gosh... so many boxes... you must have a very large crew.

Went to CT hardware's roadshow.
Seems like Dewalt really want to fight for Malaysia market.
Their hammer drill and Random orbital sander promotion is good.

Too bad I have many bosch batery already can't jump ship.

This time didn't get anything big, only the makita product catalogue.

Saw this circular saw cutting guide in taobao.
Seems like easier to use than 4 feet long aluminium guide.
About rm200 excluding transport to malaysia.

Similar thing in amazon costs USD100 excluding transport to malaysia

New toys.
Kreg automaxx clamp.

I have been looking for a master/slave trigger switch ever since I finish building my dust collector. Those available in amazon works at 110v and freaking expensive.
Don't even know where to find it in Malaysia, then I found this circuit board that has the master/slave function in taobao. Bought it and build my own master/slave switch, it works.

Its to use with my dust collector.

Master = Table saw/ band saw/ things that make dust
Slave = dust collector / vacuum

When I turn on the master, salve will turn on too.
When I power off the master, slave will turn off about 10 seconds later.

Very useful as I dont need to walk to the dust collector turn it on, walk back to table saw, walk to dust collector to turn it off...
Gets tired when I need to make many cuts, also reduce noise especially the vacuum.

I need to let the dust collector runs for extra 10-30 seconds after machine turn off to clear the residue dusts.
Anyway a jig to turn off the DC after some delay sounds more cool.

Useful for occasional work fixing household things.
Direct order from Amazon is cheaper.

Nope, the power for the chip and relay is already supplied by the circuit build into the board.

The lighting control switch is not suitable, some machines are more than 1500w so it will blow the switch.

The AC delay timer thing is more suitable I think but I wonder how the timer starts counting? Not really familiar with electronics.
The master machine can operate from short 5 minutes (table saw) or 30 minutes++ (sander/bandsaw), if the AC delay timer can start countdown after the master machine is power off then it will be a good alternative. Looks more robust too.

Btw thanks for pointing out that grey color thing is the power supply. I keep thinking that is a capacitor.

Yes. DC starts whenever I power on my table saw or machines that connect to the master socket.

Here is the link to the product. Its in chinese.

All my machinary goes through the timer.
My connection is a bit different, here is my connection
1 - slave live (DC)
2 - live for wall socket & Master (table saw & machines)
3 - neutral for master & slave
4 - neutral for wall socket

The connection in the chinese diagram should be
1 - slave live (DC)
2 - live from wall socket & Master (table saw etc)
3 - neutral for slave(DC) & wall socket
4 - neutral for master (table saw etc)

I uploaded a diagram I draw.
1) The main wall socket controls the power to everything, so make sure total power draw can handle by the socket.
2) The slave mode toggle controls whether the slave socket will be triggered by master or always on. Lets say I want to use the duct collector to suck wood chip on workbench then i just toggle the switch to turn on the DC.
3) master socket goes to the machines, the machines has individual on/off switch on them to start. So the master socket is always on power.
4) the slave socket behavior you can refer to item 2.

I use the sockets with power switch coz hardware store only sells that. The on/off switch on the socket also acts as another layer of protection just in case, I hope.

I draw another diagram to represent the difference in the design.
1) The main switch does not turn on the dust collector when the main switch is turned on.
2) The dust collector (slave circuit) is turn on when current sensor on the master circuit sense a current draw. The current sensor also set the time to stop the dc when no current draw is detected.
3) The switch inside the table saw is responsible to turn on/off the slave circuit by increase/stop current draw on master circuit.
4) When the main switch if off all power to DC & table saw is cut off immediately.

With this design I don't need to walk to the main switch to turn off the dust collector, just turn off the machine and the DC will turn off later.

That current detect in aliexpress would work but it will require additional companents.
I will stick to the current one I have as I not good in electronics.
Durability... well, see how down the road lor.

Takes 6 years to reach requirement to start V2.

Guys I will create a new thread.

Admin please close this one.
