no, relays. No idea how to make a transistor do the same thing TBH

off topic BUT I had some TINY 12v relays turn up yesterday. something like 7mm x 8mm x6mm.. so awesome.

Out of curiosity- What is the purpose of the diode in your LM7805 circuit? the LM7805 is fine (and cheap) i just went with the larger one because in the specs somewhere it used the word "beast" in relation to its 5A output capacity....I'm a sucker. The Lm7805 has overtemp and over current protection so really is a bloody good deal.

http://nz.rs-online.com/web/p/products/5339331/ I have just ordered some of these. General consensus seems to be that they are a far more reliable (and smaller, if it matters) option than the adjustable chinese regulators. To be fair- I'm unsure how easy they are to use and if they are stand alone regulators or need to be part of a larger system

Yum.

I have had a huge amount of success since these last posts- my biggest is a change from the CRAP adafruit library to the one on this link https://github.com/sumotoy/SSD_13XX/blob/master/README.md This new library is fuggin amazing- a tiny change and my benchmark drops from the 33 seconds I was happy about above to FOUR SECONDS. I'm now happy I took the time to produce the quick benchmark program and actually record the times. All logos/warning lamps are now BMP files converted to code like this I was starting to lose interest because it took a visible amount of time to draw each icon! now they appear instantly..oh and theres a seriously wanky startup logo now

Obviously needs to replace glovebox with a leather pouch

No point having all that power if the glovebox cant handle it. what a waste of money

Pics plz

This isn't anything new or DIY related (unless you want it to be, of course) Msd and others do these units, they are very available. Google two step ignition

Oh I thought it was cheap... Soz

Wow that is suuuuper nice! For some reason i was expecting any color but that beautiful blue.

I found the problem (I think) The libraries share a timer. Anyway.. have soldered one nano to a plug and put it into a box..

How about changing diff ratios? To get some more rpms. I also am surprised it's as bad as you say... I do worry that you could spend lots of money and get fuck all gains.. why don't ya get it on a Dyno and see if hp is where it should be and ask them if they have had na 2js on there that they could compare it with. Even a decent tunable ECU may way it up better than a swap.

Hi guys,. Okay, two simple (probably related problems that i cant solve via google) I decided to use the tone function to reproduce the oldschool CLICK sound that would happen when indicating. The code is extremely basic and near impossible to fopar HOWEVER it makes my whole program extremely unstable which leads to the screen randomly displaying garbled garbage which DOES NOT rectify itself on reset. The second issue was with a simple piece of code that played a series of around 10 tones with ever increasing pitch. If i leave the arduino looping the code and playing the tone sequence over and over EVENTUALLY it starts either skipping notes or simply playing notes at random times out of sequence. Any idea what could be up here? I'm using a little buzzer piezo thing from a PC without a resistor... could it be drawing too much juice and making shit go bad that way?

that sounds like a waste of time. Swapmeet purchase?

I feel like gregs post didn't do Chrome justice- What an awesome day! There were a few issues but would have felt strange if there wasn't. Dunno if i should share my vids here..Feeling insanely pissed off because a few of them have gone missing/been deleted accidentally

Nailed this issue Was looking through an example and noticed this in the sketch A simple copy paste to change from option 1 to option 2 and its away I copy pasted out a long benchmark (just filling the screen with different colors over and over) with a time running counter displayed at the end and tested the two options. before it took 153 seconds to run the sketch, got that down to 33 seconds

thanks guys. I think at the moment it is SPI. Will double check things. Good idea about argument Ned!

Wait.. is this EFI or not lol So cool tho

Hi @Scrubb. Is that directed at me or someone else? @h4nd I could never get the drop-through code to work nicely and have moved onto trying other new things. I guess its not ever going to be a real issue for this code because its so basic AND there is nothing critical happening that will get upset if there is a small delay. (eg If the battery icon takes half a second to pop up- who cares) I have tried using the software you suggested but i'm a real Barry these days- the basic normal IDE is so much easier for me to navigate round and learn in. I haven't had a day off for a while so progress is slow but this is the code I now have working well enough to prove I can do it. No longer using external resistors, using an OLED rather than TFT and drawing the icons using the line command rather than triangles and squares. Only two icons because they are being redone again once the larger OLED arrives. Compared to the TFT the OLED seems to have an extremely slow communication speed with the arduino. Even the various Youtube tutorials show the same issue but offer no explanation. This is the reason for changing from SOLID objects to simple outlines- must be less data to send. and this is what it does.

Thanks guys. I have moved on to an oled screen.. FAR FAR FAR nicer than the TFT I was using- because the TFT has terrible viewing angle. @ajg193 thanks I'll look into those too
