium?
