When [Stephen Cass] found himself with a broken Tandy TRS-80 Model 100 portable computer, the simplest solution was to buy another broken one and make one working computer from two non-working computers. However, this left him with a dilemma — what to do with the (now even more) broken one left over? Naturally, he did […]
TRS-80 MODEL 100 GETS ARDUINO HEART TRANSPLANT Read More »
Arduinos have been the microcontroller platform of choice for nearly two decades now, essentially abstracting away a lot of the setup and lower-level functions of small microcontrollers in favor of sensible IDEs and ease-of-use. This has opened up affordable microcontrollers to people who might not be willing to spend hours or days buried in datasheets,

Nexperia announced the market’s fastest common mode filter (choke)/ ESD protection combination. The new PCMFxUSB3BA/C features the industry’s widest differential passband of up to 10 GHz 3 dB frequency and very high surge robustness of up to 7.5 A 8/ 20 µs. It is designed to suppress common mode and single-ended noise while minimizing the
When [Robot Cantina] isn’t busy tweaking the 420cc Big Block engine in their Honda Insight, they’re probably working on some other completely far out automotive atrocity. In the video below the break, you’ll see them take the concept of a ‘lean burn’ system from the Insight and graft hack it into their 1997 Saturn coupe. What’s a lean burn

[Larry Wall], inventor of Perl, once famously said that programmers have three key virtues: sloth, hubris, and impatience. It’s safe to say that these personality quirks are also present in some measure in most hardware hackers, too, with impatience being perhaps the prime driver of great hacks. Life’s too short to wait for someone else

HelTec CubeCell is a new product series made by HelTec. CubeCell series is based on ASR605x ICs (ASR6501, ASR6502), those chips are already blended with the PSoC 4000 series MCU (ARM Cortex M0+ Core) and Semtech SX1262 transceiver. It is perfectly Arduino-compatible and can run the LoRaWAN protocol reliably. Connecting lithium batteries and solar panels are also a notable feature that comes

Coding wise all good but ive been searching and reading everywhere but still could not find how the HX711 converts voltage coming from the load cell into weight? is there a formula that converts voltage to weight ? if so whatt is this mathematical formula that the HX711 is using?I tried to see if maybe the arduino does the

The mass flow meter SFM4300 features improved sensitivity and precision, even for low flow rates. The small, compact sensor is calibrated for air, O2 and N2O gases and – in contrast to its predecessor, the mass flow meter SFM4100 – it can also be used to monitor gas mixing. With a zero-point accuracy of 0.005 slm for a total range of up

With digital semiconductor technology driving system power supplies to lower voltages for higher performance and lower system power, sensitive analog sensor circuits face a growing problem. Much of the inherent noise created in the early stages of an analog sensor signal path is independent of the amplifier bias voltage, so using a higher bias voltage
