NMEA 2000 Engine Monitoring Unit - Analog to NMEA2000 Engine Gateway
Share engine information on the NMEA 2000 bus.
The Actisense EMU-1 is a specialized analogue to NMEA 2000 Gateway which converts data from analogue engine gauges/senders into NMEA 2000 data. The EMU-1 enables the sharing of engine data throughout the NMEA 2000 bus. It digitizes analogue engine sensors, enabling NMEA 2000 display devices to monitor the connected engine(s) on a vessel.
The EMU-1 can monitor vital engine parameters such as temperature, pressure RPM and fluid levels from up to two engines.
The EMU-1 has a PC-based configuration tool that allows the settings inside the EMU-1 to be changed to best suit the engine it is working with, making it a flexible solution for many engine makes and models.
An Actisense PC to NMEA 2000 Gateway (NGX-1/NGT-1) is required to configure the EMU-1.
The NGX-1 or NGT-1 must be used to update the firmware, connect the Toolkit and display data on a PC for diagnostic and information purposes, using NMEA Reader. Please visit the NGX-1 page and/or NGT-1 page for product details.

Addicting!
Format: Kindle
I could not stop reading. It was so refreshing to have a series start so completely different than most fated mates/fantasy academy rh I’ve been reading. From the desert scenery to the magic and feeding plus the psychological trauma the characters are there to deal with. Pandora is absolutely adorable and I totally relate to hiding behind my hair. I love that she’s literally the most scary type of demon but it’s not the usual “badass mc” persona (which I do love a badass that can fend for herself and kick ass from the start but it was a nice change of pace). I’m not usually a big fan of bully within the harem but each character has their reasons for their actions and also conflicting feelings about them. I adore Dex and Reed! Complete opposites but their personalities and inner monologues made them instant favs. I can’t wait to see the character growth with the guys and continued strength for Pandora.
The captivating characters and references to the Fate Hallow series added so much depth and now I need another reread while I wait for book 2. The concept of magic and the unique feeding habits of the demon characters were intriguing. I can't wait for the next book to continue this thrilling journey.
In summary, this book is a must-read for fantasy and magic academy rh fans. With its enchanting characters, nods to the Fate Hallow series, and imaginative concepts, it offers an immersive reading experience that hwill leave you craving for more.

Best academy I've read this year
Format: Kindle
I need a few things when it comes to a first book of a PNR romance series
1-Good world building (which this totally did)
2-An FMC I can root for (oh hell yes, Pandora is someone I can cheer for)
3-Good drama (can you say GROVEL BOYS!)
4-Enough story to make you feel like you really read something with meat (you saw this book is like 600 pages, yeah?)
5-A hook at the end so I want more! (please, Lyra, gimmie more?!? I need more!!)
Be aware this book is a slow burn, but damn do I feel like there'll be some big payoff when it finally happens. Who doesn't like the buildup?

Pandora’s Pain, Power, and Passion
Format: Kindle
I absolutely love this new world Lyra Winters has created! The spin on a Demon Academy setting was fresh, unique, and completely addictive.
Pandora is a character who immediately captured my heart. Thought to be powerless and enduring years of brutal abuse from her mother, it’s no surprise that her powers emerge at the exact moment she needs them most. After her mother’s death, Pandora discovers her father is none other than Death himself, a soul eater with a dark legacy. Her journey at the academy is anything but easy, filled with challenges tied to her father’s infamous reputation, her barely controlled abilities, and the cruelty of those around her.
Pandora is easy to root for, you feel every ounce of her pain, resilience, and growth. Along the way she meets Reed, a half-human dream demon who’s kind, steady, and the kind of friend everyone wishes they had. There’s also Hunter, a vengeance demon and counselor connected to her father, who adds another intriguing layer to her story. Then there are the bullies: Dexter, a brooding shadow demon; Bram, a chaos demon with a drinking problem and deep hatred for demon nobility; and Skel, a fear demon wrestling with his own darkness. They might hurt her, but they also can’t seem to stay away when she’s in danger, making for some deliciously complicated dynamics.
This book hits so many of my favorite tropes: friends to lovers, enemies to lovers, and of course, the irresistible “who hurt you?” storyline. I devoured it, and I’m already diving straight into book two!

So good!
Format: Kindle
Oh my goodness! What did I just read? Lyra Winters you have some serious explaining to do! That cliffhanger killed me! I am so happy to be back in the world of Kalista. This is definitely darker than Fates Hollow but oh so good. This is a fated mates reverse harem which I absolutely love.
Pandora had a very hard and rough upbringing. She lives in pain constantly and it makes it hard on her. She struggles with everything because she was kept so isolated and is new to her magic. Pandora gets sent to the Reform Academy and all of them have reasons why they are there. I love how, after everything she has been through, she is still a nice person. She is growing and becoming stronger too. Love her character.
The guys all act like jerks at first but all have a back story that helps understand why even though want to smack them. I'm here for the groveling that I'm sure will come. I love them all. They each bring something for her. They are all drawn to her though.
This is a slow burn book but there will be more books in the series so sure it will build. Man, that cliffhanger was a doozy and need book 2 now!

Good-ish
Format: Kindle
🌶️ 0/5
⭐️ 3/5
I will preface this by saying I am not a huge RH fan. However it didn’t feel like a RH quite yet. The relationships and plot are all building in this book. At first I was thinking things were happening stupid fast since she’s had zero interaction with another being and has been tortured her whole life, and I believe they were for one side of the relationship, but by 50% things moved too slow lol. Idk I think the main 1-3 guys I’m actually interested in more than the others didn’t get enough air time so I hope the next book things start moving with them since it ended the way it did.
