Oshpark Projects

Thanks Tom.
I never made a thread for the Ferrero Rocher DD driver. :ghost: I actually never even built one myself. Comfychair was looking for a Roche F6 DD driver & before I knew it, I started making one. Made me a little crazy in the end because of constraints I myself imposed upon the design. 0805 parts instead of 0603, two leds & mostly one sided (couldn’t ram it all into totally one sided). Didn’t mention the driver till it was nearly done.

Honestly the indicator leds don’t seem that useful to me. Since the window is/was on the back, you can’t see it while using the light. We already had LVP in firmware plus Toykeeper now made a battery check function for all lights. But the original Roche F6 had a indicator window! Didn’t want my driver to be missing something.

I think Comfy made a thread that has a parts list.
Your SS tail, I’d try a little epoxy just on one side of the SS tail. Let dry then file the epoxy till the tail fits in tightly. Spring does need to go!

If you need more than a few boards and/or your boards are largeish, try gojgo.com They are in China and Ted Chen speaks excellent english. I actually get boards from them faster than from OSHPARK using their DHL 3-day option (8 days from order to arrival). For some 4x6” boards their prices were around 1/10th what OSHPARK would have been. You can send them Eagle .BRD files instead of Gerbers. They also have excellent prices on stainless steel solder paste stencils.

Found a fitting driver, could it be this is not in the OP list?

[WIP] 6v-LED TK35 clone driver thing: for TK35 and ‘friends’

It is slightly smaller then the original driver, but should fit.

Quick (I hope) question:

I am trying to simply shrink my lighted tailcap board down to 17mm from 20mm. I haven’t messed with Eagle in awhile and I feel like I’ve forgot everything. I was able to change the radius of my milling layer, but I need to move the pads in further. For the life of me, I can’t ‘select’ the pads to move them. I can move the vias and everything else without problem, just not those pads. When I created the board, I used a template for an 0805 cap to get the pad spacing right instead of drawing them freehand. Maybe that has something to do with it?

Is your top origin and bottom origin layer active? It displays a thin black “x” or “” at the center of a component. The is what you click to move it.

Also the “x” should be actually oriented as a +. When it is oriented as an x that means the part is locked in position and must be unlocked before it can be moved.

No they were not…

Thanks for making me look dumb :bigsmile:

All is well now

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.

Here is a comparison link.

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
