Dekatron DoHickie Kit - Includes all parts & printed circuit board, less dekatron tube.

In kit form, get yourself a dekatron do-hickie. What's a do-hickie ? Its the next step beyond a spinner. Instead of watching the dekatron's glow simply spin in circle, this circuit takes advantage of "computer" technology, to generate some more interesting patterns. By the push of the button, you can select between 4 different patterns. One of them responds to ambient sound, that is picked up by a microphone. The audio level is used to mimic and old magic eye tube. The microcontroller, also has the advantage, over the spinner, in that it can control the the glow position at any of the 30 cathodes (or 40 cathodes, of the 3-guide tubes) positions, either guide or main, as opposed to the 10 main cathodes, that the spinner, is limited to. The micontroller, provided with the kit, comes pre-programmed. Its also powered from low voltage. 12VDC or 9VAC are the preferred input voltages. Up to 18VDC acceptable. The circuit only draws ~100mA at 12V. A 5.5mm OD x 2.5mm ID power jack is provided, so wallcubes, with current capacities as low as 200mA (higher better) can be used to power it. You're not 'slaved' to the AC line, so power it from your car lighter jack !

Also, because it has an on board switching supply, its much safer, than many of the 'direct' AC powered circuits seen on the Web. It still generates 480V, so it will still bite you, if you're not careful. Still, much safer than other circuits. Switching power FET is controlled, and regulated directly by the microcontroller.

Octal socket compatible with various 8-pin dekatrons, such as the OG-3, OG-4, OG-7, OG-9, DK23, 6802, GC10B & GC10/4B. Not usable with OG-8, since that one has only one guide, and can only spin clockwise. All the others mentioned, have either 2 or 3 guides, and are bi-directional, which is required for proper function.

Here is a video, of the dohickie in operation:DoHickie Video.

Here's a link to all the instructions you need to build this kit, once you receive it:  DoHickie Kit.

The microcontroller that comes, with this kit, has been pre-programmed. If there is any confusion, or conflicting data, PLEASE contact me.

Dekatrons are to be acquired separately, by the buyer. There are many sources available, both on eBay, and elsewhere online. This board is NOT prewired for any dekatron. The builder must jumper J3 to J4 according to the octal base dekatron you intend to use. This is all shown in the instructions at the given link.  

Dekatrons are remarkable tubes. They were used from 1950 to late 1960's. They are the tube equivalent of decade counter ICs, but performed this function in a unique and elegant way. Read more about dekatrons here: Dekatron Stuff. 

Board measures 2.85in x 2.85in (72 x 72mm).

All kits are sorted and stored, in individual anti-static bags. They are shipped that way to the customer. Only a few are listed, but I have parts & boards for many more.

It's a "KIT" !!! That means you get a bare board, and parts. You must solder it together ! That's what KIT means !

Shipping Weight: 5 oz

If postage looks high, place the items in the eBay "Cart", and request an invoice from me. The shipping calculator, is usually not accurate on multiple items.

Items shipped to your eBay registered address (not Paypal's). Contact me using eBay's messaging system. I DO NOT read my email. Its used only as the Paypal payment link.

Domestic shipments automatically have "Delivery Confirmation", which essentially is a tracking method. International shipments will only have their "Customs Declaration" number listed, unless the foreign buyer chooses "Registered Mail". With "Registered Mail", the package can be tracked. "Registered Mail", will incur and additional $12.00 US to the total cost. If you want this option please contact me and wait to be invoiced. If you just pay for it (without being invoiced), the item will be shipped without tracking. eBay only required that I (the seller) prove that I shipped it. A "Customs Declaration" will satisfy that requirement. Its your nickel. From NOW ON, if its lost and you DID NOT pay for registered mail, then THAT'S IT !

There has been a history of delayed packages to some European Union countries. Actually, only Germany. Parcels to Germany will now have a "Packing List Envelope" adhered to the outside, to appease German Customs. If you are in Germany, your package can be held up in Customs for up to 6 weeks !

 

Please pay or contact me about payment within three days after the end of the auction. Paypal preferred. Domestic buyers contact for other payment methods. Paypal ONLY from foreign buyers. If you are sending your payment thru the mail, please email me that you are doing so. I have recently cancelled my mental telepathy services, so I can no longer read your minds.
