I banged it up so it&#8217;d fit on my wrist and here is how that looks. I can use that to try to look cool and for typing (that is noteworthy as that is <a href=\"https:\/\/www.swisswuff.ch\/tech\/?p=46\" target=\"_blank\" rel=\"noopener noreferrer\">just about what other people use ridiculously expensive prostheses such as the iLimb<\/a> for).<\/p>\n<p>By no way is this meant as a way to put down iLimb users but for a total cost of 78&#8217;000 CHF out of my own pocket (<a href=\"https:\/\/www.google.ch\/search?q=78000+chf+in+usd\" target=\"_blank\" rel=\"noopener noreferrer\">see how much is that in dollars!<\/a>) I rightfully expect the combined performance of a luxury car with all the electronics, <em>and <\/em>a high end power tool, <em>and <\/em>a high end computer workstation &#8211; all in one. And for the iLimb I see more like a total cost of five small electric motors, a number of cast plastic pieces and some screws. And if they sold them for 5&#8217;000 CHF I&#8217;d have gotten one on my own right now.<\/p>\n<p>These wooden hands here, however, sell for 25 CHF (some 1\/3120th of the iLimb cost) and so may I introduce the term <em>adequacy<\/em>. I can and plan to use these as experimental substrates. There is no expected performance. I may wreck some material during tinkering and trying.<\/p>\n<p><!--more--><\/p>\n<p><strong>Mounting it<\/strong><\/p>\n<p>(pics&#8230; ummm&#8230; will follow)<\/p>\n<p><strong>First look<\/strong><\/p>\n<p><img decoding=\"async\" class=\"alignnone\" style=\"margin-right:450px;\" src=\"https:\/\/www.swisswuff.ch\/images\/wood1.jpg\" alt=\"Wooden Hand\" \/><\/p>\n<p>I can type with it by extending one finger down:<\/p>\n<p><img decoding=\"async\" class=\"alignnone\" style=\"margin-right:450px;\" src=\"https:\/\/www.swisswuff.ch\/images\/wood2.jpg\" alt=\"Wooden Hand\" \/><\/p>\n<p><img decoding=\"async\" class=\"alignnone\" style=\"margin-right:450px;\" src=\"https:\/\/www.swisswuff.ch\/images\/wood3.jpg\" alt=\"Wooden Hand\" \/><\/p>\n<p>Problem is that the finger positions are not sturdy.

These break really easily and make for bad substitute for a prosthetic hands. I don&#8217;t need full movement or even any movement &#8211; but I will carry or push items and generate significant forces. I broke that hand and even though it can be fixed, reinforced, improved, mechanical resistance is a huge factor in these hands.<\/li>\n<li>Screws on joints are too weak. Fingers almost move by themselves and that causes more of an obstacle than a supportive help. Off the shelf hands contain regular wood screws. In order to render the joints more stable, squeezing the joint using a two part (male, female) screw is possible (I mounted a couple on my wooden hand) but ultimately to complicated to handle.<\/li>\n<\/ul>\n\n<div class=\"twitter-share\"><a href=\"https:\/\/twitter.com\/intent\/tweet?via=swisswuff\" class=\"twitter-share-button\" data-size=\"large\">Tweet<\/a><\/div>\n","protected":false},"excerpt":{"rendered":"<p>This is part of my Red Hand Series.
