This resulted in occasional tiny shorts between coil turns and a reject rate that made it impossible to continue using this method.<\/p>\n<p>Don&#8217;t worry though, I haven&#8217;t returned to hand wound coils and they remain as easy to build as the V1.5 boards. Another change is all the parts are now through hole &#8211; no SMDs on either the baseboard or the pieces. Externally the board is identical to the V1.5, using a mixture of IN-15A and IN-15B nixies.<\/p>\n<p>They&#8217;ll be up for sale shortly and kits will be ready to send out within the next 1-2 weeks.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>After yet another redesign the third and final batch of chessboards is almost complete.
