Watch out for scam component distributors in China
Finding components is hard enough these days and it’s pretty easy to get drawn in by very elaborate Chinese websites that show stock and keen prices. However never entertain them if the insist on wire transfer of funds. There is a high risk that once you have sent your money you’ll never hear from them again and you will receive no goods.
Here is a link to the ERAI site that lists a lot of these sites and the bank account names they use. Worth a quick check before you buy !
Now running V23 the very latest version of EasyPC. https://www.numberone.com
Ever wondered how a PCB is made ?
Well have a look at the video below from the giant JLC plant in China.
HY-PAC HYDROSTATIC PRESSURE AUTOMATIC CUT-OFF
Very pleased to have been involved in the complete design/firmware/PCB development for OCTOPUS TEST SYSTEMS for their HY-PAC (Hydrostatic Pressure Automatic Cut-off).
The HY-PAC (Hydrostatic Pressure Automatic Cut-off) provides an overpressure control capability for hydrostatic test systems where multiple test pressures and hence over pressure settings are required. The system features a contact gauge fitted into the hydrostatic pressure circuit and a control box fitted into the low pressure hydro pump air supply and is powered by a standard mains supply. The contact gauge is set to the desired over pressure by moving the needle to the required pressure on the gauge scale, if during testing an over pressure situation occurs the contact gauge trips sending a signal to the control box which in turn closes the internal solenoid valve which isolates the air supply to the hydropump and hence stops the hydrostatic pressure from increasing any further. Upon closing the solenoid valve the internal timer also begins and after 30 seconds a buzzer activates indicating to the operator that hydrostatic pressure can now be removed manually. If during this 30 second hold period the hydrostatic pressure drops such that the contact on the gauge is released the ‘fault’ LED illuminates indicating that the system under pressure is not able to hold a hydrostatic pressure and would more than likely indicate a leakage. If during operations a power cut occurs the control box solenoid will immediately close which will stop the hydro pump hence ‘failing safe’. Retro fitting HY-PAC into existing systems is relatively simple and in most cases the standard working gauge can be directly replaced with the HY-PAC contact gauge, the control box wall mounted and fitted in-between the LP air supply feeding the hydro pump. The contact gauge is then connected to the control box via a right angled plug and the power adapter (supplied) connected to a mains supply and the system is ready to go.
Amazing to think that Wilkie Electronics has been around for such a long time.

We are now running the latest EasyPC V22 for all our schematic capture and PCB layouts. Keeping up to date with these design tools ensures the very best features and continued technical support which is paramount in this type of service.
Why not have a look at the new EasyPC V22
Been busy over the Winter months with various exciting projects.
Had to venture into the world of the analogue domain and discovered a fantastic simulation tool called Tina.
The full DesignSoft version allows analogue, digital and mixed mode simulations and can import Spice models from any manufactures that supply them.
There is also a cloud based version called TINACloud that allows you to run simulations from any PC, tablet or even a mobile phone !
The support from DesignSoft is absolutely excellent, and I can highly recommend.
Delighted to have been invited by Number One Systems to do another blog for them.
This time it's things to consider when laying your tracks down.
