That's really cool! My plan is to build similar to yours but add more sensors and store the data on a microSD card.

[@monstersquashracing]

Let me get my popcorn. This stuff is fascinating.

[@MtGarage]

Glad someone else enjoys this stuff too!

[@pielumax3301]

looks great, I am just about looking for what sensor would be good for my subaru, just need a digital or analog sensor to measure my turbo pressure.

[@chochisnager]

Estás midiendo presión absoluta, pero ¿No sería mejor un sensor de presión manométrica (relativa), para que no afecte la altura sobre el nivel del mar a la lectura real de la admisión? Un saludo.

[@jeremyblubaugh3260]

Is there a way I contact you to get some help with my boost gauge? I'm having some issues. Thx!!

[@jacksonbartelli]

How is the PID.. if we set up example 2bar 29.4psi (relative pressure) will the controller adjust pwm up and down to keep the pressure stable?

[@MtGarage]

That's a good question that i don't know the answer to, sorry

[@jacobcammett]

How could you adapt this to work with a TFT color LCD display?

[@MtGarage]

The concept would be the same but you would just need to use the appropriate library for the TFT display you choose

[@aliej8839]

hey what is that boost sensor called? I am hard time finding one that looks like that

[@MtGarage]

It was from AliExpress. Here's a link:

Did part 2 ever come out?

[@MtGarage]

Yes it did!

[@sodomakgomora2995]

good work mate but at arduino project i read you say to use MPX4250 and he dont work with no atmosphere barometric pressure sensor.

[@gxk69]

Its possibel to put in bars?

[@MtGarage]

Yes it's definitely possible and pretty easy to do!

[@gxk69]

@@MtGarage sorry for late ansrew, how can i convert to bar?
tanks

[@802Garage]

Really cool little project! Now shrink everything down and reduce component cost to $5 and you can sell it for $100 with a brand label on it! 😂

[@MtGarage]

That's a great plan for someone much smarter than me!! I like the idea that it's open sourced and customizable for anyone to play around with

[@802Garage]

@@MtGarage Haha was mostly joking, because this demonstrates how simple some very expensive gauges are! Still too cool.

[@MtGarage]

That's true, but there's also some legitimacy to it!
