/challenges-projects/project14/makingtime/b/blog/posts/bulbdial---a-tale-of-a-sundial-without-the-sunWhen the Making Time competition started, my long-term memory forced my thoughts back into 2011 (sounds like a virtual time machine) when I was prototyping a sundial based on a regular clock movement and some LEDs, called a bulb dial.

Good for walking about in the dark and you want to know the time. Maybe not so good for sunny days, but then hey! who needs to know the time on a sunny day.</p><p>&nbsp;</p><p>Dubbie</p><img src="https://community.element14.com/aggbug?PostID=10691&AppID=277&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/challenges-projects/project14/makingtime/b/blog/posts/bulbdial---a-tale-of-a-sundial-without-the-sunSun, 10 Jan 2021 19:17:54 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:cfdb4a59-179e-4257-9742-43c22390590eDAB0<p>Very cool implementation.</p><p>&nbsp;</p><p>DAB</p><img src="https://community.element14.com/aggbug?PostID=10691&AppID=277&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/challenges-projects/project14/makingtime/b/blog/posts/bulbdial---a-tale-of-a-sundial-without-the-sunSun, 10 Jan 2021 11:21:34 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:cfdb4a59-179e-4257-9742-43c22390590e14rhb1<p>I like your project a lot, especially your homemade slip-ring.</p><p>&nbsp;</p><p>One suggestion even for this pre-PCB would be to overlap the tape in the same direction, akin to roof tiles: assuming the motor only turns one way the wiper contacts would always drag from high tape (double thickness joint) to low (next section of single tape) and will create less loading to the motor....then again you mention wireless energy transfer is you goal so perhaps not necessary <span>[View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-cfdb4a59-179e-4257-9742-43c22390590e/contentimage_5F00_1.png:16:16]</span></p><img src="https://community.element14.com/aggbug?PostID=10691&AppID=277&AppType=Weblog&ContentType=0" width="1" height="1">
