Re: DD-WRT: Installing Optware

Awesome! Glad its working for you.

I'm going to do a video soon on setting up transmission in optware and possibly pixlserv, squid and a few other things.

Re: Arduino/ATMega based Digital Soldering station

Why not measure the output of the thermocouple on the board I have? Also setting up the circuits on a breadboard and measuring the output with an oscilloscope when applying a sine wave from my signal generator seems like a decent idea. Also, as a thought, how does your soldering station measure the ...

Re: Arduino/ATMega based Digital Soldering station

It looks like based on the simulations that the current design isn't dropping much below 5v. Peak is at 4.996, the minimum is 4.968v. That's not ideal. And even if it was the proper voltage its not replicating the sine wave very well. If you want, I have some lm358s somewhere, they might be in the b...

Odd buick 3300 engine issues. high idle, hesitating, etc.

So my wifes car is acting weird. You start it up, sometimes it runs great, idles good and seems perfectly normal. Other times however it acts like its misfiring, sputtering and idling at about 1200-1300 rpm as indicated by a scan tool. The IAC valve position climbs higher and higher and topped out a...

Re: New Transistor Tester design

Very cool! I need to get figured out why my toner keeps separating from my boards.no sand them, clean them with paint thinner and let them dry, apply the paper and laminate it until the cows come home. Then it peels off halfway through my etch. I'm going to try different paper, then maybe try a diff...

Re: PCB Etching with Laser printers and Laminators

I've thought some more on this. I think I actually want a resistor bridging the wires, to keep the voltage slightly higher thus fooling the controller into thinking the rollers aren't hot enough. I'm not great with electrical theory, so I may be wrong. If this is the case then a spst switch with a r...

Re: Few Circuit Ideas

I need to build one of those power supply's sometime, I'm trying to figure out the best way to charge a couple battery powered shavers I got at a yard sale. I believe they require 15v input, and nothing I can find puts out 15v, everything I've got is either 12 and under or 24v, nothing in between.

Re: Answering the Telephone

If they call you back keep in mind what dad once told me: "If it isn't worth doing, don't do it" Exactly my thoughts. I was saying the other day if they call me and want me to come do stuff I'll be either charging a $50 trip charge for every time i go over, plus $35 per hour. before 9am or after 5p...

Re: B+K Precision 15MHz Oscilloscope Repair

Iiiittttsssss ALIVE!!!!!!!!! So the first thing was figuring out what was actually wrong with it. The b channel showed nothing. Just a flat trace. The a channel was sometimes kinda buggy too for no apparent reason. Turns out there was a resistor (q154 470 ohm on the schematic, under a metal cover on...

Arduino block based programming?!

check this out: Minibloq This looks fantastic! I've downloaded it, it seems to work pretty good, I'm definitely going to have to pick up an Arduino or compatible dev board soon. I love the idea and if it works as good as it seems to, and makes relatively clean code which it seems to then its definit...
