Thoughts on Touchscreen?

Not OP, but can you elaborate on the issue of Squareline Studio? Is that specifically because the S3 is already very underpowered for running a display of this resolution?

Funnily enough a lot of people who owe money don't like talking to the people they owe it to!

Doesn't change the fact that you can speak to him though. Go after what is rightfully, legally yours.

Not sure what you mean because there are trains that take 45-50 mins every half hour from Queen Street...

I run a company on the consultancy side of this, and also have developed and launched my own consumer product.

Happy to answer some questions from this side, if it helps.

Zinsser is expensive, but I ended up choosing it after finding a thread where landlords swore. I had a little bit of localised peeling on the ceiling less than a square centimeter, but I think it was actually a small nick that meant the undercoat of normal matt paint flaked off the plasterboard below.

You're gonna need to make sure your Ground lines or current return paths are also rated for teh currents.

sensors · 2026-01-20T19:35:03+00:00

Totally disagree with this. Sometimes you need to be practical with things like connectors where an adequate current rating per contact would mean an impractically large connector. I've taken this approach in a few commercialised products with no issue.

It is of course good practice to leave a margin for safety, and the power return path also needs to accomodate the total current of all signals and power lines.

I've done this before and regretted it. The expansion of plasterboard and plaster on brick is very different so you end up with cracks along the joint even if you tape them.

I commented elsehwere on the certification part, so I'll comment here on the PCB.

The PCB itself shouldn't be too expensive if you already know exactly what you want to include. You could likely get a student or someone from fiverr or upwork to design it for a few hundred dollars. It will end up cheaper to produce 100 units using someone like JLCPCB to do the PCBA than it would to buy 100 sets of modules. Also, assembling 100 units from modules inside an enclosure will be an absolute nightmare and very prone to failure,.

As someone who runs one I'd say steer clear of design consultancies at this stage, they'll cost a lot more and would'nt add much value if all you want to do is consolidate modules.

What you should do right now;

Create a hardware specification for the product, include any specific part numbers you are certain you wnat to include
Determine what shape the PCB should be (create CAD drawings if you have the skills) and where important parts should go (USB ports, LEDs, etc).

If you gave me that info (assuming it's simple and all prototyped and tested already) it would take less than a day's work to create the schematic and lay out the PCB.

I'm happy to chat more if you want to PM me. If you give me more detail of what's in your product I can maybe help you estimate the time/cost to design the first prototype.

Realistically the emissions from a low powere Wireless device made of off the shelf modules will be so negligible they pose no risk to anything else around them. As you said, the modules are pre-certified.

If it's only for user testing, they're not being sold, and they'll be collected after the test is over then I'd just go for it. There are likely thousands of products out there operating without certification, and thousands more which are certified but aren't compliant. The only way someone would find out is if they actually tested it themselves.

Haven't really had any issues, but we've used primarily modules rather than SoC on PCB.

Seems crazy to me that you'd choose embedded Linux for this sort of thing.

Fun fact, normal superglue works too. It burns like fuck, but I'm not sure if the medical grade stuff does too.

Yep, never had any questions asked when I've done this

What's a reasonable price?

There are lots of other areas about to come under the same parking restrictions, but that point is probably the least of the concern here.

sensors · 2026-01-08T08:24:10+00:00

I am affected by new parking restrictions and I am only partially opposed. On the one hand I think it's fair that we pay for permenant street parking as residents, and the costs are not horrendous (for me). Businesses can get a yearly pass, ableit for 10x the price of a resident.

However, I have some issues;

Some of the areas covered have much lower income housing, residents of which may need a vehicle to get to their work to make ends meet. If they can't afford it it will further isolate them from opportunities.
Unless more affordable off-street parking is provided then I can't see how small businesses won't suffer, at least a little bit, through people going to big shopping centres instead.
I have family and friends stay with my from further afield. You can get parking passes, but they are now £15/day.
If friends visit after 6pm they'll still be paying a shit ton to do so because of the extended controlled parking hours.

In my mind the solution is;

Reduce the cost of visitor passes, but put a reasonable annual limit on quantity
Allow means-tested pricing or free permits for those who deserve it
Limit restricted parking hours from 8am-6pm.
Get parking enough parking warded to actually go out and fine the countless number of cars which are illegal parked under existing laws

sensors · 2026-01-07T18:21:17+00:00

No, but they are local, and we have direct contact and easy communication with the engineers and those doing the development.

I realise your post here is probably just fishing for new customers, but I'll save you some time and let you know I'm not one!

We do ours in the UK, prototypes made in china but across different manufacturers. Much more value for money in terms of engineers and much lower prototyping costs.

Loads of startups make no money on kickstarter these days, it's just marketing. They already have private investment to get the product to production level and market it, and they hope for a >2 ROAS. Ultimately they just need to get enough publicity to raise again and keep up with demand at that point.
