Spot difference. Was wondering why it's consuming so much power and caps are getting hot

I took delivery of my first ever PCBs today! They looked pretty, but a stray trace on the board was causing a short… Little bit of work to clean it up and it’s working perfectly, couldn’t be happy for my first time!!

I've added an Elektronika 7-21-01 Soviet alarm clock to my family of VFDs (Vacuum Fluorecent Displays) from around the world, never enough of that aesthetic glow :)

Poorman's Digital Function Generator 8bit R2R DAC - Schematic and Build ...
![]() | I would like to share my DIY digital signal generator. I constructed it using an 8-bit R2R DAC to produce a variety of waveforms including sine, sawtooth, triangle, ramp, square, and noise. Additionally, you can create arbitrary waveforms. The signal generator's speed varies based on the waveform type and resolution. A full 8-bit sine wave can reach a maximum frequency of approximately 10-20 kHz, while other waveforms are slightly faster. If needed, the resolution can be decreased to achieve higher frequencies. I used a simple emitter follower as an output buffer. R2R DAC Digital Waveform Generator Typically, each unit(bit) of an R2R DAC consists of a pair of resistors, with the second resistor having half the value of the first. However, my R2R DAC is constructed using identical resistors, which eliminates the need for special values. Double the value of the first resistor by simply connecting two resistors of the same value in series. By doing so, R1 and R2 function as a 2K resistor. Any value between 1K and 100K will suffice, therefore, use the value that you have the most of. Maintain a consistent value throughout the entire R2R ladder. [link] [comments] |
bought an Anthem MCA 5 channel power amp for cheap since it was blown. Manufacturer wanted $700 plus shipping for a new main board, cue backyard engineering surgery ;)
