Negus toolboxes project

In the past few weeks I was working on a family project of restoring my father’s hand tools and building wooden toolbox to contain the tools along with historical details and personal message to future generations. The toolboxes made from wood salvaged from my parents bed have been given to family members last night during the Rosh-Hashanah dinner at our house.

Being a personal project with an attempt to touch both past and future, it is hard to describe the emotional importance of the project to all of us, so I will leave it as is but will happily share some photos with you.

Active fume Exhaust for 3D printers (MB R2X implementation)

Reading about ABS fumes made me worried as I share the same space with my Makerbot Replocator 2X so I designed and build this active exhaust with a fan I removed from some scraped equipment.



What you’ll see is the first version which is working perfectly but lacks the fineness and style which I will (maybe) do at a later stage. Nevertheless, it works fine, no smell in the office and no worries, no extra noise and no negative effect on the printer due to reduced temperature or airflow.

A 4x4x4” Cubic with 5 touch screens, sound, BT/Wi-Fi, run Apps, play sound and video, communicate and connect.


The Problem

Smartphones are great but are not desktop natives. At your desk, your PC or smartphone are never at the right size and position to share content and view multiple sources simultaneously. Using your smartphone to show apps, videos or images to someone sitting in front of you is never comfortable. Tilting your computer screen cause you to bend over and stretch across your desk. When several gusts are sitting around your meeting room you lose control once you give away your smartphone to be circulated. When using your smartphone at your desk you have to hold it in order to view the screen, lay it on the table to do something else and hold it again to see if the stock you are following has changed or to view the clock again to make sure you are not late for your next meeting.
