Hi,
I somehow managed to wipe my bootloader. I think I managed to program the bootloader again using the AVR Pocket Programmer and the DiskLoader-Leonardo.hex file in the Arduino/hardware/arduino/bootloader/diskloader folder, but since then I cannot connect it to my Windows 7x64 machine. In the Device manager I get "Unknown Device" under the USB controllers, Error Code is 43. I tried uninstalling, re-installing - nothing works. If I tryt to upgrade the driver, windows tells me that the driver software is up to date and shows it as "Unknown Device". I removed all oem.inf files in the Windows/inf folder which referred to Sparkfun micro pro or Leonardo.Up until the bootloader incident, all was just dandy.So, any ideas of what I messed up and how I could get it back working again? Does the Pro Micro need a special bootloader or can I use the one from the Arduino collection?
Please help.

Hi,
I would like to utilize this board Dual Axis Magnetic Sensor Eval Board - Honeywell HMC1052L sku: SEN-00761 (or something similar) in a device that would be lowered to the bottom of a water well (i.e., it will get wet).I anticipate that I would encase it in some sort of epoxy or silicon caulk as a water-proofing. Would this provide sufficient protection and keep the unit within the humidity specs provided there is no breach in the epoxy?
Please help.

Hi,
I'm rather desperate at the moment. Since last year a computer died on me, it's replacement motherbord also died on me. A totally new (self-built) system also was dead when i connected it, and now, my fourth computer: a 2nd hand iMac, upon connecting it, albeit not instantly, but after a few boot up lockups it died on me.In all cases, the original system, the replacement motherboard, the entirely new system, and now the imac, i only get the fans to turn on. No prompting. The only exception has been the iMac, which, with great difficulty booted a few times before locking up. Now it seems dead like the others before it, save the fans. The financial damage is getting close to a 1000 usd by now, i am really beyond desperate.First i thought there was an issue with the original mainboard as it was a board with a lot of troubles and a lot of replacements already before i moved to where i live now. After the new system died again i suspected it to be the PSU so decided to go for an entirely new system. And now, to me, the only possibility seems to be the ungrounded outlets. Or this house i live in is cursed. I live in a rather old house so wiring might be old and instable?I dont have any issues with my other electronics. I do use a premium 8 hole extension box that i think should prevent against shorting?
Please help.

Hi,
We're finally moving into a house in a couple weeks and I am thinking about saving space by putting some components of our LAN down in the basement. This would be: 1) the cable modem; 2) the router; 3) the file server (4xHDD in a Lite-On FS020 case).My question is this: how damaging is the sort of humidity you find in a typical East Coast basement? I haven't yet measured the humidity, but I know that:the lady who just moved out found it necessary to run a dehumidifier down there, and the foundation is leaky enough that now while all this snow is melting we're gettting lines of water coming in from the base of the basement walls (yeah, the place has its problems, I know; we're renting, not buying).I have no experience with this issue so I'm wondering if someone can clue me in as to whether I am asking for trouble putting computers down in a sort of damp basement or if it's no big deal or what. Do I need to know RH or is the idea ruled out simply by the fact that the place is a basement?
Please help.
