Everyone likes to feel pleasant warmth, but it is relative. Not everyone is
able to say it’s too hot – let alone do something about it.
As well as allowing you to develop your soldering skills, our thermal alarm
will make sure that you know when, the temperature exceeds an acceptable,
preset value. When it is too high, i.e., rises above a preset threshold, the
device will start making a loud noise and the red and blue LEDs will start
flashing.
Specifications
- operating range: approx. -30°C…+150°C
- integrated buzzer
- two flashing LEDs (red and blue)
- supply voltage: 9 VDC [6F22] – batteries not included
- board size: 77×63 mm

Mounting and start-up
Figure 2 shows the arrangement of the components on the PCB. Solder the
components sequentially onto the board, starting with the smallest ones. The
R2 thermistor must be soldered above the board, while the LEDs must be
soldered by profiling their leads as shown in Figure 3. Once the circuit has
been mounted, check it carefully for correct installation.
Check that the components have not been soldered in the wrong direction or in
the wrong places and that no soldering points have been short-circuited during
soldering.
Heat sensitivity of the screamer can be adjusted with the PR1 potentiometer.
Recommended mounting order:
R1:…………………………………1 kΩ (brown-black-red-gold)
IC1: ……………………………….LM358 + base !
PR1: ……………………………..mounting potentiometer 10 kΩ
PIEZO:…………………………..piezo sounder !
ON/OFF: ………………………switch
R2:…………………………………10 kΩ thermistor (sensor mounted above the board)⊝
LED1, LED2: …………………5 mm LEDs ! battery connector red Ĺ, black
Components received in the kit, may differ in appearance from those shown in
the photograph. Despite this, they have the same parameters, and their
appearance will not affect their operation in the circuit.
Start mounting by soldering components on the board, in the order of their
size, from smallest to largest . When mounting components marked with an
exclamation mark, pay attention to their polarity. To access high-resolution

Mounting instructions
- Use the tip of a hot soldering iron to touch the leg/end of the component just outside the soldering field
- Then apply the “tin”/spoil
- Once the cone has formed, remove the ‘tin’ and then the soldering iron
- The entire process should take 2-3 seconds
The prerequisites for the formation of a correct solder are the cleanliness of the surfaces to be joined, the presence of flux in the binder, a sufficiently high temperature (320-360°C) and the correct amount of binder.
Too much binder will cause a bead to form or two adjacent solder points to
join.
Too low a temperature or amount of binder, as well as impurities, can lead to
“cold solders”, i.e. the binder and the flux contained in it do not wet the
surfaces to be joined and an impermanent solder is formed, which will oxidise
over time, a break will occur and the device will cease to function
