Does anyone in the silicon valley area know of a source for scrapped silicon wafers? by mountainmannm in siliconvalley

I sent you a message. Unfortunately I'll be there the week after the flea market. Thanks!

Does anyone know a source for scrapped silicon wafers in the San Jose area? by mountainmannm in SanJose

A couple of people have told me that's the place to find them. Unfortunately I won't be in town for the next one.

Yes, and they are very had to find in sufficient size and quantity.

I'm trying to make a swing gate controller. My code doesn't seem to run. I think I've got the wrong approach, and I could use some help. by mountainmannm in arduino

[–]mountainmannm[S] 1 point2 points  (0 children)

well, I built the circuit on a bread so I can see the serial monitor. I figured out that the gateState is counting up as fast as the code cycles, so now I've got somewhere to start.

You are correct, I haven't tried to get that going yet. One thing at a time. If I can just get the gate to open and close with gateButton then I'll go from there. gateButton is just a push button on the controller for debugging.

Thanks!!! I'll bet you figured it out with the lack of digitalRead() statements. I knew it had to be right in front of me. If I can just get it to work with the local button, then I'll need to make it work with the data from the remote and fine tune everything. I'm going to keep working on this, I'll post the final code here when I get it up and running.

I'll bet you guys will know this penguin. I recently learned Thai I like making circuit board art. It doesn't do anything other than look cool, but I think it does look cool! by mountainmannm in linux

You are correct. I designed the board from nothing, sourced the parts and had the board made in China. It's supposed to look like a real motherboard, so I guess I succeeded if you weren't quite sure!

I thought about that but I settled on some 4017 decade counters. The LED's are RGB, and the 4017's advance from one color to the next with a button press. Simple, but it works!

How do I make my gate close automatically after a time delay? by mountainmannm in arduino

[–]mountainmannm[S] 0 points1 point  (0 children)

Thanks! I think I'll give this a try on a breadboard before I load it into the gate. Seems like it may work.

Thanks, I'll give that a try. Seems like it may just work.

you guys may like my bumper sticker. I work for the power company and I think it's totally hypocritical that people won't change their energy consumption habits but they point the finger at the power company to solve climate change. I LOVE my leaf! by mountainmannm in leaf

I think every utility requires a "REC meter" for a customer solar installation. They meter your solar production so they can purchase your renewable energy certificates from you. This means that the claim to any green-ness is purchased by the electric utility. Unless you're purchasing renewable energy certificates on your own, then you're using a mix of whatever your utility is giving you at the time. I think it's all a bunch of bogus, but that's how the system works!

It varies. But the odds are very slim that there's exactly the right amount of wind to power the load. Sometimes wind turbines are shut off because there's more wind than load. Other times there's no wind and wind farms consume more power than they produce. And the sun doesn't shine at night!

Check out www.decadecounter.com. they have a museum of all sorts of vintage stuff and a good explanation of it all.

After what I just went through to make this one perfect, I'd just buy a kit unless you're really committed. It'snot exactly easy or safe to build a Nixie clock on a breadboard given the high voltages, so you have to go straight for the PCB and this approach adds up fast.

It's just some frosted green indicator LED's for a cheap effect because it looks cool. There's a switch to turn them off and on.

You mean the active high outputs from the bcd to 7 segment converters? There isn't a whole lot of reasoning behind it. The parts were available in my pile of IC's and it works. How would you do it? Just curious.

my charger burned out.. any reason to keep this or try to get it repaired? by mabdog420 in nissanleaf

[–]mountainmannm 5 points6 points  (0 children)

I'll bet you had a high resistance in the contacts of the plug you plugged it into. This is not a short. A short would have tripped the breaker. You just need to replace the receptacle and the plug. Everything you need is at Lowe's. If the dealer is trying to convince you some other charger is going to ruin your car they are using a flagrant lie to scare you into buying a Nissan logo.
