Op amp tester

I was watching How To TEST OP AMPS Using A Multimeter vs Op-Amp Tester Project Single Dual and I learned about this Operational Amplifier OP AMP Tester For Single Dual OPAMP TL071 TL072 TL081 TL082 Single/Dual Op Amp Test Board.

I have to cool it on the spending for a little while, but I’ve made a note of this on my shopping list.

Studio upgrade

The computer I’m using to do the recording for In The Lab With Jay Jay is called ‘wonder‘ and it only has six USB ports. I currently have ten USB cameras, and I’m getting more, so I don’t have as many USB ports as I can use. Also ‘wonder’ only has 2TB capacity (non-RAID) for storing the videos I record, which will probably get used up fairly quickly.

So I have been planning an upgrade for ‘wonder’ known as ‘victory‘. My new studio workstation ‘victory’ will have 52TB of RAID storage for video data, 2TB of SSD RAID storage for video recording, 12x USB ports on the back panel, and 4x USB ports on the front panel.

Along with this new studio workstation I intend to get a new camera, a Canon Rebel SL3.

Now all I need to do is save up a cool eight grand!

Etudes for Programmers

From time to time I swing by norvig.com looking for signs of life from Peter Norvig, but it hasn’t been updated in years. However today I pushed on the internet a bit harder and I found signs of life over at github.com/norvig. Norvig continues to hack on his pytudes project, which is cool. I was reading its documentation today and I learned about the book Etudes for Programmers. If I had more money I would definitely buy myself a copy of that book, but at the moment AUD$355 is just a tad out of my league.

CRC

I watched Ben Eater’s videos How do CRCs work? and Checksums and Hamming distance (the full course is Learn about error detection) then found the Wikipedia page: Cyclic redundancy check.
