That’s right, we are coming up on the one-year anniversary of the SKBOWE pre-order with 70 units sold and a total of 15,535 car-days (estimated) installed! To celebrate, the remainder of Batch 3 has been discounted to the pre-order price ($99)! Batch 4 later this year will be the last production run, so get yours while you still can.
There are another 17 units of PCB assemblies ready for potting, but without an ETA on when they will be finished, they are being pushed to Batch4.
When these are complete, I am waiting on 8 units worth of capacitors which are backorder until Mid-April, to round out all 100 SKBOWEs. Based on average monthly sales, total remaining inventory should cover until October or November. After that, the future of the SKBOWE project is uncertain…
Batch 3 is on schedule for Feb 15 ship date! Building 40 sets this time, which leaves 10 sets worth of parts left in Batch 4 to experiment with different designs or for custom orders (harnesses, DRLs, etc).
Some fun stats about 40 sets of SKBOWE (80 units):
- 320 wires cut, 640 stripped, 400 soldered
- 400 capacitors + 240 diodes + 80 resistors = 1440 leads soldered
- 80 heatsinks cut and bent, 80 enclosures notched, 80 covers taped
After stuffing the enclosures (heat wire, form wires, tape wires, then test-fit heatsink and insulator), it’s time to mix up some potting compound.
Then each one gets a thin layer of compound, board goes back in, another layer of compound, cover gets glued and goes on, then the whole thing gets wrapped with electrical tape to compress it. Once all of them are done, into the oven for 2 hours at 165F.
I ran out of ABS cement (more on order) so for now there are 11 (so the 9 pre-orders will go out on time).
Stay tuned for more updates!
Batch 2 Sold Out!
Wow! Hard to believe but all 50 of the original Batch 1 / Batch 2 SKBOWEs have sold in just 6 months. They have shipped all over the US, as well as Canada, the UK, Ireland, Germany, and Netherlands. While there were 16 units in the initial pre-order, sales have been stronger than I expected, averaging 6 units/month from August onwards.
Batch 3 / 4 open for Pre Order
It’s sad to see the bin empty, and thinking of the stories that I have heard I can’t let it stay that way – so I have decided to go ahead and order parts for another 50 SKBOWEv2. Again, some the capacitors are backordered so there will be a Batch 3 shipping in February and Batch 4 shipping some time after that. The pre-order is open now if you want to guarantee yourself a set.
The original SKBOWE business plan called for 100 units total, and at this time it looks like Batch 4 will be the last of SKBOWE v2. There are several ideas for features to SKBOWEv3, such as a removable harness and a DRL detector, but the design is still tentative. I guess for now, you’ll just have to wait and see!
I found the connectors that AL use on their bi-xenon projector solenoid control boards (Mouser #571-2-1718346-1 and #571-965906-1-CT) and ordered a few to make pigtails that connect the high beam solenoid into the factory wiring. The OEM connector locks securely into place, and the 12″ (30cm) automotive GXL wire is designed to hold up inside of the headlight housing. Wire is color-coded to match factory wires (yellow = +12, brown = ground) to ensure correct polarity and not look out of place inside of the housing.
AL (OEM) Salvaged Projectors
Most used (salvaged) projectors come with short (cut pigtails) of various colors or no harness at all. I have never seen a set in yellow and brown, the wire colors used in the Volvo headlight housing for the 9005 high-beam connector.
If you want to wire up a projector retrofit without using messy splitters, I am selling these for $20 shipped (Priority Mail) to the US, or $12 with your SKBOWE order (just contact me first!) anywhere. Each order comes with a pair (2x) of 12″ GXL pigtails and four (4x) 4″ black zip-ties to match the OEM internals. You will need to provide insulated butt-style (if you cut-and-splice) or 9005 female (join inside of the high-beam connector) crimps – see this post for details.
Replica Projector Pigtails
Replicas use the same connector but a different pinout: the yellow wire is on the center (pin 2) rather than on the end (pin 1). All new replica projectors come with pigtails, usually white (+12) and black (ground). These will work fine, but if you want to go for a 100% OEM look, you can order a set of these color matched pigtails and swap the pin across. It is pretty easy to swap the pin over using a jewelers screwdriver. Or let me know first and I’d be glad to do it for you.
There are 15 units available to ship from Batch 2 – get them while you can!
I had originally said October (based on the DigiKey backorder estimate) but the caps came early. Haven’t had too many Batch2 orders yet so I thought I’d get a head start on building them…
Got all of them soldered together, and 10 sets potted…
I’ll be traveling for the rest of the month, so I am pushing to finish these tomorrow so orders placed before 9/15 will get in the mail on Monday. If you haven’t ordered yet, yours will ship out before October 15th.
Sorry for the delay since the last update – been really busy getting Batch 1 together – so I’ll consolidate the last of the build updates into one post.
The second order of potting goop came Thursday so I knocked that out.
As it turns out, it’s 10 units to the ZipLoc gallon bag, and two bags to the 0.45 Gallon kit, so it was only 6 pairs, not too bad.
Was a long day… Started with 52 potted units, each needs to be unwrapped, cleaned of flashing (belt sander), and given a good wipe down with isopropyl alcohol.
Then 7 hours here…
After the potting is set, the procedure is:
- Clip temporary zip tie, discard
- Cut wire loop to correct lengths for input/output/ground
- Crimp on ring terminal
- Heat shrink ring terminal
- Cut split loom to length for input + output
- Tape one end of input + output split loom and slide on to respective leads
- Secure split loom at base of enclosure
- Install weather seals on wires (4x)
- Strip wire ends (4x)
- Crimp terminals (4x)
- Install male connector housing and seat weather seals
- Install female connector housing, seat weather seals, and install retaining clip
- Tape up split loom
Anyway, around 1AM
Started packing. Each order gets a whole bunch of stuff that needs to be put together…
By 3PM I had the pre-orders packed and off to the post office. Not sure if they will get processed today or tomorrow, but they are in the mail! Finished the Batch1 orders when I got home and will take them in to the regional hub tomorrow.
Then I took a nap. And then wrote this post. Mic drop.
PS. There are only two lonely SKBOWE kits left that are in need of a good home… Can anyone take them in?
Epoxy Encapsulation (potting) serves to waterproof the SKBOWEs, insulate them from vibration, prevent corrosion, and conduct heat away from the components to the enclosure. It’s the messiest and trickiest part of the build process, as there is no turning back once you’ve mixed a batch of compound – and it’s $260/gallon.
