Yes, still available and happy to send to them but sendle doesn’t work here [emoji848]

Hi Mike,

The controller is of interest to me (even though I have too many projects on the go). I’m amazed at what you’ve achieved with this project. [emoji106]

When I say timing issue, I meant issue of synchronising the reading of data/bits returned from the sensor. It may be noise from the VFD contributes to the problem in some way, but I've had read fails...

I found reducing resolution made readings far more reliable. Try 9 bit and see how that goes (assuming you are using higher). 9 bit returns 0.5 degree steps.

I really love the simplicity and robust nature of this stop. It’s inspiring to see what a little lateral thought and ingenuity has led to overall. Simple and elegant! Thanks

Hi Bob,
I’ve used DS18B20s extensively for a long time, mostly beer brewing machines. I’ve not had trouble with noise but found them far more resilient than analog solutions. Reading-127 is a timing...

The blast gate build is progressing well. Some way to go yet with the control stuff but I’m making good progress there as well. ...

Nice work on these. Although I've tried both sketchup and fusion I ended up designing it 1:1 on paper before transferring that to ply. I think I'm a bit challenged when it comes to things that are...

Hi fletty,
that stuff is music to my ears. I'd not heard of this before so keen to find out more. Can you direct me to those designing boards/electronics?

I'm finally about to launch into a build of linear actuated rocker style blast gates. I've been happy with the prototype I built last year. 451376

The rockers are built from whiteline 3mm MDF with...

I'm really keen to build something like this, so thanks for sharing this amazing and thoughtful build. It's on the list, but a long way down as the to do list is sooo long.

Have you considered using a DS18B20 digital temperature sensor rather than a thermocouple? They are easy to use with arduino and likely to work well in a noisy environment.

Well it's been a while (moving, new job, renovating etc.) but I can report some progress. Some time ago I built a rocker style gate that I could drive with a linear actuator. The actuator I have...

Well I’m making progress but much slower than anticipated. I’ve only been able to give a couple of days a fortnight to the project lately, although that will change.

I’ve finally received the CV1800 and unboxed it today. Did some prep work and preliminary assembly. Hoping to get it mounted tomorrow. After that I’ll need to organise a sparky and get the ducting...

Hi Graham99,

I'm not sure what you mean about restriction and sealing. The rocker mechanism seems to do both.

I know there are others who have gone the air cylinder route. It seemed to be as...

I've been testing a prototype gate with a couple of different motors I had on hand. The first one promised to have enough torque but didn't quite go the journey. It was a geared motor at 10RPM (or...

I’ve just about got a prototype ready for testing. I’ve been gathering components for the electronics required but the first proof of concept will be simple switching. I’m about to order a CV1800 to...

I may be able to help gatesy. PM sent.

I’ve never noticed a lack of torque with mine. I’m in Yarra Glen if you’re interested in comparing drive chains.

Thanks Bob. I’m inclined to go with two 6” fans in that case. I want to do this once and do it well.

It’s funny but I’ve never taken notice of those curtains before, it’s like they were never there. The house is a 70s child. Lots of retro love here [emoji16]

I've done some reading on the impeller fans and volume changes per hour.

My shed is 4.04mx7.22mx2.6m or about 75.9m^3

From that I've worked out that the impeller fans that BobL gave a link to...

Thanks for those notes and ideas Bob!

Yes, that’s missing because due to my lack of prowess at the moment with Fusion 360. It’s the first attempt at a model without reference to a tutorial. I intend to rebuild from scratch to aid...

I've been working on a couple of things - learning Fusion 360 and building a rocker gate prototype driven by a linear actuator.

I've modelled a rough version of it as shown in the images. The idea...

My experience of stepper motors is that they tend to have significantly less torque than other motors. That means they can easily slip a step when under stress.

Thanks Chris Parks for the Gilmer reference - that gives me another idea when thinking through the mechanical challenges of this. And ericks2, I'd thought about microswitches but hall effect sensors...

In order to keep this thread closer to its original topic, I've responded to the BobL's recent post in a thread dedicated to automated blast gates.

There has been some comment on the blast gate gallery thread about automating gates. As this is a bit off topic for there, it seemed better to revive this thread.

In particular, responding to this...

Thanks for the priority list here BobL. I'm still thinking about automated gates but like others there are a few more important projects taking my time and attention.

I've also concluded that #3...

Thanks Chris. With the right length levers I reckon a linear actuator might do the job without need of extra limit switches.

I’ve been thinking more about rocker style gates. If I can successfully drive one with a servo, micrswitches aren’t necessary for position feedback.

The challenge is minimising friction/load on...

I’ve been happy to let go of RC circuits for timing and instead flash code to a controller. Much easier! What length of delay do you suggest for a DE and what about an air filter in addition?

I wasn't aware of the clearvue 6" gates until you mentioned them. Do you have details on how you automated them? Pneumatic? How did you control them? Thanks.

I got caught out several times today with either the wrong gate open or multiple gates open ... I'll have a good look at that set up Bob. Thanks.

Thanks for both encouragement and a reality check Bob. I enjoy playing about like this, so I'm happy to spend a few hours to knock together a rough prototype. I knew it was important to ask before I...
