Also thanks for offering additional discounts for this group-buy, we'll see if we can get more participants on-board!.

You can usually tell when people are above board by how fast they ship. Let me ask around town. I know a few electronuts that might have a use for this buy. I'll ask around tomorrow and report back. We may put elepro in business before this is all said and done  |

Just got the Mouser parts in for the one test meter, the DIP socket part number I ordered 517-4828-6004-CP won't do. It's the "wide" DIP which is .600 wide. (the PIC16F883 that Elepro specifies is a .300 wide chip) So after downloading the data sheets for those dual wipe sockets, it appears that the 3M dual wipe sockets don't come in 28-pin length for the .300 width skinny DIP. But, the 3M dual wipe sockets are "end stackable" which means we can just order 2 of the 14-pin parts and place them end-to-end, they are designed to allow this. Sure we could use machined-pin sockets, but some of our participants might have trouble inserting the chip as they tend to be a bit tighter and often need a insertion tool.Another thing is the 'kinked" leads on these guys, I'm thinking they might give some of our particpants a difficult time inserting into the PCB, they are available in straight leg option so I'm of the opinion we should specify those in our parts list. (the kinked leads are meant for machine insertion so the part stays in place after the machine lets-go) I would propose to the group that we change our chip-socket part number on our main parts list to two (2) M# 517-4814-3000-CP @ $0.19/ea Also note that the M# 517-974-01-16 (the socket the header plugs into to connect the LCD board to the daughter board) when looking it up on the Mouser webpage where you do parts searches it said "in stock" ...but... when I got to the order confirmation webpage it said they were on back-order and 2-weeks out, so for this one test meter I just ordered 2 of the 8-pin sockets M# 517-974-01-08 and will install them end-to-end, it will do the same job. Otherwise everything else looks like it will work and fit. I guess it's time to go cook up a PCB for this test unit!

This is exactly why one smart guy needs to build up a prototype before making up the kits. In my experience with building up electronics projects, most of the little hangups are mechanical problems; getting the right parts so it all fits together. Take your time, sort out the problems, and make it right. No big hurry from me. |

Being new here, and a little confused as to how to buy in (and the thread length seems to have exceeded some limit on the forum software -- can't tell for sure where the end of the thread is...)... 1. Can I still get in the buy? If yes, please count me in. If not, good luck anyhow and I'll watch for the results. (In the meantime, I'll use my klugy-battery-DVM-with-Hall-effect-device-glued-to-the-end-of-a-stick) 2. I'm happy with whatever group decisions are already made. However, if you need a builder/prototyper at some point, let me know. 3. Even if it's too late for me, thanks, RedHouse for coordinating. --Paul |

Bottom-left is one made from Elepro's PCB artwork, has pin-terminals for the switch leads and shows how we use two 14-pin DIP sockets stacked inline. Bottom-right is one I made up my own PCB artwork for, based on Elepro's and doesn't use the pin-terminals for the switch leads, but wires will be soldered directly to the board. The pads for the capacitors also allow both 5mm and 7mm pad spacing. The top board is the LCD display module (upside down) showing how I had to use two 8-pin sockets instead of the 16 pin one specified in the parts list. (the 16 pin socket was on backorder at Mouser)

I'll take two. Seriously. I was told to get one for the shop, and well, I still want mine. Since it will be a completely separate transaction, please attach the name "AAI" to the second one.

at this moment i have 18 pic.... then, with the one that i shipped are 19.... you are 19 (with 2X Defaced).... you have to decide if it's time to close the group buy.... I also can order them but i would do this only after that Redhouse make the test and give the green light.... then the wait will extend.... bye

(a two part shippment) You could also re-consider the idea I proposed in the beginning where you and I could enter into a licensing agreement and provide the hex file so I could source and burn the PIC's locally and distribute them much faster. (which would make the possibility of future kits much more likely) When the PIC arrives and I get the verification-build assembled and running, how many in the group-buy would like us to call that good and proceed with Last Call ...or... would the group prefer to wait until I can get the verification-build over to Wolfe or Jason to test it up against a commercial unit. Personally I'd be fine with calling it good if the verification build powers up and works as described, then getting calibration comparison information later when more convienient. (for instance, Wolfe or Jason and myself will need to schedule time that mutually works for us and it's summer vacation time so like for myself this weekend is off-the-table because I have other commitments) Everybody chime-in please....

I think it's a good idea to verify it against a commercial unit.

So we're currently at 18 orders (19 PICs) at the 15+ price break of 20-€ ($27.87-USD) this group-buy is prepared to throw you right around 374.00-€ ($530.00-USD). If you have to split-ship because you are out of PIC's it seems like the extra 5-€ ($7 USD) for shipping shouldn't be a show stopper should it?

Verification of the prototype against a commercial unit before the deal goes through sound like a good idea to me.
