Variable Speed Dekatron Spinner Kit - Printed Circuit Board ONLY In kit form, get yourself a dekatron spinner. This spinner uses a neon relaxation oscillator to govern its speed, so you're not dependent on the AC line frequency. Its also powered from low voltage. 12VDC or 9VAC are the preferred input voltages. Up to 16VDC acceptable. The circuit only draws 120mA at 12V. There's a spot for a 5.5mm OD x 2.5mm ID power jack, 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 450V, so it will still bite you, if you're not careful. Still, much safer than other circuits. Switcher based on the LM393 Dual Comparator. It is the same, latest revision, board used on the "complete" kit. Here's a link to all the instructions you need to build this kit, once you receive the bare board:  Spinner Kit. There are many sources available, for dekatrons, both on eBay, and elsewhere online. This board is prewired for the Russian OG-4, neon filled dekatron. It can, however, be rewired for any octal base dekatron. This is all shown in the instructions at the given link. Since, you only got the bare board, I suspect you know where to get all the other components.  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 2.3in x 2.3in (58 x 58mm). All kits are sorted and stored, in individual anti-static bags. They are shipped that way to the customer.  Shipping Weight: 3 oz 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 ! 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. 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.
