All pieces of B7971 x8 now available.

[coggs]

I'm very pleased to announce that all parts for the B7971 x8 display project are now available. There is a B7971 x8 board set in the circuitworks store which consists of the assembled and tested display board along with two 4- tube display boards. In addition, a visual construction guide is will step you through the acquisition of all the necessary parts. Construction should take even the casual builder less than 3 hours.

To the more general reader, it should be emphasized that circuitworks does not supply B7971 tubes. This project is really for the established nixie tube hoarder who already has the tubes.  There were tens, if not hundreds of thousands of these tubes manufactured in the early 70's. They do appear from time to time on ebay.  One note; in a recent ebay auction, a lot of 12 went for over $75 apiece.

Please also keep in mind this is a 100% open-source project; This includes the enclosure which is produced by personal laser-cut factory, Ponoko. They offer other colored materials in addition to black.

Why do I make you go on a treasure hunt for the parts ? So I can concentrate on future design projects. Since the project is open source, I hope and encourage people to work on group buys, offer assembly services to non-DIY types, adapt and extend the firmware to suit your needs or other types of tubes. I encourage you to  use the cogwheel circuitworks google group for these sort of discussions.

Again, thanks everyone for their patience.

So, a kit with all parts is not yet available (all components other than the tubes)?

 

On the case, are we able to build the front plate reversed should we decide to not have the logos facing out?

Yes, you can flip the logo side around. You won’t hurt my feelings J

[Cogwheel Circuitworks]

Regarding complete kits; No. I have no plans to offer that.

[Mich...@aol.com]

So, we have to find all the small components as well?

 

Going to cost us more buy resistors at Radio shack for 4x resistors at $1.   :(

 

I would like a kit, but believe it may not be finished if I have to find all the parts.

 

Do you have a BOM and where to get them?

[Cogwheel Circuitworks]

Please follow all the links in the original announcement to the construction guide and there you will find the BOM.

 

I also mentioned my reasoning behind not offering a complete kit in my announcement below; If others are interested in doing group-buys, I encourage that.

Very exciting! What other enclosure colors are available besides black?

I'm ordering mine as we speak.

[Wayne de Geere III]

Somebody want to put together a mass order for all the components? I know I'd be up for that, I'm going to order either two or four of this clock but I dread sourcing the components, I'm really busy with other more pressing duties though I do love my nixies.

Considered offering completed tube boards as well? I would certainly pay the premium for automated machine soldered produced and tested boards, especially considering the number of units I'm planning to order.

Clear, Blue, Red, Red tint. Quite a few. You just have to make sure to order it in 5.6mm thickness

Right now I have my hands full with other pressing duties also. I’m there is someone reputable out there who might be willing to do assembly. Perhaps you should field it to neonixie-l and tubeclockdb ?

 

The tube boards are quite simple. Takes about 20 but the pins have to be hand stuffed.. Unless we were talking hundreds of boards would it be worthwhile sending it to CN to be done.
