This is so great Tracy!
Wow everyone really came together on this!
Seems like you combined your 2 projects together onto the Braille calculator?
Would love if you could update us on the instructions etc on that @LFv1 is going to add this to the library!November 12, 2020 at 10:05 pm #10578
@ZKv, thanks. I added some instructions in the previous Google doc: https://docs.google.com/document/d/18mJAlz1Jhtu5b_Kb4hG6tOKM00rnQ4d1fztWh-7v8zs/edit?usp=sharing, @mmc_li let me know if any questions. Thanks.November 12, 2020 at 10:05 pm #10579
@zhangcu2 @brentcourson @gravescolleen Hi Folks! Wanted to touch base on this project to see if y’all had any insight to some questions I have.
I am one of the Engineering students working with MMC. I am working on some documentation for [this project](https://makeymakey.com/blogs/how-to-instructions/makey-makey-braille-calculator-by-tracy-zhang) (assembly guide, user guide, etc) but am having some trouble sourcing the braille stickers used in this project. https://www.aph.org/product/feel-n-peel-stickers-ueb-braille-print-numbers-0-100/# . They only ship to the USA and also only will contain the numbers and not the other buttons that are needed on the calculator. I am trying to find either a DIY solution for braille or sticker options that makers would be able to source easily to create this device if it was requested on the website. If you have any ideas on this I would love to hear them. I am in additon reaching out to some braille users to get thier feedback but if you have any contacts of potential users it would be great to get their feedback aswell!November 12, 2020 at 10:05 pm #10580
Hi Tyler, I am reaching out to the resource center for persons with disabilities in our university, hopefully, they will have information on those questions. Thanks.November 12, 2020 at 10:05 pm #10581
@MMC_Tyler, a response from my MSU colleague: We use our Dymo tape Braille label maker for labels with Braille. https://www.allegromedical.com/daily-living-aids-c519/reizen-rl-350-braille-labeler-p213649.html?sourcecode=allegro&utm_source
And also I found one selling in Canada: https://www.braillebookstore.com/Contact-UsNovember 12, 2020 at 10:05 pm #10582
@zhangcu2 Thanks for those resources! Those label makers are definitely a consideration for how to produce the braille. The only concern would cost of those but they have the huge benefit of being way more simple and consistent than other methods.
I called some folks from APH and found out about these [slate and stylus](https://www.amazon.ca/Lines-Cells-Braille-Writing-Slate/dp/B017UJXL1S/ref=sr_1_1?dchild=1&keywords=braille+writing&qid=1622740561&sr=8-1) method for writing braille by hand on braille paper. There might be an opportunity here to create a 3d printed version of the slate to lower cost of making the braille calculator and just as a stand-alone device. From what I heard from the individuals at APH was that the slate and stylus are hard to come by. But not sure if this is because the community doesn’t use it anymore but this could be a potential for DIY braille aswellNovember 12, 2020 at 10:05 pm #10583
Hi @Tyler_Fentie, our team discussed that the best option for making a braille calculator in the future. We would purchase a standard computer number pad and apply braille overlay stickers for keyboards.
Let me know if you need any information about our build for @zhangcu2.November 12, 2020 at 10:05 pm #10584
Hi @brentcourson! Thanks for sharing that. I just wanted to confirm you mean a braille overlay like [this?](https://www.amazon.ca/Braille-Keyboard-Stickers-Visually-Impaired/dp/B001BPYJQO/ref=pd_lpo_504_t_0/144-8842045-1702334?_encoding=UTF8&pd_rd_i=B001BPYJQO&pd_rd_r=ce369a10-397d-4504-bef6-129b351d96c3&pd_rd_w=C3kb9&pd_rd_wg=VM71E&pf_rd_p=55ea5ed7-d8ce-4183-b0cf-37e635680f3e&pf_rd_r=3GWFG8K52EHYKX0DT92F&psc=1&refRID=3GWFG8K52EHYKX0DT92F) Looks like the ones I can source are quite expensive unfortunately but could be a good option for other devices in the future.November 12, 2020 at 10:05 pm #10585
Hi @MMC_Tyler, yes I found them for about $20 in the US. I also came across a few vendors that make custom embossed plastic stickers. We also discussed 3D printing replacement key covers using a resin printer. Another option would be to laser or drill into the keys and insert plastic or metal spheres.
Our thought about going with a commercial keypad is that many people learn to type without looking at the keys. If the keys are in a standard position it would be easier to develop this skill.November 12, 2020 at 10:05 pm #10586
@brentcourson yeah that makes sense for sure. I was recently pointed towards this [post](https://forum.makersmakingchange.com/t/virtual-maps-for-the-blind-and-visually-impaired/1237/9) regarding some 3D printed braille options. I think this could be the best route from a “makability” perspective for the average maker
