Re: 1983 Sierra XR4i
Perfect donor for a Cosworth BOA / BOB engine swap, the engine should bolt up to the manual gearbox. I have looked into Ford Sierra XR4i's as they are the perfect donor for a Cosworth BOA / BOB engine. The Cosworth V6 is very cheap and easy to find, but they were only available with an automatic gea...

Re: sim's Volvo 245
Offtopic: I really like the new FTDI FT230XS bare-bones USB -> Serial chip. Very simple BOM: only need decoupling / filtering and Windows finds drivers automagically. Also in DIY friendly SSOP package. My standard choice now

Re: Power Supply Design - Input Protection Scheme
The way I 'read' the schematic, it will protect the +5vSwitched from over voltage (and, as has been mentioned, the 5v6 Zener looks somewhat superfluous now). However, it will NOT protect the +5vTPS and +5vAux lines at all. Correct, as the +5V TPS and +5V AUX lines go directly to the connector to th...

Re: Power Supply Design - Input Protection Scheme
Huff/Fred/Others, Corrected schematic for you! http://i183.photobucket.com/albums/x115/ae86dragracer/Idea3_zps79d4079a.png Cheers, Dan With this schematic I think the 5v6 zener can be omitted as it will never come into action If I get this correctly the TIP42 is secured by the polyfuse ? Because th...

I think malcom2073's releases are built for release version of the QT lib, while your build are most likely built for debug version of QT Lib.Fred wrote:
I can run it from source, so your deps are wrong/excessive.
Fred.
Are you sure you have the release version of QT lib as well ?

Re: Power Supply Design - Input Protection Scheme
Thanks! Do you have any thoughts/feedback on my dual Zener plus current limit idea? I must check tolerances on Zener diodes and Current / voltage diagrams to see how much a 5V1 Zener leaks at 5V If the 5V1 zener leaks and dissipates more than 50mW it will mean extra heat in the box, which is someth...

Re: RGB dashboard backlight (disco disco huh huh)
Cool idea, I had the same idea some time ago and then basically thought: "It will take too much time" I think you experienced that ;) Nice you kept going. For the design I have some questions: Why a 5V power supply ? A 3.3V power supply seems much more logical to me as the dissipation in t...

I do not want to be rude but....do you know the MC34152 features a undervoltage lockout at 5.8V?Dan wrote:Testing of the MC34152 ondifferent levels of supply voltage (5V, 12V, 14.4V, etc).
