  • Thermal layers and air currents...You might try borrowing a Halloween fog machine and inject the 'fog' (stage smoke) into your intake fan to see how the air is flowing.

    I would not be surprised if the intake fan is mixing up the hot vehicle air with the cooler intake air, which is giving the "Stabilized", yet still high temperature.

    As I see it the hottest air needs to be at the top, and the cooler air at the bottom. Perhaps a flexible dryer-type hose on the inside of the car for the intake fan to push air down to the floor? This would then only give the exhaust fan hot air to remove. At least in my mind. YMMV IANAE (I am not an engineer)

  • The best thing about Ham radio is that there is something for every Ham and Hams for pretty much anything you want to do.

    If you like making, electronics, communications, tinkering, yakking, computers, helping, community service, or collaborating, you can find it in Ham radio.

    I have spent endless (fun and frustrating) hours with a friend developing linux scripts to easily set up and configure a complete packet BBS system on Raspberry Pi.

    I enjoy providing communications for many local public events like bike rides, and running events, and they love to have us because we help make the events safe and run smoothly in challenging conditions. This and local emergency communications groups ARES/RACES are great for keeping skills up. (you haven't lived until you try being 'net control' for a disaster drill!)

    There are Ham radio clubs everywhere. Some are great, some are hard to fit in to, I'll be honest, but generally they are worth checking out.

    Getting a license is not difficult. With some study it's very achievable, and many clubs offer classes that start at the beginning and teach you the basics so you you have a better chance at understanding what it is you are doing (if you don't already).

    Come join the fun! (and don't let any grumpy, stodgy, people discourage you)

  • I would like to see more programming tutorials for those of us who are beyond the "Blink an LED" phase, and are starting more complicated projects, but are not experienced programmers. The visual programs are frustrating because you cannot add libraries, create functions, add new hardware, etc.

    A user friendly repository of code examples and libraries would help - Not github, but a web based listing of what you as developers have written, and libraries you think would be useful. It is a chore to look up several different tutorials and product examples to piece together code and try to make things work.

    Also, comments, comments, comments in your example code would help - over comment, state what each line does if you need to, but nothing is more frustrating than looking at code that assumes you understand all the uses of things like string, char, and pointers, etc. and there is no usable resource to figure it out. (and no, the arduino learning and reference sites don't count as they have very few examples and don't explain a lot of things well)

  • What about all the items that are showing out of stock with no time estimate for restocking? Seems kind of a bummer those items won't be available for the flash sale.

    If you are holding them back for the Monday sale you might want to update them and say that so we know they will be available Monday. Otherwise what is the point of putting them on sale with no backorder?

  • Having been crushed by the relentless taunting of the other kids, Pete slowly walked home, vowing he'd get his revenge! He'd show them he could build the mother of all AV's!

  • "With this board and the combined power of your shirts, I will complete my death ray for sure!"

  • SparkFun's new micro parts pickers - the secret to their uber cool pick n place machine.

  • Are you sure this will makes the solder ROHS compliant?

  • I won't order separately because I would have gotten free shipping, but not if I order just the pro 3.3 and 5v cards.

  • I can't believe what incredibly bad luck I have had on flash sales like this - I have been trying for years to get in on good deals, but I guess I'm just too slow - you know like 1 min. after the sale starts....
