Dead Car Battery Recovery – Charging

Recover your dead car battery with a custom constant current / constant voltage power supply.

A regular charger will not charge a battery that was siting a long time and reached a very low voltage but this can!
After bringing it to normal voltage 10v to 12V, you can continue the charge with your regular car charger.

X5460 Mod – 3.8 GHz on Abit IP-35 Overclock Xeon

Overclocking the Xeon X5460 3.8 GHz on Abit IP-35 with 8GB OCZ Reaper RAM.

Here are the settings I use for my PC build.

A few tips:

  • The DRAM voltage is for OCZ Reaper (requires 2.2V) yours might be different.
  • If you apply the sticker yourself, be extra careful to place it in the correct position, see video.
  • Do not to bend any pins in the CPU socket when you cut the plastic tabs, video.
  • Try to keep the RAM frequency bellow the rated speed. Don’t OC your RAM.
  • If the NB on the motherboard gets too hot when you overclock, it will need extra cooling. Too hot is when you can’t keep your finger on it for a few seconds.
  • Increase the CPU voltage in small steps if you need to. I didn’t really need to do this.

Mod the LGA 775 Motherboard to accept a LGA 771 CPU

Xeon X5460 Running with 3 sticks of RAM, OCZ Reaper. Later I added 1 more RAM module totaling 8GB installed memory

 

On Abit IP-35, if the bios contains both LGA 775 and LGA 771 micorcodes, it will not work with Windows 8.1 and higher. Windows 8 and bellow still work even if the microcodes are for both platforms in the bios.

ONLY FOR ABIT IP-35 – Moding the bios – E0

I have modded the last bios(the E0 version) released for this MB, to include only 45nm processors on platform 771, removing the 775 45nm.

This can work with other processors but I have not tested it.

As far as I know, E0 is the last supported stepping on ABIT-IP35.

The last bios that was released for this MB is considered by some to be v18 but that’s WRONG. There was an E0 version that included both 775 and 771 CPU microcodes.

These are the microcodes of the original bios:

diyrno_M630A_e0_orig_microcodes_150813
diyrno_M630A_e0_orig_microcodes_150813

The mod consists of removing the CPUID 1067A – Plat 0,4 – that is 45nm CPUs on LGA775

The modded bios contents:

diyrno_bios_771only_edited_e0771M630A_170127
diyrno_bios_771only_edited_e0771M630A_170127

Now only CPUID 1067A is on Plat 2,6 – meaning LGA771 socket and 45nm CPU.

Download modded BIOS

This is the bios file already modded, just needs to be flashed – use only after reading all warnings bellow!

Now, please, PLEASE note that YOU ARE DOING THIS AT YOUR OWN RISK!

YOUR COMPUTER MAY NOT WORK AFTER USING THIS MODDED BIOS.

YOU ARE RESPONSIBLE FOR YOUR OWN ACTIONS!

IF YOU DON’T KNOW WHAT YOU ARE DOING STOP NOW!

THIS BIOS IS ONLY FOR ABIT IP-35 AND MIGHT WORK ON IP35-E(but I’have not tested it on that MB),   —  IT WILL NOT WORK  FOR  THE  I-P-35 -PRO

UV LED Array Exposure Box DIY Build

Building a UV LED Array and a PCB exposure box out of cardboard.. yeah.

This UV LED Array and box pcb are DIY home built 🙂 with a simple design.

This exposes a PCB in 2,5 – 3 min using aproximately 1,2A at 12V

I use a 2A 15V power supply that powers a simple LM317T constant current module that keeps the LEDs from burning out.

Constant current is at about 1-1,2A, 12V.

R1 is 1 Ohm and at least 2W.

power_schematic_edit

Led Current(I) = 1.25/ R1

Where 1.25 is the reference voltage of the LM317.

If you want to use the bellow PCB design, you are free to do so and if you want, please share this page 🙂

Right click and download the bellow 2 images, they are PNG – 1200dpi.
