OPP T-Hook (Compare to historical Trautman Hook)

Invented by J.H. Kosek and Raymond B. Trautman in 1925, the Trautman was popular mainly in the agricultural communities of the Midwest US up to and following the end of its production roughly 20 years ago. We'd like to help bring it back.

Holiday Hope and Hype for Prosthetic Arms

Many of you may have already seen the heartwarming story about the boy who asked for an xBox and an arm for Christmas: Little Boy Asks Santa For Prosthetic Arm So He Can Play Xbox. He was initially embarrassed about the attention to his disability, but "by Friday evening, the campaign had raised more than $53,000, and Christopher’s parents plan on telling him it’s from Santa, the news…See More

One Arm Dove Hunt One Handed World Video

"Great video Jon. Back in the day Bill Baughn and his wife Joyce (bilateral AE) were very active in the hunt and he told some interesting stories. Nice to see some of it for the first time.  Thanks Wayne Renardson "

Hi Jon,

How are you? First of all, great work with the platform and thanks for welcoming me to the community!
I'm guessing you've seen by now but I'm looking at developing upper body prosthesis that enable interaction with others, shaking hands, holding hands, dancing, feeling a childs temperature, feeling someone touch a prosthesis and sharing emotions. It would be super helpful if you are able to spend 2mins answering my survey! 

https://www.surveymonkey.com/s/7HN8FJP

Thanks in advance! If you're interested to know more and have time for correspondence it would be great for my project. It would be great if you could spread it to friends and family who wouldn't mind answering the survey too, through their perspective of how they'd like to interact with a prosthetic hand if it could feel.

Thanks John, we are always happy to share information that will help animals.  We are writing up the official story of the crow and the goose right now to gather all the facts.  We can share the articles once we get them written up.

Sir,
I am a new fan of yours from India. I have read your articles and blogs about amputation. We were a bunch of students who were doing a prosthetic arm project, just for fun. But then we have came across the real trauma of amputation during the pre project survey(read the full story on our blog shabdorg.blogspot.com). After that incidence we taken this project as our life long project. Our mission is atleast we could give our national amputees at least what people of your country can get. In our country each year million of rupee is wasted on research and the final product is kept in the research center itself as a showpiece. The reality is in our country 80%amputees never get more than the bandages over the wound. Anyways we are not in favour the new research of transplantation of arm from a brain dead person to an amputee. Though its almost 100% successful (49/50), it is death of ethics and almost killing someone for a rich man amputation surgery.
In the meanwhile we came across your website and at last we are here. We just want to enquire how really this site helps us to achieve our goal. Please do contact us, my mail id is dasdevashishdas@gmail.com
regards,
Devashish Das,

Some people found it useful that the Carnes arm's feature used position dependent motion combination. There was elbow dependent wrist rotation allowing pronation for an extended elbow and supination for a flexed elbow. So from past experience some position dependency of prosthetic function could be justified to be 'useful'.

With limited input variables, the one and only clever way to exploit these constraints has not been found.

So my guess would be to include the Bosch accelerometer, build a demo and start testing it. Only when you wear it and play with it you can find out how cool or how useless it really is.

Just starting out, Jon, and your link to Open... was very interesting. Just FYI, I have an evaluation board for the Micro line of Microcontrollers. It has a Wii-like accelerometer and some demo software that makes it like a Wii. The accelerometer proper is a digital wonder chip from Bosh, costs ~$5 small quantities. So, if Wii-like motion sensing is wanted, it looks like it is in the bag, more or less, already.

I'm including the simplest schematics ckt. that i ever designed for this prosthesis hand. Please note, i tried to use only those components which are only available in developing countries (like my countriy Bangladesh). Moreover it minimize the cost dramatically with a small sacrifice of performance.

OLÁ JON! RECENTEMENTE ANALISEI ALGUNS ARTIGOS DO SITE IEEE,E
NUM DELES VINHA FALANDO SOBRE SEU CASO.SOU ESTUDANTE DE ENGENHARIA ELÉTRICA E ESTOU INTERESSADA EM DESENVOLVER PESQUISAS NESSE RAMO DE "PRÓTESES".O QUE DIFICULTA É QUE NO BRASIL AINDA NÃO ENCONTREI EM MINHAS PESQUISAS INSTITUIÇÕES VINCULADAS À ESTUDOS TAMBÉM DESSE RAMO.
GOSTARIA DE ENTRAR EM CONTATO COM VOCÊ E SE POSSÍVEL OBTER INFORMAÇÕES QUE IRÃO CONTRIBUIR PARA MEUS ESTUDOS.
