Just to note that the actual water block will be cooling RAM and not the CPU.. R-Pi uses a sandwiched CPU RAM design... PCB|8|CPU|8|RAM|watter...
What's the max power consumption of your rig? tje adafruit ones are goot doe 440W of mains power, assuming 85% efficiency of the power supply...
will you be adding any electronics to the board like a shield. Or is the board capable of doing all that you specified by itself?
Keep in mind that you would be connection the PSU/motherboard ground to the mains EARTH wire...I am pretty sure this is a big no no...
Hi, great pics, and an awesome build, I have a request I hope you can help me out with. I am building a fan controller and I 'd like to see how...
the dropout for 78xx IC is 2V, as long as the input is above 11V the regulator will keep its output at 9V.
My concern had more to do with the noise that will result for the power supply voltage swinging in tune with the current used, even with a...
my advice use a regulator chip, 7809 add two 0.1uF (16+V) caps, one from Vin to gnd, and the other from Vout to gnd, keep them as close to the IC...
here is a similar project that might help you out.
I think the standard arduino uses a ftdi chip to emulate a serial port. So data is sent to the computer over a serial port. I don't think its...
here is a cool open source project for a DIY soldering station that suports PTC and K-type soldering irons. Hakko/compatables and Solomon are the...
here are a few depending on your skill with microcontrollers. probably the cheapest solution would be a Atmel or Microchip uC with on board usb....
Thanks for the info, I'll look into it. Btw sorry for not updating this post. I am waiting on some development boards to arive, and I'll start...
those are some serious devices you should expect them to cost a few hundred dollars at least.
No problems, least I could do
commercial DAQ and DSO are grossly overpriced, but at least you get someone to shout at if something goes wrong :) The Bus Pirate is must have...
for such low speed <10MSps any high speed USB DAQ can handle it, and its probably a lot cheaper and practical, then a PCI or PCIe card. For the...
I know it can be read from the RPM, but you would have to compare the output voltage to the duty cycle of the PWM....but with current and voltage...
I'll use the UDN298x part because it is high side (good for buck), and it can be run directly from the PIC. since current limiting is now just on...
You could try using multiple transistors in parallel and then heat sinking each one it should be ok if you use 3 of them for 20W a piece, I...
