Not at all!
I’ve done that too!
Instead of locking parts, I often just turn off origins when I’m doing traces and don’t want to accidentally shift a component.
Ok, one more thing. Is there any way I can tell Eagle to just trim off everything outside the milling circle? Or do I manually need to remove all of that? Or will Oshpark be fine if I make the milling circle huge (thick) to cover all of the overflow?
Anything outside the board (milling) will be trimmed by oshpark. It’s best to keep the milling line very thin. Otherwise there can be the question of if you intend them to mill the middle of the line or inside edge. I’ve used 0.001mm, though that’s overkill a bit. With ground rings I always have some outside of the milling and I let it be trimmed by oshpark.

A few more revisions to this great 17mm 7135 driver. Oshpark link.
The latest revision of the Moonlight Special driver. Original design by Mattaus, original firmware by JonnyC, modification and testing by RMM.
V3 Changes:
- Added OTC Capacitor Pad
- Cleaned Up and Deleted Outdated Pads
- Fixed Silkscreen Alignments
- Widened 7135 Pads for Easier Reflow & Chip Stacking
- Even Beefier Traces and More Vias! (More POWER!)
- Improved Edge Clearance
- Pin 3 to Ground Connection Now Does Not Require Bridging to Edge of Driver (Just Solder Over The Circle)
Components:
- MCU: attiny13a-SSU
- C1: 10uF 10V+ 0603 or 0805
- OTC: 1uF 0805
- 7135 Regulators
- R1: 19.1k 0603
- R2: 4.7k 0603
- D1: SOD-323 Schottky Diode
Definitely some tidying up to do. I noticed some of CK’s links no longer work and I know there are boards out that are not listed. As I said in the op I’m reluctant to go mining for this stuff so thanks for posting Rich.
A few updates to this great driver originally designed by Mattaus and others here I'm sure. Oshpark link.
- Added a single 7135 (ML) controlled by a secondary PWM channel (Pin 5)
- Added an LDO option for 2S momentary use (LD2981 / MIC5235 / LT1761 / TS5205)
- Changed voltage divider feed to Batt+ so that LVP with 2S+ cells can work
- Changed “star” designations to MCU pin designations
- Wider 7135 pads for easier soldering
- Slightly changed location and diameter of through-hole vias for easier use

As always. Great looking board.
Is there a different place that offers a service similar to Oshpark (low prices, low minimum order), but can do a thinner pcb? Osh works great for drivers, but for the lighted tailcaps sometimes space is very tight.
Beautiful!!!
Not in the USA that I know of. Places like seeedstudio.com do them overseas in small runs of 10 or more for about $1 a piece, but much less if you buy larger quantities.
Bummer. Have you used that place? are they decently fast?
edit: That price isn’t terrible, and they list a shipping date of 11/16, so it might even be faster than osh. Do you think 0.8mm would be strong enough for a switch pcb?
Seeedstudio is one of the most popular overseas hobbyist PCB services.
0.8mm is pretty thin, but it depends on the switch design and how much backing it has. I'd maybe go 1mm.
I really like gojgo.com I can get boards from them faster than OSHPARK (using their DHL shipping option) and at around 1/10th the cost for larger quantities of larger boards. Also check out dirtypcbs.com
I think we used Smart prototyping to do the .8mm tiny10’s. 10 boards for $9.90. Shipping is extra. Several colors for a tad more. .6mm adds $35
I think .8mm is stiff enough for a 17 mm board.
I’d suggest testing the transistor prototype then do a gb. Tape the boards to an index card and use small photo mailers to keep postage costs under $1 per set. Over seas mailing 1st class letters(which photo mailers qualify as if kept flat) isn’t much more but delivery is suspect to certain places. Other shipping options are more secure overseas but price goes way up. You’ll see what I mean when they quote shipping on that $10 order.
A groupbuy is probably a good idea. I’m hoping to get two versions going, one with a pot and/or a slide switch, and then the version with the transistors. (although pyro and Djozz will probably beat me to it)
THanks for bringing up shipping costs
Texaspyro has much more experience with this so I suggest you check out his leads. GB’s are a pain but a big part of what makes this place special so I’m glad when someone steps up to get it done. Sort of a pay it forward thing.
I have also used gojgo.com and they do have pretty good service and excellent prices if you are doing bulk stuff. I perhaps incorrectly assumed that you were looking for ~10 boards, but if you are doing hundreds it is usually a better deal than seeedstudio or a lot of the others.
Be extra careful to make sure that your solder masks, etc., are correct because there is no preview and if there is something that is a bit off you may be surprised with what you get back. Check and double check your stuff before you send off a large order (I know this from experience).
