I made this red-dot mount for my bow.

You got it right in my opinion

I heard installation was a breeze

Where do ya buy ur stuff from to do that for $1? (sorry to go so off topic chris)

Hey man. Should just use an arduino nano. Probably cheaper and infinately more variable.

damn that interior looks comfortable!

I do hope this doesn't happen as the melting temp of the glue is around 150 degrees

I am REALLY happy with how this has turned out. MY PCB/little relays work as they should and its all been potted in hot glue and tests A+. I ended up using a little LM1084 voltage regulator and some little capacitors and tiny prototype board to get down to 5v. The relay PCB is wired to the arduino using little wires salvaged from a broken USB cable Basically- the wires coming out of the left just get connected to switches in the vehicle (like the handbrake or gear indicator switches) and the wires on the right get fed 12v to close the relays switch (eg, 12v from the headlights ) I used hot melt glue because it was cheap, fast and easy (pretty much my life motto). It looked like shit until baked in the oven for 10 minutes at a low temp. Its an awesome thing to do on electrical shit like this and its turned from being a fragile heap of shit to a robust heap of shit.

Bought some solder paste and cooked things on an element. Probably got it all too hot but wont know until i test it All the connections and tracks work

definately try running it first before you go bore it larger and fuck it LOL

I do know they wear very quickly. And are expected to go out of tolerance fairly quickly. I worked with a guy who raced nitro buggies. To save on rebuild costs he had machined a tool that would accurately crush/ squeeze the liner to get the bore back into tolerance. Seemed to work pretty well! ( He also machined his own heads with huge heatsink fins so he could run more aggressive fuels)

Thanks Ned! Hope you are well

Looks like its only for TFT displays which (in my opinion) are fuckin terrible for auto application due to very narrow viewing angle (on the few that i have seen anyway) . I'm not sure if large OLED screens are even available but they are really the only type worth spending money on The slow processing speeds are not really a problem if you design your interface to compensate- EG make the information to be sent as small as possible.

I used Circuit Maker but then sent it to work email as a PDF, then imported into CAD, resized it to scale and then printed. To be honest I must have tried about 5 programs and all of them seemed difficult as hell to use. I understand people might need auto routing and 1 million layers etc but I didn't and the complexity sucked. I couldn't even work out how to change track width so ended up with these tiny lines that could have been 2x the width. About ironing on the laser print- I tried about 5 times- my first attempt was half adhered. My second attempt is the one i used. My 3rd, 4th and 5th attempts were worse than the first despite trying every single tip I could find (getting the copper super clean, scuffing with steel wool, water, soap, dipping in acid etc etc etc) Am a little tempted to send the file to a professional and just spending the $$ to get it done nicely with pre drilled holes etc.

I made a little PCB!! This one is the result of my second attempt at ironing the transfer to the copper. it was not perfect but good enough for me- unfortunately my sharpie has a thick tip so was hard to touch up any missed bits. This will hold my 6 little relays.

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
