I’ve got a couple of those 1.14″ TFT/IPS displays in my box of lonely parts. There really isn’t anything magic going on with this clock other than the mechanical design, which is excellent. Even if they don’t open-source it, it’s going to happen anyway. The next very next day there might be a bunch of clock clones on Ebay for $20 each instead of $174. Yeah, the problem with open-sourcing something in China is cannibalism. It’s on a VLAN except for the peek-a-boo instance when it’s allowed to set itself which literally takes less than a second (fixed IP of course). I have an ESP8266 clock with a (real) DS3231 RTC that sets itself using the NTP pool once per day. I don’t understand the “regulatory (and now including security) hurdles”. Answer: Open-source it and let users add the feature.” “…because nice hardware and hackable for fun :-D” Yes hackable for fun does add value, it’s just at $174 the climb is too steep for me right L said: “True, for that kind of money (and considering it’s just software) not having NTP is really not acceptable… On the negative side, there are a lot of regulatory (and now including security) hurdles. Posted in clock hacks Tagged IPS display, nixie clock, nixie tube, nixie tube alternative Post said: “It runs an ESP32 if you look at the pictures.” Ah, didn’t notice that. Back in 2019 we covered the FIXIE (faux-Nixie) project which used OLED screens in a similar manner, but wasn’t quite as compact as this IPS panel approach. This earlier plywood-based clock uses edge illuminated acrylic digit panels to mimic the Nixie tube effect. This isn’t EleksMaker’s first attempt at a Nixie tube replacement. We wish more products would follow this trend. This is a selling point for many people, as this device doesn’t require a phone app for control. One beneficial side effect of having all these display is that changing the settings of your clock is no longer a cryptic experience - the displays are used to show and select options in clear text. While this is a finished product put out by EleksMaker, the concept is clearly adaptable to DIY projects as well. For example, if you don’t like the Nixie look, you can select from a suite of styles or make your own set of custom digits. The effect is quite impressive, and the fact that each digit is a complete display leads to quite a bit of flexibility. Based on ’s measurement of these displays, it appears they are the same 16:9 IPS displays used in the TTGO ESP32 modules. They are mounted like tiny billboards, each one inside glass bulbs to mimic that retro look. This is a re-imagining of a Nixie tube clock using six 135×240 pixel IPS display panels. 1 kohm for R8 may be too high for two LEDs, I suggest 220 ohm.Over on ’s YouTube channel he’s excited about a new gadget that finally arrived after months of waiting - the EleksTube IPS fake Nixie tube clock. Both registers need the signals RCLK (D8) and SRCLK (D7).Connect Q7S (QH#) of the first register to DS (SER) of the second to transfer the content.You don't need the shift register Master Reset (SRCLR#) inputs.This is also important for the 4 RGB dots. One issue may be noise in a radio next to your circuit. You can try later to remove some of them, if you want to know where stability issues start. It is good practice to place a capacitor from 100 nF up to 1 uF close to each chip between VCC and GND. It is important, that there is not again a long track between the IC and the capacitor. VCC1 shows a "dirty" supply of an IC without decoupling capacitor, VCC2 shows the effect of a capacitor close to the chip. The time domain simulation shows such a problem here: The influence on other circuits will be reduced. Simulate this circuit – Schematic created using CircuitLabĭecoupling capacitors stabilize the supply voltage at places where fast switching circuits have a high current demand for a short period of time. A capacitor does not allow a DC current to pass, so after power on there will be a short moment where the capacitor forwards the rising voltage but this voltage will drop to zero while the capacitor charges. In your schematic it is in the current path, between the regulator output and the load (the rest of the circuit). There is a capacitor C2 at the output of the LM7805, but it must be connected between the output and GND. You need more decoupling capacitors and a better understanding of the intention behind their use.
