Sourcing/making an LCD front light guide?

I'm attempting to build a simple smartwatch in the style of a classic LCD digital watch. I've got a fully functional prototype using a Sharp memory display, a reflective display, but I can't work out a way to add a front light to see it at night. Years ago I had a cheap Kindle front light thing, and that was just a battery holder, a couple of LEDS and a sheet of transparent plastic, and worked surprisingly well. Trying just a bit of perspex gives me a nice glowing square on top of the display, but with nothing to guide the light perpendicular it doesn't show the screen.

It looks like I need a specific light guide with a fine structure on the side facing the panel. Could this be as simple as a fine polish to make the surface imperfect?

I've been looking Around AliExpress etc to see if any off the shelf plates or films exist, but it seems not, so it's either finding a commercial display to salvage from or find a way to DIY it.

You. You're awesome.

The person singing on the train, you're awesome. You with the multi coloured nails, you're awesome. You with the yellow phone case, you're awesome. You discussing football stuff, you're awesome. You're all awesome. I love just experiencing the people of Leeds.

Sourcing a Renesas DA148695MOD without huge delivery fees?

I've an idea for a project using one of these, and have been looking to get one to test with, but everywhere they stocks it seems to charge just as much for delivery.

The module itself is normally about £17 but the cheapest I have found in the UK is Farnell who charge £14 delivery.

Cheaper EV tariff if you have a Pod Point charger

I've not seen this mentioned before.

I recently switched to EDF and just changed to an EV tariff.

I was about to move to the standard one 6.99p overnight, when I discovered there is a specific version of you already have a Pod Point EV charger, it's identical to the standard EV apart from the overnight rate is 6.49p

Temporary EQB 250+, am I missing things or is it just a bit rubbish?

I've been sent a new EQB 250+ as a courtesy car while my own car is in for repair, thanks to someone running a red light.

I know some of this will be down to it being a 250, so low power and FWD.

Driving is fine as long as you're doing a steady speed, it's very soft, but rolls in corners.

Accelerating from standstill or low speeds, like joining a faster road is unnerving, it feels like it can't handle the power and becomes unstable and pulls to a side. On the flip side, if you are on a motorway and need to do say 60-70 to change lanes and overtake, it's gutless and takes forever.

The biggest issue is the throttle pedal delay. Everything happens about half a second after I've moved the pedal, so it's easy to overshoot what you meant to do and overcompensate. It's the same for acceleration, regen braking, and in all driving modes. The driving modes just change how aggressive the response is when it arrives.

Can't turn off creep, can't set one pedal driving?

The drivers display has very limited options on what it can display, I set up my own car to show media on the left, a single dial speed/power on the middle and navigation on the right. This appears to only let you have one thing in the middle, and only on the standard style. The others have empty space you can't use.

Also on space, there's not a lot of cabin storage. The strange rubber indent is too small for a phone, as is the covered space with a charging socket next to the cup holders. Centre armrest is an ok depth. Is this all a result of it being adapted from an ICE platform?

Door pockets seem small. Boot is tiny for such a massive car, and no under floor space for cables etc. Though it does have the two extra seats. Which seem to have no easy access? No frunk of course.

It's all just a bit underwhelming for a brand new EV, especially the driving experience.

Strange - haptic response from phone when using phone screen.

I'm sat in the car waiting for someone, I'm on my phone while listening to music via YouTube Music on AA.

If I press the thumbs up to like a track, my phone "clicks" a haptic response.

I thought it was just interesting!

Sigenstor and Freephase dynamic - missing data at 11pm each day

To be fair I only switched today, but for today and tomorrow the pattern is the same.

I've setup the tariff in the Sigenergy app, Freephase dynamic V2, and it's showing the cost graph, however at 11pm to midnight there's no data, so it looks like it's zero cost.

If I leave it on the AI mode like this, it'll try export everything and then charge the battery in the "free" hour.

Anyone else using this setup and can say if it will fix itself or needs something else?

Sigenergy AI thinks EDF Freephase is 23:00-00:00 every day

Title typo: thinks it's FREE everyday 23:00-00:00

I've just set this up, but the tariff import seems to get mixed up with the fact one of the windows is 23:00-06:00, so every day the house before midnight is blank and it assumes free electricity.

Any ideas on a fix?

u/sidneylopsides — 2 months ago

Does EDF freephase dynamic work with the AI mode?

I've done some googling and not found anyone discussing this tariff. Can the Sigenergy AI track this tariff?

Edit: silly me, there's actually an option for dynamic tariffs in the app and it specifically has the EDF ones.

Niggly faults - DIY fixes?

My steering wheel left side buttons right and diamond have stopped working, and the charging flap keeps showing as open

The wheel buttons looks like you can pop them out, but I suspect it's cable damage so might need the wheel off to get to the click spring stuff. Fuse 33 didn't fix it.

The flap I've read is a faulty switch, but not something you can access DIY, I've not found anything online suggesting someone has fixed this themselves. MY2021, UK.

Both are just a bit annoying but don't cause any real issues, I'd be happy to try fix them myself if anyone knows how.

New SEG and EDF

From what I can tell, to get the 15p export tariff I have to first register with EDF for the SEG on the basic 3p export, then email them to change over, have I got that right?

I assume this also means that any back dated export is at the 3p rate?

This is a new installation and we've not had export set up before.

I'm not attempting to get or give a code, just wanted to let people know as it's there, but it's a bit hidden and has to be used in the first 7 days of activation.

Installed today, couple of questions...

Has 29x Aiko 465W panels and a Sigenergy 8kW inverter and 2x9kWh batteries, in the garage.

For export do I just now find a tariff and apply? It seems EDF is best for the moment?

House is all electric, heatpump, EV, now solar and battery. So cheap overnight and good export seems to match what EDF are offering.

Also, this is specific and odd, but due to the Sig stuff being in the garage they added a WiFi repeater, it's working, connected to the app etc. But I want to hook it up to Home Assistant and I can't seem to find the WiFi repeater! It's now showing up in the eero app, and I don't want to reset it and run through it manually to find it as I don't know how the Sig is managed directly to get it to connect to it if I change something. I've sat scrolling the list while turning the repeater on and off and it just doesn't seem to appear. Weird.

Edit: Successfully added to Home Assistant, I realised the IP is in the the Sig app.

Call from the installer today about next steps and confirming MCS etc in the coming weeks. Happy with the system, been cloudy all day and still generated 39kWh so far, I've been topping up the car while I can earn from export.

Connection dropping in the afternoon for the last 3 days

We moved into a new build almost a year ago, and I brought my Talktalk account over. It's been fine, until Thursday.

​

About 5.40pm on Thursday the connection dropped, the ONT showing a flashing green PON light. Eventually that became a red LOS light.

​

Reported it, engineer booked. It started working somewhere around 10-11pm.

​

Friday morning about 8.20am the engineer turned up, but I had to take my kids to school. (Slot said 12-1pm when booked). He mentioned intermittent issues, did some checks and told my wife the level was "2 below minimum" or something similar.

​

Friday, connection failed about 4.30, same pattern of lights. Reported again, told they can't book an engineer as the previous job hasn't been updated yet.

Came back on about 9pm

​

Today, the connection was lost about 4.30pm, flashing PON light.

​

It seems odd that the fault is occuring around the same time each day, and resolving later at night. Could it be weather related? We've had some hot sunny days, it's making me wonder if there's a light leak affecting and already low level of signal, or heat building up during the day causing something to shift slightly.

​

Just wondering if anyone has experienced this before and has an idea?

​

Is it worth moving a vent for 1 extra panel?

We're getting solar and battery installed in a few weeks, but there's a bathroom extractor vent that would prevent one panel being fitted, which would mean 28 instead of 29 panels.

​

The vent could be moved to another part of the roof and allow for this extra panel. The scaffolding is going up the day before install, so I could potentially try find someone to move it before the panels go up, using the scaffolding.

​

The question really is it worth it? It's going to mean a difference between 13kWp Vs 13.5kWp and I currently have no idea how much moving the vent might cost... I need to try get some quotes today.

​

Anyone here experienced this?

Rearview trim removal for dashcam power?

I've been trying to remove this, but it's stuck part way off and seems solidly in place.

This is is a MY21 HSE. I have found guides for the type with the clamshell two halves, but this is different and just has single part that seems to come straight down, it's just stuck now.

I saw this recently, and was telling someone about it but can't find it!

It was a promo/advert, set in a rustic town hall. Maybe Amish? There was a guy pitching a new technology, internal combustion engines. The audience we're asking him if it was cleaner, more reliable, can fill up at home etc.

I've had no luck searching for it, and it's not in my YouTube history. I think I watched it in the Reddit app via a comment. I don't think it was for a specific car, more an awareness thing?
