¿ªÔÆÌåÓý

I am going to FDIM and Dayton. ?I have read many posts about temperature of some chips. ?Does anyone have a suggestion as to a reasonably priced digital temperature gauge? ?I see the Harbor Freight has theirs on sale for $17.00 USD. I know that is cheap and probably not accurate enough to be useable. ?Any suggestions?

This is my Dayton list so far:

1) solder sucker
2) digital temperature gauge

Also, does anyone know if the "Maker Bar" in downtown Dayton is still in business. ?Two years ago it was written up in CQ and I visited it. ?It was a great place to hang out, build something, have a brew and make new friends. ?That night all the instructors were very nice ladies...... Another draw for the young "Maker" guys. ?When I talked to the manager he had hopes of franchising this idea to other large cities. ?They sold kits, had a dozen or so soldering stations with air cleaners, high intensity lights, vices and 3 different types of 3D printers, and instructors who did not charge for their assistance. ?Newbies welcome. ?They even gave away little skeleton head pin kits with eyes that would blink and change colors. ?What a hoot.

Oh yes I remember now I added one here because I wasn¡¯t happy how hot that regulator was getting. I think I measured the temp at over 110 degrees F. Nice set up you have.

SD: ?"I noticed you removed the heat sink on the regulator on the Raduino"
... I didn't know it needed a heatsink, it didn't come with one, meaning I haven't removed it. ?I haven't notice them on the pictures when looking around. ?I'll monitor the heat and install a heatsink and/or install the resistor. ?If I was doing serious QRP, I'd probably install a second battery pack closer to 5v to run the Raduino.
