No v-scoring unfortunately.... 

These boards have the holes a bit too close to the score-line.  They also have too many holes there, so it is a bit hard to cut & break them apart.

So, is it an copper-trace that separates the boards?

No, it's actually nothing - or at least as little as possible :-)  It's just a slight indentation / groove caused by removing the soldermask there so the pcb is bare. Like this....

Gray = PCB      Orange=Copper    White=Silkscreen    Green=Soldermask

oh, so you only controlled where to put the soldermask, pardon my stupid questions :)

SockiSop looks good. Did you put the number (order number?) on yourself or did they do that?  With mine they've always done it by making the text a negative in the solder mask, so it's hardly noticeable. That's a lot of LCD displays! Do you have a use in mind, or just getting some cheap stock up?

Negative soldermask text?  That would be really nice, but I've never seen that from Seeed on any of my like 25-30 different board designs they've made for me.

The first few boards I actually put the Dxxxx-order number on myself as according to their instructions, but they always ignored it and put their own stuff elsewhere on the board so I stopped doing that.

The LCD's are not for any particular project, except for doing a breakout as we discussed in the Cheap Nokia LCD thread. And as usual I go for a decent sized lot of whatever I buy if the total price is not too high.  This lot were like $1.85 each inclusive shipping compared to the $3.50-$4.50 if I just would have gotten a single lcd from another seller.

Some random cheap crap from eBay.  A few weeks ago bid on, and won, a lot of low cost free shipping auctions.  I set a max bid of either $0.99 or $1.26 depending on the item on about 300 auctions over the course of a few days and in about 25 of them I was the winner.

This was waiting for me when I got back home from my trip. I expect some more crap to turn up in the next week or two. Not all items here was less than $1.26, for instance the DDS modules I got at the regular buy-it-now price of $4.50 each with free shipping.

Two sets of "Alligator Crocodile Test Clips Cable Clamp Wire Lead"
Thermal Grease Paste Compound for Heat Sink
Two sets of "10 pcs AMS1117-3.3 LM1117 3.3V 1A SOT-223 Voltage Regulator"
50pcs 1206 0.47Ohm 1/4W 5% SMD Resistors
Three sets of "10 pcs 5x7cm DIY Prototype Paper PCB Universal Board"
Two sets of "10 pcs 3144E OH3144E A3144 A3144E 3 Pins Magnetic detector"
Foldable Mini Jeweller 60X Lighted Pocket Microscope Magnifier Loupe
Two boxes of 3 pcs of Dental  Diamond drills
One set of 50 pcs Red and 50 pcs black crocodile test clips
DDS Signal Generator Module AD9850 0-40Mhz Sine+Square Wave
AD9850 DDS Signal Generator Module
10 pcs LPD6803S LPD6903 SOIC16
1 pcs PL-2303HX HLF SSOP28 USB to Serial Bridge
1 pcs Digital Humidity & Temperature Sensor DHT11
2 pcs T10 5x5050 SMD LED Green Super Bright Bulb
2 pcs T10 5x5050 SMD LED Pink/Purple Bright Bulb
2 pcs short colored USB to Micro USB cables
2 pcs of 4-port USB hubs
500 pcs 3x1mm Disc Neodymium Magnets

Those hubs look suspiciously like the ones I bought to dismantle for inside a TL-WR703n - if they are, then I found that they have no visible xtal, and stop working after 6+ hours (which is bad when your root drive is on usb...) - I suspect due to timing drift.

Still, I like the idea of throwaway bidding on random junk... :)

the filtering that comes on the ad9850 boards SUCK, i got one and had to change caps and inductors, also layout sucks on smaller one

A thousand USB mini-B connectors. In my defence I needed some and they were cheap (which probably means they'll break immediately), but still. 1000 of them. orz

Amazing! And the trickle of random stuff will be a treat for weeks to come!

Wow -- how were those packaged and shipped.  I wonder if they stick the machines an mess everything up?

Heh, I got 100 of those magnets last year, They work great, but are so small they latch onto your tools without noticing and stick to everything else. I think the envelop they came in was stuck to my mailbox pretty good.

A couple months ago I picked up a roll of the RGB LED strip with the little control box and remote from eBay. The LED strip looks nice, but the remote basically sucks. It really wants to stay in the fast flashing crazy mode and will only stay on a few colors. I'm making my own controller anyways as part of an aquarium project. I wondering if they are all like that or I just got a dud.

Yes those controllers do suck. Today my RGB controllers featured on this week video.[s:]I'll post the files shortly in the Projectlog section.[/s:] viewtopic.php?f=56&t=5165

THe rgb ledstring was good quality though.

Well these actually got a 12MHzc rystal mounted at the bottom of the single sided pcb. It's really incredible to see a 4 port hub with so few parts. I've got a some 4-port hubs that are a few years old and they have 4 or 5 ic's and more like 50 discretes in them.

They're really really tiny, so 500 of them is about the same size as 1.5 sugar cubes. So they were just wrapped in some bubble wrapper and then put in a regular envelope.  But at close range they are really strong. I put all of them in a line and hold on to the top one it can carry the weight of the remaining 499. One of them can easily hold a A4/Letter sized paper on the fridge.

Yea, I'm not surprised.  I got these boards to use for parts for building my own board and it was cheaper to get these from ebay than purchasing the 125 MHz oscillator and the AD9850 at my local Element14/Farnell. :-)
