So an updated version of DigiHUD Pro was released the other day to fix a couple of bugs and add some new features (take a look in the Play Store listing for the details).

I also was required by Google to ensure my apps target Android 8.0 if updated from 1st November 2018:

 

It’s taken so long to get this update out because Google have made it increasingly difficult impossible to support the later versions of Android and use a third-party development environment, which in my case was Eclipse. I’ve nothing against using Google’s Android Studio it’s just that everything was setup perfectly and I was happy the way it was.

I resigned myself to the fact I had to switch and set about migrating. Oh if only it was a one-click job! Being new to Android Studio meant having to learn how everything worked whilst I re-created the apps in it. What a nightmare that was.

I digress. I realise now that a simple run-through of the app just wasn’t enough and that I hadn’t understood the gravity of moving to the later APIs. Some things that have worked since day one are now broken and I must either find a way to fix them, or remove them.

Here’s an example.. You can get the app to start when the device is connected to power, and you can get it to close the app when it disconnects. It was really simple to implement using system ‘Broadcasts’ (think “Hey everyone, the power got connected”), and “Receivers” (“The power was connected, I need to do XYZ”). This has now changed, I believe to reduce the amount of processing apps do while they are idle in the background or when not running at all. It helps reduce battery use which, of course, is a good thing.

Unfortunately these were two of the features I didn’t think to test on an Android 8 or 9 device.

Hopefully the next update will be out soon.

 

 

I had an email from Eric Lee over at Hudly to let me know that the team at Hudly are working on a sleek new wireless model and it’s up on Kickstarter now.

Go check it out here: https://www.kickstarter.com/projects/ericshun/hudly-wireless-focus-on-the-road

DigiHUD looks great on it’s large 6.2″ display.

I received an email today from Hudly again thanking me for being a backer but also to say that backer’s units have now shipped.

I’m not sure how long it will take for my unit to make it’s way from the USA to the UK, hopefully not too long as I’m dying to get it installed and see first hand how well it works. I’ll probably have to pay import duty on it however.

I’m super excited to get my hands on Hudly, however I’m not sure yet if my Android LG G5 will be compatible with it as it uses MHL to connect Android devices. I’m sure I’ll be able to use my Galaxy SIII.

I’ll add a write-up on the unit to this blog after putting it through it’s paces.

 

Fancy getting Hudly?

As anyone who has tried to use DigiHUD’s HUD mode in the day will confirm, it’s not really usable because it get’s washed out to the point where it becomes invisible. Add to this the slight double image caused by the laminated glass and it’s a non-starter.

In order to work well in the day, commercially available HUD units have particularly bright displays (generally brighter than smartphone or tablet screens) and also a piece of slightly reflective film which is stuck to the inside of the windscreen. The film removes the double image and also allows the display to be seen in bright light.

Recently I picked up a piece of film from that popular Internet auction site to see if it improves DigiHUD’s HUD experience.

Here it is in the day.

I’ve attached it up high on the screen because the rake of the glass would mean the film was a bit too much in my line of sight for comfort. I will at some point 3D-Print a holder for my phone to sit on the dashboard.

So for a few pounds it makes a world of difference to using HUD mode in the day.

Hudly is a new full-colour heads-up display system that’s raising funds on Kickstarter right now so that it can go into mass-production later this year.

It comprises a projector unit and a glass ‘combiner’ which is used to display the full colour projected image in front of the driver.

DigiHUD, like other smartphone apps, works incredibly well with Hudly and we were so impressed to see it in action.

Hudly also connects to the vehicle diagnostic (OBD2) port to show information right from the ECU, like fuel quantity remaining, engine revs, outside temperature, mpg etc.

It’s recently been featured in the press, including TechCrunch, TopGear, Stuff.tv and GadgetFlow.

DigiHUD is proud to be a backer of Hudly. The Kickstarter, which tells you everything you need to know about Hudly can be found via this link.

Update: To help raise awareness of the campaign, the free version of DigiHUD now includes a simple popup which links directly to the Kickstarter. This one-time popup is shown the first time HUD mode is selected. It’s also available from the Menu.

 

I’ve swapped out the head unit in my new car for a brand I’d never heard of before – AutoPumpkin. It’s relatively low priced yet has plenty of features and connectivity options. I bought it because the unit that was in the car (a JDM Clarion) was a CD and Mini Disc player, but only Japanese Mini Discs..

I also wanted a DVD player to play movies on the rear roof mounted screen to keep the youngsters happy on long journeys. Having one that runs Android was also a win because I can run DigiHUD on a larger screen than my Galaxy S3s, and it just comes on automatically so no need to set it up when going for a drive. I play music over Bluetooth which can be controlled by my phone.

I plan to install a couple of blind-spot cameras later on which can be fed into the Pumpkin. It doesn’t have DAB radio (separete module is available) and the AV out is only for the DVD but overall I’m very happy indeed with the unit.

If you plan on using this app to give you accurate readings that you need to rely on for some reason then calibrating the device or comparing it with a calibrated device is essential.

DigiHUD app doesn’t know how accurate the GPS data is that it receives and doesn’t make any allowances for inaccuracies in the data. All the app does is display what the (usually cheap, low-cost, low precision) GPS sensor is telling it to. So if the sensor is inaccurate then the app will be too.

I use the app every day (well, every car journey actually) and because I use a high precision GPS receiver, and also because DigiHUD matches exactly several local roadside speed warning signs, I’m very comfortable that the speed I’m travelling is accurate enough for me. If the accuracy was unknown then I’d be uneasy travelling on the speed limit.

So please remember the following, taken from the app’s Help text:

Although we strive to make all readings as accurate as possible they are only as accurate as your device’s sensors and should only be regarded as approximations.

I saw a review of the free version of DigiHUD today that mentioned the maximum value of the trip counters. Here’s Ryan Scott’s review:

Really like this app and use it exclusively to accurately log mileage on my Dodge diesel to track mpg’s. I only give it 4 stars due to trip meters only reading in the thousands. I would consider paying for the pro version if the trip meters read higher.

I realised that it’s not in the description or the app itself what the maximum values are, for either the free or Pro version. It’s impossible to put everything that the app can do into the description because of the character limit.

Putting it all in the app itself is either too late (because it won’t be installed if you don’t know about some ‘killer feature’) or it just won’t be seen. Nobody wants to read a huge pile of text about what the app can do or how to use it, I get that, and apps should be intuitive and not need instruction manuals. You probably don’t want to see a huge window open when you start the app listing its features and giving instructions on how to use it.

Here’s a Pro screenshot showing how the values can be set to show greater precision and also the number of digits the trip counters can have. That’s a million miles/kilometres.

It’s worth mentioning that the free version also shows some values to two decimal places when in landscape view.
