Trimino

This is an exciting game made of 56 unique triangle tiles with a number on each corner, similar in concept to a domino (more about the game here https://en.wikipedia.org/wiki/Triominoes).

To ensure durability, as this was a gift to my kids’ elementary school and expected to last many years, I used hard maple for the tiles and gathered all my design and implementation skills, and mainly patience, to generate g-code that will make these 56 one-off’s.

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.

Just another chest of drawers

Made of MDF and French Oak legs, this chest is my first attempt to paint a piece of furniture and I am quite happy with the result (meaning I know how to do it right next time….).

Made for my beloved sister, here it is without further ado.

 

Remote Control for shop Dust Collector

Few years ago, when I made this remote control for my shop dust collector I did not think it was worth publishing. Recently I noticed a forum discussion asking for details so here it is.

No experience in electronics, just basic understanding of electricity and current flow, and some basic tools are needed in order to build this unit, which essentially is a collection of off-the-shelf building blocks we integrate into a working system.

Installed remote control for dust collector

We start with a remote and a receiver used for garage door opening and similar applications. Usually they come as a set but you can also buy them separately and teach the receiver to recognize a specific remote. The other two parts in the box are a power supply needed to provide current to the receiver. You can use an open frame power supply mounted inside the box as I did or a wall-socket power supply that will keep the box smaller and less packed. If you have electronics junk laying around, most probably you can find a power supply you can use from an old printer and many other devices, just make sure it provide the same voltage needed by the receiver. The relay, which switches the dust collector on and off, is also not a specific component and can have many implementations. In my case I used a Solid State Relay (SSR), which acts like a mechanical relay but has no moving parts. It is more reliable but for this application, any relay that can hold the power needed by the dust collector will do. Make sure to check the power (Volts X Amps) your DC drawn and match the relay to support it as minimum.

Finally, you need to wire the power supply to the receiver, pair between the receiver and the remote control (usually done by removing the “teach” jumper from the receiver’s PCB, clicking on the remote button and replacing the jumper), and wire the relay from the main supply to the dust collector using standard plug and socket.
