+technetium Posted August 27, 2011 Share Posted August 27, 2011 I'm creating my own personal geocoin, in cooperation with Chuck Turner from Palehorse Design. I've made it a functional geocoin. The front is a slide rule, but on a disk. It can be used to multiply divide etc. Put the one of one circle to 2.5 on the other. The three will align with 7.5 (2.5 x 3 = 7.5) and the 5 with 1.25 what also can be regarded as 12.5 because on a circle the numbers will continue. That's the reason the circle contains a fractal, Sierpiński's triangle, also an infinite repetition. The largest empty triangle contains the electron configuration scheme of technetium. In the other triangles rays are visible: No stable version of technetium exists. The slide rule also has a trigonometric scale (for the calculation of sine, cosine etc.) The back of the coins shows a Smith diagram. This was used by electrical and electronics engineers to determine impedance and related things. The coin has a diameter of 50 mm (2") and a thickness of 5mm (1/5"). Inside is a smaller rotating disc. The tracing code is placed on the edge. The coins are tractable on geocaching.com and will have it's own icon. This coin will be produced in four versions: Morning in gold; Evening in bronze; Night in silver; Special in gold and silver (only available in a set of four).

+Crowesfeat30 Posted August 27, 2011 Share Posted August 27, 2011 Wow! A geocoin who's function goes way over my head (not that that is super difficult...)! Beauty & functionality. You are to be congratulated! CF30 Quote Link to comment
+usyoopers Posted August 27, 2011 Share Posted August 27, 2011 Very cool coin but I feel like I would need to go back to some kind of math class to learn how to use it! Quote Link to comment

+jsarche Posted August 29, 2011 Share Posted August 29, 2011 Beautiful coin! I'd love to buy one when you're at that stage. Quote Link to comment
+ChadsClan Posted August 29, 2011 Share Posted August 29, 2011 I think this is a very cool coin! I definitely want to get some of these. The only thing I'd "object" to (ok maybe "clarify" is a better word) is this part: The back of the coins shows a Smith "diagram." This "was" used by electrical and electronics engineers to determine impedance and related things. The Smith "Chart" (as it's more commonly called) "is" used by electrical engineers. As an Antenna and RF Engineer I personally use it on a daily basis, as do most of the folks in my line of work. It's a great tool, and even 70 years after its invention, it's still extremely useful. Anyway, Great Job! Looking forward to seeing these! Quote Link to comment

Thanks, for the complements. And excusses, I had the impression that just as the slide rule is no longer in use due to the electronic calculator, the Smith Chart has been taken over by computer software. Nice to know it's still used. Tc Quote Link to comment
+Doctor A Posted August 30, 2011 Share Posted August 30, 2011 Not sure I could ever figure out how to use this, but just for the colors and design, I do like the night silver one! Quote Link to comment
+Where'sMyMarbles Posted September 1, 2011 Share Posted September 1, 2011 Very, very cool!! I really like the "Evening in bronze" Quote Link to comment
+Vanelle Posted September 2, 2011 Share Posted September 2, 2011 This is a great coin. Functional and lovely. I'd love to trade once you have them in hand, if you are interested. Quote Link to comment

There will be a presale of this coins at Chuck Turner's Palehorse Design http://phdcoins.ca/index.cfm I'll keep you informed. I love these and since I used a slide rule in high school, I really want one. BUT, when you say "pre-sale" do you mean that we pay you before you receive the coins and then wait an unknown period of time before the mint sends you the coins and you ship? I am allergic to pre-sales of that sort (even though you are ahead of others because you have samples...) Quote Link to comment
GregsonVaux Posted January 4, 2012 Share Posted January 4, 2012 They look fantastic! I'm an engineer, so I am most likely going to buy a set. Please include instructions for how to use them. Quote Link to comment

+technetium Posted January 16, 2012 Author Share Posted January 16, 2012 As you can see on the pre-sale page of Palehorse Design: http://phdcoins.ca/presalefront.cfm The pre-sale of my coin starts at 20 January. The coins will cost $ 14,95 Cnd. I'm very exited about these coins and I hope you like them as much as I do. Tc Quote Link to comment

I am allergic to pre-sales of that sort (even though you are ahead of others because you have samples...) I understand that many people are leery of the pre-sale format. All I can offer in defense is that I have run 17 pre-sales over the past two years with no complaints and no extended delays in delivery. The status of any 'In Production' coin is listed on the front page of the website with an expected due date. This is updated if delays happen, with an explanation of the cause and the new expected delivery date. Quote Link to comment
+Crowesfeat30 Posted January 17, 2012 Share Posted January 17, 2012 Well heck & darn!! The only one I want is the "Special" gold & silver one. But I do not want to buy three other coins I don't want in order to get in. So I guess I'm out of luck. Darn. CF30 Quote Link to comment

+Getzie family Posted January 20, 2012 Share Posted January 20, 2012 Hoi Chuck. Weet jij of de kosten van het versturen van deze 4 coins vanuit Canada naar holland anders liggen dan het versturen naar de Czech Republic.? Quote Link to comment
+ECplus3 Posted January 20, 2012 Share Posted January 20, 2012 Hoi Chuck. Weet jij of de kosten van het versturen van deze 4 coins vanuit Canada naar holland anders liggen dan het versturen naar de Czech Republic.? The cost is the same for me to ship anywhere in Europe. The set of 4 coins would cost $9.54 to ship by air or $7.48 to ship by surface. Quote Link to comment

I'll have to wait a couple more days before I can actually see them since I am still on the road. All orders will be in the mail on the 2nd of April. Quote Link to comment
