So hooked up 12VDC and Ground to J2 the other night to test my board.... as I am turning the pot to try to get some life out of the lcd, I smell electrical..... and noticed I let some 'Magic Smoke' out of my ATMega328 chip! Gonna look at the board under a magnifying glass for a solder...

If anyone has an appropriate router (WRT54G,GS or GL) for sale, please let me know. Coming up empty on Craigslist here and eBay isn't looking good either!

Oh Crap! Didn't realize that! Thought I was being slick! Yes the board and LCD will run without a router. With your IDE cable, remember that every other wire is a ground wire and are all connected together. I used an IDE cable, you just have to make sure you use the signal wires, not the...

Got my board all built yesterday and connected the 16 Pin J1 header on the board to the header on the LCD display using an old IDE cable. Am I able to test this without the router if I apply +12v and Ground to J2?

So...apparently my CDF1 WRT54G router doesn't have a serial connection on the board at all Only thing I saw was labeled JP2 and was the JTAG connection. Bummer! Guess I will have to look for a WRT54GS or GL

No it isn't bricked, it probably just does the same thing mine does 9 times out of 10 when I try to flash a new firmware on it. It will still take a new image but only over tftp to 192.168.1.1. You'll need to use the "linkmeter-wrt54g-squashfs.bin" image though, as the router bootloader only...

Hey Guys, have another question for you. I flashed my WRT54G v1.0 router with OpenWRT version 2.4 (as recommended in the guide for my router model on the OpenWRT website) and made all the NVRAM changes per website. Logged into Luci, went to the FlashFirmware tab and uploaded yesterdays build of...

Update: Got the HeaterMeter sketch uploaded without any problems to the microcontroller! Woo Hoo!! Now I just need my circuit board (Should be here Monday or Tuesday) and I can start putting it all together!! Pretty soon I will be automatically controlling my

Thanks for all your help Kyle & Bryan. Finally got my ATMEGA bootloader burned. I guess there are several ways to go about it. I followed the guide below the picture of the LinkMeter on Page 1 (How to program an AVR with another Arduino). I used the 16mhz resonator from the HM parts list on my...

Did you have the 16mhz oscillator connected to PB6(Pin #9) and PB7(Pin #10)?

Mine was reading ok with the 390 ohm pullup resistor in series with the reset line. So once I can communicate with the blank microcontroller, I can just use the Arduino software, goto Tools, board, Uno. Then go to Tools, Burn Bootloader, Arduino as ISP (using the Arduino ISP v4 sketch I...

Well....I think I see the problem. All I did was connect the microcontroller and made sure it was SEEN in avrdude. I think that I didn't actually burn the bootloader...duh! I believe I would just follow the part of the tutorial where it says Burn Arduino Bootloader using the command line...

I'm not sure what they mean by "optiboot does not support this sketch" but you can either try what Kyle Christensen did between pages 23-24 of this thread, which may work. OR I just considered that Optiloader might work. Upload that sketch to your Uno, then hook up the ATmega you want to...

Built my breadboard tonight with my ATMEGA chip on it hooked to my Arduino Uno so that I could burn the bootloader on the chip. I followed the instructables guide linked to on page 1 and am getting the 'Heartbeat' on my breadboard, but kept having issues trying to burn the bootloader...

1) Yes you only need one RFM12B on the receiver, but you also need one for each lmremote (wireless temp transmitter device). Each lmremote can have up to 6 probes plugged into it. HeaterMeter is still limited to displaying only 4 probes though, so even if you have 3 transmitters with 6 probes...

Thanks Bryan. I picked up a WRT54G v1 last week on Ebay for $12.50. Was just curious on the wireless probe issues. I bought a 3.1 board off of Duston and just ordered the rest of my parts today. Can't wait to get started!

Bryan, Had a couple of questions. In the parts list for the v3.1 board, you have the RFMB12. So you only need 1 of these on the board? How many wireless temp. probes can you connect at once? Where do I find the probes themselves? Also, for someone just starting from scratch on this project...

It it is a version 6, the Wikipedia page for WRT54G says that it only has 2MB of flash and 8MB of RAM. The standard LinkMeter image is 3.2MB so you'll have to build your own, stripping out as much as possible. I know someone has done it, but I don't know what the final config was. Also 8MB of...

OK, couple of questions for anyone who wants to answer 1) I remember seeing a thread on here showing the different version of Linksys WRT54G routers (for using in this application) and now, through all my searches, I cannot find it. I picked up a Version 6 yesterday with High-Gain antennas and...

Hey Bryan, First off I want to say NICE WORK!! Been lurking around this project trying to decide if it is within my capabilities and I think I have decided to try it. I have one question for you though....how hard would it be to build this project using an arduino uno board instead of building...
