2023.06.07 11:20 Netherlab Programming ESP8266 (ESP-01 module), but it's returning gobbledygook afterwards
So I am using the esptool.py program to write the firmware to my ESP-01 module. I identified it has a 1MB flash size:submitted by Netherlab to esp8266 [link] [comments]
Flash size = 1MB
...so I am using the corresponding firmware with Flash size 8Mbit (512KB+512KB), (firmware was found here: https://github.com/Edragon/esp_firmware/blob/masteFirmware/AT-espressif/NonOS/V1.7.4-ESP8266_NonOS_AT_Bin_V1.7.4.zip):
So I use the corresponding command to flash the memory:
Using esptool.py to write the binary files to the flash
When I pull the GPIO-0 pin back to Vcc, reset the module with the CH_PD pin pulled low and then to Vcc again, you can see the module's blue LED go absolutely apesh%*. The output of the Arduino serial monitor is the following endless jargon:
Arduino serial monitor
I have tried multiple other binary files, some at least don't go apes$@% and just prints gobbledygook once. Still no response when I use the AT commands such as AT+GMR.
More possibly useful info:
I am using an FT232R to write the binary files.
I bought the module on AliExpress (do they supply duds?)
I never supplied it with the 5V which so famously would fry it. The FT232R's jumper is set to 3V. I also checked all the voltages with my oscilloscope and they run at 3.3V.
I am currently powering it with the Vcc from the FT232R (does it need more current?), but I did use a separate power supply and that didn't work, quite an old adaptor but it can supply 1000mA.
Any help would be much appreciated!

The scheme has the advantages of low cost, low investment and simple installation and wiring, which is beneficial to the further popularization and application of low voltage intelligent distribution.
Keywords: Split core current transformer; Low Voltage Distribution System; Renovation Project; Principle; Application; Construction Details
At present, most of the low voltage current transformers in the market are mainly used in the construction of new projects. Due to the rapid development of economy, the awareness of energy saving and emission reduction is gradually improved. The electrical characteristics of many enterprises are:
1）Long running time of electric gas cabinet;
2）Most of the current transformers only measure the current of the system, and there is no corresponding metering device and protection device. The measuring device has only one master table of the power supply bureau, but the electric energy of all workshops can not be assessed, and the system line protection device is not available at all,;
3）Most of the main lines are large size copper bar, it takes a lot of manpower and time to disassemble, it is not convenient to install conventional current transformer;
4）Enterprise production time is more urgent, can not long time blackout.
Therefore, the use of split core current transformer can save a lot of investment for users.
1）结构特点 Structural characteristics
Our company has a complete range of split core current transformer models, including round hole transformers for cables, and square hole transformers for copper bars., this product shell material is PC/ABS alloy, with high temperature resistance, high mechanical strength, environmental protection and other characteristics; The core adopts oriented cold bonded silicon steel sheet with stable performance, high mechanical strength and high magnetic conductivity.

2）开口电流互感器工作原理Working principle of open current transformer
The working principle of the low voltage split core current transformer is shown in figure 1, The primary winding of the split core current transformer is connected in series in the line under test, I1 is the primary current of the current transformer, N1 is the primary turn of the current transformer, I2 current transformer secondary current (usually 5 A、1A), N2 is the secondary turns of the current transformer, Z2e for secondary circuit equipment and connection wire impedance. As the primary current flows through the P1 end of the current transformer, P2 out, If the secondary Z2e is connected, Based on electromagnetic induction, The secondary winding of the current transformer has current I2 flowing through the S1, Z2e to S2, Form a closed loop. Hence the I1×N1=I2×N2, of current in ideal state And so there's I1/I2=N1/N2=K, K is the ratio of current transformer. But since the core of the open current transformer is cut, Make the core performance will be more powerful, So the cross section of the transformer core must be increased, And increase the number of turns, I1×N1=I2×N2≥100 AN.
Note: Figure 2- Upper body of the 1- Open current transformer ,2- Lower body of the 2- Open current transformer ,3- Install screws, nuts
As shown in figure 2, the installation screws and nuts of the transformer are opened, the lower body of the transformer is unloaded, the upper body of the transformer is loaded into the primary bus row of the distribution system, the lower body of the transformer is closed, the installation screw of the transformer passes through the fixed hole of the upper and lower body of the transformer, the nut is screwed, the upper and lower body of the transformer is fixed together, and then the transformer is fixed on the bus row through the installation fixing hole on both sides of the transformer to complete the installation of the transformer. Then connect the secondary of the transformer to the measuring device. The whole process is relatively fast and simple.
Split core current transformer is mainly used in the low voltage distribution transformation project. Split core current transformer is output as standard 5 A or 1 A, as the conventional closed current transformer. The measuring precision is high and the capacity is large.

2023.06.07 08:05 richi-carmen Why should fowl feed processing maker lubricated?
Chicken feed handling equipment makers all know that throughout the operation of the feed machinery, there will certainly be equivalent rubbing in between the components touching each other, from damages to the parts to affecting the production of mechanical devices, hence causing the mechanical equipment to stop working and also causing significant economic losses to the business. Therefore, routine lubrication is usually needed to guarantee the regular procedure of the pet feed pellet making device.submitted by richi-carmen to pelletmachinery [link] [comments]
When oiling feed machinery, fowl feed handling equipment manufacturers generally consist of a number of different lubrication states, which can be separated into border rubbing, completely dry rubbing and also liquid rubbing. Typically speaking, oiling the friction parts of tools can properly decrease friction, greatly decrease tools wear and also performance intake, boost devices operating efficiency, as well as extend equipment life. As one of the major ways to enhance devices efficiency, lubrication modern technology has ended up being a common problem in related areas.
Chicken feed handling machine makers require to take note that in the process of lubrication, they must not be thoughtlessly executed, but need to formulate a lubrication management plan in accordance with the development of the business according to the real production situation of the poultry feed equipment itself, so regarding make greater efforts for the typical operation of the enterprise equipment. contribution.Why should the chicken feed pellet making maker be kept oiled?
Generally, the importance of lubricating treatment has been highlighted again and again, mostly due to the fact that appropriate lubricating treatment can substantially decrease the wear degree of feed pellet mills and make certain smooth manufacturing job. As we all recognize, any kind of poultry feed processing equipment will inevitably have troubles such as reduced flexibility, reduced operating efficiency as well as damage after long-term usage. At this time, the maintenance of equipment certainly squanders labor and also material resource expenses, and also creates ventures to endure better economic losses.
Chicken feed processing makers are no exemption. In the long-lasting usage procedure, if there is a absence of corresponding lubrication, the friction stamina in between the get in touch with parts will unavoidably boost, resulting in damage to the parts and also impacting the typical use of the entire fowl feed handling equipment. Therefore, having a good lubrication program in place before a issue takes place in the equipment will certainly be a preventive measure to extend the life of the devices.

The Followings Are More Frequently Asked Questions concerning Chicken Feed Pellet Machines ：.
With the opening of 2022, the sales of Richi Equipment's fowl feed handling equipments have actually been increasing progressively. However, for the small troubles caused by the wrong procedure of clients, a brief recap is as complies with:.
1. What should I do if the poultry feed handling equipment can not be pushed?
Encountering this problem, numerous close friends will absolutely assume that this scenario will also take place when their feed pellet devices are generating feed pellets. This is actually a headache, not just wasting raw materials, but likewise considerably raising the trouble of screening feed pellets. Today, a technologist will certainly go over the factors for this sensation with you.
Lately, several customers reported that the fowl pellet maker created a great deal of powder, as well as the pellets were not tight enough, the feed pellets were always soft, so what happened?
In general, is this considered a feed component or formula? Relatively slow-moving production modifications, or changes to dishes, can promptly accomplish the wanted results. Omitting feed ingredients and also solutions, we will certainly evaluate the maker setup for internal issues.
( 1) The mold and mildew wear is too large, the filter holes are flattened, and also the expansion is significant, resulting in a decline in pellet stress, impacting the pellet forming price, and causing excessive powder.
( 2) The wetness web content of the raw material is too low or expensive. If the water content is too expensive, the powder will not be excessive, yet the pellet hardness is reduced, and also the pellets of the fowl feed pelleting device are easy to loosen up. The raw product has a low water content and is tough to squeeze out, leading to way too much powder.
( 3) The poultry feed pellet maker is aging, the power is insufficient, the motor can not give enough rate, as well as the matching stress is generated to press right into pellets.
( 4) The top quality of the ring die is bad, or the compression is not too high.
( 5) Think about making use of grease.
( 6) The feeding scrape is not set up correctly, and the feeding can not go into the pressing chamber.
( 7) The placement of the cutter is wrong, and the discharge material is squeezed right into powder ( yet if the hole is commonly blocked, it is unlikely).
( 8) Moisture control describes the comprehensive control of various aspects according to different situations in the entire production process, so that the final water material of the item can get to the anticipated target of the manufacturer. The main variables impacting the final water material of feed products are: water material of feed components, water changes in the squashing stage, fluid addition in the mixing phase, steam water material, conditioning degree, die hole size as well as thickness, cooler air quantity and air-drying time, product packaging.

The influence of high quality administration and also different weather and environmental aspects ( usually, the dampness web content of pellet feed after handling will not go beyond 12.5; but in the north, pellet feed will not go beyond 13.5. If handling in summertime, due to the high ambient temperature, the optimum dampness content of ended up pellets shall not exceed 13.5. 12.5, otherwise it is very easy to mold and mildew and wear away).
Feed pellets rate by more and more farmers as well as herdsmen with their distinct advantages. It is simple to shop as well as transport, and it is also helpful for pet food digestion. Compared with ordinary feed, it is rich in nutrients and also has a good market possibility. Actually, the manufacturing procedure of feed pellets is a process of distribution ratio, as long as you master the proportion. Certainly, when the pellets begin, obviously inexperienced, but do it two times. The basic poultry feed handling machine maker's handbook will discuss the distribution ratio of feed pellets, which can be described.
2. No pellets.
（ 1 ） Reason.
The new poultry feed handling maker was not run-in with lubricating oil or was not run-in sufficient;.
The moisture web content of feed raw materials is expensive;.
（ 2 ） Option.
Remove the raw materials in the existing fowl feed processing machine, as well as add oil to the raw products to run in the brand-new maker, and the proportion of each time is: 1:3.
Add some dry active ingredients to readjust the wetness.
3. The electric motor quits all of a sudden.
（ 1 ） Reason.
The voltage is as well low.
The pressure between journalism roller as well as the die plate is expensive.
（ 2 ） Option.
Usage 4mm cable to avoid tripping throughout use.

2、关于设置 IT 隔离电源系统的相关规范要求
Specification requirements for setting up IT isolated power system
随着社会经济的不断发展，大型综合型的现代化医院不断投入建设，因而医院电气安全可靠也引起来业界的重视，其中关于 ICU、手术室等重要场合的配电安全可靠越来越引起业界重视。尤其是关于IT隔离电源的设置。GB16895.24-2005/IEC60364-7-710:2002 标准中规定，在医疗领域2类医疗场所内，用于维持生命的、外科手术的和其他位于“患者区域”内的医疗电器设备和系统的供电回路应选用带绝缘监视的医疗IT系统供电。2008年8月1日正式实施的《民用建筑电气设计规范》中12.8.6对医疗场所采用的IT系统供电做了相应要求和规定。
With the continuous development of society and economy, large comprehensive modern hospitals are constantly put into construction, so the electrical safety and reliability of hospitals have also attracted the attention of the industry.The safety and reliability of power distribution in important occasions such as ICU and operating room have attracted more and more attention from the industry. Especially with regard to IT isolation power Settings.According to gb16895.24-2005 /IEC60364-7-710:2002, the power supply circuit for life-sustaining, surgical, and other medical electrical equipment and systems located in the "patient area" in class 2 medical facilities in the medical field shall be powered by medical IT systems with insulation and monitoring.12.8.6 In the Civil Building Electrical Design Code officially implemented on August 1, 2008, the corresponding requirements and regulations are made for the POWER supply of IT system used in medical places.
In class 2 medical facilities, the medical IT system shall be used for the power supply circuits for life-sustaining, surgical and other medical electrogas equipment and systems located in the "patient area".

3、IT 隔离电源系统简介及医院采用的重要性 Introduction of IT isolated power system and importance of hospital adoption
IT isolates the power system, and I indicates that the power side is not working grounded, or is grounded through high impedance.T represents the grounding protection of the electrical and gas equipment at the load side.IT system in the power supply distance is not very long, the reliability of power supply is high, good security.Generally used in places where blackouts are not allowed, or where strict continuous power supply is required, IT systems must be used in hospital operating rooms, emergency rooms, ICU rooms, and other type ii places.The use of IT mode power supply system, that is, the neutral point of the power supply is not grounded, once the equipment leakage, single-phase leakage current to the ground is very small, will not destroy the balance of the power supply voltage, so IT can avoid electric shock and other electrical accidents, at the same time is not enough to make the circuit protection electrical equipment action cut off the power supply, to ensure the uninterrupted power supply.So than the power neutral grounding system is safe and reliable.
The importance and necessity of using isolated power systems in hospitals.
而在一般通用建筑中所采用的对地漏电保护开关，其动作响应值是mA 级（如：30 mA），远远不能满足医疗领域的需要。在医院的特殊环境里，漏电流对病人构成了潜在的危险，因此对电气安全设计也提出了特殊的要求。尤其是那些生命攸关的场所，如外科手术室、重症监护室、心脏手术室等地均需安装医用IT隔离电源系统，其目的就是为了保证对该场所内的医疗电器提供一个安全可靠的电源，以确保病人的安全。在导电体触及到心脏(例如，打开心脏的手术或埋置心脏起搏器)时，在普通安全接地的导体之间流过的细微电流会造成微电击和死亡的可能。隔离变压器就象一个门一样，将医疗地区的非保护区域和保护区域的电气线路隔开，保护区域内所有带电导体是与地隔离的，防止线路绝缘层上危险电流造成微电击。绝缘监视仪必须与隔离变压器配合使用，用来连续监视隔离变压器二次侧的带电导体与地之间的电阻及电流，例如，手术过程中流出体外的血液和金属制的手术台可能会使病人与地形成一个通路，这样就存在预期危险电流，一旦医疗电子设备的导电体也形成对地通路(如漏电)，将会造成宏电击(不是所有电流都流经心脏)或微电击(所有电流都流经心脏)。一般供电电网是以大地作为参考电位，相线中的电流可以通过任何未绝缘的通道，对地构成回路，这是电击的根本原因。隔离供电是采用隔离变压器供电，电源经隔离变压器后，原电网中的地已不再是参考电位了。隔离变压器任何一根输出线都不能与地构成回路，只能在两根输出线之间构成回路，这就提高了供电的可靠性。用隔离变压器以分隔非保护区域与保护区域，在隔离变压器的次级引出IT系统的电源，以防止产生接地故障电流。将IT系统引入手术室或急救室，在房间内设一配电箱，箱内放置绝缘监视仪，绝缘监视仪的使用可以及早的显示隔离变压器次级负载部分的绝缘状况，在发生绝缘故障对人身构成威胁前就提供报警信号。而此时电源不会被切断，保证了供电的连续性，医护人员此时可以根据监视仪上显示的漏电流大小和手术的实际情况及时处理，因而人身触电的危险被降低到了最小。
It is well known that when the direct leakage of electrical equipment to the human heart is greater than 10uA, it will cause a micro-shock accident to the patient.
However, the action response value of the earth leakage protection switch used in general general buildings is mA level (such as: 30 mA), which is far from meeting the needs of the medical field.In the special environment of hospital, leakage current poses a potential danger to patients, so special requirements are put forward for electrical safety design.In particular, those vital places, such as surgical operating rooms, intensive care units, cardiac operating rooms, etc., need to install medical IT isolation power system, the purpose of which is to ensure a safe and reliable power supply to medical appliances in the site, so as to ensure the safety of patients.When the conductor touches the heart (for example, during open-heart surgery or embedding a pacemaker), the tiny currents flowing between normally safely grounded conductors can cause micro-shocks and the possibility of death.The isolation transformer acts as a door separating the non-protected area of the medical area from the electrical wiring in the protected area. All live conductors in the protected area are isolated from the ground to prevent the dangerous current on the line insulation from causing a micro-shock.Insulation monitors must be used together with the isolation transformer, used for continuous monitoring isolation transformer secondary side of charged conductor and earth between the resistance and current, for example, in the process of the operation flow of blood and in vitro metal table may make the patient and to form a path, so there are dangerous currents, once the conductor in the medical electronic equipment form of pathways (such as leakage), will cause the macro electric shock (not all current flows through the heart) or micro electric shock (all electric current flows through the heart).Generally, the power supply network takes the ground as the reference potential, and the current in the phase line can pass through any uninsulated channel to form a circuit to the ground, which is the root cause of electric shock.Isolated power supply is the use of isolated transformer power supply, power through the isolated transformer, the original grid is no longer a reference potential.None of the output lines of the isolating transformer can form a circuit with the ground, but can only form a circuit between two output lines, which improves the reliability of power supply.The isolating transformer is used to separate the unprotected area from the protected area, and the power of the IT system is extracted at the secondary of the isolating transformer to prevent the generation of ground fault current.The IT system will be introduced into the operating room or emergency room, and a distribution box will be set in the room, and insulation monitors will be placed in the box. The use of insulation monitors can show the insulation status of the secondary load part of the isolation transformer as early as possible, and alarm signals will be provided before the insulation failure poses a threat to the person.At this time, the power will not be cut off, to ensure the continuity of power supply.Medical staff can then monitor the leakage current and the actual operation, so that the risk of personal shock is minimized.
