Just to save anyone from searching for some secret mode on their calculators, I misspoke. I mention using my TI calculator in “Degree Mode”. I meant to say “Normal Mode”. It just happens to say DEG on the screen in tiny letters. What can I say, I’m easily distra
Oh look at that!
hpr2407 :: The Lost Episode Part 2
Released on 2017-10-24 under a CC-BY-SA license.A follow up to “The Lost Episode”. Flashing the blank Atmega328p chip to get bring a nonworking Transistor Tester Kit to life.
There are a lot of these kits out there. Different shapes, colors, and capabilities. In my case the kit was called a: 2578AY-AT. The firmware for this particular kit is:

http://blog.zakkemble.co.uk/avrdudess-a-gui-for-avrdude/Steps after plugging in the USB programmer:
lsusb (get bus and device ID numbers.) sudo chmod +777 /dev/bus/usb/*bus_ID/*device_ID avrdude -c ‘your programmer’ -p ‘your chip’
- In my case:
avrdude -c usbasp -p m328p
Avrdude should communicate with the programmer and verify the chip is ready to receive instructions.
From here Avrdudess helped as I was able to use the ‘verify’ options after a write to see there was an error. Avrdudess also let me correct the error by changing the E-lock value to 0x04. Then the flash would write.
Remember to write the hex file first and the eep file second as hex would over write a eep file if it was written first.
hpr2394 :: The Lost Episode
Released on 2017-10-05 under a CC-BY-SA license.NYbill puts up a ‘Lost Episode’ recorded in October, 2016. A comment for Ep. 2369 asking if I have ever built one of the many Transistor Kits available jogged my memory. I still had the recording so, I’ll just throw it up. I’m not sure how many pics I can find for the episode. I’ll put up what I can.
And just for Mike Ray, I’ll leave in some bench noises I would usually edit out. ;)

hpr2314 :: Bad Caps
Released on 2017-06-15 under a CC-BY-SA license.NYbill talks about repairing a motherboard.
Errata:
Even though I go into a bit about different types of capacitors I didn't plan on this being an episode about capacitors themselves. Even though I mention some different types. Bonus, there are also Trimmer Caps.
And yes, I know LCD's don't have a trace. The old school CRT user popped out there. You all knew what I meant.
Also, I know I mentioned getting a 90 piece cap set from Banggood. I decided to order proper Nichicon replacements from Digikey. Had this been a repair for myself, I would use the no name caps I ordered from China. But, being this repair is for a friend, I figured I better get the real deal. ...BTW they were 220 uf caps.
(Thanks Jezra for the musical interlude. We were joking calling it, "Time Passing".)

When I made the reference to "two red lips" regarding resistor colors I didn't quite explain what that meant. It was a way I learned, way back when, to remember which color was which number on a resistor. I hadn't thought about it in years. It used rhyming and references scheme to line the colors up with values.
0- Black - It's a "no" color, a zero 1- Brown - 'brow-one' 2- Red - Two red lips 3- Orange - Orange tree 4- Yellow - Yell for help 5- Green - a five dollar bill is green 6- Blue - Blue and sick 7- Violet - Violet heaven 8- Gray - Great 9- White - White wine

A few things I forgot to mention in the episode. The muriatic acid/hydrogen peroxide etching solution can be used multiple times. Store it in plastic or glass containers. The tinting fluid can also be reused. But, it will need to be agitated and or slightly heated (place container in a bath of hot water) before reuse as the mix will settle out.
